Background:The long incubation periods of cardiovascular diseases offer opportunities for controlling risk factors. In addition, preventive interventions in childhood are more likely to succeed because lifestyle habits become ingrained as they are repeated.Objective: To investigate the effects of recreational physical activities, in combination or not with a qualitative nutritional counseling, in cardiometabolic risk factors of students with dyslipidemia and abdominal obesity.Methods: Students (8-14 years old) were randomly divided into three groups (n=23 each): i) Control; ii) PANC, students undergoing Physical Activity and Nutritional Counseling, and iii) PA, students submitted to Physical Activity, only. Blood samples (12-h fasting) were collected for biochemical analysis and anthropometric markers were also assessed. Two-Way RM-ANOVA and Holm-Sidak's test, and Friedman ANOVA on Ranks and Dunn's test were applied. P ≤ 0.05 was considered significant. Effect sizes were evaluated by Hedges' g and Cliff's δ for normal and non-Gaussian data, respectively.Results: Compared to the control group and to baseline values, both interventions caused significant average reductions in total cholesterol (11%; p <0.001), LDL-c (19%; p=0.002), and non-HDL-c (19%; p=0.003). Furthermore, students in the PANC group also experienced a significant decrease in body fat compared to baseline (p=0.005) and to control (5.2%; g=0.541). Conclusions:The proposed strategies were effective to reduce cardiometabolic risk factors in children and adolescents. The low cost of these interventions allows the implementation of health care programs in schools to improve the students' quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
