Sources and types of social support in youth physical activity.

This study examines the influence of sources and types of social support on youth physical activity. The sample comprised 372 youth (mean age=12.05 years, SD=1.63). Youth were 76% White and 50.3% female. The annual household income for the sample was 20% under $30,000; 30% $30,000-$49,999; 25% $50,000-$69,999; 13% $70,000-$89,999; and 12% $90,000 and above. Results revealed that friends who support and watch youth engage in activities are significantly and positively related to youth physical activity. Significant correlations existed among the type factors. Future research should examine the sources and nature of support and the mechanisms through which social support influences youth physical activity.
