Abstract:

Objective: evaluate the effects of an interdisciplinary intervention program of nutritional education and physical exercise on body composition, lipid profile and nutritional knowledge of schoolchildren. Materials and methods: randomized clinical trial including 33 overweight students (60.6% female; 8.6 ± 1.0 years; 39.3 ± 7.0 kg; 133.3 ± 7.4 cm; 22, 0 ± 2.8 kg / m2). Participants were divided into two groups, intervention (n=14) and control (n = 19). The intervention program consisted of ten nutritional education sessions and 30 physical exercise sessions, carried out with the children and their parents for ten weeks. Anthropometric measurements, lipid levels, food consumption and the score of points in the digital game were assessed before and after the intervention. Results: The energy consumption in the intervention group showed a significant decrease (Δ = -503.40), compared to the control (Δ=-123.92) after the intervention. At the end of the program, a significant increase was observed for all variables of the lipid profile of children in the control group (TC: Δ = 24.58; HDL-c: Δ = 4.7; LDL-c: Δ = 15.48; and TG: Δ=38.26). However, for students in the intervention group, there was only a significant increase in HDL-c (Δ = 14.7). It was also found that the children in the intervention group increased the level of knowledge about healthy eating after intervention, which did not happen in the control group. Conclusion: The intervention was positive to increase HDL-c, decrease energy consumption, improve the percentage of fat and the knowledge about healthy eating of overweight children.
