Social inequality and health: the role of social capital.

The aim of the article is to examine whether and to what degree the unequal distribution of social capital in the population explains the relationship between socioeconomic position and health in Norway. Theoretical insight and empirical evidence seem to suggest that social capital mediates the effect of socioeconomic position on health outcomes. However, only a few studies have addressed this question and those that have done so have used few and simple indicators of social capital. This study is based on a nationwide cross-sectional survey (N = 3190) commissioned by Statistics Norway. The survey was designed to cover a comprehensive set of variables measuring different aspects of the theoretical construct of social capital. Two health outcomes, self-perceived health and longstanding illness, were analysed. The results showed that the mediating role of social capital between socioeconomic position and health was negligible for both health outcomes. After controlling for socio-demographic variables and socioeconomic position, only neighbourhood satisfaction and generalised trust showed a significant association with self-perceived health, whereas none of the social capital variables had any significant association with longstanding illness. Some theoretical and methodological implications of the results are discussed.
