The role of social support and integration for understanding socioeconomic disparities in self-rated health and hypertension

Abstract

This paper examines socioeconomic (socioeconomic status, SES) disparities in self-rated health and hypertension among 29,816 US adults aged 25 and older using data from the 2001 wave of the National Health Interview Survey. Our purpose is to examine how influential measures of social support and social integration are for each health outcome, and whether support and integration operate by mediating, or buffering, the effects of SES on health. Multivariate regression models show no significant influence of emotional support, but do indicate that many aspects of social integration are directly associated with self-rated health and hypertension, although these measures do not mediate the relationship between SES and health. However, interaction tests show substantial evidence that measures of social integration buffer some of the negative effects of low SES, particularly the negative influence of not working on self-rated health. In addition, findings indicate potential evidence of help-seeking behavior among adults who did not finish high school or who report financial barriers to medical care. Overall, our findings suggest that social programs designed to foster social integration (e.g., free or low-cost bus fare to promote visits with friends and family) may improve health among persons with low levels of education, who are not working, or who have problems accessing medical care because of financial problems.Health disparities Socioeconomic status Social support Social integration Self-rated health Hypertension USA
