Menopause, Rurality, And Obesity in Rural African American Women

In the US, one in every eight deaths is due to an obesity-related chronic health condition (ORCHC). More than half of African American women (AAW) 20 years old or older are obese or morbidly obese, as are 63% of menopausal AAW. Many have ORCHC that increase their morbidity and mortality and increase health care costs. In 2013, 42.6 percent of AAs living in South Carolina (SC) were obese. The purpose of this cross-sectional study was to identify the cognitive, behavioral, biological, and demographic factors that influence health outcomes (BMI, and ORCHC) of AAW living in rural SC. A sample of 200 AAW (50 in each of the 4 groups of rurality by menopausal status), 18-64 years, completed the: Menopausal Rating Scale (symptoms); Body Image Assessment for Obesity (self-perception of body); Mental Health Inventory; Block Food Frequency Questionnaire; Eating Behaviors and Chronic Conditions, Traditional Food Habits, and Food Preparation Technique questionnaires – and measures for Body Mass Index. Most rural, and premenopausal AAW were single and not living with a partner. Premenopausal women had significantly higher educational levels. Sixty percent of AAW had between 1 and 5 ORCHC. Most AAW used salt based seasonings, ate deep fried foods 1 to 3 times a week, and ate outside the home 1 to 3 times a month. Few AAW knew the correct daily serving for grains and dairy, and most consumed less than the recommended daily serving of fruits, vegetables and dairy. Morbidly obese AAW used more traditional food preparation techniques than obese and normal-weight AAW. Rural, and menopausal AAW had significantly higher morbid obesity levels, consumed larger portions of meats and vegetables, and reported more body image dissatisfaction than very rural AAW, and premenopausal AAW, respectively. Controlling for socioeconomic factors the relationships between perceptions of body images, psychological distress, and psychological wellbeing remained significant for numbers of ORCHC

An investigation of sugar-sweetened beverage consumption among Canadian youth

Background: Consumption of sugar-sweetened beverages (SSBs) is an important public health problem in Canada, especially among adolescents. Estimates show that rates of SSB consumption are particularly high in the northern territories, especially in Nunavut. This is concerning given that regular SSB consumption is associated with obesity, diabetes and tooth decay, among other health concerns. Objectives: This thesis has two objectives. The first is to describe SSB consumption patterns among adolescents from Nunavut specifically, all three territories combined and the provinces.The second is to determine the association between individual and cumulative school food programs and SSB consumption. Methods: Data were obtained from the Health Behaviour in School-aged Children study (HBSC); a cross-sectional survey of Canadian youth in grades 6-10. All frequencies for food and beverage consumption were obtained from a 7-day food frequency questionnaire. SSB consumption consisted of a composite measure including soft drinks, sports drinks and energy drinks. The types of school food programs were obtained from an administrative questionnaire filled out by each school’s Principal or delegate. Multilevel multivariate Poisson regression models were used to examine the associations between school food programs and SSB consumption. Results: Youth from Nunavut consumed the most SSBs (53.1% in 2010 and 55.0% in 2014 were daily consumers), followed by youth from the territories (31.1% in 2010 and 27.0% in 2014), then youth from the provinces (24.3% in 2010 and 19.1% in 2014). No significant relationships were found between school food programs and daily SSB consumption. Two school food programs were weakly associated with weekly SSB consumption: nutrition month activities (RR=0.93,CI=0.89, 0.98) and healthy options in the snack bar (RR=1.07, CI=1.01, 1.14). Conclusions:Rates of SSB consumption were highest among Nunavummiut youth followed by youth from all three territories combined and then the provinces. Little association was found between school food programs and SSB consumption among Canadian youth in grades 6-10. These findings point to the need for examining other determinants and potential areas for intervention, for reducing SSB consumption among Canadian youth, particularly in high consumer sub-populations.

Effect of a Mediterranean Diet Intervention on Dietary Glycemic Load and Dietary Glycemic Index: The PREDIMED Study

[EN]To compare the one year effect of two dietary interventions with MeDiet on GL and GI in the PREDIMED trial. Methods. Participants were older subjects at high risk for cardiovascular disease. This analysis included 2866 nondiabetic subjects. Diet was assessed with a validated 137-item food frequency questionnaire (FFQ). The GI of each FFQ item was assigned by a 5-step methodology using the International Tables of GI and GL Values. Generalized linear models were fitted to assess the relationship between the intervention group and dietary GL and GI at one year of follow-up, using control group as reference.

