To determine the extent to which social relationships influence mortality risk, identify the most predictive relationship dimensions, and evaluate potential moderating factors.
Synthesized data across 148 studies comprising 308,849 participants using a random-effects weighted average model.
Extracted participant health variables (baseline health status, cause of death) and study characteristics (follow-up duration, measurement type of social relationships).
Participants with stronger social relationships exhibited a 50% higher likelihood of survival (random-effects weighted OR = 1.50; 95% CI, 1.42–1.59), an effect consistent across age, sex, initial health status, and follow-up length.
Relationship measurement type significantly moderated the association (p < 0.001), with complex social integration demonstrating the strongest protective effect (OR = 1.91; 95% CI, 1.63–2.23) and binary living status demonstrating the weakest (OR = 1.19; 95% CI, 0.99–1.44).

Implication

Meta-analysis reveals increased survival odds among individuals with stronger social relationships, indicating social connections rival established risk factors for mortality.
