Consumo de alimentos ultraprocessados fora de domicílio no Brasil / Ultra-processed food eaten out in Brazil

Giovanna Calixto Andrade 28 June 2017 (has links)
Introdução: Comer fora de casa tem sido relacionado com o aumento no consumo de alimentos caracterizados pelo alto grau de processamento, tal como refrigerantes, doces e fast food. Embora indiquem uma associação entre alimentação fora do domicilio e o consumo de alimentos ultraprocessados, estudos realizados até o momento não consideraram o grau e extensão de processamento industrial dos alimentos na avaliação da dieta fora de casa. Objetivo: Avaliar o consumo de alimentos fora de casa e verificar sua associação com características socioeconômicas e indicadores nutricionais. Métodos: Trata-se de um estudo transversal utilizando o Módulo de Consumo Pessoal da Pesquisa de Orçamentos Familiares realizada pelo Instituto Brasileiro de Geografia e Estatística entre maio de 2008 e maio de 2009. Os alimentos foram agrupados de acordo com a extensão e propósito do processamento industrial. O hábito de comer fora de casa foi avaliado por meio de dois indicadores: o percentual de calorias consumidas fora e a frequência de dias em que cada indivíduo relatou realizar refeições fora de domicílio, ambos descritos segundo características sociodemográficas. Foi estimado o percentual de participação dos grupos e subgrupos alimentares no total de calorias e segundo local de consumo. Adicionalmente, o percentual de participação de alimentos ultraprocessados dentro e fora de casa foi descrito segundo características sociodemográficas. Modelo multinível foi aplicado para avaliar a associação entre comer fora de casa e a participação de alimentos ultraprocessados na dieta. Análise fatorial foi conduzida para identificar padrões de alimentação fora de casa e modelos de regressão linear foram utilizados para explorar associação entre os padrões encontrados e indicadores nutricionais. Resultados: Observa-se uma maior contribuição de alimentos ultraprocessados fora de casa, destacando a participação de itens alimentares como refrigerantes e refeições prontas. Quando comparado com o consumo exclusivamente dentro do domicílio, realizar refeições fora de casa aumenta em 51% o consumo de alimentos ultraprocessados. A análise de componentes principais, no entanto, monstra que existem padrões de alimentação fora de casa que podem ter ou não um impacto negativo na dieta. Foram encontrados três padrões de alimentação na população que explicam conjuntamente 13,6% da variância. O primeiro padrão, denominado refeição tradicional, inclui em sua composição arroz, feijão, legumes e verduras, raízes e tubérculos, macarrão e outras massas, carne bovina, aves e ovos. O segundo padrão, nomeado lanche, é composto por manteiga, leite, café e chás, pão francês, queijos processados e margarina. O terceiro padrão, denominado alimentos de conveniência por ser composto exclusivamente por alimentos ultraprocessados, inclui doces, refeições prontas (tais como fast food, salgados, pizza, entre outras) e refrigerantes. De maneira geral, observou-se uma associação direta entre o padrão de refeições tradicionais e nutrientes saudáveis na dieta, enquanto o padrão lanches e alimentos de conveniência foram associados diretamente com nutrientes não saudáveis. Conclusão: Os resultados apresentados indicam que no Brasil, comer fora de casa está associado ao aumento na participação de alimentos ultraprocessados na dieta. Existem, porém, padrões de alimentação fora de casa. Quando baseada em lanches e alimentos de conveniência, comer fora de casa acarreta em um impacto negativo na dieta. É, no entanto, possível manter uma alimentação saudável fora de casa quando se adere a padrões tradicionais da culinária brasileira / Introduction: Eating out has been related to the increase on the consumption of food characterized by high degree of processing, such as soft drinks, sweets and fast food. Although they indicate an association between eating out and ultra-processed food consumption, studies do not consider the extent and purpose of food processing to evaluate eating out diet. Objective: Evaluate eating out food and verify its association with socioeconomic characteristics and nutritional indicators. Method: Cross-sectional study using the Individual Food Intake Survey, carried out with 34,003 individuals aged 10 or more, between May 2008 and May 2009. All food items were classified according to the extent and purpose of food processing. The habit of eating out was evaluated through two indicators: the percentage of calories eating out and the frequency of days in which each individual reported eating out, both indicators are described according to the sociodemographic characteristics. The percentage of food calories per group and subgroups was estimated according to the place of consumption. In addition, the ultra-processed food percentage eaten at home and out was described according to sociodemographic characteristics. Multilevel model was applied to evaluate an association between eating out and the participation of ultra-processed food on diet. Factor analysis was used to identify the eaten out food consumption patterns and linear regression models were used to explore the association between patterns and the nutrient content of the diet. Results: It is possible to observe a higher contribution of ultra-processed food out home, emphasizing the participation of food items such as soft drinks and ready-to-eat meals. When compared to consumption exclusively at home, eating meals out increases the consumption of ultra-processed foods by 51%. Principal component analysis, however, demonstrates that there are eating out patterns, whether or not may have a negative impact on the diet. We identified three food patterns. The first pattern, called traditional meal, was positive for rice, beans, vegetables and greens, roots and tubers, pasta, beef, poultry and eggs. The second pattern, called snack, was positive for butter, milk, coffee and tea, processed bread, processed cheese and margarine. The third pattern, called convenience food because it consists exclusively of ultra-processed food, was positive for sweet, ready to eat meals and soft drinks. In general, there was a positive association between traditional meal pattern and healthy dietary markers, while snacks and the convenience pattern were positively associated to unhealthy dietary markers. Conclusion: In Brazil, eating out is directly associated to ultra-processed food consumption. There is, however, eating out patterns. When based on snacks and convenience food, eating out has a negative impact in diet. It is, however, possible to maintain a healthy diet out when adhering to traditional Brazilian patterns

