Abstract
The objective of this study was to assess the impact of television viewing during childhood and adolescence on body mass index (BMI) in children up to the age of 15 years. The study was based on an unselected birth cohort, assessed at birth and every 2 years from age 3 to 15 years. BMI and prevalence of overweight at all ages were significantly associated with mean hours of television viewing reported in the assessments up to that age. These associations were stronger in girls than boys. The associations remained significant after adjusting for parental body mass indices and socio-economic status. The authors conclude that time spent watching television is a significant predictor of BMI and overweight in childhood. Although the effect size appears small, it is larger than the effect sizes commonly reported for nutritional intake and physical activity. The authors go on to say that television viewing should be regarded as an important contributing factor to childhood obesity.
