Trata-se de uma série histórica. A fonte dos dados é o Projeto AMAMUNIC realizado em Assis – SP , no qual as mães ou responsáveis pelas crianças menores de um ano são entrevistadas, respondendo sobre o consumo (current status) de uma lista de alimentos no dia anterior, entre eles leite materno, outros tipos de leite, água, chá, suco, mingau, comida de sal, alimentos adoçados e outros. Os inquéritos alcançaram cobertura entre 50 e 88% do número estimado de nascidos vivos. Os indicadores da qualidade da alimentação infantil utilizados foram construídos para o presente estudo com base na literatura, considerando-se as informações disponíveis nos bancos de dados e as pequenas diferenças entre os questionários aplicados de 2001 a 2007 (versão 1) e em 2008 e 2011 (versão 2). A análise estatística envolveu regressão linear simples para teste de tendência com avaliação da adequação dos modelos pelo teste de normalidade dos resíduos por Shapiro-Wilk. Todos os indicadores referentes ao aleitamento materno apresentaram aumento positivo, sendo a tendência temporal estatisticamente significativa para Aleitamento Materno Exclusivo em menores de seis meses, com aumento de 1,77pontos percentuais/inquérito e Aleitamento Materno entre as crianças com seis a 12 meses de idade, com aumento de 1,02 ponto percentual/inquérito. O indicador Início do Aleitamento Materno na Primeira Hora de Vida apresentou percentuais “bons” (50 – 89%) segundo a OMS, nos dois anos (2008 e 2011) em que foi estudado. O indicador Oportunidade da alimentação complementar manteve-se estável, alcançando em torno de 80% das crianças na década. Metade das crianças, tanto entre as amamentadas como entre as não amamentadas, não alcançaram a Variedade mínima recomendada de 5 grupos alimentares consumidos no dia anterior. Destaca-se ainda a baixa proporção que alcançou a Frequência Mínima de Refeições, especialmente no grupo de crianças não amamentadas (7,8% em 2008 e 9,6% em 2011). Alimentos industrializados (sucos artificiais, refrigerantes, biscoitos/salgadinhos e alimentos adoçados) foram consumidos pelas crianças menores de seis meses (8,1% comeram biscoito/salgadinho industrializado em 2011) e entre as crianças com idade de seis a 12 meses o percentual de consumidores foi alto, chegando, no caso do consumo de biscoito/salgadinho industrializado, a 76% em 2008 e 65,5% em 2011. Vistos em conjunto, os resultados apontam situação distante das recomendações desde o início até o final do período para a maior parte dos indicadores, com evolução positiva dos indicadores de aleitamento materno e estabilidade nos indicadores relativos a alimentação complementar. / The aim of this study was to analyze temporal trend (2001-2011) of infant feeding practice indicators at Assis-SP, from seven cross-sectional surveys performed in 2001, 2003, 2004, 2005, 2007, 2008 and 2011 concomitantly with vaccination campaigns. This is a time series. The data source is the AMAMUNIC Project conducted in Assis - SP , in which mothers or guardians of children under one year old are interviewed, inquiring about the consumption (current status) of a list of foods, liquids and solids, the day before, including breast milk, other types of milk, water, tea, juice, porridge, salt food, sweetened foods and others. The surveys cover reached between 50 and 88% coverage of the estimated number of live births in those respective years. The variables / indicators of quality infant feeding used were built for this study based on the literature, considering the information available / not available in databases and small differences between the questionnaires 2001-2007 (version 1) and in 2008 and 2011 (version 2). Statistical analysis involved simple linear regression for trend test the adequacy of models residual analysis by Shapiro-Wilk. All breastfeeding indicators showed positive increase, having the temporal trend statistically significance Exclusive Breastfeeding for infants under six months infant, an increase of 1.77 percentage points by survey year and Breastfeeding among children six to 12 months of age old, an increase of 1.02 percentage points by survey year. Breastfeeding Initiation at the first hour of life presented "good" (50 to 89%) percentage according to the WHO, in the two years (2008 and 2011) they were studied. The Opportunity indicator remained stable, reaching around 80% of children in the decade. Half of the children, breastfed and non-breastfed, did not reach the minimum recommended Variety of 5 food groups consumed the day before. Low proportion that reached the Minimum Meal Frequency, especially in the non-breastfed group (7.8% in 2008 and 9.6% in 2011). Industrialized food (artificial juices, soft drinks, biscuits/snacks and sweetened foods) were consumed by children under six months old (8.1% ate industrialized biscuit / snack in 2011) and among children aged six to 12 months old the percentage of consumers was high, reaching, in case of industrialized biscuits/snacks consumption, up to 76% in 2008 and 65.5% in 2011. Taken together, the results indicate a far status of recommendation from the beginning to the end of the period for most indicators, with positive development in breastfeeding indicators and stability in the complementary feed indicators.

