Le présent mémoire explore les liens entre les différents types de capitaux (social, familial, délinquant et individuel) et certains actes déviants, soit la consommation de substances psychotropes et l’implication criminelle violente chez un groupe de décrocheurs scolaires canadiens. Dans un premier temps, il s’agit d’établir la prévalence et les habitudes de consommation de cette population aliénée du système éducatif. De plus, cette étude concerne l’implication criminelle violente des décrocheurs. Plus précisément, il s’agit de déterminer la fréquence des manifestations agressives et les types de violence perpétrés par ces jeunes, ainsi que d’examiner les liens qui se tissent entre la consommation de substances psychotropes et la commission d’actes violents. Ensuite, il est question d’étudier l’impact des différents capitaux (social, familial, délinquant et individuel) sur la consommation de substances psychoactives et l’implication criminelle violente des décrocheurs. En outre, dans une perspective davantage clinique, le dernier objectif aura pour but d’identifier différentes typologies de décrocheurs scolaires. Les analyses s’appuient sur un échantillon de 339 jeunes décrocheurs scolaires de Montréal et Toronto. Les informations amassées par rapport à l’usage de substances psychotropes et la commission d’actes violents concernent les douze mois qui ont précédé la passation du questionnaire. Succinctement, les taux de prévalence de consommation des décrocheurs apparaissent plus importants que ceux de la population estudiantine, leur usage est plus inquiétant de même que l’auto-évaluation de leur dépendance. Les résultats révèlent également une implication criminelle violente importante, surtout chez les garçons et les consommateurs de substances psychotropes. Qui plus est, le capital délinquant semble avoir un impact majeur sur l’usage d’alcool et de drogues de même que sur les manifestations de violence perpétrées par les décrocheurs. Enfin, trois typologies de décrocheurs scolaires ont été identifiées, soit les invisibles, les détachés et les rebelles. / This paper explores the links between different types of capital (social, familial, criminal and individual) and some deviant acts, consumption of psychotropic drugs and violent criminal involvement among Canadian school drop-outs. In first place, the prevalence and habits of alcohol and drug consumption of this population alienated from the education system will be established. Moreover, this study concerns violence involvement of school drop-outs. More specifically, in determining the frequency of aggressive events and types of violence perpetrated by these young people, and to examine the relationships between the use of psychotropic substances and the commission of violent acts. Then, there is the impact of various capitals (social, familial, criminal and individual) on the consumption of psychoactive substances and violent criminal involvement of school drop-outs. In a more clinical perspective, the last goal will be to identify different types of school drop-outs. This analysis is based on a sample of 339 young school leavers in Montreal and Toronto. The information collected in relation to the use of psychotropic substances and the commission of violent acts involve the twelve months preceding the award of the questionnaire. Briefly, the prevalence of consumption of drop-outs is more important than the student population; their use is even more disturbing as well as the self-assessment of their dependency. The results also show a significant violent criminal involvement, especially among boys and consumers of psychotropic substances. Moreover, the criminal capital appears to have a major impact on the use of alcohol and drugs as well as the manifestations of violence perpetrated by drop-outs. Finally, three types of school dropouts have been identified: the invisible, the detached and the rebels.

