The aim of the present thesis was to study elderly self-managing and disabled women’s dietary intake and meals in relation to age, household structure (single-living or cohabitant), disability and cooking ability. The women were aged 64-88 years and living at home, in the mid-eastern part of Sweden. The self-managing women were randomly selected. The disabled women – suffering from Parkinson's disease, rheumatoid arthritis or stroke – were selected from patient records. A total of 139 self-managing and 63 disabled women participated. Two dietary assessment methods were used: a repeated 24-h recall and a three-day estimated food diary, providing dietary intake for five non-consecutive days. The results indicate that elderly women still living in their homes seem to manage a sufficient dietary intake despite disability and high age. The reported energy intakes in all groups of women were low, which might be explained by an actual low intake and/or under-reporting. The portion sizes seemed to be smaller in the highest age group, leading to lower intakes of some nutrients. Thus also the nutrient density of the food should be given greater consideration. The meal pattern was shown to be regular and the distribution of main meals and snacks was found to be satisfactory. Meals and snacks that were defined as such by the women themselves thus seem to be more significant from an energy and nutritional perspective. Perceived cooking ability co-varied with energy and nutrient intake as well as with meal pattern. Further, a qualitative dietary assessment method, FBCE, was analysed. It was concluded that it must be supplemented with a dietary assessment method providing energy intake figures to ensure a sufficient intake, especially when studying groups at risk for low energy intake. Furthermore, the aim was to perform a dropout analysis. When studying older women and food, a low participation rate might be expected since the most active, the very ill as well as the disabled tend to decline participation, but also since food is a gender issue. Food could, especially for women, be a sensitive area of discussion, even though older women seem to choose "healthy foods" and eat "proper meals".

Besides these, the dietary habits and lifestyle have also been considered unsuitable impacting the development of chronic diseases. The study objectives were: (1) estimate the prevalence of lipid profile and correlate with body mass index (BMI), waist circumference (WC) and waist / height ratio (WHR) in adolescents, considering the maturation sexual, (2) know the sources of variance in the diet and the number of days needed to estimate the usual diet of adolescents and (3) describe the dietary patterns and lifestyle of adolescents, family history of CVD and age correlates them with the patterns of risk for CVD, adjusted for sexual maturation. A cross-sectional study was performed with 432 adolescents, aged 10-19 years from public schools of the Natal city, Brazil. The dyslipidemias were evaluated considering the lipid profile, the index of I Castelli (TC / HDL) and II (LDL / HDL) and non-HDL cholesterol. Anthropometric indicators were BMI, WC and WHR. The intake of energy, nutrients including fiber, fatty acids and cholesterol was estimated from two 24-hour recalls (24HR). The variables of lipid profile, anthropometric and clinical data were used in the models of Pearson correlation and linear regression, considering the sexual maturation. The variance ratio of the diet was calculated from the component-person variance, determined by analysis of variance (ANOVA). The definition of the number of days to estimate the usual intake of each nutrient was obtained by taking the hypothetical correlation (r) &#8805; 0.9, between nutrient intake and the true observed. We used the principal component analysis as a method of extracting factors that 129 accounted for the dependent variables and known cardiovascular risk obtained from the lipid profile, the index for Castelli I and II, non-HDL cholesterol, BMI, and WC the WHR. Dietary patterns and lifestyle were obtained from the independent variables, based on nutrients consumed and physical activity weekly. In the study of principal component analysis (PCA) was investigated associations between the patterns of cardiovascular risk factors in dietary patterns and lifestyle, age and positive family history of CVD, through bivariate and multiple logistic regression