Comportamentos alimentares e saúde oral em voleibolistas

Introdução e objectivos: A saúde oral em atletas é parte essencial para a saúde geral, sendo um factor determinante para a qualidade de vida e desempenho desportivo. Logo, um bom estado de saúde só existirá se a cavidade oral se encontrar ausente de patologias. Os desequilíbrios nutricionais possuem efeitos sobre a cavidade oral, condicionando assim a qualidade de vida e desempenho do atleta. Desta forma, o excesso de ingestão de alguns alimentos podem ser factores de risco para a saúde, tendo conta em que, a etiologia da cárie dentária está relacionada com a ação de microorganismos orais que produzem ácidos orgânicos, a partir do metabolismo dos hidratos de carbono. O objectivo deste estudo foi avaliar a saúde oral bem como os hábitos alimentares e o uso de protetores bucais durante a prática desportiva. Participantes e Métodos: Foram observados 55 atletas de voleibol entre os 15 e 18 anos de ambos os géneros, do clube de voleibol Academia José Moreira e Leixões. Tratou-se de um estudo transversal, no qual foi realizado exame clínico intraoral (índice de cárie CPOd, indice de erosão dentária BEWE) e preenchimento de questinário, em que os indivíduos foram caracterizados em 5 componentes: dados sociodemográficos (idade, peso e estatura), dados sobre perceção de saúde, dados sobre comportamentos de saúde oral, dados sobre prática desportiva e dados sobre comportamentos alimentares (questionário semi-quantitativo de frequência alimentar). A análise estatística descritiva e inferencial dos dados recolhidos foi realizada com o auxílio do programa informático SPSS, versão 23.0. Resultados: Os hábitos de saúde oral não são os mais adequados e a percentagem de atletas que visita o médico dentista é elevada para “só quando tem dores” ou “ocasionalmente”. A média do CPOD geral foi de 4,22 ± 4,55. Não houve diferenças estatisticamente significativas (p>0,05) entre o CPOD geral e o IMC. Nenhum dos atletas usa protetor bucal durante a prática desportiva. Os alimentos mais consumidos foram a carne, fruta, leite, peixe e, biscoitos, bolos e bolachas; e os menos consumidos foram as bebidas alcoólicas, mel ou compotas e café. Conclusão: Os hábitos de higiene oral são um melhor indicador do que o IMC para a presença de cárie. Não há relação direta entre índice CPOD e IMC. Seria importante prestar mais informação sobre vantagens do uso de protetores bucais junto dos atletas e de treinadores bem como, esclarecer que a consistência e as propriedades sensoriais ligadas à textura e à consistência dos alimentos na superfície dentária interferem com a cárie.

Alcohol consumption and Mediterranean Diet adherence among health science students in Spain: the DiSA-UMH Study

Objective: To describe the association between consumption of different alcoholic beverages and adherence to the Mediterranean diet. Methods: A cross-sectional analysis was conducted of the baseline data of the DiSA-UMH study, an ongoing cohort study with Spanish health science students (n = 1098) aged 17-35 years. Dietary information was collected by a validated 84-item food frequency questionnaire. Participants were grouped into non-drinkers, exclusive beer and/or wine drinkers and drinkers of all types of alcoholic beverages. Mediterranean diet adherence was determined by using a modification of the relative Mediterranean Diet Score (rMED; score range: 0-16) according to consumption of 8 dietary components. We performed multiple linear and multinomial regression analyses. Results: The mean alcohol consumption was 4.3 g/day (SD: 6.1). A total of 19.5%, 18.9% and 61.6% of the participants were non-drinkers, exclusive beer and/or wine drinkers and drinkers of all types of alcoholic beverages, respectively. Participants who consumed beer and/or wine exclusively had higher rMED scores than non-drinkers (β: 0.76, 95%CI: 0.25-1.27). Drinkers of all types of alcoholic beverages had similar rMED scores to non-drinkers. Non-drinkers consumed less fish and more meat, whereas drinkers of all types of alcoholic beverages consumed fewer fruits, vegetables and more meat than exclusive beer and/or wine drinkers. Conclusions: The overall alcohol consumption among the students in our study was low-to-moderate. Exclusive beer and/or wine drinkers differed regarding the Mediterranean diet pattern from non-drinkers and drinkers of all types of alcohol. These results show the need to properly adjust for diet in studies of the effects of alcohol consumption.

