Abstract

|
Population growth, accompanied by industrial and urban evolution, has caused various major health problems, which is an increasingly evident trend in man industrialized nations.
Korea has also faced a significant change in disease pattern that the leading causes of disease altered from infections to various chronic degenerative diseases.
Generally, chronic degenerative diseases require longer period of morbidity and usually accompany permanent sequel including severe limitation of physical activity. New technologies in preventive medicine have significantly deterred the development of such chronic diseases.
Measuring and determining exactly the extent of morbidity among the total population is practically an impossible task; however, a properly conducted sample survey should result in meaningful data which the study requires. Among the sources from which such information can be obtained is the medical insurance system.
The primary purpose of this study was to determine the epidemiologic characteristics of Korean population by analyzing the National Federation of Medical Insurance´s hospital admission data during 1985-1987 period. This study focuses on the following major chronnic diseases:
Malignant neoplasms (140-208)
Diabetes malitus (250)
Hypertensive diseases (401-405)
Heart diseases (414, 416)
Cerebrovascular diseases (430-438)
Liver diseases (571)
Chronic renal failure (585)
Following are highlights of the findings:
1. Total number of Industrial Establishments Medical Insurance beneficiaries was 12,214,000 in 1985,13,294,000 in 1986 and 14,971,000 in 1987, or 29.7, 32.0, and 35.6 in 1985, 1986, and 1987, respectively, expressed in "per 1,000 ratio."
Among the population under 20 years of age, female had more medical insurance coverage than mal
population; however, in the age group of 20 years and above, male had more insurance.
2. Total admissions to hospital increased consistently throughout the period and the proportions of chroni diseases to the toal admissions also showed increase. The proportions were 21.7%, 22.5%, and 23.6" in 1985, 1986, and 1987, respectively. The proportions for male patients only were as high as twice those of female alone.
3. The proportions of major chronic diseases to the total chronic diseases were 44.6%, 46.0%, and 47.0Q in 1985, 1986, and 1987, respectively.
4. The admission rates for major chronic diseases among medically insured population w ere 5.89%, 6.17%. and 6.93% in 1985, 1986, and 1987, respectively. In the age group of 70 years and above, the admission rates were as high as 41.94% in 1985, 45.78% in 1986, and 51.66% in 1987.
5. The standardized official statistics for the admission rates among medically insured population mentioned above were even higher at 6.00%, 6.22%, and 7.65% in 1985, 1986, and 1987, respectively.
6. The admission rates for malignant neoplasms were noticeably higher than those for other disease The ratios of malignant neoplasms to other major diseases were 40.8%, 41.0%, and 42.2% in 198 , 1986, and 1987, respectively.
7. While the odds ratio of malignant neoplasms was 1.92% and that of liver diseases was 2.08%, the same for all other diseases was below 1.0% during the entire three year period. It was also revealed the male,is more vulnerable to malignant neoplasams and liver diseases, but female seems more suscep- table to other diseases.
