“…Additionally, children with irregular sleep-wake times (greater than 45 minute delays in bedtimes on weekends) and long sleep durations had larger increases in BMI over time than children with regular sleep-wake times and long sleep durations (Miller et al, 2014). These findings suggest that regular sleep-wake patterns are important for maintaining a healthy BMI during growth and development.…”

The relationship between sleep duration and obesity in adolescents is inconclusive. This may stem from a more complex relationship between sleep and obesity than previously considered. Shifts towards evening preferences, later sleep-wake times, and irregular sleep-wake patterns are typical during adolescence but their relationship to body mass index has been relatively unexplored. This cross sectional study examined associations between sleep duration, midpoint of sleep, and social jetlag (estimated from seven days of continuous actigraphy monitoring) and morningness/eveningness with body mass indexes (BMI z scores) and waist to height ratios in 14 to 17 year old adolescents. Seventy participants were recruited from 9th and 10th grades at a public high school. Participant characteristics were as follows: 74% female, 75% post-pubertal, 36% Hispanic, 38% White, 22% Black, 4% Asian, and 64% free/reduced lunch participants with a mean age of 15.5 (SD, 0.7). Forty one percent of the participants were obese (BMI ≥ 95th percentile); 54% were abdominally obese (waist to height ratio ≥ 0.5). Multivariable general linear models were used to estimate the association between the independent variables (school night sleep duration, free night sleep duration, midpoint of sleep (corrected), social jetlag, and morningness/eveningness) and the dependent variables (BMI z scores and waist to height ratios). Social jetlag positively associated with BMI z scores (p < 0.01) and waist to height ratios (p = 0.01). Midpoint of sleep (corrected) positively associated with waist to height ratios (p = 0.01). After adjusting for social jetlag, school night sleep duration was not associated with waist to height ratios or BMI z scores. Morningness/eveningness did not moderate the association between sleep duration and BMI z scores. Findings from this study suggest that chronobiological approaches to preventing and treating obesity may be important for accelerating progress in reducing obesity rates in adolescents.

“…Similarly, failure to account for SDB may lead to confounding of the association between sleep duration and obesity. Although two recent studies report that sleep timing(35) and duration(35, 36) elevate obesity risk in children, independent of SDB, neither was longitudinal.…”

Objectives To examine independent associations between sleep-disordered breathing (SDB), sleep duration from birth through 6.75 years, and body mass index (BMI) through 15 years of age in a population-based cohort. Study design The Avon Longitudinal Study of Parents and Children (ALSPAC) collected parent questionnaire data on child sleep duration and sleep disordered breathing (SDB) symptoms from birth through 6.75 years and child BMI from ALSPAC research clinics (n=1,899). For SDB, logistic regression models-- minimal, confounder, and confounder + sleep duration adjusted-- examined associations with BMI at 7, 10, and 15 years. For short sleep duration (≤ 10th centile), comparable SDB-adjusted models examined associations with BMI at 15 years. Results Children with the worst SDB symptoms vs. asymptomatic children, had increased odds of overweight at 7 (OR=2.08, 95% CI= 1.04-4.17), 10 (OR= 1.79, 95% CI= 1.02-3.16), and 15 years (OR= 2.25, 95% CI= 1.27-3.97) in models adjusted for sleep duration. Similarly, short sleep duration at ≈5-6 years was associated with overweight at 15 years, independent of SDB. Children with short sleep duration at 4.75 years were more likely to be overweight at 15 years in minimally (OR= 2.21, 95% CI= 1.52-3.20), confounder (OR= 1.99, 95% CI= 1.34-2.96), and SDB-adjusted (OR= 2.04, 95% CI= 1.36=3.04) models. Conclusion Both SDB and short sleep duration significantly and independently increase children’s odds of becoming overweight. Findings underscore the potential importance of early identification and remediation of SDB, along with insufficient sleep, as strategies for reducing childhood obesity.

Nighttime Sleep Duration and Sleep Behaviors among Toddlers from Low-Income Families: Associations with Obesogenic Behaviors and Obesity and the Role of Parenting

Background: Shortened sleep duration is associated with poor health and obesity among young children. Little is known about relationships among nighttime sleep duration, sleep behaviors, and obesogenic behaviors/obesity among toddlers. This study characterizes sleep behaviors/duration and examines relationships with obesogenic behaviors/obesity among toddlers from low-income families.Methods: Mothers of toddlers (age 12-32 months) were recruited from urban/suburban sites serving low-income families. Mothers provided demographic information and completed the Brief Infant Sleep Questionnaire (BISQ); a 6-item Toddler Sleep Behavior Scale was derived (TSBS-BISQ, higher score reflects more recommended behaviors). Toddler weight/length were measured; obesity defined as ‡95th percentile weight-for-length. Results: Sample included 240 toddlers (mean age = 20.2 months), 55% male, 69% black, 59% urban. Toddlers spent 55.4 minutes/ day in MVPA, mean HEI-2005 score was 55.4, 13% were obese. Mean sleep duration was 9.1 hours, with 35% endorsing 5-6 recommended sleep behaviors (TSBS-BISQ). In multivariable models, MVPA was positively related to sleep duration; obese toddlers had a shorter nighttime sleep duration than healthy weight toddlers [odds ratio = 0.69, p = 0.014]. Nighttime sleep duration was associated with high TSBS-BISQ scores, F = 6.1, p = 0.003.Conclusions: Toddlers with a shorter nighttime sleep duration are at higher risk for obesity and inactivity. Interventions to promote healthy sleep behaviors among toddlers from low-income families may improve nighttime sleep duration and reduce obesogenic behaviors/obesity.