Calcium Intake, Major Dietary Sources and Bone Health Indicators in Iranian Primary School Children

Background: Adequate calcium intake may have a crucial role with regards to prevention of many chronic diseases, including hypertension, hypercholesterolemia, different types of cancer, obesity and osteoporosis. In children, sufficient calcium intake is especially important to support the accelerated growth spurt during the preteen and teenage years and to increase bone mineral mass to lay the foundation for older age. Objectives: This study aimed to assess daily calcium intake in school-age children to ensure whether they fulfill the FGP dairy serving recommendations, the recommended levels of daily calcium intake and to assess the relationship between dietary calcium intake and major bone health indicators. Patients and Methods: A total of 501 Iranian school-age children were randomly selected. Calcium intake was assessed using a semi-quantitative food frequency questionnaire. Bone health indicators were also assessed. Results: Dairy products contributed to 69.3% of the total calcium intake of the children. Daily adequate intake of calcium was achieved by 17.8% of children. Only 29.8% met the Food guide pyramid recommendations for dairy intake. Dietary calcium intake was not significantly correlated with serum calcium and other selected biochemical indicators of bone health. Conclusions: The need for planning appropriate nutrition strategies for overcoming inadequate calcium intake in school age children in the city of Tehran is inevitable.

Comportamento alimentar e excesso de peso em profissionais do sector da saúde

A prevalência da obesidade está a aumentar nos países desenvolvidos e Portugal não é excepção. O presente trabalho teve como principal objectivo caracterizar a situação relativamente aos parâmetros antropométricos e hábitos alimentares de várias categorias profissionais do sector da saúde de uma instituição hospitalar do distrito de Lisboa. Com efeito, verificou-se que existem diferenças ao nível do Índice de Massa Corporal (IMC), da massa gorda e muscular e do perímetro de cintura entre as profissões estudadas (assistentes operacionais, enfermeiros, médicos e técnicos de diagnóstico e terapêutica). De acordo com a classificação do IMC, o grupo estudado situou-se no cut-off superior do ‘peso normal’ (IMC de 24,9 kg/m2). A obesidade esteve presente em 29% dos assistentes operacionais, 9% nos médicos e 5% nos enfermeiros e técnicos de diagnóstico e terapêutica. Também se observaram diferenças entre os géneros feminino e masculino, já que neste último o IMC foi de 26,5 kg/m2 e no primeiro foi de 24,6 kg/m2. Quanto aos hábitos alimentares, através do questionário de frequência alimentar (QFA) e após comparar com as recomendações da pirâmide dos alimentos mediterrânica e com a roda dos alimentos, foi notório o desvio do padrão alimentar face ao que é preconizado por estas representações. Assim, a maioria dos indivíduos não ingere produtos lácteos, pão, cereais e derivados com a frequência que seria adequada. Também se observaram diferenças no reporte de ingestão dos mesmos alimentos entre as categorias profissionais, salientando que todas estas apresentam padrões de ingestão desviantes das recomendações defendidas pela pirâmide dos alimentos mediterrânica e pela roda dos alimentos. Na sociedade actual, o local de trabalho é cada vez mais obesogénico devido quer à mudança na natureza do trabalho, quer às condições em que este decorre. Face aos resultados obtidos foi elaborado um plano de intervenção sócio- organizacional que visa promover hábitos alimentares e estilos de vida saudáveis. /ABSTRACT: Obesity prevalence is increasing all over developed countries, and Portugal is no exception. The present study had as major objective to describe the situation relative to anthropometric measures and dietary habits of several job strains operating in the health sector of a Lisbon district’s central hospital. Indeed, it has been verified that there are differences as concern to Body Mass Index (BMI), fat and muscle mass and waist circumference among the job strains studied (operational assistants, nurses, physicians and diagnostic and therapeutic technicians). According to BMI classification, the sample showed to be lined up with the superior BMI cut-off value for “normal weight” (BMI of 24,9 kg/m2). Obesity was present in 29% of operational assistants, 9% in physicians, 5% in nurses and diagnostic and therapeutic technicians. There were differences in both feminine and masculine genders, as in the latter the BMI was 26,5 kg/m2 and in the first, 24,6 kg/m2. As concern to dietary habits, through the application of the food frequency questionnaire (FFQ), after comparing with mediterranean food pyramid and wheel of foods it was notorious the deviation of dietary habits from these representations. Thus, most individuals do not consume dairy products, bread, cereals and derivates with an appropriate eating frequency. There were also differences in eating reporting of the same foods between job strains, focusing that all of these show eating patterns that deviates from the recommendations argued by mediterranean food pyramid and wheel of foods. In the present societies, workplace appears to be obesogenic due to the changes in labour’s nature and to the conditions that this one takes place. Towards the results obtained, it was developed a social and organizational intervention which entails to promote healthy eating habits and lifestyles.