The validity of value-added measures in secondary schools

Scherman, Vanessa 19 September 2007 (has links)
The issue of quality education is a critical topic of discussion, for South Africa facing the challenge of implementation amidst a plethora of progressive policies. This research project is undertaken in collaboration with the Curriculum, Evaluation, and Management Centre (CEM) at Durham University in the United Kingdom. The Middle Years Information System (MidYIS) project was developed with the aim of providing schools with information on how learners would perform at the end of two national examinations namely Key Stage 3 and General Certificate in Secondary Education, in addition to providing value-added information. The purpose of the research reported here is to describe the procedures undertaken to explore the feasibility of implementing the MidYIS system in the South African context. The research was guided by two main research questions. The first research main research question is how appropriate is the Middle Years Information System (MidYIS) as a monitoring system in the South African context? The word “appropriate” here interrogates the suitability of the MidYIS system for South Africa looking specifically at validity and reliability issues. This non-experimental study used a mixed methods design, rooted in pragmatism, to explore validity and reliability issues of using MidYIS as a possible monitoring system that would provide a balanced view of the school’s contribution to academic gains made by learners. The sample included in the study ranged from National Department of Education officials (two officials from curriculum and assessment), Provincial Department of Education officials (one mathematics specialist, one language specialist and one specialist from the Gauteng Department of Education Office for Standards in Education), specialists in the field of language, mathematics, and psychology as well as 11 schools. In particular content-related validity (including curriculum validity), construct-related validity, and predictive validity were examined while inferences drawn with regard to reliability were done by means of internal consistency reliability. From a curriculum perspective for content-related validity, it was found that there was moderate curriculum validity for language while inferences drawn for mathematics were substantially stronger. For content-related validity from a psychometric perspective, it was found that there was overlap between the domain of developed abilities and the MidYIS assessment. Construct-related validity was explored by means of Rasch analysis and it was found that items in the MidYIS assessment tend to form well-defined constructs. Predictive validity was explored by means of correlation analysis between the MidYIS assessment and school-based results in language and mathematics. The analysis shows that it could be possible to use the MidYIS assessment for prediction purposes. However, additional research would be needed to explore this facet of validity further with a larger sample and using standardised school-based results. The MidYIS assessment was found to be reliable for the sample as a whole as well as for population groups within the sample. The second main research question extends the first research question. If MidYIS is valid, with South African adaptations, and reliable, then what factors on a school, classroom, and learner-level could have an effect on learner performance. Thus, the second main research question is which factors could have an effect on learner performance and therefore inform the design of the monitoring system? In order to explore factors, multilevel analysis was undertaken on the various levels within the school system namely the principals, mathematics and language educators, as well as learners who completed questionnaires. It was found that four learner-level factors (with whom learners live, mother’s level of education, importance of mathematics and importance of English), one educator level factor (challenges to assessment due to lack of in-service training) and two school-level factors (educators make use of monitoring systems and encouraging academic achievement) seem to have an effect on the performance of learners. / Thesis (PhD (Assessment and Quality Assurance in Education and Training))--University of Pretoria, 2007. / Curriculum Studies / PhD / Unrestricted

Estimation de l'Incidence de l'Infection par le VIH et autres Indicateurs de Surveillance de l'Épidémie du VIH : le cas de la France et du Cameroun / Estimation of HIV incidence and others indicators of surveillance of the HIV epidemic : the case of France and Cameroon

