This study was conducted to evaluate the health related behaviors associated with blood pressure, results of liver function and renal function, and anemia indices. Study subjects were 499 male workers who visited to General Health Screening Center of A hospital located in Chonan. Data were collected from March to December 1996. By the questionnaire, the informations of health related behaviors such as, age, smoking and drinking habits, food intake habit, sleeping time, stress were obtained. Height, weight and blood pressure were measured by a trained nurse. The level of total Cholesterol, HDL Cholesterol, triglyceride, fasting blood sugar, glutamate oxaloacetate transaminase(GOT), glutamate pyruvate transaminase (GPT), r-glutamyl transferase(rGTP), blood urea nitrogen(BUN), serum creatinine(Cr), hemoglobin(Hb), hematocrit(Hct), hepatitis B surface antigen were selected as biometric test variables. Statistical analysis, such as t-test, Chi square-test, stepwise multiple regression, multiple logistic regression were performed using SAS package program. There were significant differences in age, systolic blood pressure, total cholesterol, GOT, GGT, BUN, Hb, and Hct between drinkers and non-drinkers, and significant differences in age, body mass index(BMI), systolic blood pressure, diastolic blood pressure, rGTP, BUN, and Hb between smokers and non-smokers . Triglyceride, age, BMI, and HDL cholesterol were found to be positivc independent predictors of blood pressure, but drinking habit(mild drinking group vs. non-drinking group) and pack-year of smoking were negative predictors of blood pressure. Logistic analysis of systolic hypertensive related condition indicated that triglyceride(OR=1.003, 95% CI; 1.000-1.006), total cholesterol(OR=1.008, 95% CI; 1.000-1.016), and pack-years of smoking (OR=0.972, 95% CI; 0.952-0.994) were significantly contribution to dependent variable, Logistic analysis of diastolic hypertensive related condition revealed that age3(≥50 years vs. <40 years) (OR=4.702 (95% CI; 1.919-11.521), age2(40-49 years vs. <40 years) (OR=4.702 (955 CI; 1.919-11.521), triglyceride (OR=1.005, 95% CI; 1.002-1.008), pack-years of smoking(OR=0.972, 95% CI; 0.951-0.993), and meal regularity (yes vs. no) (OR=0.618, 95% CI; 0.383-0.991) were significantly contribution to dependent variable. Triglyceride, total cholesterol, fasting blood sugar, and animal food intake(yea vs. no) were found to be positive independent predictors to BMI, but HDL and stress(yes vs. no) were negative predictors. Logistic analysis of abnormal BMI condition indicated that total cholesterol(OR= 1.013, 95% CI; 1.007-1.020) and HDL cholesterol (OR=0.943, 95% CI; 0.916-0.972) were significantly contribution to dependent variable. BMI, HBs Ag, and the frequency of drinking were found to be positive independent predictors to GOT, but meal regularity(yes vs. no) were negative predictors. Logistic analysis of abnormal GOT condition indicated that HBs Ag(yes vs. no)(OR-6.666, 95% CI; 1.724-25.779), BMI(OR=1.199, 95% CI;1.015-1.416), and meal regularity(yes vs. no)(OR=0.248, 95% CI; 0.096-0.639) were significantly contribution to dependent variable. BMI, and HBs Ag were found to be positive independent predictors to GPT, but meal regularity(yes vs. no) were negative predictors. Logistic analysis of abnormal GPT condition showed that only BMI (OR=1.301, 95% CI; 1.301(1.176-1.440) was significantly contribution to dependent variable. BMI and the frequency of drinking were found to be positive independent predictors to rGTP, but meal regularity(yes vs. no) were negative predictors. Logistic analysis of abnormal rGTP conditionindicated that BMI(OR=1.340, 95% CI; 1.197-1.499), Alc5(abovc 5 times/week vs. non-drinking) (OR=21.733, 95% CI; 3.671-128.684), Alc4(3-4 times/week vs. non-drinking) (OR=4.533, 95% CI; 1.463-14.049), Alc3(1-2 times/week vs. non-drinking) (OR=3.918, 95% CI; 1.406-10.916), and meal regularity(yes vs. no) (OR=0.405, 95% CI; 0.221-0.740) were significantly contribution to dependent variable. BMI and age were found to be positive independent predictors to BUN, but stress(yes vs. no) and pack-year of smoking were negative predictors. Logistic analysis of abnormal BUN condition indicated that only age3(≥50 years vs. <40 years) (OR=4.808 (95% CI; 1.307-17.676) was significantly contribution to dependent variable. BMI was found to be positive independent predictors to Hb and Hct, respectively, but regular exercise(yes vs. no) was negative predictors to Hb and Hct, respectively. With above results, it was found that age, BMI, level of serum triglyceride, and level of serum total cholesterol were significantly associated with hypertension and that BMI was significantly associated with abnormal results of liver function tests and especially the frequency of drinking was associated with abnormal rGTP. Also the workers with meal regularity habits, compared to those with meal irregularity habits, were lower prevalence of hypertension and abnormal liver function tests, therefore the meal regularity habits seem to be reflected good health related behaviors.