adjusted for sexual maturation. The low HDL-C dyslipidemia was most prevalent (50.5%) for adolescents. Significant correlations were observed between hypercholesterolemia and positive family history of CVD (r = 0.19, p <0.01) and hypertriglyceridemia with BMI (r = 0.30, p <0.01), with the CC (r = 0.32, p <0.01) and WHR (r = 0.33, p <0.01). The linear model constructed with sexual maturation, age and BMI explained about 1 to 10.4% of the variation in the lipid profile. The sources of variance between individuals were greater for all nutrients in both sexes. The reasons for variances were &#61500; 1 for all nutrients were higher in females. The results suggest that to assess the diet of adolescents with greater precision, 2 days would be enough to R24h consumption of energy, carbohydrates, fiber, saturated and monounsaturated fatty acids. In contrast, 3 days would be recommended for protein, lipid, polyunsaturated fatty acids and cholesterol. Two cardiovascular risk factors as have been extracted in the ACP, referring to the dependent variables: the standard lipid profile (HDL-C and non-HDL cholesterol) and "standard anthropometric index (BMI, WC, WHR) with a power explaining 75% of the variance of the original data. The factors are representative of two independent variables led to dietary patterns, "pattern 130 western diet" and "pattern protein diet", and one on the lifestyle, "pattern energy balance". Together, these patterns provide an explanation power of 67%. Made adjustment for sexual maturation in males remained significant variables: the associations between puberty and be pattern anthropometric indicator (OR = 3.32, CI 1.34 to 8.17%), and between family history of CVD and the pattern lipid profile (OR = 2.62, CI 1.20 to 5.72%). In females adolescents, associations were identified between age after the first stage of puberty with anthropometric pattern (OR = 3.59, CI 1.58 to 8.17%) and lipid profile (OR = 0.33, CI 0.15 to 0.75%). Conclusions: The low HDL-C was the most prevalent dyslipidemia independent of sex and nutritional status of adolescents. Hypercholesterolemia was influenced by family history of CVD and sexual maturation, in turn, hypertriglyceridemia was closely associated with anthropometric indicators. The variance between the diets was greater for all nutrients. This fact reflected in a variance ratio less than 1 and consequently in a lower number of days requerid to estimate the usual diet of adolescents considering gender. The two dietary patterns were extracted and the pattern considered unhealthy lifestyle as healthy. The associations were found between the patterns of CVD risk with age and family history of CVD in the studied adolescents / As dislipidemias e o excesso de peso corporal em adolescentes, quando associados, sugerem uma progress?o dos fatores de risco modific?veis para as doen?as cardiovasculares (DCV). Al?m destes, os h?bitos alimentares e de estilo de vida inadequados, tamb?m t?m sido considerados impactantes no desenvolvimento de doen?as cr?nicas. Os objetivos do estudo foram: (1) estimar a preval?ncia das altera??es do perfil lip?dico e correlacionar com o ?ndice de massa corporal (IMC), a circunfer?ncia da cintura (CC) e a raz?o cintura/altura (RCA) em adolescentes, considerando a matura??o sexual; (2) conhecer as fontes de vari?ncia da dieta e o n?mero de dias necess?rios para estimar a dieta habitual dos adolescentes e (3) descrever os padr?es diet?ticos e de estilo de vida dos adolescentes, a hist?ria familiar positiva de DCV e a idade e correlacion?-los com os padr?es de risco para DCV, ajustados pela matura??o sexual. Foi conduzido um estudo transversal com 432 adolescentes de escolas p?blicas municipais da cidade do Natal, RN, Brasil, com idade entre 10-19 anos. As dislipidemias foram avaliadas considerando o perfil lip?dico, o ?ndice de Castelli I (CT/HDL) e II (LDL/HDL) e o colesterol n?o-HDL. Os indicadores antropom?tricos inclu?dos foram o IMC, a CC e a RCA. A ingest?o de energia, dos macronutrientes inclusive a fibra, dos ?cidos graxos e do colesterol foi estimada a partir de dois recordat?rios de 24h (R24h). As vari?veis do perfil lip?dico, antropom?tricas e cl?nicas foram usadas nos modelos de correla??o de Pearson e de regress?o linear multivariada, considerando a matura??o sexual. A raz?o de vari?ncia da dieta foi calculada entre o componente da vari?ncia intrapessoal e interpessoal, determinada pela an?lise de vari?ncia (ANOVA). A xv defini??o do n?mero de dias para a estimativa da ingest?o habitual de cada nutriente foi obtida considerando a correla??o hipot?tica de (r) &#8805; 0,9, entre a ingest?o de nutrientes verdadeira e a observada. Utilizou-se a an?lise de componentes principais (ACP) como m?todo de extra??o dos fatores que representaram as vari?veis dependentes denominadas de risco cardiovascular e obtido a partir do perfil lip?dico, do ?ndice de Castelli I e II, do colesterol n?o-HDL, do IMC, da CC e da RCA. Os padr?es diet?ticos e do estilo de vida foram obtidos a partir das vari?veis independentes, com base nos nutrientes consumidos e na atividade f?sica semanal. No estudo da ACP foram investigadas as associa??es entre os padr?es de risco cardiovascular com os padr?es diet?ticos e do estilo de vida, idade e com a hist?ria familiar positiva de DCV, por meio da an?lise bivariada e regress?o log?stica m?ltipla ajustada pela matura??o sexual. O baixo HDL-c foi a dislipidemia mais prevalente (50,5%) nos adolescentes. Foram verificadas correla??es significativas entre a hipercolesterolemia e a hist?ria familiar positiva de DCV (r=0,19, p<0,01); e a hipertrigliceridemia com o IMC (r=0,30, p<0,01), com a CC (r=0,32, p<0,01) e com a RCQ (r=0,33, p<0,01). O modelo linear constru?do com a matura??o sexual, idade e IMC explicaram cerca de 1 10,4% da varia??o dos valores do perfil lip?dico. As fontes de vari?ncia interpessoal foram maiores para todos os nutrientes, em ambos os sexos. As raz?es de vari?ncias foram &#61500; 1 para todos os nutrientes sendo mais elevadas no sexo feminino. Os resultados sugerem que para avaliar a dieta destes adolescentes, 2 dias de R24h seriam suficientes para consumo de energia, carboidratos, fibra, ?cidos graxos saturados e monoinsaturados. Diferentemente, 3 dias seria o recomendado para a prote?na, xvi lip?deos, os ?cidos graxos poliinsaturados e o colesterol. Dois fatores denominados de risco cardiovascular foram extra?dos na ACP, referentes ?s vari?veis dependentes: o padr?o perfil lip?dico (HDL-C e colesterol n?o-HDL) e o padr?o indicador antropom?trico (IMC, CC, RCA), com um poder de explica??o de 75% da vari?ncia dos dados originais. Os fatores representativos das vari?veis independentes originaram dois padr?es diet?ticos, padr?o dieta ocidental e padr?o dieta prot?ica ; e um relativo ao estilo de vida, padr?o equil?brio energ?tico . Em conjunto, estes padr?es fornecem um poder de explica??o de 67%. Feito o ajuste pela matura??o sexual, permaneceram significativas no sexo masculino as seguintes vari?veis: as associa??es entre ser p?bere e o padr?o indicador antropom?trico (OR=3,32, IC% 1,34-8,17); e entre a hist?ria familiar de DCV e o padr?o perfil lip?dico (OR=2,62, IC% 1,20-5,72). No sexo feminino, identificaram-se associa??es entre a idade ap?s a primeira fase da puberdade com os padr?es indicadores antropom?tricos (OR=3,59, IC% 1,58-8,17) e do perfil lip?dico (OR=0,33, IC% 0,15-0,75). Conclus?es: O baixo HDL-c foi a mais prevalente dislipidemia independente do sexo e do estado nutricional dos adolescentes. A hipercolesterolemia teve influ?ncia da hist?ria familiar positiva de DCV e da matura??o sexual; por sua vez, a hipertrigliceridemia foi fortemente associada aos indicadores antropom?tricos. A vari?ncia interpessoal da dieta foi a maior para todos os nutrientes. Tal fato repercutiu em uma raz?o de vari?ncia menor que 1 e consequentemente em um menor n?mero de dias necess?rios para se estimar a dieta habitual dos adolescentes, considerando o sexo. Os dois padr?es diet?ticos extra?dos foram considerados n?o saud?veis e o padr?o estilo de vida como saud?vel. As associa??es encontradas foram entre os padr?es de xvii risco para DCV com a idade e a hist?ria familiar positiva de DCV nos adolescentes estudados