Ndawinz, Jacques Deval Armstrong 07 July 2015 (has links)
Une solution envisageable pour éliminer la propagation de l'épidémie du VIH est que les personnes vivant avec le VIH (PVVIH) ignorant leur statut sérologique (épidémie cachée) soient diagnostiquées et que les PVVIH aient accès rapidement au traitement antirétroviral (TARV). C'est pour cette raison qu'il est recommandé de mettre en place les interventions combinant notamment le dépistage précoce du VIH et l'initiation précoce du TARV. L'objectif de cette thèse est de développer des méthodes statistiques pour estimer les indicateurs permettant de désigner, de suivre et d'évaluer ces interventions dans différents contextes épidémiques. Ainsi, un premier modèle de rétrocalcul combinant les données de diagnostic du VIH et les changements dans l'accès au dépistage est développé, avec une application en France, pour estimer l'incidence de l'infection à VIH, la durée entre l'infection et le diagnostic du VIH et la taille de l'épidémie cachée. Une analyse multiniveaux est mise en œuvre pour identifier les facteurs de risque d'accès tardif au TARV au Cameroun. Une méthode basée sur les modèles multiniveaux est proposée, avec une application au Cameroun, pour estimer deux nouveaux indicateurs, la durée entre la seroconversion et l'initiation du TARV et la durée entre l'éligibilité théorique au TARV et son initiation effective. Un second modèle de rétrocalcul plus adapté aux pays d'Afrique est développé à partir des données des PVVIH mises au TARV, avec une application au Cameroun, pour estimer l'incidence de l'infection à VIH. Cette thèse propose des méthodes originales pour estimer l'incidence du VIH et le délai entre l'infection et le diagnostic du VIH ou l'initiation du TARV. / A possible solution to eliminate the spread of the HIV epidemic is that people living with HIV (PLHIV) unaware of their HIV status (the hidden epidemic) are diagnosed and that all PLHIV have timely access to antiretroviral treatment (ART). That is why it is now recommended to put in place interventions combining early diagnosis of HIV and early initiation of ART. The objective of this thesis is to develop statistical methods to estimate indicators to identify, monitor and evaluate these interventions in different epidemic settings. Thus, a first back-calculation model combining HIV diagnosis data and changes in access to HIV screening is developed - with an application in France -to estimate the incidence of HIV infection, the duration between infection and HIV diagnosis and the size of the hidden epidemic. A multilevel analysis is implemented to identify risk factors associated with late ART initiation in Cameroon. A method based on multilevel models is proposed - with an application to Cameroon - to estimate two new indicators, the time between seroconversion and ART initiation and the delay between the theoretical time of ART eligibility and the effective time of ART initiation. A second back-calculation model more adapted to Africa countries is developed from data on PLHIV initiating ART - with an application in Cameroon - to estimate the incidence of HIV infection. This thesis proposes original methods to estimate the incidence of HIV infection and the time to HIV diagnosis or ART initiation.

