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 cholesterol as one of the main variables included in the survey. The original sample contained 170 persons and 148 were alive at the time of examination. Participation rate of sample is 72%. By end of 1988, 35 persons were alive and 71 dead. Excluded were 22 dead before entry. Serum cholesterol was found to be negatively predictive of mortality in both univariate (p < 0.01) and multivariate analysis when triglycerides, 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 cholesterol. Ten persons had serum cholesterol of 160 mg/dl or less and they all died within 10 years from the examination, one of disseminated carcinoma and the rest of non-cancer causes. The strong inverse relationship between mortality and serum cholesterol indicates that this risk factor in old people may be of different nature than in other age groups. Árið 1982 voru rannsakaðir 106 einstaklingar úr tilviljunarkenndu þýðisúrtaki úr Þjóðskrá 1.desember 1981, sem voru 80 ára og eldri og bjuggu á Reykjavíkursvæðinu. Tilskilið var að þeir dveldu ekki á sjúkrahúsi þann tíma sem rannsóknin stóð yfir og vildu taka þátt í henni annað hvort með heimsókn á Rannsóknarstöð Hjartaverndar eða með vitjun í heimahús ef þeir treystu sér ekki til að koma. Heimtur urðu 72%. Konur voru fjölmennari eöa 67% hópsins og meðalaldur 87 ár. Á eigin heimilum bjuggu 65% en 27% á elli- og dvalarheimilum fyrir aldraða. Um helmingur fólksins taldist hafa fulla hreyfigetu, utanhúss sem innan en 15% þurftu aðstoðar með ferðir innanhúss. Meðalfjöldi sjúkdómsgreininga var 5,1 á einstakling en sjúkdómsgreiningum ...
