- The purpose of this study was to evaluate the relative importance among various biological and environmental factors on refractive errors. Various factors such as diseases, health related behavior such as drinking, smoking and exercise, as well as dietary factors were considered as a possible determinant. Surveys of 492 residents over 20 years of age in Kuri city were conducted during 1998. The survey included a refractive error test adopting a autokerato-refractometer, dietary survey using a 24 hour recall method, disease survey including blood and other diagnosis tests, and a health behavior survey using questionnaires with variables of smoking, drinking, and exercise. A stepwise logistic regression analysis was adopted to analyse the relative importance among independent variables of health behaviors, disease, and dietary factors on ametropias. As a result, in the case of myopia, liver dysfunction appeared to be the most important factors followed by the health related behavior of smoking and exercise as the second most important factors. Nutrient factors such as carotene and protein appeared to be the third most important factors. Similar results had been shown in the case of the hyperopia. In summary, liver dysfunction and the health related behaviors of drinking and smoking appeared to be more influential factors on abnormal eye sight of myopia and hyperopia than dietary factors.

- Cardiovascular disease is very prevalent in Korea, and many risk factors, if properly identified are possibly corrected. However, the study results on prevalence and distribution of risk factors may not be reliable while the risk factors of disease are always issued on health promotion projects conducted recently in a community. The subjects of this study were 854 adults who participated in the health and nutrition survey in a community. They were aged between 20 and 69 and sampled representatively. This study intended to estimate the prevalence and the distribution of risk factors of cardiovascular disease such as hypertention, diabetes mellitus, hypercholesterolemia, and obesity. Systolic blood pressure and diastolic blood pressure levels were estimated at 123.9+/-2.2mgHg(men), 117.9+/-1.7mgHg(women), and 80.4+/-1.5mg(men), 74.9+/-1.1mgHg(women), respectively. Glucose level was estimated at 99.1+/-2.3mg/dl in men, and 95.7+/-1.7mg/dl in women. The estimated level of total cholesterol and HDL-cholesterol were 183.4+/-3.8mg/dl(men), 181.7+/-3.1mg/dl(men), and 122.0+/-4.5mg/dl (women), and body mass index was estimated at 24.0+/-0.4kg/m2 in men and 23.9+/-0.4kg/m2 in men and 23.9+/-0.3kg/m2 in women. The prevalence of hypertension was 20.5% for men, and 14.4% for women. The prevalence of diabetes mellitus was estimated to 6.9% for men, and 6.1% for women. The estimated prevalence of hypercholesterolemia was 3.8%(men), 3.9%(women). The rate of obesity was estimated to 28.5%(men), 28.4% (women), respectively. The levels of blood pressure, glucose, and cholesterol were higher in men than in women in almost all the almost ate groups. The prevalence of hypertension for men is about 20%. It was found that the prevalence of diabetes mellitus for males aged between 40 and 59 was rapidly increased. The risk factor with highest prevalence was obesity, and hypertension and diabetes mellitus were the second and third most prevalent.
