     In humans and other primates, strong social relationships have been linked to increased longevity, suggesting a key role for social connectedness in healthy aging across species. In humans, complex socioeconomic and behavioral factors hamper efforts to understand pathways that may underlie this phenomenon. Nonhuman primate societies can offer simplified models of links between social integration, health, and aging, but the data are challenging to acquire. Using long-term, longitudinal data from a natural population of savannah baboons (Papio cynocephalus) in Amboseli, Kenya, we examined links between social connectedness and biomarkers of health that show signatures of aging. Health measures included body condition, whipworm infection, glucocorticoids, and rates of injuries and illnesses. We used LMMs/GLMMs to model each health measure as a function of social connectedness, age, rank, reproductive status, and environmental covariates (alpha=0.05 for all statistical tests). In adult females, greater social connectedness to males predicted better body condition, and greater social connectedness to adult females predicted lower rates of whipworm infection. In adult males, greater social connectedness to adult females predicted better body condition and reduced rates of age-related hypercortisolism and whipworm infection. Social connectedness also imparted important costs: in both sexes, greater connectedness with the opposite sex predicted higher rates of injuries. Our findings demonstrate that social connectedness in baboons has divergent consequences for different measures of health during aging. Supported by NIH P01-AG031719.
