Objective:

To identify the effectiveness of educational interventions to prevent or treat obesity in adolescents.

Method:

It was an integrative review of the literature, based on the guiding question: "What is the effectiveness of obesity prevention / treatment interventions in adolescents?" The search was carried out in six electronic databases in Portuguese, English and Spanish in July 2020, which allowed the identification of 5,401 articles.

Results:

31 articles were identified that cover educational interventions based on nutritional and psychological support, physical activity and a healthy lifestyle. Physical activity, interdisciplinary behavioral, nutritional and lifestyle interventions predominated. The actions had a beneficial effect on the participants' quality of life, body mass index, daily exercise habits, and positive eating behavior among adolescents. The interventions for the control and prevention of obesity analyzed in this review had positive effects on reducing body weight.

Conclusion:

The findings pointed to the need for more studies to have greater control over the benefits and adherence to interventions aimed at preventing and treating obesity.
