Introduction: Obesity is the most common nutritional disorder in the paediatric age. Decreased physical activity and increased inactivity are important factors that are involved in this pandemic. The highest prevalence of obesity in Europe is in the South.

Objective: To study the relationship between the practice of a regulated sport and lipid profile in overweight children and adolescents.

Material and methods: 318 overweight children, age range 3–17 years (11.07±2.7), attending the Pediatric Nutrition consultation of a tertiary hospital. 42.5% are male. Anthropometry was performed and the sample was stratified according to the international standard of Cole. Physical activity is assessed using a validated questionnaire that collected belonging to a sports club and time spent at the same. Serum cholesterol (CT) and triglycerides (TG) are determined by ADVIA 2400 and HDL-C and LDL-C by cellulose acetate electrophoresis HELENA. Statistical Analysis SPSS19.

Results: 61.9% of children are obese. 36.8% of the sample belongs to a sports club. Children belonging to a sports club have a lower BMI (25.4 vs 27.1 k/m2, ns) and lower CT(162.7 vs 168.2 mg/dl, ns) and LDL-c (97 vs 101.7 mg/dl, ns) and HDL-c (48.3 vs 44 mg/dl, P=0.001) significantly higher. In the group of children belonging to a sports club and play sports more than 3hr a week showed no differences in BMI (25.2 vs 25.7 k/m2, ns). However, these children showed higher serum levels of HDL-c (49.7 vs 46.3 mg/dl, ns) and lower levels of LDL-c (101.3 vs 103.3 mg/dl, ns) and TG (66.7 vs 73.5 mg/dl, ns) than children playing less than 3 h a week.

Conclusion: Regulated sport improves lipid profile in overweight children, independently of BMI and specially by increasing HDL-c levels. The spent time in sport seem play an important role in the improving of lipid profile. Therefore the promotion of the regulated physical activity during a adequate time should form part of strategies for prevention of metabolic risk in paediatric obesity.