Relation entre l’éducation des parents et la mortalité des enfants au Bénin

Sossa, Fortuné 09 1900 (has links)
Depuis plusieurs décennies, la réflexion sur le lien entre l'éducation des parents, en particulier celle de la mère sur la mortalité des enfants est demeurée une priorité de recherche et un enjeu majeur pour les organisations internationales et les décideurs politiques des pays en développement, confrontés à une mortalité plus élevée et un niveau d’éducation plus faible que dans les pays à revenu élevé. Toutefois, en dépit des arguments théoriques qui justifient l’importance de l’éducation de la mère sur la mortalité des enfants, bon nombre de travaux empiriques menés dans les pays en développement, et surtout ceux de l'Afrique subsaharienne, ont révélé une relation mitigée, indiquant parfois une atténuation ou une absence de relation. Les raisons avancées pour expliquer la divergence des résultats observés ont généralement trait aux différents contextes dans lesquels les études ont été réalisées et aux problèmes surtout d’ordre méthodologique et conceptuel résultant des données disponibles. En utilisant les données des Enquêtes Démographiques et de Santé (EDS) du Bénin, l'objectif principal de cette thèse était d’aboutir à une meilleure compréhension des aspects méthodologiques et conceptuels relatifs à l’association entre l’éducation des parents et la mortalité des enfants. Trois objectifs spécifiques sont examinés. Le premier objectif spécifique est consacré à la relation entre l’éducation de la mère et la mortalité des enfants de moins de cinq ans en 1991-1996 et 2001-2006 pour cerner d'une part, les différences de mortalité des enfants selon les catégories d'éducation de la mère à chacune des périodes et, d'autre part, la variation du risque de mortalité des enfants selon l'éducation de la mère entre ces deux périodes, considérant la baisse de mortalité des enfants qu'a connue le Bénin. Le deuxième objectif spécifique vise à cerner l'impact du niveau moyen de l’éducation des femmes de la communauté sur la mortalité des enfants. Dans le troisième objectif spécifique, nous évaluons dans quelle mesure l'éducation du père (variable souvent omise dans les études antérieures) contribue à l'amélioration de la survie des enfants. Les résultats de nos analyses sont présentés sous forme d’articles scientifiques. À l'aide des analyses multi-niveaux en temps discret, les résultats de l'article 1 montrent que le risque de mortalité des enfants de mères non éduquées n'est pas significativement différent de celui des enfants de mères qui n'ont pas complété le cycle primaire (1 à 5 ans de scolarité). Ce résultat a été observé aussi bien à l’EDS de 1996 qu'à celle de 2006. Le risque de mortalité des enfants de mères qui ont complété au moins le cycle primaire (6 années de scolarité et plus) est plutôt faible comparativement à celui des enfants de mères non éduquées. Les résultats montrent également que le différentiel du risque de mortalité des enfants de moins de cinq ans selon l'éducation de la mère n'a pas significativement changé entre les deux périodes d'enquêtes (1991-1996 et 2001-2006) au Bénin. S'agissant de l’impact du niveau moyen d’éducation des femmes de la communauté sur la mortalité des enfants (article 2), nos résultats confirment que le risque de mortalité des enfants de moins de cinq ans est moins élevé dans les communautés où la proportion de femmes éduquées est plus élevée, et ce, indépendamment de l'éducation de la mère. Plus intéressant, l'effet de l'éducation communautaire sur la mortalité des enfants de moins de cinq ans était plus important dans les communautés où l'offre de soins de santé est disponible et accessible. Quant à l'influence de l'éducation du père (variable souvent omise dans les précédentes études) (article 3), il ressort que le fait d'avoir un père éduqué réduit significativement le risque de mortalité des enfants. Par contre, son effet s'est révélé significatif seulement dans les communautés où l'offre de soins de santé est disponible et accessible. / The possible impact of parental education (especially that of the mother) on child mortality remains an important issue for researchers and a priority for international organizations and policy makers in developing countries, which face relatively higher mortality and lower levels of education. However, despite the theoretical arguments that justify the importance of mother's education for child mortality, many studies in developing countries, especially in sub-Saharan Africa, have revealed an ambiguous relationship, indicating sometimes an attenuation or lack of relationship. The lack of conclusive evidence is generally related to different contexts in which the studies were conducted and to methodological and conceptual problems resulting from the data used. Using DHS data from Benin, the main objective of this thesis is to contribute to a better understanding of the association between parental education and the under-five mortality. Specifically, this study examines: 1) the levels of child mortality by mother's education, focusing on differences between children born to women with no versus incomplete primary schooling (1-5 years of schooling) and changes in the estimated effects of mothers’ schooling across two time periods (1991-1996 and 2001-2006); 2) the extent to which education of women in the community influences the under-five mortality, and finally, 3) the impact of fathers’ schooling on under-five mortality. Using multilevel discrete-time logit models, we show in the first article that mothers with more than 5 years of schooling experience lower under-five mortality risk than mothers with no education. However, no significant difference in the under-five mortality risk between mothers with no education and those with incomplete primary education (1-5 years of schooling) is found for either of the two surveys. Furthermore, estimated effect of mothers’ schooling on under-five mortality did not change significantly between 1991-1996 to 2001-2006. In the second article, our results confirm that residing in a community where more women aged 15-49 have over 5 years of schooling is independently associated with lower under-five mortality. Interestingly, the impact of women's education in the community was more pronounced in areas with higher average child immunization rates. This suggests that the availability and accessibility of health services in the community is a possible mechanism through which the women's community-level education influences child survival. In the third article, we found that father's education is positively associated with the child survival, an effect that is attenuated when after controlling for the supply of health care services accessible in the community.

Understanding Peer Support Work Role Implementation, Work-Life Boundary Navigation and Technological Boundary Transcendence in a Virtual Space

