Classroom-Based Physical Activity and Sedentary Behavior Interventions in
Adolescents: A Systematic Review and Meta-Analysis.
J Phys Act Health. 2018 05 01;15(5):383-393
Authors: McMichan L, Gibson AM, Rowe DA
Abstract
BACKGROUND: It is reported that 81% of adolescents are insufficiently
active. Schools play a pivotal role in promoting physical activity (PA) and
reducing sedentary behavior (SB). The aim of this systematic review and
meta-analysis was to evaluate classroom-based PA and SB interventions in
adolescents.
METHODS: A search strategy was developed using the Population Intervention
Comparison Outcome Study (PICOS) design framework. Articles were screened
using strict inclusion criteria. Study quality was assessed using the
Effective Public Health Practice Project quality assessment tool (
http://www.ephpp.ca/tools.html ;). Outcome data for preintervention and
postintervention were extracted, and effect sizes were calculated using
Cohen's d.
RESULTS: The strategy yielded 7574 potentially relevant articles. Nine
studies were included for review. Study quality was rated as strong for 1
study, moderate for 5 studies, and weak for 3 studies. Five studies were
included for meta-analyses, which suggested that the classroom-based
interventions had a nonsignificant effect on PA (P = .55, d = 0.05) and a
small, nonsignificant effect on SB (P = .16, d = -0.11).
CONCLUSION: Only 9 relevant studies were found, and the effectiveness of
the classroom-based PA and SB interventions varied. Based on limited
empirical studies, there is not enough evidence to determine the most
effective classroom-based methodology to increase PA and SB.