This study was conducted to evaluate blood pressure associated with body mass index and blood lipids. Study subjects were 3,076 persons (1,623 males and 1,453 females) who visited to General Health Screening Center located in Chonan. Data were collected from 2001 to 2003. Height, weight and blood pressure were measured by a trained nurse. The level of total cholesterol, HDL cholesterol, triglyceride, and fasting blood sugar were selected as biometric test variables. Statistical analysis, such as t-test, simple correlation, and stepwise multiple regression were performed using SAS package program. The mean (standar deviation) of age, BMI, systolic blood pressure, diastolic blood pressure, fasting blood sugar, triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol in study subjects were 48.4 ±11.8 years, 23,7 ± 3.2 kg/m^(2), 124.6 ± 16.3 mmHg, 80.9 ± 10.7 mmHg, 97.6 ± 24.9 mg/㎗, 154.4 ± 105.6 mg/㎗, 203.2 ± 39.2 mg/㎗, 51.0 ± 12.8 mg/㎗, and 121.8 ± 35.6 mg/㎗, respectively. In multiple regression analysis of BMI and blood lipids on systolic blood pressure after controlling for confounders (age, sex, and fasting blood sugar), BMI, HDL cholesterol, and triglyceride were found to be significant positive independent predictors of systolic blood pressure. In multiple regression analysis of BMI and blood lipids on systolic blood pressure after controlling for confounders (age, sex, and fasting blood sugar), BMI, triglyceride, HDL cholesterol, and LDL cholesterol were found to be significant positive independent predictors fo systolic blood pressure. With above results, it was found that BMI and blood lipids were significantly associated with blood pressure.

전자부품 제조업 근로자들의 시력변화에 대한 연구

이용만,안규동,이성수,함정오,김화성,리갑수,이병국 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.2

근접작업이 시력약화의 원인이 될 수 있는가를 알아보기 위하여 전자부품을 제조하는 2개 사업장에서 1991년에서 1993년까지 입사한 근로자들 중에서 근접작업으로 인정되는 마이크로칩을 조립하는 근접작업자 306명을 조사군으로, 대조군은 세탁기 타이머 및 일반 기계기구를 조립하는 작업자 154명, 계 460명을 선정하였다. 이들 대상자는 1991년 입사자는 1993, 1994, 1995년 시력을 조사하였으며, 1992년 입사자는 1993, 1994, 1995년 3년동안 조사를 하였으며, 1993년 입사자는 1994, 1995년 2년간 시력을 조사하였다. 대상자 중에서 입사시 안경을 착용한 근로자는 82명(17.8%)이었다. 따라서 남자 근로자와 안경착용자를 제외한 여성 근로자들 335명만을 추적 조사하여 다음과 같은 결론을 얻었다. 조사군에서 입사시 시력 1.0 이상이었던 근로자의 분포는 취업 1년 후 약 25-35% 정도 감소하였으며, 2년후에는 약 40-60% 정도의 감소를 나타내었고, 3년 후 약 50-65% 정도로 감소하였고 4년후에는 약 65% 이상 감소하였다. 그러나 대조군에서는 1.0 이상의 시력을 보였던 근로자들의 비율이 취업 1년 또는 2년 후 15-30%의 감소를 보이고 있으나 그 이후에는 큰 변동이 없었다. 이들의 시력변화를 근무년수에 따라 알아보기 위하여 조사된 시력을 순위변수로 하여 Kruskall-Wallis 검정을 시행한 결과 조사군, 대조군 모두에서 근속년수에 따른 순위의 합의 평균이 년차적으로 유의하게 감소하였으나, 입사시부터 근속년수에 따른 조사군과 대조군과의 순위합의 평균에 의한 시력차 비교에서 입사시 조사군의 순위합의 평균이 유의하게 높았던 것이 근무기간에 따라 대조군의 평균이 높아지면서 통계적 유의성이 없고 대체적으로 1년 이후부터 변화가 적은 것으로 나타나 근접작업으로 인한 시력약화를 추정할 수 있었다. This study was carried out to investigate that the close distance works were associated with decreased visual acuity. 306 workers were subjects who had been recruited from 1991 to 1993 in two electronic parts manufacturing factories, and 154 workers were controls who had been employed from 1991 to 1993 in launder machine timer and general machine assembly factories. Subjects who had been employed in 1991 and 1992 were follow up from 1993 to 1995, and subjects who had been employed in 1993 were from 1994 to 1995. The male workers as well as glasses wearing workers were excluded. Only 335 female workers were followed up to study the change of visual acuity. The results were as follows; The rate of workers with visual acuity over 1.0 at recruit year in subjects group was decreased about 25-35% after 1 year, 40-60% after 2 years, 50-65% after 3 years, and 65% after 4 years. While, the rate of workers with visual acuity over 1.0 at recruit year in control group was decreased about 15-30% after 1 or 2 years, and there was no more additional visual acuity reduction after then. Kruskall-Wallis test was performed to investigate the change of visual acuity in subject and control group by work duration. The means scores of ranks in both group were significantly decreased by work duration. The mean scores of ranks in subject group at recruit year were significantly higher than those in control group at recruit year, but these differences were disappeared after 1 year work. Therefore, this suggest that close distance workers may be affected their visual acuity.

