Relação do perfil lipídico com os macronutrientes da dieta de adolescentes de escolas públicas do município de João Pessoa – PB.

Abstract

This study aimed to evaluate the relationship between lipid profile and dietary macronutrients of adolescents from public schools in. It is a cross-sectional study that evaluated 777 schoolchildren of both sexes, regularly enrolled in the 6th year of elementary school II of municipal and state schools, aged 10 to 14 years, participating in the Longitudinal Study on Sedentary Behavior, Physical Activity, Habits Food and Adolescent Health (LONCAAFS Study) in João Pessoa, PB. Data collection took place in 2014 and socio-demographic variables, food consumption and blood collection after 12 hours of fasting were collected. Lipid profile analysis. In order to identify the lipid profile, cut-off points were considered: total cholesterol (≥170mg / dL), LDL-C (≥130mg / dL), triglycerides (≥130mg / dL), HDL-c (<45mg/dL). For macronutrient consumption, the following recommendations were used: 45- 65% (carbohydrates), 25-35% (lipids) and 10-30% (proteins). 67% of the adolescents who participated in the study presented total cholesterol within the normality values and 58% of the adolescents had below-desirable HDL-c levels (≤45 mg / dl). Consumption of macronutrients was within the recommended range. Only lipid consumption associated with serum levels of HDL-c presented a statistically significant value, that is, p = 0.03. A high prevalence of altered total cholesterol was observed in the adolescent population, as well as low HDL-c. Studies that evaluate the relationship of foods and food groups to the lipid profile should be performed for better substantiation.