O gasto energético total (GET) pode ser usado como medida da ingestão energética (IE). Existe um constante sub-relato da IE obtida por métodos de avaliação do consumo alimentar, mas poucos estudos o investigaram em nações em desenvolvimento. Objetivos: a) comparar a validade das estimativas de IE de um questionário de freqüência alimentar, três recordatórios alimentares e um diário alimentar de três dias, segundo a água duplamente marcada; b) determinar a influência da prática de atividade física, do índice de massa corporal e de fatores psicossociais no sub-relato e; c) comparar as taxas de sub-relato entre agrupamentos de padrões alimentares. Métodos: Sessenta e cinco mulheres responderam aos métodos de inquérito supracitados, a partir dos quais foi estimada a IE. O GET foi medido pela água duplamente marcada. A prática de atividade física, índice de massa corporal, escolaridade, renda, idade, conhecimento nutricional, insatisfação corporal, restrição dietética, compulsão alimentar e o desejo de aceitação social foram correlacionados ao sub-relato. Os padrões alimentares foram obtidos pela análise de cluster. Resultados: O GET foi de 2.622 ± 490 kcal, enquanto que a IE, mensurada respectivamente pelo recordatório, diário e questionário, foi de 2.078 ± 430 kcal; 2.044 ± 479 kcal e 1.984 ± 832 kcal. A proporção de sub-relatores foi de 24,6% para o recordatório, 29,2% para o diário e 53,8% para o questionário (p < 0,005). Os sub-relatores apresentaram menores médias de renda e escolaridade e maiores valores de idade, insatisfação corporal e desejo de aceitação social. O sub-relato foi mais comum no padrão alimentar mais frugal. Conclusão: Os três métodos de avaliação do consumo alimentar apresentaram erros sistemáticos, embora o questionário de freqüência alimentar tenha tido o pior desempenho. O sub-relato foi influenciado por diversos fatores psicossociais e variou conforme o padrão alimentar relatado, o que pode comprometer a avaliação do consumo / Total energy expenditure (TEE) may be used as a measure of energy intake (EI). There is a constant underreporting of EI obtained by dietary assessment methods, but few studies have investigated it in developing nations. Objectives: a) to compare the validity of EI estimates obtained by a food-frequency questionnaire, three diet recalls and a three-day food record; b) to determine the influence of physical activity, body mass index and psychosocial factors on underreporting and; c) to compare underreporting rates between dietary pattern\'s clusters. Methods: Sixty-five women completed the dietary assessment methods, which were used to estimate EI. TEE was measured by doubly labeled water. Physical activity practice, body mass index, education, income, age, nutritional knowledge, body dissatisfaction, dietary restraint, binge eating and social desirability were correlated to underreporting. Dietary patterns were obtained by cluster analysis. Results: TEE was 2,622 ± 490 kcal, while EI, measured respectively by the diet recall, food record and food-frequency questionnaire, was 2,078 ± 430 kcal; 2,044 ± 479 kcal and 1,984 ± 832 kcal. Proportion of underreporters was 24.6% (recall), 29.2% (record) and 53.8% (questionnaire) (p < 0.005). Underreporters had smaller income and education and greater age, body dissatisfaction and social desirability. Underreporting was more common in the \'frugal foods\' pattern. Conclusions: The three dietary assessment methods presented systematic errors, although the foodfrequency questionnaire had the worst performance. Underreporting was influenced by psychosocial factors and varied according the reported dietary pattern, which may compromise dietary assessment

Le nombre de personnes ayant eu un cancer, dans le monde, n’a jamais était aussi élevé. Même si le bénéfice de l’adoption de comportements favorables à la santé, notamment en termes d’alimentation, suite à un diagnostic de cancer a été suggéré, peu d’études se sont spécifiquement intéressées à l’influence d’un diagnostic de cancer sur l’évolution à long terme de l’alimentation, ainsi qu’à l’impact de l’environnement socio-économique et du type de cancer (localisation et stade au diagnostic) dans cette relation. Par ailleurs, l’alimentation étant un des déterminants majeurs de la santé, de nombreuses études épidémiologiques ou cliniques souhaitent recueillir de plus en plus fréquemment les habitudes alimentaires de leurs sujets mais redoutent la durée de recueil avec les outils existants. L’objectif de ce travail doctoral était de 1) mieux caractériser les relations entre alimentation, environnement socio-économique et survenue de cancer, notamment chez les patients ayant eu un cancer, et 2) de créer et valider un outil de recueil alimentaire court, adapté au régime français, afin d’harmoniser le recueil des données alimentaires sur le plan national. À partir des données de plus de 50 000 femmes de la cohorte E3N, une augmentation de la consommation de fruits et légumes, utilisés ici comme marqueur de la qualité de l’alimentation, a été observée uniquement chez les femmes ayant eu un cancer