“…Third, the validity of the data may be increased by complementing self-reported food records or dietary recalls, which may be subject to measurement errors or underreporting by mothers, with measured intake data in the feeding laboratory. It furthermore may be of interest for future studies to examine physical activity behaviors among children, especially those who are at increased risk for obesity, 38 in relation to food selection and dietary ED. Lastly, the present design, unlike a classic twin design or other genetically sensitive design, could not formally test the respective influence of genetic and environmental influences on dietary ED.…”

Objective: This study compared 4-year changes in daily energy density (ED; kcal/g) in children born at different risk for obesity, characterized the stability of ED and examined associations between ED and child body composition. Design: Prospective cohort study to measure habitual dietary ED of children who are born at different risk for obesity. Subjects: Children who were born at high risk (n ¼ 22) or low risk (n ¼ 27) for obesity based on maternal pre-pregnancy weight. Measurements: Three-day food records were collected from children's mothers at child ages 3, 4, 5 and 6 years. Three categories of ED were computed (food only, food and milk, and food and all beverages) and body composition assessed at each year. Results: The mean (7s.e.m.) ED increased over time across all children (linear trend: Po0.003): 2.1870.07 to 2.3270.06 kcal/ g (food only); 1.6670.07 to 1.8270.06 kcal/g (food and milk); and 1.2470.04 to 1.3770.05 kcal/g (food and all beverages). Intraindividual coefficients of variation were smaller than those previously reported for adults. Weight indices were not correlated with dietary ED (P40.05). Conclusion: Dietary ED increased in young children, irrespective of their predisposition to obesity, between the ages of 3 and 6 years. The genes that promote childhood obesity may not exert their influence through dietary ED, which may be more strongly influenced by environmental factors.

Background: Understanding the relative importance of overconsumption and physical inactivity to excess weight gain among children and adolescents can contribute to the development and evaluation of interventions and policies to reduce childhood obesity. However, whether energy intake or expenditure is the dominant contributor to childhood obesity is a subject of debate. To date, no study has systematically reviewed the literature on this subject. Methods: We searched PubMed and Ovid Medline (January 1970 to January 2010) for potentially relevant English-language abstracts and obtained full-text articles for the abstracts, which passed the initial inclusion-exclusion criteria. Reference lists of full-length articles were hand searched to identify additional studies potentially relevant for inclusion. Relevant studies were characterized into one of the following three categories: cross-sectional studies with a nationally representative sample, crosssectional studies among population subgroups and longitudinal studies.Results: This review identified 26 studies examining factors related to energy intake, energy expenditure and obesity among children and adolescents. Cross-sectional and longitudinal studies suggest that the primary determinant of energy imbalance at both the population and the individual levels is not definitive. Our findings further suggest that there is wide variation in data quality between studies. Future research in this area should aim to improve the accuracy of measures of energy intake, expenditure and their net balance over time; capitalize on under-utilized, non-traditional data sources, which have not been widely used; use modeling techniques to synthesize studies of shorter follow-up period and different outcome measures; and examine the unique determinants of energy imbalance among demographic groups at higher risk for obesity. Conclusions: On the basis of the current evidence, there is no consensus on the main driver of secular trends on weight gain among US children and adolescents. More research and better methods are needed to identify the relative contribution of energy intake and energy expenditure to obesity in the pediatric population.

“…Maternal education was used as a marker of socioeconomic status. Physical activity has been associated with lower BMI in adolescents, 22 and it has been suggested that more physical activity is associated with more sleep. 23 For these reasons, self-reported time spent in moderate-to-vigorous physical activity (MVPA) was included as a covariate.…”

WHAT'S KNOWN ON THIS SUBJECT: Short sleep may be an adolescent obesity risk factor, but most evidence is from crosssectional studies. Three longitudinal studies have investigated the association between sleep duration and adolescent obesity, finding mixed results.WHAT THIS STUDY ADDS: Shorter sleep was associated with increases in BMI from age 14 to 18, especially at the upper tail of the BMI distribution. Increasing daily sleep to 10 hours per day could help to prevent adolescent obesity. abstract OBJECTIVES: Short sleep has been associated with adolescent obesity. Most studies used a cross-sectional design and modeled BMI categories. We sought to determine if sleep duration was associated with BMI distribution changes from age 14 to 18.METHODS: Adolescents were recruited from suburban high schools in Philadelphia when entering ninth grade (n = 1390) and were followedup every 6 months through 12th grade. Height and weight were selfreported, and BMIs were calculated (kg/m 2 ). Hours of sleep were self-reported. Quantile regression was used to model the 10th, 25th, 50th, 75th, and 90th BMI percentiles as dependent variables; study wave and sleep were the main predictors.RESULTS: BMI increased from age 14 to 18, with the largest increase observed at the 90th BMI percentile. Each additional hour of sleep was associated with decreases in BMI at the 10th (-0.04; 95% confidence interval [CI]: -0.11, 0.03), 25th , and 90th (-0.27; 95% CI: -0.45, -0.09) BMI percentiles. The strength of the association was stronger at the upper tail of the BMI distribution. Increasing sleep from 7.5 to 10.0 hours per day at age 18 predicted a reduction in the proportion of adolescents .25 kg/m 2 by 4%.
