Pediatric obesity is closely associated with obstructive sleep apnea (OSA) and short sleep duration. While multidisciplinary weight loss interventions are recommended for pediatric obesity management, the evidence for their effects on OSA severity and overall sleep in youth have not been systematically examined.
To conduct a systematic review and meta-analysis investigating the effects of multidisciplinary weight loss interventions on OSA severity and prevalence, and on overall sleep health in youth with obesity.
A systematic search of interventional studies (participants age range: 10–19 yrs) was performed using PubMed, CENTRAL and Embase, from inception to May 2019. The quality of the evidence was assessed using the Cochrane risk of bias tool.
Ten studies were included by the end of the screening process. Ninety percent of the included studies reported a decrease in OSA prevalence post-intervention, and OSA was normalized for 46.2–79.7% of the youth. The meta-analysis comprising seven longitudinal studies revealed significant reductions in apnea–hypopnea index (effect size: −0.51, 95%CI −0.94 to −0.08, p = 0.019), and oxygen desaturation index (effect size: −0.28, 95%CI = −0.50 to −0.05, p = 0.016). Seventy-five percent of the studies reported improved sleep duration in youth with OSA.
Evidence suggests that multidisciplinary weight loss interventions result in improvements in OSA severity and sleep duration in youth with obesity. Future randomized controlled trials are warranted to better assess and understand the independent implications of weight loss, fat mass decrease and chronic exercise on OSA and sleep health in this population.
