Couple Religiosity and Well-Being Among Older Adults in the United States.

Objectives: This article evaluates whether couples' religious similarity is consequential for the health of older married men and women. Alternatively, we examine whether women's religiosity alone is health-protective to their husbands. Methods: Using dyadic data from the US National Social Life, Health, and Aging Project, a representative sample of 913 individuals ages 62-91 plus their marital partners, we perform latent-class analysis to separate older couples into classes based on religious characteristics. Ordered logistic regression models are then used to assess whether different combinations of religious (dis)similarity are associated with married men and women's well-being. Results: We find that older women in highly religious, homogamous marriages report better mental and physical health relative to women in heterogamous and secular (non-religious) marriages. No significant associations were observed for men. Discussion: Our results emphasize that religiosity is not only an individual trait-dis/similarities within a couple have important implications for older women's well-being.
