This is a cross-sectional school-based study that evaluated the prevalence and associated factors of the daily intake of fruit and vegetables by adolescents at public schools in Caruaru, Pernambuco. Poisson regression with a hierarchical model, including sociodemographic variables in the first hierarchical level, behavioral variables in the second and diet-related variables in the third was used to assess the factors associated with fruit and vegetable intake. The results showed that of the 600 adolescents interviewed, 10% reported never eating fruit and 30.7% mentioned not eating vegetables. Prevalence of fruit intake was 32.9% and vegetables 29.0%. Only 6.5% reported eating both kinds of food daily. Merely the daily vegetable intake showed a significant difference according to sex (higher among girls). Daily fruit intake was 63% higher among adolescents living in urban areas. Not consuming alcohol was associated with higher fruit intake, though not to vegetable intake. Daily intake of fruits and vegetables was 2.4 times higher among adolescents who consumed rice and beans daily. Daily fruit and vegetable intake among adolescents in Caruaru is below the recommendations, and was associated with gender, residence area, consumption of alcoholic beverages and consumption of rice and beans.

The scope of this paper was to evaluate the quality of the diet of the elderly in the city of Avaré, São Paulo state, using the Healthy Eating Index (HEI). A cross-sectional population-based study was conducted by home interviews. The sample consisted of 73 individuals, randomly selected among elderly people from the public health system in the city. Food consumption was measured by 3 24-hour recalls. The HEI adapted to the Brazilian population was applied for evaluation purposes. It is believed that this study is the first in Brazil to apply the HEI using 3 surveys of the 24-hour recall type among the elderly population. This methodology was chosen because, as described in the literature, a single day does not accurately reflect the usual intake of an individual due to the high interpersonal variance in consumption. It was found that 32.9% of elderly people were on a poor quality diet, 60.3% needed adjustments and 6.8% had a good quality diet. The conclusion that can be drawn is that the elderly population studied need to improve their diet, which emphasizes the importance of policies geared to encouraging healthy eating in old age.

The scope of this study was to analyze the factors associated with the prevalence of being overweight and obesity in a population of low-income adult women living in a metropolitan region and its association with socioeconomic, demographic, reproductive and lifestyle variables, highlighting the importance of healthy eating. A population-based, cross-sectional study was conducted with a random sample of 758 women aged 20 or older living in Campos Elíseos – Duque de Caxias – State of Rio de Janeiro. Bivariate and multivariate hierarchical regression was used to identify factors associated with overweight and obesity. A prevalence of 23% of obesity was found, and a prevalence of 56% of being overweight and obesity combined. An inverse association was found between years of study, being overweight and obesity. Most of the women reported having a healthy diet (73.6%) that increased positively with income, education and age. Failure to consume vegetables weekly was associated with being overweight and not having a healthy diet was associated with obesity. The results of this study demonstrate that even in low-income populations, a higher level of education has an impact on prevention of this problem and in food choices.

The scope of this study was to evaluate the effectiveness of two methods of educational nutritional intervention together with women who practice regular physical activities by fostering the adoption of healthy eating habits. The study population consisted of 52 women aged between 19 and 59 who frequented the Academia da Cidade Program in Aracaju in the State of Sergipe. The study was a randomized comparison of two intervention groups and was of the pre-test/post-test variety. The educational activities were based on two protocols – one less intensive (P1 Group) and one more intensive (P2 Group) – over a period of two months. The variables analyzed were nutritional knowledge, anthropometric measurements and changes in eating habits. The changes identified were improvement in eating habits and reduction in weight and Body Mass Index for the P2 group. The modifications identified referred mainly to increased consumption of fruit and vegetables, reduction of fat in cooking, reduction in the volume of food eaten per meal and increased meal frequency. In relation to nutritional knowledge, only 2 of the 12 questions showed significant changes. The most intensive method proved effective in changing dietary habits leading to weight loss.
