Secondary school randomized controlled interventions with a minimum dual approach to health and the links to BMI in pupils: A systematic review and meta-analysis within the project From Science 2 School
Abstract
Introduction & Purpose
Health behavior offers a pivotal domain of health for managing current global crises, including physical inactivity and overweight/obesity (Schroeder, 2007). However, adults have limited capacity for adopting healthy behavior into their lifestyle (Prochaska & Velicer, 1997). Schools offer an ideal setting for implementing health interventions considering the breadth of children that can be reached and the amount of time children spend in school (Tanous et al., 2022). The present study hypothesized that appropriately planned physical activity (PA) intervention for pupils and during compulsory secondary school time results in healthier body weight management.
Methods
A systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, a published protocol (Tanous et al., 2022), and a trial registration was completed on the International Register of Systematic Reviews (PROSPEO: CRD4202347770). The databases searched (12/2021) included PubMed, Education Source, and EMBASE. Only school-based randomized controlled trial interventions on PA and/or diet published in English or German were included. The study population included pupils (10-19 years of age) enrolled in secondary schools and without major nutritional deficit or unstable health condition. The study sample was refined using exclusion criteria: (i) no outcome on body weight, body mass index (BMI), or self-reported,…
