Abstract

Study Objective:

To assess the prospective relationship between sleep and obesity in a paediatric population.

Methods:

We performed a systematic search using PubMed, Embase, Web of Science and Cochrane (up to 25th September 2017). Included studies were prospective, had follow-up >1 year, had duration of sleep at baseline, and measures of incidence of overweight or obesity and/or changes in body mass index (BMI) z-score and BMI during follow-up. We extracted relative risks or changes in BMI z-score or BMI and 95% confidence intervals (CI) and pooled them using a random effect model. Results: Forty-two studies were included but, as there was significant heterogeneity, results are presented by age strata. Short sleep was associated with a greater risk of developing overweight or obesity in infancy (7 Studies, 14 738 participants, RR: 1.40; 95% CI 1.19 to 1.65; p<0.001), early childhood (8 Studies, 31 104 participants, RR: 1.57; 1.40 to 1.76; p<0.001), middle childhood (3 studies, 3 005 participants, RR: 2.23; 2.18 to 2.27; p<0.001) and adolescence (3 studies, 26 652 participants, RR: 1.30; 1.11 to 1.53; p<0.002). Sleep duration was also associated with a significant change in BMI z-score (14 studies, 18 cohorts, 31 665 participants) (mean difference -0.03; -0.04 to -0.01 per h sleep; P=0.001) and in BMI (16 studies, 24 cohorts, 24 894 participants) (mean difference -0.03 kg/m2; -0.04 to -0.01 for every h of increase in sleep; P=0.001).

Conclusions:

Short sleep duration is a risk factor or marker of the development of obesity in infants, children and adolescents.
