When Does Social Capital Matter for Health? The Moderating Roles of Ethnicity, Income and Gender.

Abstract

Many empirical studies have suggested that social capital is positively related to health. However, little research has been conducted into how social capital is distributed and whether social capital matters for health uniformly or differentially across socio-economic statuses or racial/ethnic groups in the United States. This research seeks to address the gaps by examining the distribution of social capital across racial/ethnic, income, education and gender groups in the general population as well as among three Asian American subpopulations. It investigates whether social capital is associated with Asian Americans’ health, and, if so, whether such associations are moderated by ethnicity, income or gender.

The research draws data from two nationally representative surveys: the National Comorbidity Survey Replication (NCS-R), and the National Latino and Asian American Study (NLAAS). Exploratory factor analysis is used to generate social capital indicators from respondents’ social networks and their subjective evaluations of family and neighborhood life. Dependent variables include both physical and mental health outcomes as well as health behavior.

Findings reveal that Whites, females and individuals with higher incomes and more education have higher levels of social capital. Logistic regression analysis shows that while social capital, in particular structural social capital, is generally associated with better health outcomes, some dimensions of social capital are associated with an increased risk of smoking. More importantly, the study finds that social capital and health associations are moderated by ethnicity, income and gender, with Vietnamese and low-income individuals receiving higher returns from social capital. Additionally, the negative effect of social capital on smoking is much stronger for women than for men.

The findings of this study provide empirical evidence for a new line of reasoning which views the value of social capital for health as contingent on social context. Future research should take social context into account when examining the health effects of social capital. Additionally, social work practitioners should consider tailored interventions for targeted populations in order to maximize the benefits of social capital while minimizing its negative effects. As empirical investigations in this field are relatively new, additional research is needed to advance theory, research and practice.
