Abstract

Background: This study examines the relations between a regular weekday bedtime with weight status, diet quality, physical activity, wellbeing, and parental rules among children 2 to 12 years of age from low-income populations. Methods: The study used baseline data collected in 2012, as part of a larger quasiexperimental study design. A convenience sample of parents of children in preschools, second, or fifth grade attending Head Start centers or elementary schools located in low-income catchment areas, in Houston and Austin, TX, were recruited to participate in the study (n = 32 elementary schools; n = 12 Head Start centers). Regular weekday bedtime was measured with the question "Does your child have a regular weekday bedtime?"Results: The sample of 1467 child-parent dyads were split approximately evenly by sex, and consisted of 44.4% Pre-K, 30.4% second grade, and 25.2% fifth grade students. Six hundred twenty-two (43.6%) children were overweight or obese. Children who had a regular bedtime had 15% lower odds of being overweight or obese (adjusted odds ratio [aOR]: 0.85, 95% confidence interval [CI]: 0.74-0.97, p-value: 0.017). Also, children who had a regular bedtime had 45% higher odds of eating the recommended number of fruits and vegetables (aOR: 1.45, 95% CI: 1.02-2.07, p-value: 0.039) and had physical activity more days of the week (β: 0.42, 95% CI: 0.26-0.57, p-value: <0.001). Conclusions: Having a regular weekday bedtime is associated with better weight status and several obesity-related health behaviors in children. Parental report of regular bedtimes for their children may be an indication of parenting skills related to other health-related behaviors for prevention of childhood obesity.