Introdução: A deficiência de ferro decorre, principalmente, da quantidade insuficiente de ferro na dieta para atender às necessidades nutricionais do indivíduo. Seu estágio mais grave, a anemia ferropriva, é reconhecida como um problema epidemiológico da maior relevância, sendo as crianças em idade pré-escolar, especialmente os lactentes, o grupo mais vulnerável à desnutrição. Objetivo: Identificar a prática alimentar e estimar sua capacidade de atender à recomendação e à necessidade de ferro das crianças de 6 a 23 meses de idade atendidas pela Estratégia Saúde da Família no Maranhão. Métodos: Estudo transversal de base populacional realizado no estado do Maranhão. A partir dos dados de consumo referido (inquérito recordatório de 24h), foram identificadas as práticas alimentares e calculadas quantidades de ferro, vitamina C e de energia a partir dos quais se quantificou o ferro biodisponível utilizando a equação de Monsen e Balintfly. Estimaram-se, ainda, as densidades do ferro total e do ferro biodisponível, além da adequação às recomendações da OMS. Resultados: Do total de 401 crianças estudadas, 7 crianças permaneciam em aleitamento materno exclusivo e dentre aquelas em que foi referida a alimentação complementar, o leite materno esteve presente entre 53 por cento delas, mesmo com a introdução do leite de vaca. A quantidade média de energia foi 826 kcal; ferro total 5,4 mg; ferro biodisponível 0,31 mg; densidade de Ferro/1000kcal= 6,4 e densidade de Ferro biodisponível/1000kcal= 0,34. Em comparação às recomendações, a ingestão energética apresentou valores abaixo da recomendação para mais de 50 por cento da população de estudo, em todas as faixas etárias, já em relação ao ferro, a partir dos 15 meses pelo menos 60 por cento das crianças alcançam a recomendação. Conclusão: A prática alimentar não se mostrou adequada para atender à recomendação e à necessidade de ferro diária, o que pode ser explicado pelo baixo consumo de alimentos fontes de ferro, com boa biodisponibilidade do mineral e de alimentos estimuladores de sua absorção. / Introduction: Iron deficiency is mainly due to the insufficient amount of iron in the diet to meet the nutritional needs of the individual. Its most severe stage, iron deficiency anemia is recognized as an epidemiological problem of the greatest importance, being the children of preschool age, especially infants, the group most vulnerable to malnutrition. Objective: To identify eating habits and estimate their ability to meet the recommendation and the need of iron for children 6-23 months of age served by the Family Health Strategy in Maranhão. Methods: Sectional study population-based study conducted in the state of Maranhão. From the data of consumption above (R24h), dietary practices and calculated amounts of iron, vitamin C and energy were identified from which the bioavailable iron was quantified using the equation of Monsen and Balintfly. Were estimated, furthermore, the densities of total iron and bioavailable iron, as well as compliance with WHO recommendations. Results: Of the 401 children studied, seven children remained in exclusive breastfeeding and among those that was reported complementary feeding, breast milk was present among 53per cent of them, even with the introduction of cow\'s milk. The average amount of energy was 826 kcal; Total Iron 5.4 mg; bioavailable iron 0.31 mg; density of Iron / 1000 kcal = 6.4 and density of bioavailable iron / 1000 kcal = 0.34. Compared to the recommendations, energy intake showed values below the recommendation for more than 50per cent of the study population in all age groups, as compared to iron, from 15 months at least 60per cent of children reach the recommendation. Conclusion: A diet was not adequate to meet the recommendation and the need for daily iron, which can be explained by low consumption of iron-rich foods with good bioavailability of the mineral-stimulating food absorption.

