BackgroundPositive associations between dog ownership and adult health outcomes have been observed, but research involving youth is lacking.PurposeThe purpose of this study was to assess the relationship of family dog ownership to adolescent physical activity.MethodsData were collected on dog ownership in 618 adolescent/parent pairs between 9/2006 and 6/2008 and analyzed in 2010. Adolescent physical activity was assessed by ActiGraph accelerometers.ResultsAdolescents' mean age was 14.6±1.8 years and 49% were male. White and higher-SES adolescents were more likely to own a dog. In models adjusted for age, puberty, gender, race, total household members, and SES, adolescent physical activity (mean counts·min(-1)day(-1)) remained significantly associated with dog ownership (β=24.3, SE=12.4, p=0.05), whereas the association with minutes of moderate to vigorous physical activity per day became nonsignificant (β=2.2, SE=1.2, p=0.07). No significant results were observed for other adolescent characteristics.ConclusionsDog ownership was associated with more physical activity among adolescents. Further research using longitudinal data will help clarify the role that dog ownership may have on adolescent physical activity.Copyright © 2011 American Journal of Preventive Medicine.
