Summary: The population groups living on islands of Brač and Hvar,
and in continental areas Sinjska Krajna and Srijem, examined during the
period between 1970 and 1971 in the epidemiological investigation, have
been considered as a baseline cohort population for assessing the ageing
process. Epidemiological characteristics of the population, described by
three sets of variables, have been estimated through the factor score
distributions for each of the variable sets and the corresponding
variability for each region. The main differences as well as variability
were found between the island population (characterized to tendency to
overweight, preferably by vegetable oil consumption, lower alcohol intake
and lower blood pressure with higher blood glucose) and the continental
populations (characterized in opposite way). Survival rates and couses od
death during the twenty year period of population groups of islands of Brač
and Hvar, and continental areas Sinjska Krajna and Srijem, were assessed.
Female cohorths show better survival than male cohorts, and island better
than continental areas. In both male and female cohorts a marked gradient
from Hvar to Srijem is shown. In the course of the follow up 5,3% of the
cohorts were without any impairement and disease, wile 11,6% was
permanently ill and handicaped. The age of 80 and more have reached 18,4%
of cohorts on Brač, 17,6% of cohorts on Hvar, 10,4% of cohorts in Sinjska
Krajna, 7,8% in autochtonous Srijem and 5,9% in immigrated Srijem.

Research goals: 1. Epidemiological characterization of the baseline
cohort population at the beginning; 2. Twenty year mortality rate and
causes of death assessed through official health and vital statistics; 3.
Estimation of perceived health ratings based on self-assessment of
disability, impairments, chronic conditions,symptoms ang energy level
through reinterviewing thepopulation after 20 year; 4. Genealogical
aggregation og longevity and ageing without impairement and disease; 5.
Searching for factors of the supposed time-process of autonomy - disease
- impairement - disability - handicap; 6. Enquiring the regional
differences in ageing; 7. Construction of the models for prognosis of
outcomes defined as "living in health and without impairment", "living
disease -as an invalid " and "death". Other information about the project.