AN ANALYSIS OF THE RELATIVE INFLUENCE OF RACE, INCOME, EDUCATION, AND FOOD STAMP PROGRAM PARTICIPATION/NONPARTICIPATION ON THE FOOD AND NUTRIENT CONSUMPTION OF A NORTH FLORIDA URBAN CLINIC POPULATION IN CONJUNCTION WITH A SURVEY OF NUTRITION RELATED HABITS AND ATTITUDES

The relative influence of race, income, education, and Food Stamp Program participation/nonparticipation on the food and nutrient intake of 102 fecund women ages 18-45 years in a Florida urban clinic population was assessed using the technique of multiple regression analysis. Study subgroups were defined by race and Food Stamp Program participation status. Education was found to have the greatest influence on food and nutrient intake. Race was the next most influential factor followed in order by Food Stamp Program participation and income. The combined effect of the four independent variables explained no more than 19 percent of the variance for any of the food and nutrient intake variables. This would indicate that a more complex model of influences is needed if variations in food and nutrient intake are to be fully explained.^ A socioeconomic questionnaire was administered to investigate other factors of influence. The influence of the mother, frequency and type of restaurant dining, and perceptions of food intake and weight were found to be factors deserving further study.^ Dietary data were collected using the 24-hour recall and food frequency checklist. Descriptive dietary findings indicated that iron and calcium were nutrients where adequacy was of concern for all study subgroups. White Food Stamp Program participants had the greatest number of mean nutrient intake values falling below the 1980 Recommended Dietary Allowances (RDAs). When Food Stamp Program participants were contrasted to nonparticipants, mean intakes of six nutrients (kilocalories, calcium, iron, vitamin A, thiamin, and riboflavin) were below the 1980 RDA compared to five mean nutrient intakes (kilocalories, calcium, iron, thiamin and riboflavin) for the nonparticipants. Use of the Index of Nutritional Quality (INQ), however, revealed that the quality of the diet of Food Stamp Program participants per 1000 kilocalories was adequate with exception of calcium and iron. Intakes of these nutrients were also not adequate on a 1000 kilocalorie basis for the nonparticipant group. When mean nutrient intakes of the groups were compared using Student's t-test oleicacid intake was the only significant difference found. Being a nonparticipant in the Food Stamp Program was found to be associated with more frequent consumption of cookies, sweet rolls, doughnuts, and honey. The findings of this study contradict the negative image of the Food Stamp Program participant and emphasize the importance of education. ^

Intake of isoflavone and lignan phytoestrogens and associated demographic and lifestyle factors in older Australian women

The purpose was to determine intake of phytoestrogens in a sample of older Australian women, and to investigate associated lifestyle factors. Subjects were an age-stratified sample of 511 women aged 40-80 y, randomly selected from the electoral roll and participating in the Longitudinal Assessment of Ageing in Women at the Royal Brisbane and Women’s Hospital. A cross-sectional study was conducted to assess isoflavone and lignan intake over the past month from food and supplements using a 112-item phytoestrogen frequency questionnaire. Data were also collected on nutrient intakes, physical activity, smoking, alcohol, non-prescription supplements, hormone therapy, education and occupation. Logistic regression was used to evaluate associations between demographic and lifestyle variables and soy/linseed consumption while controlling for age. Isoflavone intakes were significantly higher in the younger compared to older age groups (p<0.001); there were no age-related differences in lignan intake. Forty-five percent of women consumed at least one serve of a soy and/or linseed item and were defined as a soy/linseed consumer. Median (range) intakes by consumers for isoflavones and lignans (3.9 (0-172) mg/d and 2.4 (0.1-33) mg/d) were higher than intakes by non-consumers (0.004 (0-2.6) mg/d and 1.57 (0.44-4.7) mg/d), respectively (p<0.001). Consumers had higher intakes of dietary fibre (p=0.003), energy (p=0.04) and polyunsaturated fat (p=0.004), and higher levels of physical activity (p=0.006), socio-economic position (p<0.001), education (p<0.001) and supplement use (p<0.001). Women who consumed soy or linseed foods differed in lifestyle and demographic characteristics suggesting these factors should be considered when investigating associations with chronic disease outcomes.

