Evaluating Interventions Aimed at Reducing Obesity Prevalence among Adolescent Populations Globally

Abstract

Obesity among adolescents has become a serious worldwide community health issue, and its prevalence is on the increase in both high-income and low- and middle-income nations. In this research, the authors assess the efficacy of the interventions that are designed to decrease obesity in adolescents aged 10-19 years and rely on the evidence of various geographical and socio-economic settings. Recent peer-reviewed literature and reports by organizations like the World Health Organization were used to compare peer-reviewed school-based, community-based, family-centered, policy-driven, and digital interventions. The evidence has shown that multi-component interventions and those that include behavioral education, environmental changes, and policy support have been found to have the most reliable changes in body mass index (BMI) and the subsequent health behavior changes. School programs have a high scalability and policy interventions, like taxing sugar sweetened drinks, have broader population effects. Nevertheless, there is a wide range of variation in terms of the intervention outcomes based on cultural relevance, socioeconomic status and implementation fidelity. Digital health interventions have potential engagement but have difficulties in adhering to them over time. The same barriers such as inequity in resource allocation, lack of evaluation over the long term, and industry influence on food environments persist. The paper highlights the importance of context-dependent, multi-sectoral responses and long-term policy engagement to adequately prevent adolescent obesity on a global level.
