In 1982 a multifactorial population health survey of @entity1 aged 80 years and older and living in the community, was carried out. The mortality registry was examined up to the end of year 1988. By this time 67% had died and the mortality was assessed by Cox's regression analysis on serum @entity165 as one of the main variables included in the survey. The original sample contained 170 @entity1 and 148 were alive at the time of examination. Participation rate of sample is 72%. By end of 1988, 35 @entity1 were alive and 71 dead. Excluded were 22 dead before entry. Serum @entity165 was found to be negatively predictive of mortality in both univariate (p < 0.01) and multivariate analysis when @entity1674 , age and smoking were also included (p < 0.01). There was a 0.9% decrease in relative risk for each mg/dl increase of serum @entity165 . Ten persons had serum @entity165 of 160 mg/dl or less and they all died within 10 years from the examination, one of disseminated @entity189 and the rest of @entity5 causes. The strong inverse relationship between mortality and serum @entity165 indicates that this risk factor in old @entity1 may be of different nature than in other age groups.
