Predictors of all-cause mortality between ages 70 and 80: the Koganei study.

Abstract The present paper explores predictors of all-cause mortality based on a longitudinal multidisciplinary study of 422 community residents (197 men, 225 women) aged 69–71 years at baseline examination. The 422 subjects were followed up for 10 years (1976–1986), during which time 102 (59 men, 43 women) died. The Cox proportional hazards model was used to examine the effects of baseline variables on a time-dependent 10-year mortality. Body mass showed a U-shaped relationship to mortality in both sexes. Ex-drinking, current-smoking, history of stroke, history of diabetes mellitus, low ADL and ST and/or T changes in ECG had significant and direct effects on mortality in both sexes or either sex. Whereas, level of education, current-drinking, grip strength, visual retention, and serum albumin revealed significantly inverse relationships to mortality.
