ABSTRACT It has been suggested that sleeping problems are causally associated with obesity in early life, but most studies examining this association have been cross-sectional. The authors used a population-based birth cohort of 2,494 children who were born between 1981 and 1983 in Brisbane, Australia, to examine the prospective association between early-life sleeping problems (at ages 6 months and 2-4 years) and obesity at age 21 years. The authors compared mean body mass indices (BMIs; weight (kg)/height (m)2) and persons in the categories of overweight (BMI 25.0-29.9) and obesity (BMI > or =30) among offspring at age 21 years according to maternally reported childhood sleeping problems. They found that young adult BMI and the prevalence of obesity were greater in offspring who had had sleeping problems at ages 2-4 years than in with those who had not had sleeping problems. These associations were robust to adjustment for a variety of potential confounders, including offspring sex, maternal mental health, and BMI, and several mediators, including adolescent dietary patterns and television-watching. These findings provide some evidence for a long-term impact of childhood sleeping problems on the later development of obesity.

    • "Furthermore, increasing epidemiological evidence indicates that sleep curtailment appears to be a potentially important risk factor for the development of obesity in children and adolescents (Al-Hazzaa et al., 2012; Chen et al., 2008; Gupta et al., 2002; Hitze et al., 2009; Marshall et al., 2008; Sekine et al., 2002; Yu et al., 2007). In addition, evidence also points to the long-term impact of childhood sleeping problems on later development of obesity (Al Mamun et al., 2007). "

    ABSTRACT: Abstract Background: Numerous studies have shown significant associations between short sleep duration and overall or abdominal obesity. However, no study has reported on the joint association of body mass index (BMI) and waist-to-height ratio (WHtR) with sleep duration in adolescents. Aim: To examine the joint associations of BMI and WHtR with sleep duration among Saudi adolescents. Subjects and methods: A school-based cross-sectional study was conducted involving 2852 secondary-school students (51.7% females) aged 15-19 years, randomly selected using a multistage stratified cluster sampling. Self-reported sleep duration was assessed and BMI was classified into high and low categories according to the IOTF classification, whereas WHtR categories were based on above and below 0.5. Results: The low BMI-low WHtR category had the longest mean sleep duration (7.27 hours/day), whereas the high BMI-high WHtR group had the shortest sleep duration (7.02 hours/day; p = 0.003) (aOR = 0.832, 95% CI = 0.698-0.992, p = 0.040). In addition, high BMI-low WHtR or low BMI-high WHtR groups didn't significantly associate with reduced sleep duration among adolescents. Conclusion: The joint association of high BMI-high WHtR increases adolescent's risk of having reduced sleep duration. Future research should seek to confirm such findings and provide an explanation for this association.

    • "Changes in health habits, with respect to diet and physical activity, are thought to be the major cause of overweight and obesity (Barlow & the Expert Committee, 2007; Finnish Medical Society Duodecim & Academy of Finland, 2005). Also, short sleep duration is possibly associated with increased childhood obesity (Al Mamun et al., 2007). Habits related to diet and physical activity are adopted early in childhood (Ritchie, Welk, Styne, Gerstein, & Crawford, 2005), and are very challenging to modify later in life. "

    • "Jordan and Robinson (2008) reviewed evidence of four causal mechanisms behind this relationship—lower resting energy expenditure, displacement of physical activity, food advertising leading to greater caloric intake, and eating while viewing leading to greater caloric intake—and concluded that the factor with the greatest research support is food advertising, which leads to encouragement of greater caloric intake and appetitive priming (Institute of Medicine , 2006). Media use is also implicated in poor quality and duration of sleep, a factor that itself is linked with obesity in research showing that inadequate sleep in toddlerhood predicts obesity in the school years (Taheri, 2006) and even at age 21 (Al Mamun et al., 2007). Obesity in return lowers the quality of sleep in childhood by contributing to obstructive sleep apnea (Ievers-Landis & Redline, 2007); thus, the relationship between poor sleep and obesity is cyclical.

    ABSTRACT: Abstract— Overweight in childhood sets the stage for a lifelong struggle with weight and eating and raises the risk of health problems, such as obesity, diabetes mellitus, hypertension, sleep apnea, and heart disease. Research from multiple disciplinary fields has identified scores of contributing factors. Efforts to integrate these factors into a single “big picture” have been hampered by the challenges of constructing theoretical models that are both comprehensive and developmentally adaptable. This article reviews select genetic and environmental factors influencing childhood overweight and obesity, then explicates an ecological model mapping these and other factors. The Six-Cs model extends previous theoretical work on childhood weight imbalance by acknowledging dimensions of factors specific to heredity as well as the environment, to activity as well as nutrition, to resources and opportunities as well as practices, and to development from birth through adolescence. This article concludes by discussing the model’s policy relevance and identifying important next steps for transdisciplinary research concerning child overweight and obesity.