Introdução: Intervenções educacionais que preparam as equipes de saúde para a promoção e apoio a práticas alimentares saudáveis na infância podem ser efetivas na melhoria dos desfechos relacionados à saúde, nutrição e desenvolvimento infantil. Objetivo: Avaliar se a utilização de um material de educação permanente, elaborado para apoiar o tutor da Estratégia Amamenta e Alimenta Brasil (EAAB), é efetivo em melhorar indicadores de implementação da EAAB e indicadores de alimentação infantil em crianças menores de um ano. Métodos: Estudo de intervenção do tipo antes e depois realizado no município de Embu das Artes, SP. A intervenção consistiu em disponibilizar o Manual como material de apoio às atividades educativas sobre aleitamento materno e alimentação complementar que poderia ser usado por tutores da EAAB. Os tutores realizaram atividades de treinamento com as equipes de saúde durante oito meses. A coleta de dados ocorreu nos momentos pré e pós intervenção e em ambos foram aplicados: teste de conhecimentos sobre aleitamento materno (AM) e alimentação complementar (AC) aos tutores e profissionais de saúde; questionário auto aplicado junto aos gerentes para caracterização das UBS quanto às ações de promoção do AM e AC e entrevistas junto às mães sobre as práticas de alimentação da criança. Análise de dados: a tese gerou 3 manuscritos: No primeiro com o objetivo de avaliar as práticas de alimentação complementar das crianças de 6 a 12 meses utilizou-se análise de regressão de Poisson com modelagem hierarquizada para determinar os fatores associados ao consumo de alimentos ultra processados. O segundo e o terceiro manuscritos avaliaram os efeitos da intervenção. O segundo teve como foco a aplicação do Manual e sua influência na implementação da EAAB, utilizando duas abordagens: na quantitativa foram analisados dimensões e indicadores do processo de implementação com base no modelo lógico da intervenção e na qualitativa foi avaliada a percepção dos tutores acerca do processo de utilização do Manual. O terceiro manuscrito avaliou a efetividade do Manual na melhoria dos indicadores de alimentação infantil e para tanto utilizou-se análise de regressão de Poisson multinível com modelagem hierarquizada. Resultados: Manuscrito 1. A prevalência de consumo de alimentos ultra processados foi de 43,1% entre os menores de um ano. Baixa escolaridade materna e falta de atendimento na primeira semana de vida da criança foram fatores associados ao consumo de alimentos ultra processados. Manuscrito 2. O Manual foi utilizado por 9 dos 13 tutores do município e a intervenção em algum grau foi realizada em 11 de 13 UBS. Em média foram realizadas 3,5 [0-5] atividades complementares por UBS. A média de acertos dos tutores no teste de conhecimentos inicial foi 31,43 ± 5,25 e final 34,86 ± 4,45; p= 0,021. Entre os trabalhadores a média no pré-teste foi 26,09 ± 4,45 e no pós-teste 30,28 ± 3,55; p= 0,002. Em média o número de critérios de certificação alcançados pelas UBS foi maior depois da intervenção (pré 3 [1-6] versus pós 5 [3-6]) e apresentou consistência com a percepção de mudanças dos gerentes assim como com o número de atividades conduzidas pelos tutores. A avaliação da intervenção sob a ótica dos tutores revelou contribuições do uso do Manual para sua atuação. Manuscrito 3. A intervenção foi efetiva para a redução da falta de diversidade alimentar mínima e da falta de adequação alimentar, indicador que avalia a frequência, consistência e diversidade da AC. Porém, não se verificou efeito sobre a interrupção do AME. Conclusões: A investigação das práticas de alimentação infantil na população estudada evidenciou um alto consumo de alimentos ultra processados, reforçando a necessidade de intervenções que promovam práticas alimentares saudáveis na infância. O uso do Manual de Apoio ao Tutor melhorou o conhecimento dos tutores e trabalhadores da atenção básica e promoveu mudanças no processo de trabalho das equipes, refletidas no alcance dos critérios de certificação na EAAB, evidenciando o potencial de uma intervenção educativa usando metodologia crítico-reflexiva. Além disso, a intervenção mostrou-se efetiva para melhorar as práticas de alimentação complementar na população estudada. / Introduction - Educational interventions that prepare healthcare teams to promote infant feeding practices can be effective in improving outcomes related to health, nutrition and child development. Objective - To evaluate whether a continuing education tool (the Manual to Support Estratégia Amamenta e Alimenta Brasil (EAAB) Tutors) can improve EAAB implementation indicators and feeding practices in infants under one year of age. Methods - A before and after study was conducted at 13 primary healthcare units (PHU) in Embu das Artes, São Paulo. The intervention consisted in providing the Manual to support educational activities on breastfeeding and complementary feeding that could be used by tutors of EAAB. Tutors performed comprehensive training activities with healthcare teams over eight months. In both cross-sectional studies (pre and post intervention) a questionnaire was applied to the managers from the 13 PHU to characterize the healthcare service and actions to promote breastfeeding and complementary feeding; knowledge tests were also applied to tutors and health workers indicators of breastfeeding and complementary feeding practices were assessed by interviewing 1,159 