The relationship between social and community ties and mortality was assessed using the 1965 Human Population Laboratory survey of a random sample of 6928 adults in Alameda County, California and a subsequent nine-year mortality follow-up. The findings show that people who lacked social and community ties were more likely to die in the follow-up period than those with more extensive contacts. The age-adjusted relative risks for those most isolated when compared to those with the most social contacts were 2.3 for men and 2.8 for women. The association between social ties and mortality was found to be independent of self-reported physical health status at the time of the 1965 survey, year of death, socioeconomic status, and health practices such as smoking, alcoholic beverage consumption, obesity, physical activity, and utilization of preventive health services as well as a cumulative index of health practices.

The prospective association of social relationships and activities reported during a round of interviews and medical examinations in 1967-1969 with mortality over the succeeding nine to 12 years was examined for a cohort of 2754 adult (aged 35-69 years as of 1967-1969) men and women in the Tecumseh Community Health Study. After adjustments for age and a variety of risk factors for mortality, men reporting a higher levels of social relationships and activities in 1967-1969 were significantly less likely to die during the follow-up period. Trends for women were similar, but generally nonsignificant once age and other risk factors were controlled. These results were invariant across age, occupational, and health status groups. No association was observed between mortality and satisfaction with social relationships or activities. How and why social relationships and activities predict mortality are discussed and identified as important foci for future research.
