Dog ownership and adolescent physical activity

Background: Positive associations between dog ownership and adult health outcomes have been observed, but research involving youth is lacking. Purpose: The purpose of this study was to assess the relationship of family dog ownership to adolescent physical activity. Methods: Data 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. Results: Adolescents' 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^-1day^-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. Conclusions: Dog 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.