Prevalência de obesidade infanto-juvenil : associação com os hábitos alimentares, actividade física e comportamentos sedentários dos adolescentes escolarizados de Portugal Conti

RESUMO Nos países industrializados observam-se elevadas prevalências de pré- obesidade e obesidade em jovens e adolescentes, com consequências negativas para a saúde. A obesidade é apontada como o distúrbio nutricional mais frequente em crianças e adolescentes nos países desenvolvidos e é resultado da acumulação excessiva ou anormal de gordura no tecido adiposo. Segundo a I.O.T.F. considera- se que uma criança tem pré-obesidade quando o seu percentil de I.M.C. está entre o p88 e p99 para as raparigas e entre o p90 e o p99 para os rapazes. Considerase que tem obesidade quando o percentil de I.M.C. é superior ao p99, para ambos os sexos. A prevalência de pré-obesidade e obesidade em crianças e adolescentes tem vindo a aumentar a nível mundial a um ritmo alarmante, sobretudo nos países desenvolvidos e em alguns segmentos de países em desenvolvimento. Estudos demonstram que a obesidade em crianças e adolescentes se encontra fortemente correlacionada com o aumento da morbilidade e mortalidade, reflectindo-se numa variedade de situações patológicas com risco de persistência no adulto. Dada a sua extrema importância em termos de Saúde Pública, as tendências para a pré- obesidade e obesidade em crianças e adolescentes devem ser monitorizadas com especial atenção. Os hábitos alimentares e o gasto energético são factores que influenciam a obesidade e o seu controlo. Há estudos que concluem que existe uma associação directa entre estes factos e a presença de obesidade e outros apresentam conclusões contrárias. Pretendeu-se determinar a prevalência de excesso de peso (pré-obesidade e obesidade) infantojuvenil em Portugal e associá-la com os hábitos alimentares, actividade física e comportamentos sedentários dos adolescentes. A população em estudo é todos os adolescentes, de ambos os sexos, que frequentam o ensino básico (2º e 3º ciclos) e secundário oficial de Portugal Continental (n=5708). Todos os elementos em estudos foram avaliados antropometricamente (peso e altura) e responderam a um questionário de hábitos alimentares e frequência alimentar, actividade física e comportamentos sedentários. Como resultados do estudo verificou-se que a prevalência de pré- obesidade infanto-juvenil em Portugal é de 22,6% e a prevalência de obesidade de 7,8%. Quer a obesidade quer a pré-obesidade apresentam indicadores superiores nos rapazes (p=0,01) e nos adolescentes mais jovens (p=0,00). Em relação aos hábitos alimentares estudados é de referir que a frequência de consumo de refeições fora de casa é muito similar entre o grupo normoponderal e o grupo com excesso de peso sendo a refeição da ceia consumida por um número muito superior de adolescentes normoponderais comparativamente com os que apresentam excesso de peso (p=0,01). Em relação à ingestão de determinados alimentos ou grupos alimentícios, verificou-se que, regra geral, o consumo de alimentos de características nutricionais de baixa qualidade (gordura saturada, sal e açucares simples) era superior no grupo normoponderal comparativamente ao grupo com excesso de peso (refrigerantes, snacks, fast-food, cereais açucarados, sobremesas doces) (p<0,05). Em relação à actividade física, o número de horas semanais de actividade física diminui do grupo normoponderal para o grupo com excesso de peso. Dentro do grupo com excesso de peso, os obesos apresentam ainda uma média inferior em relação aos pré-obesos. Poderemos afirmar que quanto maior o índice de actividade física menor o percentil de I.M.C., mostrando-se assim a actividade física como um factor protector de um peso saudável (p<0,05). Quando solicitado que caracterizassem o estilo de vida e a habilidade desportiva, verificou-se que nos grupos com excesso de peso se caracterizavam em indicadores mais baixos do que os normoponderais (p<0,05). No que diz respeito aos comportamentos sedentários, verifica-se que são mais prevalentes nos grupos com excesso de peso do que no grupo normoponderal (p<0,05). Em conclusão, os resultados da prevalência de obesidade obtidos assemelham-se aos resultados obtidos noutros estudos, constituindo um dado revelador de uma situação bastante preocupante em termos de Saúde Pública. Em relação aos hábitos alimentares as diferenças não são significativas entre os diferentes grupos (normoponderal, pré-obesidade e obesidade). A actividade física apresentou-se como um factor protector do aumento de peso com uma associação directa com o estado nutricional (I.M.C.). Verificou-se que os adolescentes em Portugal que apresentavam indicadores mais elevados de actividade física eram aqueles que se encontravam com peso normal. Os comportamentos sedentários apresentaram-se como um factor propício ao