Relation of social network characteristics to 5-year mortality among young-old versus old-old white women in an urban community.
This study examines age-related differences in the association between social network characteristics and mortality for aged white women.
Subjects include a community-dwelling sample of white women aged =65 years (n=806), who lived in northeast Baltimore, Maryland, in 1984.
Three characteristics of social networks were measured :
availability of network resources ;
contact with network resources ;
and integration into the neighborhood.
The association of social network with 5-year mortality was examined with a proportional hazards model adjusting for perceived health status, impairment in physical activities of daily living, number of chronic conditions, and years of education.
Analyses were stratified by age (65-74 years, =75 years).
Elements of social network contact and neighborhood integration were associated with reduced mortality among women aged =75 years, but not among women aged 65-74 years.
In the =75 years group, women who had no contact with children, friends, and group organizations showed hazard ratios (95% confidence intervals (Cl)) of 3.1 (1.2-7.5), 2.2 (1.0-4.9), and 2.8 (1.2-6.5), respectively.
Women who had lived ¾10 years in the neighborhood and women who had no interaction with local merchants showed hazard ratios of 2.5 (95% Cl 1.3-4.8) and 2.2 (95% Cl 1.2-3.9), respectively.
Thus, both age and specific aspects of network structure were found to influence the association between social networks and mortality in elderly women.