mothers. Analysis: the thesis resulted in three manuscripts - The first one aimed to evaluate the complementary feeding practices of children from 6 to 12 months with a focus on the consumption of ultraprocessed foods (UPF) and multiple hierarchical models were performed. The second and third manuscripts evaluated the effects of the intervention. The second evaluated the application of the Manual and its influence on the implementation of EAAB, with two approaches: in the quantitative, the dimensions and indicators of the implementation process were analyzed based on the logical model of the intervention; in the qualitative approach the perception of the tutors about the process of manuals\' use was evaluated. The third manuscript evaluated the effectiveness of the Manual in improving indicators of infant feeding practices. Multivariate analysis was performed using Poisson multilevel regression Results: Manuscript 1: The prevalence of UPF consumption was 43.1% among children. Lower maternal education and lack of early assistance at the PHU were factors associated with higher UPF consumption. Manuscript 2: The Manual was used by 9 of 13 tutors and the intervention was performed in 11 of 13 PHU. In average, 3.5 [0-5] comprehensive training activities (CAs) were performed by PHU. The mean scores of tutors in the initial knowledge test were 31.43 ± 5.25 and final 34.86 ± 4.45; p = 0.021. Among health workers, the mean in the pre-test was 26.09 ± 4.45 and in the post-test 30.28 ± 3.55; p = 0.002. In average, the number of certification criteria fulfilled by the PHS was higher after intervention (before 3 [1-6]; after 5 [3-6]) and was consistent with the changes perceived by managers as well as with the number of CAs carried out by tutors. Tutors\' perception revealed contributions of the Manual for their action. Manuscript 3: The intervention was effective in reducing the lack of minimum food diversity and the lack of food adequacy, an indicator that evaluates the frequency, consistency and diversity of complementary feeding. However, there was no effect on interruption of exclusive breastfeeding. Conclusions: The investigation of infant feeding practices in the study population evidenced a high ultra-processed foods consumption, reinforcing the need of interventions to promote healthy eating practices in childhood. The use of the Manual to Support EAAB Tutors improved the knowledge of tutors and primary healthcare workers and promoted improvements in the work process of healthcare teams, reflected in the achievement of the EAAB certification criteria, evidencing the potential of an educational intervention using problem-based learning methodology. In addition, the intervention proved to be effective in improving complementary feeding practices in the study population.

Magister Public Health - MPH / Promotion of exclusive breastfeeding (EBF), (giving breast milk only without any solids or liquids), has proved to be very challenging in the South African context, although this infant feeding practice has been found to protect babies against diarrhoea and respiratory tract infections and to carry a lower risk of HIV infection than mixed feeding (breastfeeding combined with formula or solids). Study design: The PROMISE-EBF study is a multi-country cluster randomised trial to examine peer support to promote exclusive breastfeeding in Africa. For the South African site in the PROMISE-EBF study, three sites, Paarl, Rietvlei and Umlazi, were selected because of their different geographic settings and each site operated as a separate stratum for cluster selection and randomisation purposes. The clusters were then randomised into intervention and control arms making a total of 17 clusters in each arm. HIV positive and negative women in the intervention arm received support on their choice of infant feeding from the peer supporters who visited them at their homes while the women in the control group only received the standard infant feeding counselling and support provided by health care workers at health facilities. Data collection: Mothers were interviewed at recruitment during the antepartum period to establish eligibility, obtain informed consent and data on socio-economic status. Home visits were scheduled for data collection by trained data collectors at 3, 6, 12 and 24 weeks after birth. Analysis of results: This mini-thesis was a secondary analysis of the PROMISE-EBF data focusing on the South African data only. The data was adjusted for clustering and analysed using SAS. Comparison of variables between the intervention and control groups within sites was done. Results: A significant difference, regarding counselling and infant feeding practices, was observed among all women who received peer support compared to those who received the standard antenatal counselling, with more women in the intervention group (20.5%) practising EBF than those in the control group (12.8%) by Week 3. When the women's HIV status was considered, more than 65% of HIV positive and 40% of HIV negative women practised MF and EFF (giving formula milk only with no breast milk) throughout the study, respectively, regardless of the group they were in. For women who hadintended to practise EBF at recruitment, 33% in the control group and 20% in the intervention group actually practised EBF by Week 3. Regarding disclosure and feeding choice, 77.4% of women who had disclosed their HIV status actually practised MF versus 8.6% who practised EBF by Week 3.Conclusion: Community peer counselling should be strengthened as the results from this study showed that a high percentage of women who practised EBF were those who had received counselling, irrespective of their HIV status. The high percentage of HIV positive women who practised high risk feeding, despite receiving infant counselling, is of concern. Disclosure of the women's HIV status did not translate to them practising low risk infant feeding methods, which may suggest that there are other issues that determine the women's choice of infant feeding. / South Africa

