Cross-cultural analysis of longevity among Swedish and American elders: the role of social networks in the Gothenburg and Missouri longitudinal studies compared

This paper reports the results of a cross-national comparison of the ‘H70’ longitudinal study of elders in Gothenburg, Sweden, with the ‘Rural Missouri Elders’ longitudinal study in Missouri, USA. Analysis of the combined data sets focused on the question of how longevity was affected by culturally divergent forms of social network participation. The H70 study was a representative, systematic 3/10 sample of 70-year-old (in 1971) men and women living in Gothenburg. Follow-up data was gathered when the respondents were 75, 79, 81, 82, 83, 85, 88, 90 and 95 years of age. Face-to-face interviews and physical medical examinations were the major source of data. The Missouri study involved a representative cluster proportional-to-size sample of all rural Missourians 65 years of age and older. Face-to-face interviews were conducted in 1966, 1974 and 1987. Logistic regression and cross-tabular analyses revealed that social networks were important predictors of longevity for both samples. However, marital status and participation in formal organizations predicted longevity for the Americans, whereas contact with children emerged as the predictor variable for the Swedes. Specific functions of the different network patterns in the two countries are discussed.
