공중보건 일반의사들의 업무수행 정도와 진료, 예방 및 보건증진 사업 수행에 필요한 기본적인 수기의 수행능력을 평가하고 그들의 업무 수행능력을 향상시키기 위한 교육 개선 방안을 마련하기 위하여 1982년과 1983년에 배치된 공중보건 일반의사들 가운데 남부 4개도(경북, 경남, 전북, 전남)에서 출신학교별로 비슷한 비율로 120명을 무작위로 뽑아 1984년 1월 9일에서 2월 10일 사이에 설문지를 이용한 집단면담을 하였다. 면담에 응한 97명 가운데 본 조사에 필요한 자료를 제시할 수 있었는 86명으로 부터 얻은 자료를 분석하였다. 보건지소의 진료실적은 2종 보험실시 지역이 1일 평균 $30{\sim}40$명으로 환자가 많으나 그외 지역은 $3{\sim}4$명으로 매우 저조하였다. 또한 예방 및 보건증진사업을 적극적으로 추진한다고 답한 사람은 조사대상자의 2%에 불과했다. 63가지 기본적인 임상수기 가운데서 자신있게 할 수 있다고 한 사람이 50%이상인 것은 근육주사, 정맥주사, 외상치료와 같이 간단한 것으로 12가지에 불과했고 임산부관리, 응급환자처치, 예방 및 보건증진 사업등에 필요한 수기에 자신이 있는 사람은 10%도 못 되었다. 국립보건원에서 실시하고 있는 공중보건 일반의사들의 실무교육이 현지 사정과 맞지 않는것이 많아 실무에 큰 도움이 안 된다고 했으며, 도립병원이나 지방 종합병원에서 받은 임상수련이 실무에 많은 도움이 된다고 한 사람은 38.8%였으며, 별도움이 안된 이유 가운데 전문의가 없거나 있어도 무관심하여 수련지도가 부족한 탓이라고 한 사람이 48.4%로 가장 많았다. 공중보건일반의 실무교육은 교육내용을 실무종사자들의 의견을 수렴하여 현지 사정에 맞도록 개선해야할 것이며, 실무종사자들 가운데 유능한 사람을 강사로 활용하고, 국립보건원에 모아 교육시키는 것보다 전국을 몇개의 지역으로 나누어 지방에서 교육을 시키는것이 효과적일 것이다. 임상실습은 4개월이 적당할 것으로 생각되며, 수련기간 동안에 필수적으로 익혀야 할 수기를 수첩으로 만들어 실습사실을 지도전문의에게 확인 받게하며, 보건사회부에서는 수련지도에 관한 지침을 마련하여 수련병원에 배부하고 수련상황을 평가하도록 한다. 최소한 기본 4과에 전문의를 갖춘 병원을 수련병원으로 선정하여야 할 것이다. 공중보건 일반의사들이 현지에서 당면하는 문제해결을 도우고 사업추진을 위한 동기를 유발하기 위해 보수교육이 필요하며 이를 위해 보건사회부는 재정 및 행정적 지원을 하는 것이 좋겠다. 도를 몇개지역으로 나누어 지역마다 지도위원회를 구성하여 공중보건 일반의사들을 순회지도 하고 자문에 응하도록 하는 것이 좋을 것으로 생각된다. The activities of general physicians (GPs) in health subcenters and their competency for clinical skills were assessed to develop a scheme to improve the training program. One hundred-twenty GPs in southern four provinces (Kyungpook, Kyungnam, Chunpook, Chunnam) were randomly selected and 97 were interviewed between January 9 and February 10, 1984. Of the 97 GPs, 86 provided all the information we requested. Average number of patient visits per health subcenter in a day was 30-40 in the demonstration project area for the class II medical insurance whereas it was 3-4 visits in other area. The interviewees were asked to rate their competency in 63 clinical skills. The skills in which over 50% of the interviewees rated themselves competent were only 12 items including IM injection, IV injection, wound dressing, etc. Less than 10% of the interviewees rated themselves competent in such skills as maternal health care, emergency medical care, preventive and promotive health services. Most part of the training program of the NIH for the GPs were not applicable to their field work as the training contents were unrealistic. Clinical training at a local general hospital was of great help in 38.8% and the rest of training was not much helpful as the training was inadequate due to lack of trainer or indifference of the trainer. For more effective training of the GPs, the training program of the NIH should be modified to be more realistic and utilize competent field workers as the instructors. It may be more effective if the training is carried out at several local centers. Ideal length of the clinical training for the GPs is 4 months. A pocketbook should be developed that includes specific skills to master during the clinical training and require the trainer to confirm the achievement. The Ministry of Health and Social Affairs should provide the training hospitals with a training guideline and evaluate the training activities and make sure that the training hospital has specialist for each of the 4 major clinical departments. The Ministry of Health and Social Affairs should provide the GPs with a continuing education to assist the problem solving in the field and motivate them to actively carry out the health program. A province may be divided into several regions and a supervisory committee may be organized with specialists in each region. The committee may hold a meeting for the GPs periodically and respond to the specific questions of the GPs by mail.

