OBJECTIVES
To determine the relations between seven blood lipids such as total cholesterol(TC), triglyceride(TG), HDL-cholesterol(HDL), LDL-cholesterol(LDL), apolipoprotein A-1(Apo A1), apolipoprotein B(Apo B) and lipoprotein(a)(Lp(A)) and the coronary heart diseases(CHD), the quantitative techniques of meta-analysis were applied to studies of blood lipids and CHD in Koreans. METHODS: We searched the Korean and the English literature published from 1980 to August, 1997 by manual search and bibliography review. Information on sample size, study design, participant characteristics(gender, age) and blood lipid levels were abstracted by reviewers using inclusion criteria. Estimates of the effect sizes of blood lipid levels on CHD in Koreans and corresponding 95% confidence intervals were calculated using random-effect models. RESULTS: We identified 16 case-control studies to apply meta-analysis. The overall effect sizes for CHD were 20.3(95% CI : 14.23-26.22) in TC, 24.8(95% CI : 12.6-36.86) in TG, 15.16(95% CI : 3.99 - 26.33) in LDL, -3.48(95% CI : -5.79 - -1.17) in HDL, -9.78(95% CI : -16.98 - -2.58) in Apo-a1, 17.88(95% CI : 9.72 - 26.05) in Apo B and 18.95(95% CI : 17.88 - 20.02) in Lp(a). CONCLUSIONS: Our results suggested that seven blood lipids were significantly associated with CHD in Koreans. Well-designed and prospective studies between blood lipids and CHD in Koreans should be performed.

AbstractAbstract PDF
To find the association of perception of health status with lifestyle of different ethnic groups living in north-eastern part of China, a cross-sectional questionnaire survey was done by 10 local health workers for 375 Korean immigrants and 217 Chinese whose age was 30 years old or more. Because Korean immigrants showed higher mortality than Chinese, we expected to find significant lifestyle related with perception of health status which was known to be a predictor of mortality by different ethnic groups. The results were as follows: 1. We found that 59.7% of Yanbian Koreans and 42.9% of Yanbian Chinese felt unhealthy (p=0.000). 2. For Yanbian Koreans, significant variables associated with perception of health status were selected through logistic regression analysis and they were sex; female to male with an OR=2.45 (95% confidence interval[CI]: 1.06, 5.64), prevalence of chronic illness with an OR=8.48 (95% CI: 4.62, 15.56), amount of meal; small or moderate to full with an OR=2.67 (95% CI: 1.40, 5.09), preference of spicy food with an OR=1.78 (95% CI: 1.04, 3.04), and less amount intake of vitamin B2 with an OR=2.29 (95% CI: 1.33, 3.93). 3. For Yanbian Chinese, significant variables associated with perception of health status were prevalence of chronic illness with an OR=4.97 (95% CI: 2.11, 11.68), history of taking ginseng with an OR=3.72 (95% CI: 1.33, 10.43), and less intake of vitamin C with an OR=0.18 (95% CI: 0.07, 0.46). In conclusion, sex, presence of chronic illness, dietary habit, and amount of vitamin- B1 intake were associated with perception of health status in Yanbian Koreans. Presence of chronic illness, experience of ginseng intake, and amount of vitamin C intake were associated with perception of health status in Yanbian Chinese. To prove cause-effect relation between perception of health status and lifestyle, further study is needed for these different ethnic groups.

AbstractAbstract PDF
To find the medical insurance utilization of workers when suffering from low back pain, an analysis was made toward the data of medical insurance benefits matched with the general characteristics of 10,183 workers, who were registered continuously from 1993 to 1995 at a medical insurance cooperation for industrial workers. The results were as follows; 1. The period prevalence of the medical insurance utilization for low back pain for 3 years from 1993 to 1995 was calculated as 17.1% for male workers and 19.4% for female workers. Most common cause of utilization was other dorsopathies including the herniation of lumbar discs. 2. The utilization rate increased significantly as the present age and the age joining the company got older(p<0.001). As the duration of employment got longer, the utilization rate of the male showed the tendency to increase and that of the female increased significantly(p<0.05). Among male workers employed at cement and concrete manufacturing companies showed higher utilization rate and among female laborers showed significantly higher utilization rate than clerical workers(p<0.01). 3. Annual utilization rate for low back pain didn't show any difference, but the portion of other dorsopathies among cause of utilization showed the tendency to increase from 1993 to 1995. 4. The mean number of claims for outpatient medical care for low back pain differed significantly by age, working duration, type of industries, income level(p<0.05), and the mean of total visiting days for care of low back pain differed siginificantly by working duration. In conclusion, considering the fact that the medical insurance utilization for low back pain increased annually and other dorsopathies including the herniation of dorsopathies were increasing, an effective preventive or management program for low back pain toward worker employed at industries were required.

