Dietary patterns associated with anthropometric indicators of abdominal fat in adults

This study aimed to identify dietary patterns and assess their association with abdominal fat. A cross-sectional study was conducted in the Central West Region of Brazil with a probabilistic sample of 208 adults of both sexes. Data on food intake was obtained using a food frequency questionnaire and factor analysis (principal components) was conducted to identify dietary patterns. Waist circumference (WC) and waist-to-hip ratio (WHR) were used to assess abdominal fat. The association between dietary patterns and body fat distribution was examined using multiple linear regression analysis adjusted for confounders. Three dietary patterns were identified: Western, regional traditional, and prudent. A positive association was found between the Western pattern and WC (p = 0.04) and WHR (p = 0.001) and between the regional traditional pattern and WHR (p = 0.05) among women. A slight association was also found between the latter pattern and WC (p = 0.07) also among women. An association was found between the Western and regional traditional dietary patterns and a larger concentration of abdominal fat among women.Este estudo teve o objetivo identificar padroes alimentares e analisar a associacao com a adiposidade abdominal. Estudo transversal, realizado na Regiao Centro-Oeste do Brasil, com amostra probabilistica de 208 adultos, de ambos os sexos. O consumo alimentar foi obtido por questionario de frequencia alimentar e aplicada analise fatorial (componentes principais) para identificar padroes alimentares. A circunferencia da cintura (CC) e a relacao cintura quadril (RCQ) foram indicadores de adiposidade abdominal. A associacao dos padroes alimentares com adiposidade abdominal foi analisada em modelos de regressao linear multipla ajustados por fatores de confusao. Identificaram-se tres padroes alimentares: ocidental, tradicional regional e prudente. O padrao ocidental associou-se positivamente com CC (p = 0,04) e RCQ (p = 0,001) e o padrao tradicional regional associou-se tambem com RCQ (p = 0,05), e marginal a associacao com a CC (p = 0,07) somente em mulheres. Os padroes ocidental e tradicional regional associaram a maior adiposidade abdominal em mulheres.

Meal habits and anthropometric indicators in adolescents from public and private schools of the metropolitan region of Rio de Janeiro

Objective To describe meal consumption habits and assess their associations with anthropometric indicators.

Skipping breakfast and associated factors among Brazilian adolescents

Objective To analyze the prevalence and factors associated with breakfast skipping among adolescents. Methods Cross-sectional study, with adolescents aged 10–17 years, evaluated between 2009 and 2011, belonging to a cohort study in the Central-West region of Brazil. Breakfast skipping was considered as not having breakfast every day. Demographic, socioeconomic, and lifestyle factors were evaluated through a questionnaire. Anthropometric assessment included measurement of weight and height, which were used to classify weight status using body mass index. Poisson regression was used to assess the association of breakfast skipping with demographic and socioeconomic variables, lifestyle factors, and weight status. Results Among 1,716 Brazilian adolescents evaluated, 36.2% reported not consuming breakfast every day, with the highest prevalence among girls (p=0.03). After adjusting for age and economic class, breakfast skipping was associated with not consuming breakfast with parents and morning shift at school, in both genders, and with obesity only in boys. Lifestyle factors such as alcohol consumption, physical activity, diet quality, and smoking were not associated with skipping breakfast.

Viabilidade do uso de pergunta simplificada na avaliação da qualidade da dieta de adolescentes

Resumo Analisou-se a aplicabilidade de pergunta simplificada na avaliacao da qualidade da alimentacao de adolescentes em estudo transversal de base escolar, com estudantes do ensino medio. A autopercepcao da qualidade da alimentacao foi obtida ao inquirir o participante se considerava sua alimentacao muito boa, boa, regular ou ruim. Foram avaliados os habitos de refeicoes e o consumo alimentar por meio de questionario de frequencia de consumo. Estimou-se o Indice de Qualidade da Dieta-Revisado (IQD-R) e foram identificados tres padroes alimentares com o uso de analise fatorial. A autopercepcao da qualidade da alimentacao como “boa” foi referida por 56% dos adolescentes, associando-se ao consumo regular de frutas, hortalicas, das refeicoes principais e escores elevados do IQD-R. Contudo, o consumo de alimentos deleterios a saude nao foi percebido como caracteristica que afeta a qualidade da dieta. A pergunta avaliada apresentou sensibilidade de 28% para detectar dietas de boa qualidade e especificidade de 79% para identificar dietas de baixa qualidade nutricional. O uso de pergunta simplificada para avaliar habitos alimentares de adolescentes e limitada, dado que o consumo de alimentos com alto teor de gordura, acucar e sodio nao foi reconhecido como indicador de dieta de baixa qualidade.