대구시내(大邱市內) 의과대학생(醫科大學生)들의 B형(型)바이러스성(性) 간염감염율(肝炎感染率)

박정한,윤태현,천병렬,송정흡,Park, Jung-Han,Youn, Tae-Hyun,Chun, Byung-Yeol,Song, Jung-Hup 대한예방의학회 1987 예방의학회지 Vol.20 No.1

의대생들의 B형바이러스성 간염의 감염율을 조사하고 그 예방대책을 강구하기 위하여 경북의대 1, 2, 3학년 가운데 B형 간염 백신 예방접종을 받은 학생을 제외한 자원자 385명을 대상으로 HBsAg, anti-HBs, anti-HBc를 RIA방법으로 측정하여 B형간염 감염율을 조사하고 설문지로 수혈력, 침술력, 수술력을 조사하고 HBsAg양성인 사람은 16개월 후에 재검사하여 변화양상을 조사하였다. HBsAg양성율은 6.8%이었으며 연령에 대한 보정을 했을 때 남자가 7.2%로 여자의 4.9%보다 높았으며, anti-HBs양성율은 35.8% (남자 36.1%, 여자 37 9%), anti-HBc양성율은 45.5% (남자 46.5%, 여자 44.5%)이었다. 따라서 B형간염 감염율은 49.1%로서 역시 남자(50.3%)가 여자보다(46.5%) 높았다. 학년별 HBsAg양성율 및 HBV감염율의 차이는 연령구성의 차이에 기인된 것 이었으며 연령별 HBsAg양성율은 20세가 1.7%, 21세 6.6%, 22세 6.1%, 23세 12.2%, 24세 이상에서 6.4%로 23세에서 가장 높게 나타났다. HBV감염율은 20세에서 45.8%, 21세 41.5%, 22세 49.5%, 23세 55.4%, 24세이상에서 59.6%로 나타나 연령이 증가할수록 감염율은 증가하였다. 이와같은 연령별 차이는 통계적으로 유의한 것은 아니었으나 타 연구결과와 종합해 볼 때 연령별 차이가 있을 것으로 생각되므로 같은 연령의 다른 학교 및 다른 계층을 대상으로 조사해 보고 연령에 따른 차이가 생기는 이유를 규명한다면 이 연령층에서 B형간염의 주요전파 경로를 밝힐 수 있을 것으로 생각된다. HBsAg양성인 26명가운데 1명만이 B형간염을 않고 있는 환자로 밝혀졌고 이들은 16개월 후에 재경사한 결과 검사에 응한 24명 중 22명이 계속 HBsAg양성이고 2명은 음성으로 되고 anti-HBs가 양성으로 나타났다. 본 연구 결과로 보아 20세 이전에 약 반이 B형간염에 감염되었고 재학중에도 감염이 일어나고 있으므로 입학 즉시 감염여부를 확인하고 미감염자에 대해 예방접종을 실시하고 임상에 종사하기 시작할 때 추가접종하는 것이 이상적일 것으로 생각된다. To determine the hepatitis 8 virus infection rate of the medical school students and appropriate time for immunization with hepatitis B vaccine,355 students in the 1st, 2nd and 3rd grades of Medical School of Kyungpook National University who had not been vaccinated and volunteered to participate in this study were tested for HBsAg, anti-HBs and anti-HBc with radioimmunoassay method (Abbott Lab. kit). A questionnaire was administered to ask the history of transfusion, acupuncture and surgery. HBsAg positive students were retested 16 months after the initial test. Overall HBsAg positive rate was 6.8% and the age adjusted rate for male (7.2%) was higher than that for female (4.9%). Anti-HBs positive rate was 35.3% (36.1% for male, 37.9% for female) and anti-HBc positive rate was 45.5% (46.5% for male,44.7% for female). Overall hepatitis B virus (HBV) infection rate was 49.1% and the infection rate for male (50.3%) was slightly higher than that for female (46.5%). HBsAg positive rate and infection rate were increased as the grade increased but it was attributed to the age distribution of the students. HBaAg positive rate for 20 years old students was 1.7%; 21 years, 6.6%; 22 years, 6.1%; 23 years, 12.2%; and 24 years and older, 6.4%. HBV infection rate showed an increasing trend as age increased; 45.8% for 20 years,41.5% for 21 years, 49.5% for 22 years, 55.5% for 23 years and 59.6% for 24 years and older. The age differences in HBsAg positive rates and HBV infection rates did not reach the statistical significance level of 0.05. However, these findings and similar age differences in HBsAg positive rates and HBV infection rates observed in other study suggest that there is a significant age differences. Study of the same age group in other schools and different social classes is warranted to confirm the age difference. Clarification of the reason for such differences would provide a clue to identify the major route of HBV transmission in this age group. Among 26 HBsAg positive students in the initial test, only one student was active hepatitis patient. Out of 24 students who had follow-up test after 16 months 22 students were positive for HBaAg and two students became HBsAg negative and anti-HBs positive. It is obvious that nearly one-half of the medical school students were infected with HBV before 20 years of age and the HBV infection occurs in medical school. Thus, it is recommended to test all the students for HBV infection soon after the admission to the medical school and immunize all the susceptible students with hepatitis B vaccine and give booster as they start to practice at a hospital.

