Sleep duration and body-weight development during puberty in a Dutch children cohort

Abstract

Background: Short sleep duration is associated with obesity during childhood and adulthood. Objective: The objective of our study was to investigate the relationship between sleep duration and body mass index (BMI) from Tanner stages 1 to 5 in a Dutch children cohort. Design: In 98 children, anthropometric measurements and leptin concentrations were measured from age 7 to 16 years; body composition, physical activity (Baecke questionnaire), hours television viewing and self-reported sleep duration were measured yearly from age 12 to 16 years. Moreover, the polymorphisms of the FTO gene (rs9939609) and parental BMI's were determined. Results: At Tanner stages 1-5 sex differences were observed in height, body weight, waist circumference, fat mass per squared meter height and leptin concentrations per kg fat mass. Inverse relationships were observed between the change in BMI (kg m -2 ) and the change in hours of sleep per night (h) from Tanner stages 1 to 4 (r ¼ À0.68, Po0.001), from Tanner stages 2 to 5 (r ¼ À0.35, Po0.05) and from Tanner stages 1 to 5 (r ¼ À0.33, Po0.05). Univariate analysis of variance showed that with progressive Tanner stages, BMI increases and sleep duration decreases in an interrelated way independent of possible confounders (R 2 ¼ 0.38, Po0.02). Conclusion: Changes in BMI during puberty were inversely related to changes in sleep duration, independent of possible confounders.

Longitudinal associations between sleep duration and subsequent weight gain: A systematic review

“…Four children studies controlled for television viewing and no other media (22, 39, 53, 55) and one study controlled for television and video games (57). Given the recent dramatic increase in use of entertainment media, the early evidence of associations between television with both sleep and obesity, and reports that television comprised only 58% of total media use for youth in the U.S. in 2009 (21), it would seem essential that a broader range of media be routinely included a list of potentially confounding variables.…”

“…We excluded two examined articles (37, 38) that used longitudinal analyses to investigate the relationship between sleep duration and weight gain because the measure of sleep duration came at the end of the longitudinal period rather than at the beginning. We excluded another study because it measured the effect of BMI during childhood on sleep duration change (39). …”

Shorter Sleep may be a Risk Factor for Impaired Bone Mass Accrual in Childhood

“…These items, adapted from the Night Eating Questionnaire, were used to compute average hours of night sleeping and napping, and constituted total sleep. Similar sleep questions have been used with this age group in various studies [3;5;11;12]. …”

Parenting Practices that can Prevent or Reduce Childhood Obesity

“…(Shi, et al, 2010) Longitudinal studies have resulted in similar findings to these cross-sectional studies. Toddlers and children who slept fewer hours were more likely to be overweight three to six years later (Bell & Zimmerman, 2010;Lumeng, et al, 2007;Marshall et al, 2008) and adolescents whose sleep duration decreased during puberty were more likely to experience an increase in BMI during that same period (Rutters, Gerver, Nieuwenhuizen, Verhoef, & Westerterp-Plantenga, 2010). Another notable study found that short sleep duration in childhood predicted obesity at age 32 (Landhuis, Poulton, Welch, & Hancox, 2008).…”