Cette thèse vise un apport conceptuel et empirique au sujet du rapport à l’alcool chez les hommes et les femmes âgés de 55 ans et plus provenant de la population générale du Canada. Les deux objectifs généraux sont de mieux comprendre l’influence du contexte social/environnemental sur la consommation d’alcool des adultes âgés et de mieux comprendre la relation entre la consommation d’alcool et la santé. La thèse est composée de deux articles empiriques associés à chacun des objectifs. Plus précisément, le premier article tente d’évaluer l’impact des changements associés à l’alcool depuis les années 1990 dans le contexte canadien sur la consommation d’alcool (effet période) en comparant des adultes âgés de 55 à 74 ans provenant de deux enquêtes populationnelles canadiennes : CADS de 1994 (Canada’s Alcohol and other Drugs Survey) et GENACIS de 2004 (GENder, Alcohol, and Culture: an International Study). Il vérifie également si le contexte a un effet significatif sur les différences observées en tenant compte de l’âge, de la perception subjective de la santé et de la composition sociodémographique des échantillons. Les résultats montrent que les taux de buveurs, de consommation excessive, de buveurs de bière et de vin sont plus élevés en 2004, dans un contexte social/environnemental plus favorable à l’alcool. De plus, les profils de consommation d’alcool ne diffèrent pas entre 1994 et 2004 (volume, fréquence, quantité, quantité maximale), signifiant probablement l’influence des changements physiques qui accompagnent le vieillissement normal sur la modulation de la consommation d’alcool avec l’âge. Le deuxième article vise à dégager une typologie de buveurs et de non-buveurs chez les adultes âgés canadiens, à évaluer comment cette typologie est associée à l’état de santé ainsi qu’à comparer le rôle de l’alcool à celui d’un ensemble d’autres déterminants de la santé dans l’association à la santé (ici santé autoperçue). Les résultats issus de l’enquête GENACIS de 2004 montrent que les buveurs se perçoivent en meilleure santé que les non-buveurs, peu importe le profil de consommation d’alcool rapporté. Il est probable que l’état de santé autoperçue dicte le statut de buveur ou de non-buveur et non pas l’inverse. Les résultats montrent aussi que les caractéristiques démographiques, psychosociales et les comportements liés à la santé des adultes âgés sont davantage associés à la perception de leur santé que leur consommation (ou non-consommation) d’alcool seule. Les résultats de ce second article indiquent notamment que les bienfaits de la consommation d’alcool se définissent probablement par la biologie, mais pas seulement par la biologie. Il est recommandé de poursuivre l’étude du rapport à l’alcool chez les adultes âgés qui peut varier d’une cohorte et d’une période à l’autre. D’un point de vue de santé publique, la conceptualisation d’un modèle de santé qui cible les adultes âgés implique une meilleure compréhension de l’impact de la consommation d’alcool et d’autres déterminants de la santé sur l’état de santé. Les contributions et implications pratiques de la thèse ainsi que les principales limites et pistes de futures recherches sont présentées dans la discussion. / The aim of the thesis is to contribute to a better conceptual and empirical understanding of alcohol consumption among men and women aged 55 years and older from the general Canadian population. The two general objectives pursued are to gain a better understanding of the potential influence of the social/environmental context on drinking habits among older adults and to achieve a clearer discernment of the relation between alcohol consumption and health. The thesis comprises two empirical articles relating to each respective objective. More specifically, the first article verified whether contextual changes associated to alcohol and unique to the decade spanning the 1990s may have had an impact on alcohol consumption (period effect) by comparing two subsamples of older adults from two Canadian surveys: the 1994 CADS (Canada’s Alcohol and other Drugs Survey) and 2004 GENACIS (GENder, Alcohol, and Culture: an International Study). The article also assessed if the context had a significant effect on the differences observed when age, subjective perception of health and the sociodemographic composition of the samples were taken into consideration. Results first show that, in a social/environmental context that is more favourable to drinking in general, the rates of current drinkers, binge drinking, beer and wine drinkers are significantly higher in 2004. In addition, drinking profiles were not significantly different between 1994 and 2004 (volume, frequency, quantity, maximum quantity), pointing at the potential impact of normal physiological changes due to aging on drinking profiles. The second article aimed to build a drinking typology (including drinkers and non-drinkers) among older Canadian adults, to assess how the drinking typology was related to health status and to compare the role of alcohol with other determinants of health (demographic, psychosocial and health-related factors) in explaining health status. To do so, the subjective perception of health (subjective health) was used as a proxy for actual health status. Results from the 2004 GENACIS survey indicated that drinkers perceived themselves as being in better physical health than nondrinkers, regardless of the drinking pattern. Health status may explain drinking status and not the opposite. Results also showed that the demographic, psychosocial and health-related characteristics of older adults contributed significantly more to the variation in subjective health than the drinking status alone. Health benefits of drinking are explained by biological factors, but not exclusively by biological factors. In conclusion, alcohol research needs to emphasize the study of drinking among older adults, which can vary depending on the cohort and period under study. From a public health perspective, health-predicting models focusing on older adults need to be built on a better understanding of the impact of alcohol and other determinants of health on health status. Main contributions, practical implications, limitations of the thesis and recommendations for future research are presented in the discussion.

