RESUMO

The prevalence of obesity in children and adolescents has increased in several countries including Brazil. This fact is strongly related to changes in lifestyle and eating habits. The nutrition transition is a phenomenon characterized by increased calorie intake and food consumption has been linked to obesity not only in the amount of food intake as well as the composition and diet quality. The Healthy Eating Index ¿ HEI ¿ is a measure of adherence to U.S. dietary recommendations. HEI is composed of a score of 100 points, in which 10 food components are evaluated and are designed to assess the quality of food, in order to monitor changes in dietary intake over time and as a basic instrument for development activities nutrition education and promotion of health in the population. Many studies have assessed the quality of food through this index, some showed a positive association between the HEI and the intake of essential nutrients. However few studies HEI correlated with markers of lipid profile. This research is concerned with the emergence of some cardiovascular risk factors in childhood and one of the causes related to this problem would be the type of food that children consume. In order to assess the quality of diet and lipid profile markers a crosssectional study was conducted to investigate the association between the HEI and markers of lipid profile and body mass index in schoolchildren of seven and eight years old, low socioeconomic status. The sample consisted of 305 school children, 173 boys and 132 girls, the overall mean age was 7.7 ± 0.4 years, overweight was diagnosed in 27.2% of children, and 11.5 % were classified as obese. The general average HEI score was 58.8 ± 7.7. This study found a high proportion of children with food consumption that needs to be improved and no child with good quality diet. In addition, we could not show an association between the HEI and serum lipid levels in children. The results of this research combined with intervention studies ever made highlight the need to develop and implement policies and nutrition programs in schools that target children and their families in order to increase the intake of vegetables, fruits and reduce the intake of processed products, sodium and fats.
