- OBJECTIVE
To investigate gamma-Glutamyltransferase (gamma-GTP) and its related factors in male industrial workers. METHOD: Five hundred and forty male workers without heart disease, diabetes mellitus, renal disease, hepatitis, and other liver diseases were surveyed in October 1998. Blood samples were collected to test for gamma-GTP, total-cholesterol and fasting blood glucose. A self-administered questionnaire survey on life style was also done. RESULTS: The total geometric mean value of gamma-GTP was 30.6 U/L. According to a univariate analysis: age, BMI(body mass index, kg/m2), alcohol consumption, current smoking, stress, diastolic blood pressure, and blood total cholesterol were significantly associated with gamma-GTP(p<0.05). From a multiple regression analysis: BMI, alcohol consumption, current smoking, diastolic blood pressure and total-cholesterol were significantly related to gamma-GTP(p<0.05). Coffee consumption was negatively related to gamma-GTP, but not significantly. CONCLUSION: We recommend that a change in health behavior (i.e. reducing alcohol intake, controlling BMI and not smoking) is necessary to decrease gamma-GTP in male workers.

Abstract

- To estimate the incidence rate of coronary heart disease in Korea, of all residents of the Taegu city aged 25 or above, those who had an acute MI or fatal coronary event between 1 July 1996 and 30 June 1997 were registered. Seven hundreds and eight patients were registered during the study period(685 were identified at hospital and 23 were autopsy cases). Age-standardized annual incidence rate of men in city area was 93 per 100,000(95% CI; 61-142) and 33(95% CI; 16-67) in women(100 in men and 20 in women aged 35-64). The incidence was rapidly increased after age 40 in men, however, in women after age 60. Twenty-eight-days case fatality rate was 45% in men and 47% in women. However, in the age group of 45-59 case fatality rate in women was two times higher than that in men. In conclusion, crude annual incidence rate of CHD in city area was 73 per 100,000 in men and 33 in women. The age-standardized annual incidence of CHD in men(93 per 100,000) was 3.2 times higher than that in women (33 per 100,000) in Korea.

- To identify the drug abuse status and its determinant factors in high school boys in Taegu, the study was performed from April to May, 1995. Study population were selected by cluster sampling method and total 5,665 students replied to the self-administered questionnaire survey(2,207 in academic high school, 3,458 in business high school). The major findings were as follows; The proportion of drinking, smoking experience was 55.0%, 45.8%, respectively, and the proportion of current drinker, current smoker was 27.2%, 27.5%. The drinking, smoking experience rate of second grade students was higher than first grade and it was higher in business high school boys. The proportion of a stimulant, a hallucinogen, hemp leaf cigarets experience was 3.2%, 1.6%, 0.1%, respectively. Drug abuse had significant association with home environment(lower economic status, frequent move, death of father or mother, apart from family), parents environment(parents' indifference, parents' drinking and smoking, etc.), school life(lower school grades, intimate friend's drug abuse, etc.), generous attitude to drug abuse, higher level of stress. Students who replied that the law prohibited immature person(students) from drinking and smoking showed lower drug abuse rate. In multiple logistic regression analysis, second grade students, business high school students, parents' indifference, lower school grades, intimate friend's drug abuse, no recognition of the fact that the law prohibits high school students from drinking and smoking, generous attitude to drug abuse, higher level of stress were significantly related with alcohol abuse and smoking. Other drugs abuse were related with above factors. On consideration of above findings, to prevent students from drug abuse, we have to try together in house, school, and society.

Abstract

- This study was conducted to evaluate the relationship between change in obesity indices and change in serum lipids in adult male workers. Two-hundred-eight adult male workers of an industry in Taegu city were followed-up from 1991 to 1995. Height, weight, circumferences of hip and waist, blood pressure were measured and serum lipids were analysed. Data on life style were obtained using self-administered questionnaires. Mean differences of anthropometric measurements between 1991 and 1995 were as follows; 1.63kg in weight, 3.61cm in waist circumferences, 4.23cm in hip circumferences, 0.52kg/m2 in BMI and -0.021 in WHR. Those of lipids were as follows; 15.09mg/dl in total cholesterol, 20.43mg/dl in triglyceride, 9.40mg/dl in HDL-cholesterol, 2.87 in MI-index(p<0.01) and 350mg/dl in LDL-cholesterol. The changed value of BMI and Katsura index were strongly correlated with that of total cholesterol(r=0.174, p<0.05), the changed value of BMI correlated with that of triglyceride(r=0.374, p<0.01) and the changed value of weight correlated with that of MI index(r=-0.173, p<0.05). The changed value of WHR was significantly correlated with that of total cholesterol(r=0.162, p<0.05), however, was not significantly correlated with HDL-cholesterol, LDL-cholesterol, triglyceride and MI index. The changed value of weight, BMI and Katsura index were correlated with that of triglyceride(r=0.262, p<0.01; r=0.267, p<0.01; r=0.258, p<0.01) and the changed value of MI index(r=-0.143, p<0.05; r=-0.158; r=-0.144, p<0.01), adjusting the pattern of change in life style. The changed values of HDL-cholesterol and MI index between 1991 and 1995 in low WHR group were significantly higher than those in high WHR group(p<0.05, p<0.01), adjusting the baseline value of them. Similar pattern was observed when considering Katsura index. When stratifying by BMI value of 1991, in low BMI group, the changed value of HDL-cholesterol and MI index showed the same pattern as above, however the of triglyceride was statistically higher in obese group than in non obese group(p<0.05). In conclusion BMI might be a better indicator to predict serum lipids change than other obesity indices.