Introdução: A hipertensão arterial é de causa multifatorial, envolvendo hábitos de vida e estilos de vida inadequados como o consumo excessivo de bebida alcoólica que propiciam a elevação dos níveis pressóricos. Além disso, os sintomas relacionados ao transtorno mental comum também podem se associar ao estado de saúde, provocando mais danos ao sujeito com hipertensão arterial. Diante disso, o presente estudo teve como objetivo principal identificar associação entre a ocorrência de hipertensão arterial com o consumo de bebidas alcoólicas e a presença de transtorno mental comum em indígenas das aldeias Muras, residentes em região rural e urbana. Casuística e Métodos: Estudo transversal, de base populacional, com 455 indígenas Mura residentes no município de Autazes, Amazonas, Brasil. Foi aplicada a entrevista semi-estruturada com questões referentes aos dados socioeconômicos e educacionais, hábitos de vida, história clínica, histórico familiar, além dos questionários Alcohol Use Disorders Identification Test (AUDIT) e Self-Reporting Questonnaire (SRQ-20), para avaliar o consumo de álcool e presença de transtorno mental, respectivamente. A pressão arterial foi medida com aparelho automático de braço validado. Foram realizadas três medidas e usada a média das duas últimas medidas. Realizaram-se ainda, medida do peso, altura, circunferência do pescoço, circunferência da cintura, avaliação de bioimpedância; glicemia, triglicérides e colesterol com medida capilar. Na análise bivariada, foi testada a associação entre hipertensos, separadamente, com os dois desfechos: consumo de bebidas alcoólicas e a presença de transtorno mental comum explorando especialmente, os aspectos relacionados à hipertensão arterial. Foi ajustada a regressão de Poisson com variância robusta, para ambos os desfechos, com modelagem em stepwise backward automatizado, tendo como critério de entrada, p<0,20 e de significância no modelo final, p0,05. Utilizou-se como estimativa, as razões de prevalência e respectivos intervalos de confiança de 95%. Resultados: A maioria dos participantes era do sexo feminino (57,8%), com 42,10 (16,74) anos, vivendo com companheiro (74,7%) e cerca de quatro filhos por família, baixo nível de escolaridade Analfabeto/Fundamental incompleto (41,1%) e renda até dois salários mínimos (85,0%). A prevalência de hipertensão arterial foi de 26,6%, tabagismo (20,4%) e ser sedentário/irregularmente ativo (52,8%). O consumo de bebida alcoólica foi de 40,2%, sendo 13,4% classificados como alto risco para dependência alcoólica, e maior na área rural em comparação à urbana (57,3% vs 22,2%) p<0,001. Destacam-se os seguintes aspectos do uso abusivo de álcool: sentimento de culpa/remorso (45,9%); amnésia repentina por não lembrar o ocorrido na noite em que bebeu (31,7%); além de machucar-se ou sentir-se prejudicado por causa da bebida (29,6%); preocupação por parte de parentes, amigos ou profissionais de saúde, que aconselharam o entrevistado a interromper o consumo (51,5%). Não houve associação entre a presença e consumo de bebida alcoólica (23% e 26%). Os indígenas com diagnóstico de hipertensão referida, faziam menos uso de bebida alcoólica (14,2%vs 85,8%, p=0,009), porém nas ocasiões em que bebiam, ingeriam maior quantidade, comparado com os que não referiram hipertensão [55,3(72,2) vs 33,3(62,2) gramas de Etanol p=0,008]. A prevalência de transtorno mental comum foi de 45,7%, com destaque para os seguintes itens: referência de dores de cabeça frequentes (69,5%), sentir-se nervoso, tenso ou preocupado (66,2%), ter se sentido triste ultimamente (56,0%), dormir mal (55,2%) e ter sensações desagradáveis no estômago (42,9%). Além disso, destaca-se que 7,3% referiram ideia de acabar com a própria vida e 4,2% sentiram-se incapazes de desempenhar papel útil. Após análise ajustada a razão de prevalência após análise ajustada (Razão de prevalência, IC-95%), verificou-se associação positiva entre ingestão de bebida alcoólica e sexo masculino (2,72, IC-2,12-3,48), tabagismo (1,29, IC-1,06-1,56) e morar na zona rural (2,09, IC-1,61-2,72). Porém, a ação foi protetora para idade (0,98, IC-0,98-0,99), consumo de alimentos in natura (0,97, IC-0,95-0,99), e ausência de