Mirbahaeddin, Elmira 13 February 2024 (has links)
As mental health care increasingly embraces recovery principles, the role of peer support workers (PSWs) has gained recognition. The work that mental health PSWs do became particularly important during the COVID-19 pandemic, when increased needs for mental health care became apparent but were often unmet. This article-based doctoral thesis adopts an interdisciplinary perspective that combines research on management and organization with research on health care and systems. The thesis examines the mental health peer support role and its integration within teams, organizations and health systems. It also considers the peer support role as it was enacted in a virtual space, which became a requirement due to pandemic work-from-home mandates. Within the context of the virtual space, PSWs confronted work-life boundaries that they had to navigate as they enacted their work roles. The virtual space also presented technological and social challenges to and opportunities for peer support, which are examined in this thesis from the points of views of PSWs and peers. Overall, this thesis attends to the PSW role more generally, and to peer support work in the specific context of a virtual environment. The thesis is composed of three studies, the second and third of which had to be adapted to the unexpected challenges and opportunities posed by the COVID-19 pandemic. Study 1 (presented in Chapter 2) is a narrative review that synthesizes the literature on factors influencing formal PSW role implementation in mental health systems. The findings are synthesized in a multilevel framework consisting of macro, meso and micro level influences. The analysis reveals that macro-level influences on PSW role implementation include socio-cultural, regulatory, political and economic factors, most of which act as obstacles. At the meso level, organizational culture, leadership, and human resource management policies play a significant role. Micro-level influences center around PSWs' relationships with team members. Interlevel interactions are also discussed. This study is co-authored with Professor Samia Chreim and was published in Administration and Policy in Mental Health and Mental Health Services in February 2022. For Studies 2 and 3, qualitative data were collected from members of a peer support organization situated in Ottawa. This organization is a publicly funded, not-for-profit organization that provides services free of charge to people experiencing mental health and addictions challenges. Due to the pandemic, all services and operations of this organization transitioned to remote services involving virtual platforms. Study 2 (presented in Chapter 3) is a qualitative case study that delves into the work-life boundary challenges and management of PSWs who were providing virtual mental health support during the pandemic. The study identifies temporal, physical, and task-related boundary challenges in work-life domains. Strategies employed by PSWs to manage these boundaries include segmenting and integrating work and personal domains. The study highlights the importance of self-care and the need for training on work-life boundary management for mental health workers. This research is co-authored with Professor Samia Chreim and is published in BMC Public Health. Study 3 (presented in Chapter 4) focuses on the transition from in-person to virtual mental health peer support services. Through semi-structured interviews with PSWs and service users (or peers), the research examines how technological factors act as bridges and boundaries to mental health peer support services, and whether and how a sense of community can be built or maintained among PSWs and peers in a virtual space when connections are mediated by technology. The findings highlight the mental health peer support needs that were (un)met through virtual services, the technology-based boundaries that were manifested and the steps taken to remove some of these boundaries, and the strategies employed by the organization and its members to establish and maintain a sense of community in a virtual environment marked by physical distancing and technology-mediated interrelations. The manuscript pertaining to this study is co-authored with Professor Samia Chreim and will be submitted soon to an academic journal. Overall, this thesis presents a unique and multi-faceted exploration of the implementation of peer support worker roles in mental health systems and their adaptation to virtual environments. It makes a number of contributions. The multilevel framework developed in Study 1 not only advances knowledge in the field but also offers a structured approach for policymakers and organizations to enhance the formal incorporation of PSW roles into mental health systems. Study 2 provides valuable insights into the nature of work-life boundaries in a virtual space, an important topic at a time when peer support workers and organizations are considering whether and how to maintain some form of virtual work post-pandemic. Study 3 adds to knowledge by highlighting the significance of virtual peer support beyond pandemic conditions. It also enhances understanding of the need for technological adaptation in mental health services and for community building regardless of the model of service. Limitations and implications for research, practice and policy are addressed.

ISSUES REGARDING COMPLEX COMMUNITY-BASED CARDIOVASCULAR HEALTH INTERVENTIONS

Angeles, Ricardo N. 04 1900 (has links)
<p>The thesis presents three papers discussing some of the methodological issues regarding studies investigating complex community-based cardiovascular health interventions. All three studies involved the Cardiovascular Health Awareness Program (CHAP), a standardised blood pressure and risk factor assessment and educational sessions held in pharmacies or other locally accessible areas in small to mid-sized communities in Ontario, Canada.</p> <p>The first paper reviews the literature and proposes a guide on how to develop a theoretical framework for complex community-based interventions using CHAP as an example. The paper describes a stepwise process of developing a theoretical framework including challenges encountered and strategies employed to overcome them.</p> <p>The second paper presents how recently published randomized controlled trials evaluating complex community-based cardiovascular health interventions monitored and reported implementation fidelity based on a structured review of the published articles and a survey of their primary authors. The results showed that fidelity reporting of included studies was better than those described in previous reviews. Fidelity was verified through self-reports by implementers and supervision by researchers. Strategies described to standardize intervention delivery were through training of implementers and use of implementation guides. The authors’ survey results were consistent with the review results though there were some gaps which could be improved to strengthen fidelity reporting.</p> <p>A data analysis issue with studies investigating complex community-based interventions is that outcomes can be affected by factors from multiple levels. The third paper explores the association of individual, partnership, and community-related factors with CHAP participants’ use of health-related community resources and cardiovascular risk behaviours. This was a cross-sectional analysis of an on-going cohort study. The results showed that individual factors (age and self-efficacy) had the most consistent association with the outcomes. Community and partnership level variables showed less consistent association with the outcome. Methodological and analytical challenges were presented.</p> / Doctor of Philosophy (PhD)

