Family embeddedness and older adult mortality in the United States.

Do different operationalizations of family structure offer different understandings of the links between family structure and older adult mortality? Using the American Health and Retirement Study (N = 29,665), we examine mortality risks by three measures of family structure: whether respondents have different family statuses (e.g. married vs. unmarried), volume of family members available (e.g. having one vs. two living immediate family members), and family embeddedness (e.g. having neither spouse nor child vs. having spouse but no child). We focus on three kin types: partner/spouse, children, and siblings. We find that differences in empirical estimates across measures of family structure are not dramatic, but that family embeddedness can show some additional heterogeneity in mortality patterns over family status variables or the volume of ties. This paper tests different ways of operationalizing family structure to study mortality outcomes and advances our understanding of how family functions as a key social determinant of health.