dislipidemias (0,75, IC-0,62-0,9). Entre os que apresentaram transtorno mental comum, a hipertensão arterial identificada esteve presente em 30,3% e o consumo de álcool uma vez ao mês em 22,1%. Após a análise ajustada (Razão de prevalência, IC-95%) verificou-se associação positiva entre o transtorno mental comum e a zona de moradia urbana (1.25, IC-1,02-1,54), não sabia que tinham antecedentes para diabetes (1.56, IC-1,24-1,96) e a ingestão de bebida alcoólica (1.01, IC-1,00-1,02). Porém, foi ação protetora não ter antecedentes pessoais de cardiopatia (0.59, IC-0,48-0,73). Conclusão: Observou-se que a presença de hipertensão arterial, consumo de bebida alcoólica e de transtorno mental comum foram elevados nos indígenas da etnia Mura. Esses achados podem ser decorrentes da aproximação e convivência entre indígenas e não indígenas favorecendo mudanças culturais, especialmente de hábitos e estilos de vida, com aumento do risco de doenças crônicas não transmissíveis. / Background: The arterial hypertension has a multifactorial disorder, including unappropriated habits and lifestyle as the excessive consumption of alcoholic beverages that may increase the blood pressure. Additionally, the symptoms related to the common mental disorder may be also associated with the health status, producing even more damages to the hypertensive subjects. Thus, this study aimed to identify the association of arterial hypertension occurrence with alcoholic beverages consumption and presence of common mental disorder in Indigenous from Mura villages, who live in rural and urban zones. Casuistic and Methods: Its a cross-sectional investigation, with demographic base, conducted with 455 Mura Indigenous from Autazes, Amazon, Brazil. Through a semi-structured interview, we gathered data about sociodemographic and educational profile, lifestyle, clinical records, family antecedents. In this occasion, the Alcohol Use Disorders Identification Test (AUDIT) and the Self-Reporting Questionnaire (SRQ-20) were applied to assess respectively the alcohol consumption and the presence of common mental disorder. The blood pressure was measured with an arm automatic device, validated for this goal, being three measures taken and, from the two last of them, a mean was obtained. Furthermore, we gathered weight, height, neck circumference, waist circumference, bioimpedance, glycemia, triglycerides and cholesterol, capillary measure for the last ones. In the bivariate analysis, we analyzed the association between hypertensive persons and the both outcomes- the alcohol consumption and the presence of common mental disorder, emphasizing the issues hypertension-related issues. The Poison regression, with robust variance, was adjusted for both outcomes, with a modelling in automatized stepwise backward, being p<0,20 the entrance criteria and p<0,05 the significance level for the final model. As estimative, we used the odds ratios and their respective confidence intervals of 95%. Results: Most were females (57,8%), with mean age of 42,2(16,74) years, living with a partner (74,7%), with about four children per family, poor educational level- Illiterate/Incomplete Basic (41,1%) and income of up two minimum wages (85,0%). 26,6% of the sample had hypertension, 20,4% were smokers and 52,8% were sedentary/irregularly active. Alcohol consumption was of 40,2%, with 13,4% showed high risk for alcohol addiction, and the consumption was higher in rural area in comparison with the urban one (57,3% vs 22,2%) p<0,001. We emphasize the following aspects of alcohol abuse: feeling of guilty and remorse (45,9%); abrupt amnesia for not remembering what happened in the night that they had drunk (31,7%); feeling hurt or impaired due to the drink consumption (29,6%); concerns from relatives, friends or healthcare professionals who advised the interviewed to interrupt the consumption (51,5%). There was not association between presence and alcoholic beverages consumption (23% and 26%). Indigenous diagnosed with referred arterial hypertension drank less alcoholic beverages (14,2%vs 85,8% p=0,009), but, when they drank, they had a larger amount than those with referred hypertension [55,3(72,2) vs 33,3(62,2) grams