리갑수,황보영,김용배,김화성,함정오,이성수,안규동,이병국,허정,Lee, Gap-Soo,HwangBo, Young,Kim, Yong-Bae,Kim, Hwa-Sung,Ham, Jung-Oh,Lee, Sung-Soo,Ahn, Kyu-Dong,Lee, Byung-Kook,Hur, Jung 대한예방의학회 1996 예방의학회지 Vol.29 No.4

연 업종별 보건관리 대행기관에 의해 근로자의 보건 관리를 하고 있는 5개 연 축전지 회사의 전체 근로자들 중 1995년에 일반 건강진단 및 특수 건강진단을 동시에 시행한 전체 1,919명의 근로자 중에서 C(건강관리 상 계속 관찰이 필요한자)와 D(유소견자)의 판정을 받은 365명의 근로자들을 대상으로 하여 이들 중 퇴직자 35명, 조사 기간중 출장, 휴직 및 야간 근무자 8명, 그리고 조사에 응하지 않은 근로자 29명 등 총 72명을 제외한 293명을 대상으로 설문 및 1995년도 일반 및 특수 건강진단 결과표를 통하여 건강진단 결과에 따른 사후관리 조치실태 및 관련 요인들을 조사하였다. 결과를 요약하면 다음과 같다. 1. 요주의자 이상근로자의 86%가 건강진단결과표를 받았으나 이에 대한 교육설명이 제대로 이루어지지 않았고, 자신의 건강진단 결과를 잘 알고 있지 못하였다. 2. 사후관리 조치가 있었던 근로자는 23%로 낮았으며, 사후관리조치의 내용은 단순한 추적관찰이 가장 많았다. 3. 조사대상 근로자들은 현재의 건강진단은 필요하지만 형식적이라고 하였다. 4.사후관리 조치의 유무를 피설명변수로 한 로지스틱 회귀분석에서 유의한 설명 변수는 건강진단 결과에 대한 설명의 유무뿐이었다. To evaluate the follow-up management state and related factor of lead battery workers in periodic health examination as part of program of group occupational health service, author studied 293 workers with questionnaire on knowledge of results and follow-up management state and related factors, and compared the responses to their periodic health examination result charts. The results were as follows: 1. 252(86%) workers responsed that they had received the health examination result chart, but only 116(39.6%) workers responsed that they had been educated or explained about the results of health examination, and 11(57.9%) workers among 19 workers with non-occupational disease D, 101(44.3%) workers among 228 workers with non-occupational disease C, and 19(28.4%) workers among 67 workers with occupational disease C knew accurately their health examination results. 2. 78(24.8%) of the workers responsed that they had follow-up management, and contents of follow-up management were follow-up(36.6%), out-patient treatment (31%), change worksite(8.5%), temporary retirement(7.0%) and others(16.9%). 3. Most of the workers responsed that the health examination were necessary, but three-fourths of the workers responsed that the health examination had been superficial or that they didn't know. 4. In this study, follow-up management show significant association with only explanation or education about health examination result chart.
