Abstract

Research on companion animals often portrays pet presence as health-protective, emphasizing its integrative function. This literature typically treats pet presence as an individual attribute and privileges average effects, overlooking how nonhuman ties are embedded within marital and gendered relational structures. Drawing on social integration, social cost, and gender-as-relational perspectives, we reconceptualize pet presence as a socially embedded tie whose health effects are context-dependent. Rather than uniformly beneficial, pet presence may activate integration or cost processes that amplify, attenuate, or reverse marital and gendered health gradients.

Using nationally representative data from the 2012 Health and Retirement Study (HRS), we estimate interactions among pet presence, marital status, and sex across cognitive performance and depressive symptomatology, including positive affect, negative affect, and functional impairment. We find no significant main effect of pet presence, offering no evidence for unconditional integration or cost processes. Marital gradients are evident, with patterns varying across outcomes, providing partial support for both social integration and social cost theories.

Interaction models reveal that pet presence reshapes marital differences in domain-specific ways. In binary comparisons, pet presence attenuates the marital advantage in cognitive performance but amplifies the marital advantage in affective well-being. In four-category models, pet presence attenuates—and in some cases reverses—the mental health advantages of never-married respondents, aligning more closely with cost activation than compensatory integration.

Three-way models further reveal gendered contingencies. Among men, pet presence functions as compensatory integration in the absence of marriage but is associated with worse affective and functional outcomes within marriage. Among women, associations are weaker and more mixed, with no consistent compensatory pattern. In the domain of functional impairment, pet presence is associated with greater impairment, particularly among men.

Overall, these findings extend social integration, social cost, and gender-as-relational theories beyond human-to-human ties, demonstrating that nonhuman relationships reorganize marital and gendered health gradients in structurally contingent ways.
