Cross-sectional associations between sociocultural factors and objectively-measured physical activity in a sample of 397 children (aged 9) and 213 adolescents (aged 15) were investigated. Associations with children’s physical activity were found for mothers’ physical activity (β=80,p < .01), parental participation (β=67,p = .01), mother’s age (β=−8,p < .01) and, in girls, fathers’ physical activity (β=73, p = .045; R2 for final model: 10.6%). No sociocultural factors were significantly associated with adolescents’ physical activity. Parental factors might be important targets for interventions to increase children’s physical activity but other factors may have greater influence. For adolescents’ physical activity, factors from other domains may be more important to target.

We examine the relative importance of both objective and perceived environmental features for physical activity in older English adults. Self-reported physical activity levels of 8,281 older adults were used to compute volumes of outdoor recreational and commuting activity. Perceptions of neighborhood environment supportiveness were drawn from a questionnaire survey and a geographical information system was used to derive objective measures. Negative binominal regression models were fitted to examine associations. Perceptions of neighborhood environment were more associated with outdoor recreational activity (over 10% change per standard deviation) than objective measures (5–8% change). Commuting activity was associated with several objective measures (up to 16% change). We identified different environmental determinants of recreational and commuting activity in older adults. Perceptions of environmental supportiveness for recreational activity appear more important than actual neighborhood characteristics. Understanding how older people perceive neighborhoods might be key to encouraging outdoor recreational activity.