Des soins de qualité pour la dépression en première ligne : une contribution à l’amélioration de l’état de santé de la population québécoise

Duhoux, Arnaud 04 1900 (has links)
Contexte De nombreuses études, utilisant des indicateurs de qualité variés, ont démontré que la qualité des soins pour la dépression n’est pas optimale en première ligne. Peu de ces études ont examiné les facteurs associés à la réception d’un traitement adéquat, en particulier en tenant compte simultanément des caractéristiques individuelles et organisationnelles. L'association entre un traitement adéquat pour un épisode dépressif majeur (EDM) et une amélioration des symptômes dépressifs n'est pas bien établie dans des conditions non-expérimentales. Les objectifs de cette étude étaient de : 1) réaliser une revue systématique des indicateurs mesurant la qualité du traitement de la dépression en première ligne ; 2) estimer la proportion de patients souffrant d’EDM qui reçoivent un traitement adéquat (selon les guides de pratique clinique) en première ligne ; 3) examiner les caractéristiques individuelles et organisationnelles associées à l’adéquation du traitement pour la dépression ; 4) examiner l'association entre un traitement minimalement adéquat au cours des 12 mois précédents et l'évolution des symptômes dépressifs à 6 et 12 mois. Méthodes La littérature sur la qualité du traitement de la dépression a été examinée en utilisant un ensemble de mots-clés (« depression », « depressive disorder », « quality », « treatment », « indicator », « adequacy », « adherence », « concordance », « clinical guideline » et « guideline ») et « 360search », un moteur de recherche fédérée. Les données proviennent d'une étude de cohorte incluant 915 adultes consultant un médecin généraliste, quel que soit le motif de consultation, répondant aux critères du DSM-IV pour l’EDM dans la dernière année, nichés dans 65 cliniques de première ligne au Québec, Canada. Des analyses multiniveaux ont été réalisées. Résultats Bien que majoritairement développés à partir de guides de pratique clinique, une grande variété d'indicateurs a été observée dans la revue systématique de littérature. La plupart des études retenues ont utilisé des indicateurs de qualité rudimentaires, surtout pour la psychothérapie. Les méthodes utilisées étaient très variées, limitant la comparabilité des résultats. Toutefois, quelque soit la méthode choisie, la plupart des études ont révélé qu’une grande proportion des personnes souffrant de dépression n’ont pas reçu de traitement minimalement adéquat en première ligne. Dans notre échantillon, l’adéquation était élevée (> 75 %) pour un tiers des indicateurs de qualité mesurés, mais était faible (< 60 %) pour près de la moitié des mesures. Un peu plus de la moitié de l'échantillon (52,2 %) a reçu au moins un traitement minimalement adéquat pour la dépression. Au niveau individuel, les jeunes adultes (18-24 ans) et les personnes de plus de 65 ans avaient une probabilité moins élevée de recevoir un traitement minimalement adéquat. Cette probabilité était plus élevée pour ceux qui ont un médecin de famille, une assurance complémentaire, un trouble anxieux comorbide et une dépression plus sévère. Au niveau des cliniques, la disponibilité de la psychothérapie sur place, l'utilisation d'algorithmes de traitement, et le mode de rémunération perçu comme adéquat étaient associés à plus de traitement adéquat. Les résultats ont également montré que 1) la réception d'au moins un traitement minimalement adéquat pour la dépression était associée à une plus grande amélioration des symptômes dépressifs à 6 et à 12 mois; 2) la pharmacothérapie adéquate et la psychothérapie adéquate étaient toutes deux associées à de plus grandes améliorations dans les symptômes dépressifs, et 3) l'association entre un traitement adéquat et l'amélioration des symptômes dépressifs varie en fonction de la sévérité des symptômes au moment de l'inclusion dans la cohorte, un niveau de symptômes plus élevé étant associé à une amélioration plus importante à 6 et à 12 mois. Conclusions Nos résultats suggèrent que des interventions sont nécessaires pour améliorer la qualité du traitement de la dépression en première ligne. Ces interventions devraient cibler des populations spécifiques (les jeunes adultes et les personnes âgées), améliorer l'accessibilité à la psychothérapie et à un médecin de famille, et soutenir les médecins de première ligne dans leur pratique clinique avec des patients souffrant de dépression de différentes