du sein de stade avancé (II-III-IV). Cette augmentation était davantage prononcée dans certaines strates socio-économiques (chez les femmes à niveau d’éducation élevée et chez celles vivant dans le Sud, par exemple). En parallèle, un questionnaire de fréquence alimentaire court, capable d’évaluer rapidement l’alimentation des individus, a été développé en format papier et en ligne. La version papier de ce questionnaire a été validée dans une population de 127 patients atteints de maladie rénale chronique et la version numérique sur 92 adultes issus de la population générale. Ce travail précise l’influence complexe de l’environnement socio-économique sur l’évolution de l’alimentation chez les patients ayant eu un cancer. Des études complémentaires seront nécessaires pour comprendre les freins à l’adoption de comportements alimentaires favorables à la santé. Les recommandations nécessiteraient d’être modulées en fonction du niveau socio-économique des individus afin de réduire les inégalités socio-économiques en lien avec l’alimentation et la survenue de cancer. Finalement, ce travail doctoral va permettre de mettre à disposition de la communauté scientifique un outil de recueil alimentaire court, fiable et actualisé, qui sera commun à l’ensemble des groupes de population française. / The number of cancer survivors is increasing worldwide. Several studies have demonstrated a potential beneficial impact of healthy lifestyle factors, including the diet, on cancer survival, but only a few studies have evaluated the influence of a cancer diagnosis on the long-term evolution of the diet, taking into account the socioeconomic environment of individuals as well as cancer characteristics such as the site and stage at diagnosis. Moreover, considering that the diet is one of the main determinants of health, an increasing number of epidemiological studies aim to collect dietary data but are limited by the fact that dietary data collection is very time-consuming for participants as well as for researchers. The objective of this project was 1) to better characterize the complex relations between diet and socio-economic environment among women who had cancer and 2) to develop and validate a short tool able to quickly assess the diet in several French population subgroups, and standardize dietary data collection at a national level. We used data from over 50 000 women in the prospective E3N-EPIC cohort study and considered fruit and vegetable consumption as a proxy for overall diet quality. Compared with healthy and non-cancer women, an increase in fruit and vegetable consumption was only observed in women who had an advanced stage of breast cancer (stages II-III-IV). This increase was also only observed in certain socioeconomic groups (e.g. women with high level of education and women living in the South of France). A short food frequency questionnaire (SFFQ) was also developed, both a paper and online version, to easily and quickly assess diet. Both versions were validated in a sample of 127 patients with chronic kidney disease and a sample of 92 adults selected among the general population, respectively. Our results help to understand the complex influence of the socioeconomic environment on the evolution of the diet among patients who had cancer. Further studies are required to better understand the factors that prevent cancer survivors from the adoption of healthy dietary patterns. Dietary guidelines should adapt to the socioeconomic environment of individuals, in order to reduce socioeconomic inequities in diet and cancer. Finally, within the framework of the present study, a standardized, validated, short and modern tool has been developed to quickly assess diet in French clinical and epidemiological studies. Diet and dietary patterns will therefore be comparable between several French population subgroups.