To investigate the associations between social capital (trust) and leisure-time physical activity. The 2004 Public Health Survey in Skåne is a cross-sectional study. In total, 27,757 individuals aged 18-80 years answered a postal questionnaire (59% participation). Logistic regression models were used to investigate the associations between trust, desire to increase physical activity and leisure-time physical activity. The prevalence of low leisure-time physical activity was 15.3% among men and 13.2% among women. Middle-aged men and older women, respondents born abroad, those with medium/low education, those with the desire to increase physical activity but needing support, and those reporting low trust had significantly higher odds ratios of low leisure-time physical activity than their respective reference groups. The associations between low trust and desire to increase physical activity and between low trust and low leisure-time physical activity remained in the multiple models. The positive association between low trust and low leisure-time physical activity remained after multiple adjustments. There is a concentration of men and women with low leisure-time physical activity who report the desire to increase their physical activity but think that they need support to do so. This group also has a significantly higher prevalence of low trust. Copyright © 2011 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.