of Ethanol p=0,008]. The common mental disorder was identified in 45,7% of the individuals, being highlighted the following items: reporting of frequent headaches (69,5%), feeling nervous, anxious or worried (66,2%), feeling sad in the last days (56,0%), sleeping badly (55,2%) and having upset stomach (42,9%). Additionally, 7.3% reported the idea of committing suicide, and 4,2% felt themselves unable to play a useful role. We verified positive association between alcoholic beverage consumption and male gender (2.72, CI-2,12-3,48); smoking (1.29, CI-1.06-1.56); and living in rural area (2.09, CI-1.61-2.72). However, the action was protective for the age (0.98, CI-0,98-0,99), intake of natural foods (0.97, CI-0,95-0,99), and absence of dyslipidemias (0.75, CI-0,62-0,9). Among those diagnosed with common mental disorder, the arterial hypertension was found in 30,3% and the alcohol consumption once a month in 22,1%. We observed a positive association of common mental disorder and: living in the urban area (1.25, CI-1,02-1,54); unknowing the antecedents for diabetes (1.56, CI-1,24-1,96); and the alcohol consumption (1.01,CI-1,00-1,02). However, the absence of personal background of heart diseases was not protective (0.59, CI-0,48-0,73). Conclusion: We observed that the presence of arterial hypertension, alcoholic beverages consumption and common mental disorder were high in the Mura ethnicity. This finding may be explained for the approach and interaction among Indigenous and non-Indigenous, which favors cultural changes, especially in habits and lifestyle, increasing the risk of non-transferable chronic diseases.

Syftet med vårt arbete är att undersöka hur hemtjänstpersonal ser på problematisk alkoholkonsumtion i förhållande till självbestämmande bland äldre samt om det kan ha betydelse för deras omsorg av den äldre. Kvalitativa halvstrukturerade intervjuer genomfördes med hemtjänstpersonal (n=4) som analyserades hermeneutiskt utifrån teorier om makt och handlingsutrymme. Av resultaten framgår att självbestämmanderätten som Socialstyrelsen beskrivit den, är villkorad i hemtjänstpersonalens tolkning och att det saknas tydliga riktlinjer och rutiner i hemtjänstens arbete med äldre som har en problematisk alkoholkonsumtion. Resultaten visar att hemtjänstpersonalen gör individuella bedömningar i arbetet med äldre som har en problematisk alkoholkonsumtion. Det framgår att hemtjänstpersonalens arbete är förenat med svåra etiska ställningstaganden, där även maktförhållanden synliggörs och där hemtjänstpersonalen har tolkningsföreträde i förhållande till den äldre och förmynderi är en potentiell riskfaktor. En slutsats är att tydligare riktlinjer angående inköp av alkohol till äldre med en problematisk alkoholkonsumtion kan tänkas bidra till att hemtjänstpersonalen arbetar på ett mer likformigt sätt vilket i sin tur ökar rättssäkerheten för den äldre. / The aim of our study was to examine how integrity and self-determination is conceived by care assistants regarding older care takers with a problematic alcohol consumption, and if it affects their care provided. Qualitative semi-structured interviews, carried out with home care assistants (n=4) and analyzed hermeneutically with theories of power and discretion, showed that self-determination, as described by The Swedish National Board of Health and Welfare, is fulfilled only under certain conditions in the home care assistant’s interpretation. We also found a lack of guidelines and routines concerning problematic alcohol consumption among older care takers. Our results showed that home care assistants made individual assessments in their work with older care takers with problematic alcohol consumption actualizing a difficult ethical dilemma between neglect and paternalism. These ethical issues visualize power relationships where home care assistants have the prerogative to decide in relation to the care takers, where paternalism is a potential risk factor. Clear guidelines regarding the purchase of alcohol to older care takers with problematic alcohol consumption may contribute to home care assistants working more uniformly which leads to a higher state of legal security for the care takers.

