Introduction: Physical activity (PA) is one of the treatments to promote weight loss in children with obesity. The WHO advices to perform moderate to vigorous (MV) PA during 60-min daily. It is necessary to measure the effect of increasing PA and the adherence to therapy.
Aims: To evaluate PA using accelerometry at the onset and after 8 weeks of treatment with nutritional intervention and increase in PA.
Patients, material and methods: one hundred and twenty-two children and adolescents (age 7–16 years) diagnosed with abdominal obesity (waist circumference <p90) were included in a randomized-controlled clinical trial (NCT 03147261). Anthropometrical data: weight, height, BMI, waist (W), hip (H) and fat mass percentage. Patients were randomized in 2 groups: control, treated with the conventional recommendations and intervention group, treated with moderate caloric restriction according to BMI. Both groups were instructed to increase their PA in 200 minutes per week. The PA was determined by 4-day accelerometry including the weekend (Actigraph GT3X accelerometer, Actlife software).
Results: Full accelerometer data were obtained from 106 patients (40 boys), mean age 11.31 (2.47SDS). PA was superior during the week than during the weekend (P<0.001) and the contrary was observed in sedentary time (P<0.001). At the beginning of the study 25% of children fulfilled the WHO recommendations (32% during the week and 16% during the weekend) and 28% after 8 weeks. In the control group sedentary time increased (P=0.007) and light PA (LPA) decreased (P=0.003). The intervention group increased the MVPA (P=0.024) and decrease the LPA (P=0.04). In both groups a decrease (P<0.005) in weight, BMI-SDS, W, W/H index and leptin and glucose serum levels, was observed. In the intervention group serum insulin levels and HOMA also decreased (P<0.05).
Conclusions: Objectively measurement of PA by accelerometry indicates that the intervention group improves the MVPA. The patients included in this study performed more PA during the week than during the weekend.
