          Abstract

          Objective: dietary pattern evaluation is often used in order to determine wheter a diet is healthy, as well as to predict the onset of diseases. This study aimed to identify dietary patterns, and to examine their associations with general (body mass index) and central (waist circumference and waist-to-hip ratio) obesity in community-living elderly in a Brazilian city. Methods: this cross-sectional study included 126 elderly subjects aged 60 or older (57.1% females and mean age 74.2 ± 6.46 years). Anthropometric variables, weight, height, waist (WC) and hip (HC) circumferences, were measured. Body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. Answers to a Food Frequency Questionnaire were interpreted by Principal Component Analysis in order to identify dietary patterns. Results: five dietary patterns were identified and named as prudent (fruit, vegetables and meat), sweets and fats (pastries, sugary foods, fatty foods, whole milk), typical Brazilian (fried eggs, cooked beans, beef, candy, string beans, fried cassava), Mediterranean (fruit, vegetables, olive oil and nuts) and traditional meal (rice and beans). Moderate and high adherences to the Mediterranean pattern were protective factors to general and central obesity (WHR). High adherence to prudent was also protective to central obesity (WC). Conclusion: adherences to the dietary patterns prudent and Mediterranean were protective factors to general and central obesity in elderly.

          Objetivo: a avaliação do padrão alimentar é muitas vezes usada para determinar se uma dieta é saudável, bem como para predizer o aparecimento de doenças. Este estudo teve como objetivo identificar padrões alimentares e analisar as suas associações com obesidade geral (índice de massa corporal) e central (circunferência da cintura e relação cintura-quadril) em idosos residentes em comunidade em uma cidade brasileira. Métodos: este estudo transversal incluiu 126 idosos com 60 anos ou mais de idade (57,1% do sexo feminino e média de idade 74,2 ± 6,46 anos). As variáveis antropométricas [peso, altura, circunferências da cintura (CC) e do quadril (CQ)] foram mensuradas. Foram calculados o índice de massa corporal (IMC) e relação cintura-quadril (RCQ). As respostas a um questionário de frequência alimentar foram interpretadas por Análise de Componentes Principais, a fim de identificar os padrões alimentares. Resultados: cinco padrões alimentares foram identificados e nomeados como prudente (frutas, legumes e car-ne), doces e gorduras (alimentos de pastelaria, doces, alimentos gordurosos, leite integral), padrão tipicamente brasileiro (ovos fritos, feijão cozido, carne, caramelo, vagens, mandioca frita), Mediterrâneo (frutas, legumes, azeite de oliva e nozes) e tradicional (arroz e feijão). Adesões moderada e alta ao padrão Mediterrâneo foram fatores de proteção para obesidade geral e central (RCQ). Alta adesão ao padrão prudente também foi protetor contra a obesidade central (CC). Conclusão: adesões aos padrões alimentares prudente e Mediterrâneo foram fatores de proteção para obesidade geral e central em idosos.

            Dietary patterns and their associations with obesity in the Brazilian city of Rio de Janeiro.

            To evaluate the dietary patterns of adults living in the city of Rio de Janeiro, Brazil and their associations with body mass index (BMI). A survey was conducted in 1996 in a probabilistic sample of 2040 households. Weight and height were measured and food intake was based on an 80-item semi-quantitative food frequency questionnaire. Dietary patterns were identified through factor analysis. More than one-third of the adult population (20 to 60 years old) was overweight (BMI = 25 to 29.9 kg/m(2)), and 12% were obese (BMI >or= 30 kg/m(2)). Three major dietary patterns were identified: mixed pattern when all food groups and items had about the same factor loading, except for rice and beans; one pattern that relies mainly on rice and beans, which was called a traditional diet; and a third pattern, termed a Western diet, where fat (butter and margarine) and added sugar (sodas) showed the highest positive loading and rice and beans were strong negative components. Among men, the Western diet also included deep-fried snacks and milk products with high positive values. The traditional diet was associated with lower risk of overweight/obesity in logistic models adjusted for dieting, age, leisure physical activity, and occupation (13% reduction in men and 14% reduction in women comparing the traditional and Western diets). Factors contributing to the effects of the Brazilian traditional diet may include low-energy density, high-dietary fiber content, incorporation of low glycemic index foods such as beans, or a relatively low food variety.