Includes bibliographical references (p. 51-57). / Exclusive breastfeeding (mother's milk only, with the exclusion of all other food or drink) reduces breast milk transmission of HIV compared with mixed feeding. This study was part of formative work for a community-based un-blinded randomised controlled trial (RCT) in an urban township with high antenatal HIV prevalence in KwaZulu-Natal (KZN), South Africa. The RCT sought to determine whether an integrated package of home-based care delivered by community health workers (CHWs) increases uptake of prevention of mother-to-child-transmission (PMTCT) interventions and improves neonatal outcomes. One example of where counselling is used is in Behaviour Change Communication (BCC) approaches. A counselling booklet, used by CHWs during home visits, was part of the integrated package. The primary objective of this study was to document the socio-cultural context in which infant feeding and caring decisions were made. The secondary objective was to field test the draft counselling booklet for the RCT. Methods This qualitative study used focus groups (n=8 groups) and individual interviews (n=6). All participants, of unknown HIV status, were purposively sampled from the study site. The focus group participants included, in separate groups, eight MRC researchers; 14 pregnant women (two separate groups of seven each); six non-pregnant women; eight older women; five men and 15 CHWs (separated into two groups). Results Data showed that socio-cultural factors, like the lack of social support systems; uncertainty regarding the role of men in infant feeding and caring issues; local beliefs and practices that encouraged risky infant caring practices; the lack of supply of formula and CHWs' lack of breastfeeding knowledge and experience; and HIV-related stigma may directly or indirectly, drive mothers to practice non-exclusive infant feeding. BCC principles acknowledge that people are affected greatly by social pressures exerted not only by their peers, but also by their larger communities (Bentley et al., 1999). For vi example, with regard to the support systems, both pregnant as well as younger women felt that feeding and caring decisions regarding their infants were mostly made by older women ' their husbands were seldom involved in such decisions. In relation to HIV-related stigma, many pregnant women felt that some clinics were not very supportive regarding HIV disclosure. In terms of health system factors, CHWs said that they were sometimes ill-equipped to deal with issues of disclosure due to a lack of training and confusion around the key feeding and caring messages. With regard to infant caring practices, the data revealed risky practices (using soap enemas and inappropriate hand washing practices), even amongst CHWs. Participants said they would share the booklet with others in the community as it taught them important lessons regarding infant feeding and caring practices. For some, the pictures in the booklet enhanced their understanding of 'old' messages. Participants identified several weaknesses in the booklet and suggested that it be less repetitive; that voluntary counselling and testing (VCT) be given priority in earlier rather than later visits; that unfamiliar terms is explained; more pictures included; and the general tone of messages improved. Literacy rates were low among older women and some men in the study. Conclusion and Recommendations Socio-cultural factors drive mothers to practice non-exclusive feeding and care for their infants in ways that may unwittingly increase the risk of HIV transmission. There is a need for CHWs to include family members in discussions about feeding so that they can change their thinking around infant-feeding and caring issues. The data suggests that VCT is not given priority in the counselling booklet and support is lacking in some clinics, therefore policy makers should ensure that support for VCT becomes a priority in the future. Furthermore, some CHWs were confused about the messages they are disseminating, therefore, the training that facility managers give to CHWs should be adapted to suit socio-cultural contexts so that CHWs are better equipped to communicate messages pertaining to infant feeding and caring appropriately to mothers. With the data revealing general acceptability of risky infant caring practices, even amongst CHWs, the vii health system needs to look at how it will effectively change health-related practices among health professionals. With literacy rates being low among older women and some men in the study, it was therefore recommended that gaining skills in materials design and improving CHWs' understanding of the BCC process, booklets such as this one needs to be designed together with the primary user in mind.