Ce travail est principalement axé sur la modélisation par approche de groupe de trajectoires développementales de la consommation d'alcool des adolescents au Quebec. / Contexte: L’impulsion à cette étude est le fait que la consommation d'alcool chez les adolescents a augmenté au cours des dernières années et que la consommation excessive d'alcool épisodique est de plus en plus fréquente chez les jeunes adultes. La prévention des problèmes de la consommation d’alcool chez les jeunes doit commencer par l'identification appropriée des sous-groupes d'adolescents à risque élevé. Objectifs: Cette étude avait trois objectifs: (i) identifier les trajectoires de développement de la consommation d'alcool chez les adolescents; (ii) d'examiner l'influence du sexe sur les trajectoires et (iii) d'examiner la relation entre les trajectoires de consommation d'alcool à l'adolescence et la consommation d'alcool excessive épisodique à l'âge jeune adulte. Méthode: Nous avons utilisé des données de l'étude longitudinale (n = 1294, 1999 - 2012) des adolescents âgés de 12 à 13 ans au début de l'étude de NDIT (Dépendance de la nicotine chez les adolescents). Les 1245 participants qui ont complété au moins trois des 22 cycles de NDIT ont été stratifiés selon leur statut alcoolique. C’est à dire ceux qui avaient consommé de l'alcool au début de l’étude, les buveurs (n = 497) et ceux qui n'avaient jamais consommé d'alcool au début de l’étude, les abstinents (n=748). Nous avons identifié les trajectoires de développement de la fréquence de la consommation d'alcool sur la base de 19 vagues de collecte de données après le début de l’étude de la 7e année (de 12 à 13 ans) à la 11e année (17-18 ans) en utilisant la modélisation semi-paramétrique basée sur l’approche des trajectoires par groupe (GBTM). Nous avons conduit des séries de régression logistique afin d'étudier l'association entre les trajectoires de développement de la consommation d'alcool et la consommation excessive épisodique à l'âge jeune adulte chez les buveurs d’alcool au début de l’étude et les abstinents au début de l’étude. Résultats: Pour l’ensemble de l’échantillon global (abstinents et buveurs) cinq groupes de trajectoires ont été identifiés. Ensuite, quatre groupes de trajectoires ont été identifiés parmi les abstinents au début de l’étude (‘faible’ consommateurs (28.3%, n=215), consommateurs tardifs croissants (21.5%, n=161), consommateurs modérés (29.9%, n=224) et consommateurs réguliers (20.3%, n=152). Parmi les consommateurs d’alcool (buveurs) au début de l’étude, les groupes de trajectoires comprenaient des consommateurs d’alcool peu fréquents (rares) (15.4%, n=76), des consommateurs en hausse (34.1%, n=170), des consommateurs réguliers (41.7%, n=207) et des consommateurs en baisse (8.8%, n=44). Les adolescents des groupes de trajectoires de fréquence de consommation d’alcool les plus élevées étaient plus susceptibles de pratiquer la consommation d’alcool excessive épisodique à l’âge jeune adulte. Conclusion: Cette étude montre la variabilité des trajectoires de développement de la consommation d'alcool des adolescents. Les données suggèrent que des approches multiples peuvent être nécessaires pour prévenir la consommation problématique d'alcool chez les adolescents et que ces approches devraient être nécessairement adaptées au sexe. / Background: The impetus for this study is that alcohol use among adolescents has increased in recent years and that heavy episodic or binge drinking is increasingly common in young adults. Prevention of problem drinking must begin with appropriate identification of sub-groups of adolescents at higher risk. Objective: This study had three objectives: (i) to identify the developmental trajectories of alcohol consumption among teens; (ii) to examine the influence of sex on trajectories and (iii) to examine the relationship between alcohol consumption trajectories in adolescence and binge drinking in young adulthood. Method: We used data from the NDIT (Nicotine Dependence In Teens) longitudinal study (n=1294; 1999 – 2012) of adolescents ages 12-13 years at inception. The 1245 participants who completed at least three of 22 NDIT cycles were stratified into those who had consumed alcohol at baseline, baseline drinkers (n=497) and those who had never consumed alcohol, baseline nondrinkers (n=748). We identified the developmental trajectories of the frequency of alcohol consumption based on 19 data collection waves after baseline from grade 7 (age 12-13) to grade 11 (age 17-18), using semi-parametric group-based trajectory modeling. Logistic regression was conducted to investigate the association between the alcohol consumption developmental trajectories and binge drinking in young adulthood among baseline drinkers and baseline nondrinkers. Results: Five trajectory were identified for the whole sample (baseline nondrinkers and baseline drinkers, n=1245). Then, four trajectory groups were identified among baseline nondrinkers (low consumers (28.3%, n=211), increasing late consumers (21.5%, n=161), moderate drinkers (29.9%, n=224), and regular users (20.3%, n=152). Among baseline drinkers, trajectory groups included experimenters (15.4%, n=76), increasing (34.1%, n=170), regular (41.7%, n=207) and decreasing consumers (8.8%, n=44). Participants in the higher trajectory groups were more likely to binge drink in young adulthood. Conclusion: This study shows variability among adolescents in alcohol consumption developmental trajectories. The data suggest that multiple approaches may be necessary to prevent problem alcohol consumption among adolescents and that these approaches may need to be sex-sensitive.