desenvolvimento do excesso de peso estando directamente relacionados com o percentil de I.M.C. Os comportamentos sedentários mais frequentes são o visionamento televisivo e o computador/internet. Assim, poder-se-á fundamentar a necessidade de medidas interventivas a este nível com o intuito de controlar os indicadores encontrados. ABSTRACT In the industrialized countries high prevalences of pre-obesity and obesity are observed in youngsters and adolescents, with negative health consequences. Obesity is pointed as the most frequent nutritional disturbance in children and adolescents in developed countries and results from the excessive or abnormal accumulation of fat in the adipose tissue. According to the IOTF a child is pre-obese when the BMI percentile is between p88 and p99 for girls and between p90 and p99 for boys. Obesity is considered when the BMI percentile is above p99 for both sexes. The prevalence of pre-obesity and obesity in children and adolescents has been rising alarmingly worldwide, especially in developed countries and some segments of developing countries. Studies indicate that obesity in children and adolescents is strongly associated with increased morbidity and mortality resulting in a variety of pathological situations with risk of persistence in adulthood. Given its major Public Health importance, pre-obesity and obesity trends in children and adolescents should be monitored with special attention. Eating habits and energy expenditure are factors that influence obesity and its control. Some studies conclude that there is a direct association between these factors and the presence of obesity and others present opposite conclusions. It was intended to determine the prevalence of overweight (pre-obesity and obesity) in children and youth in Portugal and to associate it with eating habits, physical activity and sedentary behaviors of adolescents. The population in study is constituted by all adolescents of both sexes that attend basic (2nd and 3rd grade) and secondary official education of continental Portugal (n=5708). All participants in study were anthropometrically evaluated (weight and height) and answered a questionnaire of eating habits and food frequency, physical activity and sedentary behaviors. The study results indicate a prevalence of pre-obesity in children and youth in Portugal of 22.6% and a prevalence of obesity of 7.8%. Both obesity and pre-obesity present higher indicators in boys (p=0.01) and younger adolescents (p=0.00). In relation to the studied eating habits it should be noted that the frequency of consumption of meals away from home is very similar between the normal weight group and the overweight group. Moreover, the supper meal is consumed by a much larger number of normal weight adolescents as compared to the ones with overweight (p=0.01). Regarding the intake of certain foods or food groups, it was found that, in general, the consumption of foods with characteristics of low nutritional quality (saturated fat, salt and simple sugars) was higher in the normoponderal group compared with the overweight group (soft drinks, snacks, fast-food, sugary cereals, desserts) (p<0.05). In respect to physical activity, the number of weekly hours of physical activity decreases from the normoponderal group to the group with overweight. Within the group with overweight, obese subjects also present a lower average than pre-obese subjects. As we can affirm that the higher the physical activity index the lower the BMI percentile, physical activity appears as a protective factor for a healthy weight (p<0.05). When they were asked to characterize their lifestyle and sports ability, it was found that overweight groups characterized themselves with lower indicators than the normoponderal group (p<0.05). Regarding sedentary behaviors, it appears that they were more prevalent in groups with overweight than in the normoponderal group (p<0.05). In conclusion, the results of the obesity prevalence attained are similar to the results obtained in other studies, revealing a very worrying situation in terms of Public Health. In relation to the eating habits there were no significant differences between the groups (normoponderal, pre-obesity and obesity). Physical activity appears as a protective factor from weight gain with a direct association with nutritional status (BMI). It was found that young people in Portugal who had the highest indicators of physical activity were those who presented normal weight. The sedentary behaviors were presented as a factor conducive to the development of overweight being directly related to the BMI percentile. The most frequent sedentary behaviors were television viewing and computer/internet

Dietary supplement use and its impact on nutritional adequacy for British Columbia and Manitoba First Nations adults living on reserve.

