Comportamento alimentar e fatores de risco cardiovascular em crianças e adolescentes: JFcorações

Abstract

Introduction: Cardiovascular diseases are the leading cause of morbidity and mortality worldwide and its development is associated with eating habits. Objectives: Investigate the relationship between the frequency of meals and breakfast consumption habit (CM) with risk factors for cardiovascular disease (CRF) in children and adolescents. Methods: A crosssectional study with a sample of 708 schoolchildren (7-14 years) living in the city of Juiz de Fora, MG. A semi-structured questionnaire was used to collect sociodemographic, behavioral and relating to eating habits variables. To obtain the daily energy intake were used food 24hour recalls and food records three days. Weight, height, body fat, waist circumference and blood pressure were also performed. Finally, they collected blood samples for analysis of total cholesterol (TC), low lipoprotein (LDL) and high density (HDL) cholesterol, triglycerides and glucose levels. Data normality was verified by the Kolmogorov-Smirnov test and the MannWhitney test was used to identify significant differences in the values of central tendency. Moreover, Poisson regression models were constructed to evaluate how dietary habits were associated with the CRF. Results: Perform ≥ 4 meals was more prevalent among children than among adolescents (80.1% vs. 68.8%, p = 0.003) and more prevalent among males compared to females (77.9% vs. 66.6%, p = 0.001). Meal frequency < 4 were associated in children, family income < 3 minimum wages (p = 0.021) and in adolescents, the number of children in the family > 2 (p = 0.010). Even in the age group 10-14 years < 4 meals was related to associated with increased prevalence of overweight (p = 0.032) and LDL (p = 0.030) higher, after adjustments. Omit the CM was more common among adolescents compared to children (30.0% vs. 22.0%; p = 0.035) and among girls compared to boys (33.1% vs. 22.1%; p = 0.001). After adjustments, the omission of breakfast was associated in children, increased levels of diastolic blood pressure (DBP) (p = 0.003), CT (p = 0.001) and LDL (p <0.001) and in adolescents, associations were not found. Conclusion: Dietary habits as higher frequency of daily meals and CM consumption are related to the CRF, in children and adolescents and should be considered in discussions and health promotion actions.