Background. Within the South African context there is a large body of research regarding the associations between maternal gestational drinking and diagnosable child FASDs. However, there remains a paucity of local research regarding the impacts of other kinds of maternal drinking behaviours (e.g. past and present maternal drinking) and related socio-demographic factors on developmentally sensitive areas of child neurocognitive functioning, such as executive functioning (EF). Methods. This study was cross-sectional in design, utilising a gender balanced sample of N=464 children between the ages of 9.00 and 15.12 (year.months) in three rural areas within the Western Cape. Information regarding maternal drinking behaviours (before, during and after pregnancy) and related socio-demographic factors was collected via structured interviews with mothers or proxy respondents. Six subtests from the Cambridge Automated Neuropsychological Battery (CANTAB), were used to assess three aspects of child EF namely: (1) processing speed, assessed by the MOT and RTI subtests, (2) attention, assessed by the MTT and RVP subtests and (3) memory, assessed by the SWM and PAL subtests. Findings. For all three maternal alcohol use behaviours examined, there was an apparent non-significant trend whereby children of mothers who reported alcohol use (before, during and after pregnancy) performed worse (on average) than children of mothers reporting non-alcohol use on the EF subtests. Several of the socio-demographic factors were found to act as significant predictors of subtest specific EF performance including child sex (RTI: B=.46, p<. 01; MTT: B=.05, p<.05), child age (RTI: B=.27, p<.05; MTT: B=.11, p<.01), home language (MOT: B=- .13, p<.05), maternal employment (MTT: B=-.04, p<.05) and household size (SWM: B=-1.29, p<.05). Conclusions. These study findings provide initial insights into the impacts of different types of maternal drinking behaviours and related socio-demographic factors on child EF outcomes within the context of an LMIC, South Africa.

Souvent diagnostiqué à un stade avancé, le cancer du pancréas (CP) est un cancer particulièrement létal pour lequel il n’y a, à ce jour, que très peu de possibilités de traitement et de diagnostic anticipé. L’identification de facteurs de risque modifiables pourrait fournir des données épidémiologiques nécessaires au soutien de la mise en place de mesures préventives. Cette thèse a pour but d’étudier l’étiologie du CP en évaluant le rôle de la consommation d’alcool et du mode de vie dans l’étude prospective européenne sur le cancer et la nutrition (EPIC), cohorte multicentrique de plus de 500,000 sujets provenant de 10 pays européens. La consommation d’alcool a d’abord été évaluée en regard du risque de CP. Les rôles des différents types d’alcools ainsi que du tabagisme dans la relation entre l’alcool et le CP ont été examinés. Cette évaluation a montré qu’une consommation d’alcool élevée était associée à une augmentation du risque de CP. Ensuite, la relation entre le Healthy Lifestyle Index, un indicateur combinant le passé tabagique, la consommation d’alcool, l’alimentation, l’anthropométrie et l’activité physique, et le risque de CP a été étudiée. Pour quantifier l’impact de l’amélioration de ces facteurs, des fractions de CP attribuables ont été estimées en considérant des scénarios hypothétiques où les participants adopteraient des modes de vie plus sains. L’adhérence à des habitudes saines était fortement et inversement associée au risque de CP. Ces travaux ont apporté des connaissances informatives sur l’étiologie du CP, et soutiennent le développement de mesures de santé publique promouvant la prévention du CP par l’adoption de modes de vie sains / Commonly diagnosed at late stage, pancreatic cancer (PC) is a highly fatal cancer with limited opportunities for early detection and effective treatment. The identification of modifiable risk factors may offer relevant scientific evidence for PC prevention. This doctoral research program investigated PC etiology through a comprehensive examination of the role of alcohol consumption and other lifestyle determinants in the occurrence of PC within the European Prospective Investigation into Cancer and nutrition (EPIC) study, a multi-center cohort involving more than 500,000 participants from 10 European countries. Alcohol intake was evaluated with respect to the risk of PC. The role of different alcoholic beverages and potential effect modification by smoking habits on PC risk were also examined. Findings from this evaluation provided epidemiological evidence that large intakes of