façons, telles que le développement des connaissances pour traiter la dépression et l'adaptation du mode de rémunération. Cette étude montre également que le traitement adéquat de la dépression en première ligne est associé à une amélioration des symptômes dépressifs dans des conditions non-expérimentales. / Background Numerous studies, using a variety of quality indicators, highlight an important gap in the quality of care for depression in primary care. Few of these studies examined factors associated with receiving adequate treatment, particularly with a simultaneous consideration of individual and organizational characteristics. The association between adequate treatment for a Major Depressive Episode (MDE) and improvements in depressive symptoms is not well established in naturalistic practice conditions. The objectives of this study were to i) systematically review indicators used to measure the quality of depression treatment in primary care, ii) estimate the proportion of primary care patients with a MDE who receive adequate treatment, iii) examine the individual and organizational characteristics associated with the receipt of minimally adequate treatment for depression, iv) examine the association between receiving minimally adequate treatment for MDE (i.e. according to clinical guidelines) in the previous 12 months and evolution of depressive symptoms at 6 and 12 months. Methods The literature on the quality of depression treatment was reviewed using a set of keywords (depression, depressive disorder, quality, treatment, indicator, adequacy, adherence, concordance, clinical guideline and guideline) and « 360search », a federated search engine. Data were obtained from a cohort study including 915 adults consulting a general practitioner (GP), regardless of the motive of consultation, meeting DSM-IV criteria for previous-year MDE, and nested within 65 primary care clinics in Quebec, Canada. Multilevel analyses were conducted. Results Though mostly based on recommendations from clinical practice guidelines, a great variety of indicators were observed. Most studies used rudimentary indicators to measure the quality of depression treatment, especially for psychotherapy. Studies also differed greatly with respect to the methods used, thus limiting the comparability of results. However, whatever the chosen method, most studies reveal that a large proportion of people with depression do not receive minimally adequate treatment in primary care settings. In our sample, adherence to guidelines was high (> 75 %) for one third of the quality indicators that were measured but was low (< 60 %) for nearly half of the measures. Just over half of the sample (52.2 %) received at least one minimally adequate treatment for depression. At the individual level, young adults (18-24) et older people (>65) had a lower probability of receiving at least one minimally adequate treatment. This probability was higher for people with a family physician, a supplementary insurance coverage, a comorbid anxiety disorder and a more severe depression. At the clinic level, the availability of psychotherapy on-site, the use of treatment algorithms, and the mode of remuneration perceived as adequate were associated with more adequate treatment. Results also showed that i) receiving at least one minimally adequate treatment for depression was associated with greater improvements in depression symptoms at 6 and at 12 months; ii) adequate pharmacotherapy and adequate psychotherapy were both associated with greater improvements in depression symptoms, and iii) the association between adequate treatment and improvement in depression symptoms varied as a function of severity of symptoms at the time of inclusion in the cohort with worse symptoms at the time of inclusion being associated with greater reductions at 6 and 12 months. Conclusions Our findings suggest that interventions are needed to increase the quality of depression treatment in primary care. These interventions should target specific populations (i.e. the younger adults and the elderly), enhance accessibility to psychotherapy and to a regular family physician, and support primary care physicians in their clinical practice with patients suffering from depression in different ways such as developing knowledge to treat depression and adapting mode of remuneration. This study also shows that adequate treatment for depression is associated with improvements in depressive symptoms in naturalistic primary care practice conditions.

