Background. The presence of a television in a child’s bedroom is associated with an increased risk of obesity in children. The presence of a television in a child’s bedroom may adversely affect children’s sleep duration by displacing the amount of time a child could spend sleeping. The purpose of this study was to examine the association of having a television in the bedroom with sleep duration and child body mass index (BMI). We hypothesized that the presence of a television in the bedroom would be positively associated with shortened sleep duration and BMI percentile in children. Methods. This was a cross-sectional analysis of baseline data obtained from a healthcare-based obesity prevention and control intervention involving 297 low-income, Latino parent-child dyads in San Diego, California, USA. Pediatric patients from a community health center who were identified as at-risk for overweight, overweight and obese were enrolled in this study. Parents were asked to report on the typical bedtime and wake times of their child to determine average nightly sleep duration, and whether there was a television in the child’s bedroom. Child BMI (kg/m2) and BMI percentile were calculated using measured height and weight. Linear regression analyses were used to determine the relationship between having a television in the bedroom and sleep duration on a child’s BMI, controlling for family income, parent educational level, as well as child sex and age. Results: All children in the study identified as Latino and had a mean age of 8.1 (SD=1.5). Over sixty-three percent of parents had a monthly household income of less than $2000 and 40.7% of the parents had less than a high school education. The average BMI percentile for children was 92.1 (SD=6.3); 38.5% were overweight and 44.6% were obese. Parents reported that 75.7% (n=224) of children had a television in their bedroom. The average amount of sleep each day was 9.9 hours (SD=0.8). Sleep duration and having a television in the bedroom were not related with child BMI percentiles. Conclusion. Given the ubiquitous nature of electronic and portable media, further research is needed to investigate the association between the presence of other media in the bedroom (e.g., tablets, smartphones) and child sleeping habits on child excessive weight.