Contexte: L'utilisation de suppléments alimentaires est répandue chez les populations américaines et canadiennes en général, mais on en sait peu sur la consommation de suppléments alimentaires dans la population autochtone canadienne. Objectif: L'objectif général de cette étude est de prendre en compte l'utilisation de suppléments alimentaires dans l'évaluation nutritionnelle des apports alimentaires des adultes des Premières nations vivant dans les réserves en Colombie-Britannique et Manitoba. Conception: Les données ont été recueillies par l’étude ‘First Nations Food, Nutrition, and Environment Study’ de 1103 (Colombie-Britannique) et 706 (Manitoba) adultes des Premières Nations âgés de 19 à 70 ans. L'étude a utilisé un rappel alimentaire des dernières 24 heures (avec un deuxième rappel pour un sous-échantillon) pour évaluer la diète alimentaire. L'utilisation de suppléments alimentaires et des antiacides ont été recueillis par un questionnaire de fréquence. En utilisant le logiciel SIDE pour tenir compte des variations intra-individuelles dans la prise alimentaire et la technique du bootstrap pour obtenir des estimations représentatives des différentes régions, l'utilisation de suppléments de la vitamine A, D, C et de calcium ont été intégrées aux estimations de la consommation alimentaire. Résultats: Environ 30% des adultes des Premières Nations de la Colombie-Britannique et seulement 13,2% des adultes des Premières Nations du Manitoba âgés entre 19-70 ans vivant dans les réserves ont déclaré utiliser au moins un supplément alimentaire durant les 30 jours précédents. Lors de l'examen des nutriments d'intérêt, un plus faible pourcentage de la population en a fait usage, de 14,8 à 18,5% en Colombie-Britannique et de 4,9 à 8% de la population du Manitoba. La prévalence de l'usage de tout supplément alimentaire était plus élevée chez les femmes que chez les hommes dans tous les groupes d'âge et augmente avec l'âge dans les deux sexes. La plus forte prévalence d'un apport insuffisant provenant de la nourriture a été observée pour la vitamine D et le calcium en Colombie-Britannique et Manitoba, variant de 75 à 100%, et de la vitamine A dans le Manitoba (73-96%). Après avoir examiné l'utilisation de suppléments alimentaires, plus des trois quarts des participants n’ont toujours pas réussi à répondre au besoin moyen estimatif pour ces nutriments. La vitamine C est l'oligo-élément avec le plus faible pourcentage sous le besoin moyen estimatif (avec au sans suppléments) pour la Colombie-Britannique et le Manitoba. Conclusion: La majorité des adultes des Premières nations de la Colombie-Britannique et du Manitoba, même après prise en compte de l'utilisation de suppléments alimentaires, avaient des apports en vitamines A, D et des apports de calcium sous les niveaux recommandés. L'utilisation de compléments alimentaires n'a pas contribué de façon significative à l'apport total en nutriments sélectionnés sauf pour la vitamine C dans certains groupes d'âge.

Associação entre consumo alimentar e atividade física com a síndrome metabólica em mulheres na pós-menopausa

Post-menopause is characterized as the period beginning one year after the permanent cessation of menstrual cycles, which is typically related to medical disorders that, in association with Metabolic Syndrome (MS), represent a set of cardiovascular risk factors. Objective: To assess dietary intake and the prevalence of metabolic syndrome in postmenopausal women, according to the level of physical activity. Methods: The sample consisted of 82 women, evaluated in the Northern Zone of the city of Natal / RN who were participants in the Natal Active Program. People completed a Food Frequency Consumption Questionnaire (FFCQ) and were interviewed about physical activity. Anthropometric measurements and biochemical tests were used to diagnose MS (Metabolic Syndrome). Result: The active women consumed more protective foods (flaxseed, nuts, whole wheat bread, brown rice and olive oil) than inactive women. Risky foods (sugar, crackers, white bread, white rice, margarine and beef) were consumed more by the group of inactive women. The prevalence of MS was higher in inactive women (53.30%) than in physically active women (46.70%). Conclusion: Active post-menopausal women had a higher daily intake of protective foods in relation to cardiovascular disease, while the inactive post-menopausal women had higher intake of risky foods for such diseases