AbstractAbstract PDF
This study was performed to find the prevalence and the associated risk factors with low back pain(LBP) of the staffs in a university at Kwang-ju city. The data were collected by a questionnaire including SDS(Self-rating depression Scale) battery from September 1st to October 15th, 1996. The results were as follows; 1. The prevalence rate of LBP during lifetime was 73.1%, 53.1% for the last one year, and 23.6% for the last one week. 2. Statistically significant factors related to LBP during lifetime were sex and satisfaction with job. Sex, smoking, alcohol drinking, occupation, work posture, forward bending of trunk and satisfaction with job were selected as significant factors related to LBP during the last one year. The significant determinants related with LBP during the last one week were sex, smoking, alcohol drinking, occupation, forward bending of trunk and satisfaction with job. 3. Through the analysis of self-rating depression scores according to LBP during lifetime were selected to be female(OR=2.63, 95% CI: 1.08~6.40), dissatisfaction with job(OR=2.16, 95% CI: 1.16~4.15), those for the last one year were chosen to be female(OR=2.30, 95% CI: 1.03~5.12), forward bending of trunk(OR=2.18, 95% CI: 1.26~3.79), dissatisfaction with job(OR=1.84, 95% CI: 1.06~3.21), and those for the last one week were female(OR=3.00, 95% CI: 1.17~7.69), forward bending of trunk(OR=2.85, 95% CI: 1.38~5.88). In conclusion, for effective prevention of the LBP at work site, appropriate improvement of work posture and various psychological factors should be considered.

AbstractAbstract PDF
To evaluate the health risk of the workplace environment of a general hospital toward the hospital workers, a questionnaire survey on the perception of risk at the workplace environment and environmental measurements at 27 locations with 240 workers in the hospital were made from October 25th, 1993 to October 30th, 1994. The results were as follows; 1. By the environmental measurements, 86 workers(36%) were found to be exposed to poor or harmful degree of general illumination, 193 workers(80%) were exposed to poor or harmful local illumination, 34 workers(14%) were exposed to poor or harmful degree of thermal condition and l80 workers(75%) were exposed to poor or harmful noise level, but nobody was exposed to poor or harmful dust and toluene concentration. Also nobody was exposed to poor or harmful level of radiation or anticancer/antibiotic agents. 2. The subjective perceptions on the environmental conditions felt by the workers were different from the objective findings by the environmental measurements. The workers underscored the poor illumination state and overscored the dust concentrations. Also workers oversensitized about the thermal condition, the noise level, the radiation level, the toluene concentration and anticancer/antibiotic agents. 3. The sources of noise were the dialogue(179 workers) and the office instruments(131workers). The sources of dust came from the clothes(108 workers) and the building materials(79 workers). 4. The questionnaire survey showed that the 28 workers were exposed to poor or harmful level of the antibiotics, 10 workers to alkali or acid and 6 workers to drug dust in the pharmacy but the above findings could not be proved by the environmental measurements.

AbstractAbstract PDF
This study was to examine the association of the health-related behaviors and subjective symptoms with smoking. Data were collected by questionnaire survey during regular health examination from Mar. 23 to Mar. 31, 1992 for 1,615 male freshmen of a university in Kwangju City. The results obtained were as follows; 1. Among the freshmen, 26.9% reported that they were smokers. 69.4% for smokers started smoking for the recent 4 years, and 63.4% for smokers smoked 10 cigarettes or more a day. 2. Meal regularity, meat eating, use of coffee or tea and alcohol drinking were positively associated with the status, the duration and the amount of smoking while the vegetable preference was negatively associated with the status and the duration of smoking. 3. There was no evidence of familial aggregation in smoking status except that of siblings. 4. Respiratory symptoms like cough or phlegm, dyspnea were positively associated with the status, the duration, and the amount of smoking. General symptoms like chest pain, fatigue, back pain, facial edema, and weight loss were positively associated with the duration and the amount of smoking. Other symptoms like headache, dizziness, and myalgia were not associated with smoking. 5. In multivariate' logistic regression analysis, cough or phlegm, dyspnea, chest pain, facial edema, and back pain were related to smoking status.

AbstractAbstract PDF
Forty one male workers employed in an underwater construction field were surveyed in the viewpoints of epidemiological analysis of decompression sickness (caisson's disease). Nineteen out of the entire forty one workers have been, or had been suffering from decompression sickness (as 46.3% of incidence rate) after decompression. The results obtained were as follows: 1. There was a significant relation between duration of work and incidence of disease. 2. Type II (severe type) comprised majority of cases (16 cases, 84.2%) despite any significant correlations were not present between severity types and recompression times. 3. Most frequently cited symptoms were lower limb pain (89.5%), upper limb pain (79.0%), pruritus (68.4%) and so on, however, 10% of patients complained of neurological symptoms. 4. There were not any significant correlations between incidence and worker's age or relative body weight.
