MORBIDITY AND DISABILITY IN 75 AND 80-YEAR-OLD MEN AND WOMEN - A 5-YEAR FOLLOW-UP

Purpose of this report is to describe the changes that occurred in mor bidity, symptoms of illness and disability of 75- and 80-year-old resi dents of Jyvaskyla, Finland, over five-year period. The study populati on consisted of the elderly residents of the city of Jyvaskyla in cent ral Finland who were born in 1914 and 1910. At baseline (in 1989 and 1 990), 355 (92.9%) persons from the younger age group and 262 (91.9%)fr om the older age group were interviewed and 311 (81.4%) and 230 (80.7% ), respectively, took parr in the physical examination. At follow-up ( in 1994 and 1995), the corresponding numbers were 250 (93.3%) and 148 (88.6%)for the interviews and 217 (81.0%) and 127 (76.0%) for the phys ical examinations. The prevalence of chronic conditions was determined in connection with the medical examinations on the basis of self-repo rt and the respondent's prescriptions and medical information cards. T o measure the occurrence of symptoms, the respondents were asked wheth er during the past 14 days they had suffered from any of 17 listed sym ptoms. Functional capacity was assessed in connection with the intervi ew carried out at the respondent's home in terms of needing help in ac tivities of daily living (ADL). In the baseline examinations, subjects were found to have on average 2-3 diseases. During the follow-up the number of diseases and the proportion of people with co-morbidity incr eased in both age groups. Both men and women had on average 1-2 sympto ms that caused them much trouble, and the number of such symptoms incr eased to some extent during the follow-up. The proportions of those ne eding help increased during the follow-up in all groups and the increa se was most prominent among the women of the older age group. Of those who managed independently with physical ADL (PADL) at baseline, 14.9% - 44.9% reported need of help in at least one task at follow-up. The need for help in PADL was greatest with cutting toe-nails, negotiating stairs, moving outdoors, washing the upper body and in instrumental A DL (IADL) with vacuuming, shopping, handling finances and in the use o f public transport. Successful prevention and postponement of function al disabilities in the elderly population depends not only on the earl y diagnosis of illness but also on identifying even minor signs and sy mptoms of disease and functional limitations, and to focus health care interventions accordingly.
