摘要: Abstract Purpose A well-established literature has shown that social integration strongly patterns health, including mortality risk. However, the extent to which living in high-poverty neighborhoods and having few ties jointly pattern survival United States not been examined. Methods We analyzed data from Third National Health Nutrition Examination Survey (1988–1994) linked follow-up through 2006 census-based neighborhood poverty. fit Cox proportional hazards models estimate associations between poverty on all-cause as independent predictors joint-effects using relative excess risk due interaction test for an additive scale. Results In model adjusting age, gender, race/ ethnicity, individual-level socioeconomic status, exposure low alone was associated with increased (hazard ratio [HR]: 1.42, 95% confidence interval [CI]: 1.28–1.59) while area of high did have a significant effect (HR: 1.10; CI: 0.95–1.28) when compared being unexposed. Individuals simultaneously characterized by levels had 1.63; 1.35–1.96). results were statistically significant. Conclusions Social remains important determinant
