Abstract: Background: Some studies in adults indicate a positive correlation between eating later in the day and overall energy intake as well as body weight status. Thus the time of food intake may be a risk actor in childhood obesity. This study was designed to describe the proportion of energy consumed in the time from 4 pm to midnight measured in two-hour increments and to determine a potential association between the time of proportion of energy consumed and body weight status. ethods: Dietary anthropometric and socio-demographic data of 2–18 year olds (N = 11 072) of the National Health and Nutrition Examination Survey (NHANES) 1999–2004 was examined to describe the proportion of total energy consumed within two-hour time periods between 4 pm and midnight. To examine the potential association between eating later in the day and body weight tatus generalized estimating equations (GEE) models were used to quantify the effect of time trends (proportion of total energy consumed in each 2-hour time period from 4 pm to 11.59 pm) on body weight status. Analysis was conducted in the total sample and in subgroups stratified by sex ethnic group (Non-Hispanic white Non-Hispanic black Mexican American Other Hispanic and Other Race including multi-racial) and age group (2–5 6–11 and 12–18 year olds). Complex ample survey analysis were used to assess differences at a significance level of p-value < 0.05. esults: Proportion of energy consumed varied by sex ethnic group and age groups between 4 pm and 11.59 pm. Compared to healthy weight children overweight school-age children consumed significantly higher while overweight adolescents consumed significantly lower proportions of total daily energy with each advancing two-hour time increment. onclusion: The association between the circadian rhythm of eating and body weight status needs to be investigated further to examine the effect of time of consumption on the risk of childhood obesity. Especially longitudinal studies in diverse child populations would help elucidate the importance of time of eating on obesity.
