A number of studies in recent years have identified both self-report and objectively measured accessibility of recreational facilities as important predictors of physical activity in youth. Yet, few studies have: (1) examined the relationship between the number and proximity of objectively measured neighborhood physical activity facilities and respondents_ perceptions and (2) compared objective and self-report measures as predictors of physical activity. This study uses data on 1,367 6th-grade girls who participated in the Trial of Activity for Adolescent Girls (TAAG) to explore these issues. Girls reported whether nine different types of recreational facilities were easily accessible. These facilities included basketball courts, golf courses, martial arts studios, playing fields, tracks, skating rinks, swimming pools, tennis courts, and dance/ gymnastic clubs. Next, geographic information systems (GIS) were used to identify all the parks, schools, and commercial sites for physical activity located within a mile of each girl_s home. These sites were then visited to inventory the types of facilities available. Girls wore accelerometers to measure their weekly minutes of non-school metabolic equivalent weighted moderate-to-vigorous physical activity (MW-MVPA). The number of facilities within a half-mile of girls_ homes strongly predicted the perception of easy access to seven out of nine facility types. Both individual facility perceptions and the total number of facilities perceived were associated with increased physical activity. For each additional facility perceived, girls clocked 3% more metabolic equivalent weighted moderate-to-vigorous physical activity (pG0.001). Although girls tended to record 3% more of this kind of physical activity (pG0.05) per basketball court within a mile of their homes, objective facility measures were otherwise unrelated to physical activity. The results from this study suggest that raising the profile of existing facilities may help increase physical activity among adolescent girls.

Research suggests that fathers' involvement in their children's lives is associated with enhanced child functioning. The current study examined (a) whether presence of a father was associated with better child functioning, (b) whether children's perceptions of fathers' support was associated with better functioning, and (c) whether the above association was moderated by the father's relationship to the child, the child's race, and the child's gender. Participants included 855 six-year-old children and their caregivers. Father presence was associated with better cognitive development and greater perceived competence by the children. For children with a father figure, those who described greater father support had a stronger sense of social competence and fewer depressive symptoms. The associations did not differ by child's gender, race, or relationship to the father figure. These findings support the value of fathers' presence and support to their children's functioning. Priorities for future research include clarifying what motivates fathers to be positively involved in their children's lives and finding strategies to achieve this.
