Abstract: Objective : To determine the factors associated with the survival duration of elderly individuals aged 80 years and older.
Methods : Forty three elderly individuals, aged ≥80 years, who had undergone a health check-up in Wara Village (Gujo, Gifu Prefecture) between 1991 and 1995 (baseline evaluation) were followed-up until March 31, 2011. The relationships between survival duration and age, sex, body mass index (BMI), history of hypertension or diabetes, serum total and high-density lipoprotein-cholesterol concentrations, and smoking status were analyzed.
Results : The average age at baseline examination was 81.9 years. On Cox proportional hazards models, there was a significant correlation between survival duration and history of diabetes, but no such association was found for age, sex, BMI, history of hypertension, total and high-density lipoprotein-cholesterol concentrations, or smoking status.
Conclusion : The present study suggests that a history of diabetes is associated with a shorter survival duration in those aged ≥80 years who had undergone health check-ups.