Le surpoids (embonpoint et obésité) chez l’enfant est un problème préoccupant qui prend de plus en plus d’ampleur. Le rôle du parent dans cette problématique est prédominant, puisqu’il assure la disponibilité des aliments, choisit les mets présentés, joue le rôle de modèle dans l’acte alimentaire et interagit avec l’enfant durant les prises alimentaires pour guider son comportement alimentaire. Le parent offre et façonne l’environnement dans lequel évolue l’enfant. Cette thèse explore le rôle de la mère dans cet environnement. Le parent utilise diverses pratiques alimentaires pour guider l’alimentation de l’enfant. Certaines sont douces, comme encourager positivement l’enfant à essayer un aliment (ex. Goûtes-y, moi je trouve ça très bon!) et d’autres plus coercitives (ex. Tu ne sors pas de table sans avoir terminé ton assiette). Les interactions parent-enfant lors de la prise alimentaire sont susceptibles d’avoir différentes conséquences sur l’alimentation de l’enfant, modifiant possiblement les apports alimentaires, les préférences, la néophobie et le statut pondéral. Les interactions parent-enfant en général, donc hors du contexte précis de l’alimentation, peuvent aussi influencer les comportements alimentaires de l’enfant. L’objectif général de cette thèse est d’explorer les relations entre les interactions parent-enfant en général, aussi nommées « styles parentaux » (SP), les interactions parent-enfant dans le contexte alimentaire, portant le nom de «styles parentaux alimentaires» (SPA), les stratégies alimentaires utilisées par les parents pour guider l’alimentation de l’enfant, nommées « pratiques alimentaires parentales » (PAP), les comportements alimentaires de l’enfant et le statut pondéral de ce dernier. Cette thèse comprend 4 objectifs spécifiques. D’abord, d’examiner les relations entre les SP, les SPA et les PAP. Dans un deuxième temps, les relations entre les SPA, le comportement alimentaire de l’enfant (préférence et fréquence de consommation) et le statut pondéral de l’enfant seront explorées. Puis, l’existence de relations entre l’usage de PAP et le comportement alimentaire de l’enfant sera évaluée. Finalement, les relations entre les attitudes de la mère à l’égard de son poids et de celui de son enfant et du comportement néophobique de l’enfant seront explorées. Cent vingt-deux mères d’enfants d’âge préscolaire, de 3 à 5 ans, ont été recrutées par des milieux de garde de l’île de Montréal et ont complété et retourné un questionnaire auto-administré portant sur le style parental, style parental alimentaire, les PAP, les fréquences de consommation de l’enfant, les préférences de l’enfant pour certains aliments et groupe d’aliments, la néophobie de l’enfant, le poids et la taille de l’enfant, le régime actuel de la mère, la perception du poids de l’enfant, la préoccupation face au poids de l’enfant ainsi que la description du profil familial. Les SP, les SPA et les PAP montrent des corrélations. Les SPA, plus particulièrement les deux échelles qui les composent (exigence et sensibilité) montrent des corrélations avec la consommation et la préférence pour certains aliments. Des différences sont aussi notées entre les différents SPA et le statut pondéral de l’enfant et certains comportements alimentaires. La présente thèse suggère une implication de trois concepts, soient les SP, les SPA et les PAP, dans la dynamique alimentaire de la dyade mère-enfant. Des relations importantes entre les SPA et les préférences alimentaires sont suggérées. Les futures recherches dans ce domaine devront évaluer l’impact relatif des PAP, des SP et des SPA sur le comportement alimentaire (consommation et préférence) et le poids de l’enfant. Une intervention efficace visant des changements de comportements alimentaires auprès des familles devra adresser à la fois les PAP, mais aussi les SP et les SPA. / Childhood overweight is a fast growing and worrisome problem. The role of parents in this situation is of great importance as they ensure food availability, chose the presented meals, act as role models in the feeding act and interact with children during feeding to guide their eating behavior. The parent offers and molds the environment in which the child will evolve. This thesis explores the mother's role within this environment. The parent uses various feeding practices to guide the child's food choices. Some are kind, such as positively encouraging the child to taste new foods, (e.g., give this a taste, I think it's delicious!) while others are coercive (e.g., you are not leaving from this table until you finish your plate). Parent-child interactions during mealtime are likely to have different consequences on the child's eating habits, possibly modifying his food intake, food preferences, neophobia and weight status. Parent-child interactions can also influence a child's eating behavior without necessarily being within a food setting. The main objective of this thesis is to explore the relationship between the general parent-child interactions, also known as the parenting style, the parent-child interactions in a food setting, known as the feeding style, the feeding strategies used by the parents to guide the child's food choices, known as the feeding practices, the child's eating behavior and his weight status. This thesis has 4 specific objectives. First, to examine the relationship between the parenting style, the feeding style and the feeding practices. Second, to study the relationship between the feeding style, the child's eating behavior (food preferences and consumption frequency) and his weight status. Thirdly, to evaluate the existence of a relationship