La violence domestique envers les femmes au Mexique : une analyse multidimensionnelle et intersectionnelle

Valle-Fajer, Minea 03 1900 (has links)
En s’inscrivant dans la perspective du féminisme intersectionnelle et en mobilisant des méthodes mixtes, cette recherche tente de mieux comprendre la violence domestique envers les femmes au Mexique, à la fois à travers une analyse du discours des féministes mexicaines et d’une analyse statistique multidimensionnelle de données d’enquête identifiant les facteurs institutionnels, économiques et socioculturels associés au risque de vivre de la violence domestique. Cette thèse se démarque des réflexions féministes traditionnelles faites au Mexique puisqu’elle approche les rapports de genre en lien avec d’autres systèmes d’oppression et de subordination, fondés notamment sur les rapports de classe et l’ethnicité. Ainsi, elle appréhende la violence faite aux femmes en lien avec le patriarcat, sans réduire ce dernier à quelques indicateurs sociodémographiques et comportementaux mesurés au niveau individuel, mais en tenant compte du contexte d’inégalité de genre au niveau régional. Ce faisant, la recherche tente de réconcilier les deux grandes perspectives théoriques qui expliquent la violence conjugale, soit les approches de la violence familiale (qui s’attardent à des facteurs au niveau microsocial) et les approches féministes (qui mettent l’accent sur la structure patriarcale, c’est-à-dire le contexte plus large des inégalités de genre). Les résultats des entretiens réalisés avec des féministes représentant les trois branches du féminisme mexicain (féminisme hégémonique, populaire et autochtone) ont révélé les fractures existantes à l’intérieur du mouvement féministe au Mexique (antagonisme entre l’institutionnalisation et l’autonomie du mouvement féministe). De façon générale, l’analyse des entretiens a montré que l’engagement des féministes envers la cause des femmes est en accord avec les «idéaux types» des trois branches du féminisme mexicain. Les féministes hégémoniques mettent surtout l’accent sur la structure patriarcale de la société mexicaine et sur les inégalités de genre lorsqu’il s’agit de trouver des causes à la violence faite aux femmes. Pour les féministes du secteur populaire, la violence faite aux femmes s’explique autant par les inégalités de genre, que par les effets du système économique capitaliste. Le discours des femmes autochtones semble, quant à lui, tenir davantage compte de l’articulation des rapports de genre, des rapports ethniques, ainsi que des rapports socio-économiques. Néanmoins, nous constatons que les féministes de la branche hégémonique et populaire semblent de plus en plus sensibles à l’entrecroisement de systèmes de domination et d’oppression. Par ailleurs, l’analyse multiniveau effectuée à partir des données de l’Enquête nationale portant sur la dynamique des relations dans les ménages (2006), a révélé plusieurs résultats importants qui méritent d’être soulignés. D’abord on constate que les différences de prévalence des violences entre les municipalités mexicaines sont en grande partie expliquées par leur composition sociale, c’est-à-dire par des caractéristiques des femmes et de leur couple (niveau micro), plutôt que par des différences entre le niveau des inégalités de genre dans les municipalités mexicaines mesurées par l’ISDH (Indice Sexospécifique du Développement Humain). Les résultats des analyses montrent que les femmes autochtones ont en général des taux de violences moins élevés que les femmes métisses (groupe majoritaire). Enfin, en ce qui a trait à la relation entre le contexte d’inégalité de genre et la violence conjugale, les résultats suggèrent que plus l’ISDH d’une municipalité est élevée, plus il y a de femmes qui subissent les formes de violences. Cela va à l’encontre des postulats habituels des théories féministes et suggèrent que les progrès récents de la situation de la femme en matière de santé, d’éducation et de revenu n’ont pas bouleversé les rapports de genre encore très patriarcales qui continuent à privilégier la suprématie des hommes (Casique, 2004). / By adopting the intersectional feminist approach and mobilizing mixed methods, this research seeks to better understand partner violence in Mexico, both through a discourse analysis of the Mexican feminist movement and a quantitative multidimensional level of analysis by identifying the institutional, economic and socio-cultural factors associated with the risk of experiencing domestic violence. This research differs from the traditional feminist reflections made in Mexico because it takes into consideration gender inequality in interaction with other systems of oppression and subordination, mainly based on social class and ethnicity. Thus, it captures partner violence in relation to patriarchy, without reducing it to sociodemographic and behavioral indicators measured at the individual level, but by taking into account the structural context of gender inequality at the regional level. By integrating individual and contextual factors, this research attempts to reconcile the two major theoretical perspectives that explain partner violence, which are the family violence approach (that linger to factors at the micro level) and feminist approaches (which focus on the patriarchal structure, in other terms the broader context of gender inequality). The results of the discursive analysis from the interviews with the feminists representing all three branches of the Mexican feminism (hegemonic, popular and indigenous feminism) revealed existing fractures within the feminist movement in Mexico (antagonism between institutionalization and autonomy of the feminist movement). In general, this analysis showed that the feminists’ gender struggle and their demands are consistent with the "ideal types" of the three branches of the Mexican feminism. Hegemonic feminism focuses mainly on the patriarchal structure of Mexican society and gender inequality when it comes to finding the causes of violence against women. For the popular feminism, violence against women is explained by both gender inequalities and the vulnerable economic situation. The discourse of indigenous women emphasizes the articulation of gender, ethnic and socio-economic inequalities. However, we found evidence that hegemonic and popular feminism seem increasingly sensitive to the intersection of systems of domination and oppression. In addition, multilevel analysis using data from the National Survey of Dynamics of Relationships within Households (2006) revealed several important findings that deserve to be highlighted. Firstly, we show that differences in the prevalence of partner violence among Mexican municipalities are largely explained by their social composition, that is to say, by the characteristics of women and their relationship (micro level), rather than differences between the level of gender inequality in the Mexican municipalities measured by the GDI (gender-Human Development Index). In addition, the results show that indigenous women generally have lower rates of violence that the rest of mestizas Mexican women (majority group). Finally, in regard to the relationship between the context of gender inequality and domestic violence, and contrary with what would be expected, violence is higher in municipalities with higher GDI. This result seems to contradict feminist assumptions. It would seem that despite recent progress in women’s situation in areas such as health, education and income in Mexico, it has not been able to transform the gender order.
