Childhood obesity is a global public health problem with significant implications
for the health and wellbeing of children. The prevalence of childhood obesity is increasing
every decade, making it a recognized public health concern. This systematic review
aims to explore and evaluate the impact of school-based interventions on reducing
pediatric obesity among school-aged children. A systematic review of literature according
to the recommendations of the Preferred Reporting Items for Systematic Reviews and
MetaAnalyses (PRISMA) 2020 was conducted. Google Scholar, PubMed, and Cochrane were
the databases used. After screening for bias, inclusion and exclusion criteria, and
quality, 27 studies were included in the systematic review, and data were synthesized.
The results show that physical activity reduces obesity and improves cardiovascular
health. The nutritional change reduces the risk of obesity more than physical and
behavioral change could help maintain the improvements. Schools should adopt a blend
of physical activity and nutritional change to reduce prevent, reduce, and manage
obesity.
