Consumo de macronutrientes e alterações na proteína c-reativa ultrassensível em adolescentes escolares de 10 a 14 anos de idade na cidade de João Pessoa, Brasil

Abstract

OBJECTIVE: To evaluate the association of total carbohydrate intake, total fat and saturated fats with hsCRP levels in adolescents aged 10 to 14 enrolled in public schools in Joao Pessoa, Brazil. METHODOLOGICAL CONSIDERATIONS: This is an epidemiological cross-sectional, school-based study, carried out based on data collected from a subsample of adolescents of both sexes, aged from 10 to 14 years, enrolled in the 6th grade – middle school in 2014, of the Longitudinal Study on Sedentary Behavior, Physical Activity, Eating Habits and Adolescent Health - Study LONCAAFS, held in João Pessoa, Brazil. The final sample consisted of 779 students. Socioeconomic data were collected (age, sex, economic class and skin color), nutritional status (BMI), food consumption data (total carbohydrates, total fats and saturated fats) and hsCRP. RESULTS: 54.56% female, 70.34% were between 11 and 12 years of age, 60.12% were of economic class C and 71.43% of the students were brown. 70% (539) of the students with altered levels of hsCRP. Of the students evaluated, 54.36% (293) are female. The prevalence of inadequate consumption was 29.25% in carbohydrates, 35.70% of total fats and 75.22% of saturated fats exceeding. 2.70% of the sample was classified as being underweight and 34.01% was the sum of those who were overweight or obese together. No significant independent associations were found between hsCRP and total carbohydrates, or total fats, or saturated fats, as well as skin color in the statistical models created. Significant associations of hsCRP with BMI, economic class and age were found. CONCLUSION: It is not possible to affirm the existence of an association between the inadequate consumption of macronutrients and the increase of serum levels of hsCRP in a sample of adolescents from public schools in Joao Pessoa, Brazil. The results also show a strong association between altered levels of hsCRP with nutritional status, age, and economic class.
