Abstract:
Many studies conducted in Western societies suggest that social capital
has a negative relationship with health. People with higher social capital are more
likely to be in good health than those with lower social capital. However, few
studies have explored the link between social capital and health in Asia. The
purpose of the present study is to explore the link between social capital and selfreported
cardiovascular disease (CVD) and related risk factors by using data from a
baseline census of 100 selected communities in Kanchanaburi province of
Thailand. The data used in this study were collected in 2000 and included a total of
27,842 individuals aged 15 years and above. A social capital index was constructed
based on 12 variables related to social support, media exposure, social networks
and family ties. Multiple logistic regression and generalized linear model (GLM)
statistical analysis were applied in this study. Bivariate results showed that social
capital is negatively related to self-reported heart disease. After controlling for
demographic factors, this negative relationship was not statistically significant. The
relationship between social capital and risk factors of CVD, such as hypertension,
smoking and alcohol consumption were also examined. There was a negative
bivariate relationship between social capital and self-reported hypertension. This
relationship became positive after controlling for other factors. Social capital is
negatively related to smoking and liquor consumption, even after controlling for
other factors. The results also showed that social capital was influenced by
socioeconomic status and demographic factors. The findings of the study indicate
that the effects of social capital on health are complex. This study provides clues
for exploring the causal relationship in future research, perhaps by using
longitudinal studies, expanding the information collected on social capital in order
to better measure the concept, and also obtaining measures on other intervening
variables. It is necessary to design family-based and community-based
interventions for providing remedial activities in health promotion, rather than
focusing on individual level interventions. This study also suggests that for social
science studies related to health, biological factors should be combined with the
social factors.
