Studies on obesity in health and diseases, eating habits and daily activities and body fat amount in healthy peoples in Korea were carried out and following results were obtained.
A. Epidemiological Studies.
Incidences of obesity in 3, 400 cases(2, 512 cases of male, 888 cases of female) of apparently healthy persons, in 803 cases of hypertension, in 95 cases of diabetes mellitus and in 377 cases of pulmonary tuberculosis were studied.
1. Incidences of obesity(acording to Sub´s criteria) in apparently healthy male were 4.9% in the age group of twenties, 8.9% in the thirties, 11.7% in the fourties and 10.1% in the fifties and in female were 4.9% in the age group of twenties, 19.9% in the thiries, 33.3% in the fourties and 31.8 % in the fifties. Incidences of obesity were increased gradually according to the age in both sex until the fourties and slightly decreased in the fifties. Incidence of obesity was higher in female than male after age of thirties.
2. Incidences of hypertension were increased according to the body fatness in both sex. Incidences of hypertension in obesity were 42.9% in male and 23.0% in female but in emaciation, they were 16.9% and 10.3% respectively.
3. Incidences of obesity were higher in hypertension and diebetes mellitus and lower in pulmonary tuberculosis than apparently healthy persons.
B. Studies on eating habits and daily activities.
Eating habits and daily activities in 485 cases of apparently healthy Koreans (257 cases of male and 228 cases of female) were studied by questionnaire.
1. In Korean people, appetite were well preserved(79.0%) and they liked any kind of principal food (39.8%) or rice diet (36.4%) and liked vegetables (55.8%) than meat (39.2%). The cases which like hot spicy food was 37.2% of cases, salty food 28.9% and sweet food 42.5%.
2. In obese people, appetite and amount of food were increased and they liked any kind of principal food, meat and bean-curd(tooboo). Frequencies of food intake, salty food, hot food, sweet food and exercise were not related with the grade of fatness.
3. In emaciated people, appetite and amount of food were decreased and they liked rice diet and vegetables.
C. Studies on total body fat amount and skinfold thickeness.
Total fat amount and skinfold thickeness by Lange skinfold caliper were studied in 1092 cases of apparently healthy Koreans(849 cases of male, 243 cases of female).
1. Total body fat amount were increased according to the grade of body fatness. Total body fat amount in obese people were 24.6% of body weight in male and 33.1% in female.
2. Total body fat amount, skinfold thickness (of arm, shoulder, abdomen, lumbar region and average) and body weight were well correlated with the grade of fatness by hight-weight table. The skinfold thickeness of scapular area was the most significant correlationship with the grade of fatness in skinfold thickness of 4 areas.
