This study was conducted in order to observe descriptive epidemiological findings and causes of impairment conditions in the rural population of Korea, and to present, on the basis of these observations and the literature, the principles of the necessary control measures.
The total number of subjects in the study was 27,172, all family members of 4,174 households. The study population was located in the 81 counties, out of a total of 138 counties, where the college students conducted service activities during the summer of 1974. In each village area where these service activities were conducted, one household per student interviewer was randomly selected. Student interviewers were instructed on the contents of the questionnaire prior to the survey. Each student interviewed one household.
The main contents of the questionnaire form included address, name, sex and age of each family member, present impairment conditions, if any, of each family member; such as impairment of extremities or the spine, blindness in one or both eyes, deaf-mutism deafness in both ears, cleft lip, and others. In cases of current impairment, the nature of the conditions, age of onset, causes, and labour force loss were recorded.
The crude prevalence rate for all types of impairment conditions was 739.7 per 100,000.
The crude prevalence rate for impairment of the extremities was 379.1 per 100,000; and the causes were poliomyelitis, stroke, accidents, injury due to war operation, and other diseases.
The crude prevalence rate for impairment of the spine was 33.1 per 100,000; and causes were accidents, injury due to war operation, congenital, and other diseases.
The rates of permanent labour force loss were 39.9% for impairment of the extremities and 33.3% for impairment of the spine.
The crude prevalence rate for blindness in both eyes was 84.6 per 100,000; and the causes were foreign bodies accidentally entering the eye and adnexa, accidents caused by pircing objects, ophthalmic diseases, senility, congenital, and other diseases.
The crude prevalence rate for blindness in one eye was 58.9 per 100,000; and the causes were foreign bodies accidentally entering the eye and adnexa, accidents caused by piercing objects, ophthalmic diseases, congenital, and other diseases.
The crude prevalence rate for deaf-mutism was 73.6 per 100,000; and the causes were cogenital and other diseases.
The crude prevalence rate of deafness in both ears was 95.7 per 100,000; and the causes were senility, diseases of the ear, congenital, and other diseases.
The crude prevalence rate for cleft lip was 11.0 per 100,000; and the cause was congenital. This rate might be lower than the actual rate because the cases who had already received plastic surgery were excluded.
For each impairment condition, frequency by current age, provincial lacality and sex, frequency ratio by age of onset, relative frequency by causes, and rates of labour force loss by causes were also reported.
The estimated annual average incidence rate(28.4 per 100,000) for impairment of the extremities due to poliomyelitis in the age group 1-9 during 1959-1973, the estimated annual incidence rate(1.3 or 1.8 per 1,000) for impairment of the extremities due to stroke in the over 30 age group, the estimated annual incidence rate(2.3 or 3.2 per 1,000) for stroke in the over 30 age group, the estimated annual mortality rate(1.7 or 2.4 per 1,000) for strock in the over 30 age group, and the principles of control measures for each impairment condition were also presented.