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A adoção do plano dietético Dietary Approaches to Stop Hypertension (DASH) tem sido enfatizado na população hipertensa como uma importante estratégia no controle dos níveis pressóricos elevados. O objetivo deste estudo foi analisar o consumo alimentar de macro e micronutrientes em pacientes hipertensos, em especial do sódio, cálcio, potássio e magnésio, e comparar com as recomendações dietéticas contidas no plano DASH. Estudo transversal envolvendo uma amostra de conveniência composta por 113 hipertensos entre 40 e 69 anos. A medida da pressão arterial (PA) foi determinada com aparelho eletrônico devidamente calibrado e a avaliação dietética obtida pelo questionário de freqüência do consumo alimentar. Os alimentos ingeridos foram convertidos em porções e distribuídos em diferentes grupos alimentares. A faixa de porções recomendadas pelo plano DASH foi determinada com base na média das necessidades energéticas desta amostra permitindo assim uma posterior comparação com o hábito alimentar dos hipertensos, utilizando um escore de pontos com pontuação máxima de 9 pontos. A amostra foi dividida em três grupos: grupo B que obteve 2,5 a 4,0 pontos (n=34; 30%), grupo M entre 4,5 a 5,0 pontos (n=43; 38%) e grupo A que obteve 5,5 a 8,0 pontos (n=36; 32%). Não foram observadas diferenças significativas na média da PA sistólica (14024 vs 13823 vs 13515 mmHg) e diastólica (8617 vs 8813 vs 8410 mmHg). Apesar do grupo A consumir mais proteínas e gordura monoinsaturada, foi detectado um excesso pronunciado na ingestão de gordura saturada, colesterol e das calorias totais, por este grupo de pacientes. No que tange a ingestão dos micronutrientes, o grupo A apresentou consumo significativamente maior de cálcio, potássio e magnésio, refletido pela maior ingestão de vegetais e frutas em comparação aos grupos B e M. A média de ingestão do sódio intrínseco foi significativamente maior no grupo A (4,12,0 vs 3,11,1 vs 2,71,1 g/dia). Foram detectadas, apenas no grupo A, correlações entre PA sistólica e o percentual de proteína (r = -0,5; p=0,002) e PA sistólica e o percentual de carboidrato (r = 0,4; p=0,02). Apenas um terço dos hipertensos avaliados apresentaram padrão alimentar mais concordante com o plano DASH e com maior ingestão de proteínas, gordura monoinsaturada, fibras, cálcio, potássio e magnésio. Entretanto, o consumo mais elevado de sódio, gordura saturada, colesterol e das calorias totais por este grupo de pacientes poderia restringir uma maior queda dos níveis pressóricos elevados. / The adoption of the Dietary Approaches to Stop Hypertension (DASH) plan has been emphasized in the hypertension population as an important strategy in the control of the raised blood pressure (BP). The objective of this study was to analyze the alimentary consumption of macro and micronutrients in hypertensive patients, especially of sodium, calcium, potassium and magnesium, and to compare with the dietary recommendations contained in DASH plan. Transversal study was conducted in a convenience sample of 113 hypertensive patients, between 40 and 69 years. The BP measurement was determined with calibrated electronic device and the dietary assessment was performed trough the semiquantitative food frequency questionnaire. For comparison with DASH plan, ingested foods were converted into portions and the magnitude of the portions recommended for DASH plan was determined on the basis of the mean energy requirements of this sample. Thereafter, cut-off points were established for food groups, the maximum number of points that a patient could reach was 9. The sample was divided in tertils: Group L with 2.5 4.0 points (n=34; 30%), Group I with 4.5 5.0 points (n=43; 38%) and Group H with 5.5 8.0 points (n=36; 32%). Systolic and diastolic BP were not significantly different among the groups (14024 vs 13823 vs 13515 mmHg/ 8617 vs 8813 vs 8410 mmHg). Group H consumed more proteins and monoinsaturated fat, a pronounced excess in the saturated fat, cholesterol and total calories intake was also detected in this group of patients. Regarding micronutrients intake, group H presented significantly higher consumption of calcium, potassium and magnesium, reflected for higher vegetable and fruits intake in comparison to the groups L and I. The average of intrinsic sodium intake was significantly higher in the group H (4.12.0 vs 3.11.1 vs 2.71.1 g/day). Negative correlation between the systolic BP and dietary protein percentage (r=-0.5, p=0.002) and a positive correlation between the systolic BP and the carbohydrate percentage (r=0.4, p=0.02) was verified only in group H. The present study showed that only one third of the hypertensive patients presented alimentary pattern more consistent with DASH plan, showing greater intake of protein, monounsaturated fat, fiber, calcium, potassium and magnesium. However, pronounced sodium, saturated fat and cholesterol intake and excess of total calories in these hypertensive patients could restrict a greater control of BP.