between the feeding practices and the child's eating behavior. Finally, to explore relations between mother’s attitudes toward her weight and her child’s weight and neophobic behavior. One hundred twenty-two mothers of preschoolers aged 3 to 5, were recruited by daycare centers on the island of Montreal and completed and auto-administered questionnaire on parenting style, feeding style, feeding practices, child consumption frequency, child preference for certain foods and food groups, child neophobia, child weight and height, the mother's diet, the mother's perception of the child's weight, the mother's concern regarding the child's weight and a description of the family profile. Parenting styles, feeding style and feeding practices display correlations among themselves. The feeding styles, more precisely the two scales that describe them (demandingness and sensibility), show correlations with the consumption and preference for certain foods. Differences were also noted between various feeding styles and child weight status and certain eating behaviors. The following thesis suggests that three concepts are implicated in the feeding dynamic of the mother-child dyad; the parenting style, the feeding style and the feeding practices. It is suggested that the feeding style and food prerefences are correlated. Future research in this field will need to evaluate the relative impact of feeding practices, parenting styles and feeding styles on eating behavior (consumption and preferences) and child weight. An effective intervention seeking to change eating behavior among families will need to address parent feeding practices as well as parenting style and feeding style.

Contexte. De plus en plus d’enfants fréquentent les milieux de garde et y consomment leur repas. Les éducatrices présentes constituent des modèles dont les attitudes et les pratiques alimentaires peuvent contribuer au développement des habitudes alimentaires des enfants. Toutefois, peu d’études ont été menées sur le sujet. Objectifs. Décrire les attitudes et les stratégies d’éducatrices en milieux de garde au Québec à l’égard de l’alimentation des enfants et dégager les styles alimentaires dominants. Méthode. La collecte de données a eu lieu par sondage sur le site Web www.nospetitsmangeurs.org. À partir de 86 énoncés, la recherche a documenté les styles et pratiques alimentaires des éducatrices au moyen de huit mises en situation : mets principal non apprécié par l’éducatrice, aliment particulier non apprécié par un enfant, nouveau mets non désiré par les enfants, enfant difficile ne voulant pas manger, enfant qui n’a pas faim, fillette avec embonpoint, fillette de petit poids et enfant n’ayant pas terminé son repas. Analyse statistique. Des statistiques descriptives, des échelles de fiabilité et des corrélations ont été générées. Des tests de t pour échantillons appariés ont également été utilisés pour évaluer le degré relatif des styles alimentaires. Résultats. Au total, 371 répondants ont rempli l’ensemble du questionnaire. Globalement, les éducatrices étudiées utilisent le style alimentaire démocratique. Celles-ci mentionnent représenter des modèles pour les enfants. Elles encouragent aussi les enfants à manger et utilisent la division des responsabilités. Paradoxalement, la pratique alimentaire associée au style autoritaire la plus utilisée est la pression à manger, pratique en opposition avec le concept de division des responsabilités. Conclusion. Cette étude indique que les éducatrices démontrent des attitudes positives à l’égard de l’alimentation des enfants. Malgré certaines discordances à l’égard de stratégies utilisées, ces résultats sont encourageants, car le style alimentaire démocratique permet aux enfants de reconnaitre leurs signaux de faim et de satiété. / Context. More and more children go to daycare centres and have their meals in these settings. Caregivers are role models whose attitudes and feeding practices may contribute to the development of children's eating habits. However, few studies have been conducted on this subject. Objectives. To describe the attitudes and strategies of caregivers working in daycare settings with respect to children’s diets and identify dominant feeding styles. Methodology. Data collection was conducted by means of a survey on the www.nospetitsmangeurs.org website. A total of 86 statements were used to document the feeding styles and practices of caregivers as revealed through eight scenarios: a main dish not liked by the caregiver, a specific food not liked by a child, a new meal refused by children, a picky eater who does not want to eat, a child who is not hungry, an overweight little girl, a underweight girl and a child who has not finished his/her meal. Statistical analysis. Descriptive statistics, reliability scales and correlations were generated. T tests for paired samples were also used to assess the relative importance of feeding styles. Results. A total of 371 respondents completed the questionnaire. Overall, the caregivers use a democratic feeding style. They mentioned being role models for the children. They also encourage children to eat and they favor division of responsibilities. However, the most widely used feeding practice related to the authoritarian style is the pressure to eat, a practice contrary to the division of responsibilities concept. Conclusion. This study indicates that caregivers demonstrate positive attitudes towards child feeding. Despite some discrepancies with respect to strategies used, these results are encouraging since a democratic feeding style allows children to recognize their hunger and satiety cues.

