Social Relationships and Mortality Risk: A Meta-analytic Review
Julianne Holt-Lunstad, Timothy B. Smith, J. Bradley Layton · 2010
사회적 관계가 수명에 미치는 영향을 148편의 연구(30만여 명)로 분석한 메타분석입니다. 사회적 관계가 튼튼한 사람은 살아남을 가능성이 50% 높았습니다. 그 영향은 흡연처럼 잘 알려진 사망 위험 요인에 견줄 만한 크기였습니다.

Background: The quality and quantity of individuals' social relationships has been linked not only to mental health but also to both morbidity and mortality.
Objectives: This meta-analytic review was conducted to determine the extent to which social relationships influence risk for mortality, which aspects of social relationships are most highly predictive, and which factors may moderate the risk.
Data Extraction: Data were extracted on several participant characteristics, including cause of mortality, initial health status, and pre-existing health conditions, as well as on study characteristics, including length of follow-up and type of assessment of social relationships.
Results: Across 148 studies (308,849 participants), the random effects weighted average effect size was OR = 1.50 (95% CI 1.42 to 1.59), indicating a 50% increased likelihood of survival for participants with stronger social relationships. This finding remained consistent across age, sex, initial health status, cause of death, and follow-up period. Significant differences were found across the type of social measurement evaluated (p<0.001); the association was strongest for complex measures of social integration (OR = 1.91; 95% CI 1.63 to 2.23) and lowest for binary indicators of residential status (living alone versus with others) (OR = 1.19; 95% CI 0.99 to 1.44).
Conclusions: The influence of social relationships on risk for mortality is comparable with well-established risk factors for mortality.
