Increased income strongly correlates with improved health and lower mortality risk. Yet in spite of having a lower mean and median income, both Hispanics and the foreign-born living within the U.S. have higher longevity compared with native-born, non-Hispanics. We explored the role of structural social capital in conferring protection against poor health outcomes among Hispanics and the foreign-born in the US. We used the National Health and Nutrition Examination Survey III 1988-1994 linked to prospective mortality follow up to examine the relationship between five measures of structural social capital and: (1) intermediate health outcomes (blood pressure, plasma fibrinogen, C-reactive protein, and total cholesterol) and (2) a distal outcome (all cause mortality). The foreign-born and Hispanics generally had lower measures of structural social capital relative to native-born non-Hispanics. Additionally, while structural social capital was protective against poor health or mortality among native-born persons, the association disappeared for Hispanics and the foreign-born.