Contexte. Les attitudes et comportements alimentaires développés pendant la petite enfance influencent grandement la relation future du mangeur à l’égard des aliments. Le parent s’avère en ce sens des plus déterminants. Objectifs. Cette étude vise à connaître les pratiques et attitudes employées par les parents québécois d’enfants d’âge préscolaire pour favoriser le « bien manger » ainsi que le repas familial agréable. Méthodes. La collecte de données a été effectuée à l’aide de cartes postales qui étaient distribuées dans six cent cinquante Centres de la Petite Enfance parmi les mille retrouvés dans la province de Québec pour ensuite être remises aux parents. L’analyse des réponses aux deux questions ouvertes figurant sur la carte postale a été effectuée en se basant sur le modèle des prises alimentaires de Jean-Pierre Poulain. Résultats. Plus de mille (1257) cartes postales ont été retenues aux fins d’analyses. Les données recueillies permettent dans un premier temps de connaître la perception des parents quant à la notion de manger bien. Les notions de qualité et de quantité, diamétralement opposées se démarquent. Dans le cas du repas familial, la discussion, la présence de tous les membres à table ainsi que l’absence de télévision sont abondamment mentionnées. Conclusion. Cette étude permet de constater la variété des stratégies employées par les parents québécois au moment du repas. Ces données d’une grande pertinence pour la santé publique permettront de cibler les messages clés à promouvoir auprès de ces acteurs d’influence dans le développement des habitudes alimentaires des tout petits. / Context. Food attitudes and behaviors developed during early childhood greatly influence the future relationships that children will have with food. Parents play a major role in this part of their preschool child’s life. Objective The main goal of this study is to explore attitudes and behaviors that Quebec parents adopt at meal time with their preschooler in order to encourage healthy eating practices as well as enjoyable family meals. Methodology. To collect data, postcards, an innovative tool, were sent to six hundred fifty day-care centres, also known as Centres de la petite enfance (CPE), of which there are more than a thousand in Quebec. The postcards were then distributed to parents, who were asked to respond to two open-ended questions. Analysis of the qualitative data was based on Jean-Pierre Poulain’s food intake model. Results. More than a thousand (1,257) postcards were used in the analysis. Data collected illustrate first and foremost the vision that parents have of healthy eating and reveal two diametrically opposed perspectives: quality and quantity. With regard to family meals, respondents frequently mentioned conversation at the table, the presence of all family members and the absence of television while eating. Conclusion. Findings from this study show the diverse strategies used by Quebecers during mealtimes. The data are essential to defining key public health messages about eating habits for children that should be promoted among these influential actors.

Choice of nutrition has a great effect on the early development of human growth. Despite increased knowledge on the benefit of breastfeeding to both mother and child, some mothers still choose to formula feed. The purpose of this study is to explain how maternal health contributes to choices. The theory of maternal role attainment and the social cognitive theory are used to evaluate these feeding choices. This study tests for the association between maternal weight status and choice of infant feeding practices, the association between postpartum depression and choice of feeding and finally, if depression mediates the relationship between maternal weight gain and infant feeding choices. This retrospective cohort study employed a quantitative approach, utilizing secondary data with a sample size of 4902, retrieved from Infant Feeding Practices Study II. The data contained information on pregnant women in their third trimester until the first year of infants' life. Logistic regression was employed to answer these research questions. The result indicated that compared to those who are obese, mothers with normal weight are 29.6% more likely to breastfeed. Depressed mothers are 45.9% less likely to breastfeed. There is no possible mediation effect identified in this study. Further studies may need to collect mother's depression status prior to conception. Based on the outcome of this study, there is a need for caregivers to identify at-risk mothers prior to delivery while offering solutions that contribute to better feeding choices. For social change, mothers who are overweight or those experiencing depression prior to conception will make better feeding choices if they receive adequate support and counseling on the implication of their health condition on their infants.