alcohol were associated with an increased risk of PC.The association between the healthy lifestyle index, a score combining information on smoking history, alcohol intake, diet, obesity, and physical activity and the risk of PC was examined. To quantify the impact of modifying several lifestyle factors, population attributable fractions were estimated assuming counterfactual scenarios whereby study participants hypothetically moved towards healthier behaviors. Adherence to healthy lifestyle habits was strongly inversely related to PC. This comprehensive evaluation provides informative insights on the etiology of PC and supports the development and implementation of public health guidelines to promote individuals’ adoption of healthy lifestyle habits for PC prevention

Indiana University-Purdue University Indianapolis (IUPUI) / In order to elucidate the role of classical conditioning in food and alcohol co-consumption, the present study examined: (1) the effects of alcohol odor cues on alcohol and food cravings and attentional bias (bias in selective attention toward either food or alcohol pictures relative to neutral pictures); and (2) the role of alcohol odor cue elicited cravings and attentional biases on subsequent consumption. Participants (n = 77; mean age = 30.84, SD = 9.46; 51.9% female, 83.1% Caucasian) first completed the lab portion of the study. In this portion, they were exposed to alcohol and neutral odorants, after which their food and alcohol cravings and attentional bias were assessed. Participants then received an online survey the next day, on which they reported their level of food and alcohol consumption following the lab portion of the study. Using repeated measures analysis of covariance, alcohol odor cues were differentially effective in increasing food and alcohol attentional bias and cravings (Fs= 0.06 to 2.72, ps= 0.03 to 0.81). Using logistic and multiple regressions, alcohol odor cue elicited alcohol attentional bias, food attentional bias, and food cravings were associated with later alcohol consumption, but not with later food consumption or concurrent consumption (βs = -0.28 to 0.48, ps = 0.02 to 0.99; Exp(B)s = 0.95 to 1.83, ps = 0.33 to 0.91). Overall, alcohol odor cues can become conditioned stimuli that elicit conditioned food-related and alcohol-related responses, both of which persist long enough to motivate later alcohol consumption; however, these conditioned responses might not persist long enough to motivate later food or concurrent consumption. These findings serve as a first step in clarifying the role of classical conditioning in concurrent consumption. In particular, they suggest that additional empirical investigations are needed to: (1) clarify the classical conditioning mechanisms underlying concurrent consumption; and (2) examine whether interventions targeting classical conditioning mechanisms are effective for reducing alcohol use.

Background: Over the long term, unhealthy lifestyles can lead to many health problems, especially type 2 diabetes (T2D). The aim of the present study was to determine associations between lifestyle factors (smoking, alcohol consumption, physical activity, and diet) and T2D in American adults (aged ≥20 years) in a nationally representative sample. Methods: Data for 12 987 American adults participating in the National Health and Nutrition Examination Survey 2005–2014 were evaluated. Weighted multiple logistic regression models were used to examine associations between the four lifestyle factors and T2D after adjusting for demographics and socioeconomic status (SES). Prevalence trends for T2D were examined using Cochran–Armitage tests. Results: There was a significant increasing prevalence trend for T2D among American adults. Smokers and individuals consuming >12 alcoholic drinks in the past year were less likely to report having T2D than non‐smokers (odds ratio [OR] 0.41; 95% confidence interval [CI] 0.35–0.48) and those consuming(OR 0.46; 95% CI 0.39–0.55). Participants with light physical activity have a greater likelihood of having T2D than those engaging in vigorous physical activity (OR 5.72; 95% CI 4.30–7.60). Individuals consuming a poor diet were more likely to report having T2D than those eating an excellent diet (OR 1.18; 95% CI 1.02–1.41). All these relationships remained significant after adjustment for demographics and SES. Conclusion: All four lifestyle factors were significantly associated with T2D among American adults. The findings of the present study provide useful information for healthcare providers that may help them promote specific lifestyle modifications.