고혈압 환자의 연간 내원일수, 처방일수 그리고 진료비

Objectives : To evaluate the annual visit days, the annual prescription days and the medical costs of hypertensive patients. Methods : The medical insurance records of 40,267 incident patients with the diagnostic code of hypertension from September 1998 through August 1999 in Daegu city were reviewed. Results : The proportion of the most proper medical care pattern group (Group VIII) who visited for 6-15 days with 240 prescription days or more a year was only 6.2%. The proper care group (Group IX) who visited for more than 16 days with 240 prescription days or more a year was 9.3%. The overall proper care group (Group VIII+IX) was therefore 15.5%. The proportion of the insufficient care group (Group I, IV) in both the number of visiting days and prescription days was 57.4%. The mean prescription day of the most proper group (Group VIII) was 29 days; the mean annual medical expenses,453,587won; the mean annual amount paid by patients, 218,013won; and mean medical expenses per prescription day, 1,483won. The proportion of the overall proper care group (Group VIII+IX) was significantly higher in adults aged 50-59, those who were enrolled in industrial workers health insurance as well as government employees and private school teachers health insurance, and those who made a higher contribution per month (p<0.01). According to the type of medical facilities, the proportion of the most proper medical care pattern group was highest in the general hospitals (9.3%) but the overall proper care group was higher in the public health centers (22.1%) and private clinics (17.1%). Conclusions : The management system of hypertension should be reinforced urgently. Therefore, it is necessary to develop guidelines including the number of visiting days per year and prescription days per visit day, and make the system provide medical facilities to more properly care for hypertensive patients.

추적조사에 의한 농촌 여성의 출산력과 임신소모율

박정한,김신향,천병렬,김귀연,예민해,조성억,조재연,Park, Jung-Han,Kim, Sin-Hyang,Chun, Byung-Yeol,Kim, Gui-Yeon,Yeh, Min-Hae,Cho, Seong-Eok,Cho, Jae-Yeon 대한예방의학회 1988 Journal of Preventive Medicine and Public Health Vol.21 No.1

농촌 여성들의 출산력과 임신소모율을 조사하기 위해 군위군에 거주하는 15-49세의 여성 가운데 조사시작 당시 영구불임 수술을 하지 않은 유배우 가임여성을 대상으로 17명의 면 보건요원들이 1985년 4원 1일부터 1987년 3월 31일까지 2년간 추적 관찰하여 그들의 피임 실천율, 출산율 그리고 임신 소모율을 조사하였다. 총 관찰된 6,826 여성인년 가운데 피임을 실천한 기간은 3,522인년(51.6%), 임신, 유산 그리고 출산을 한 기간은 519인년(7.6%)이었으며 피임을 하지 않은 기간은 2,491인년(36.5%)이었다. 조사시작 당시에 영구불임 수술을 한 사람을 포함시켰을 경우에는 피임을 실천한 기간이 72.1%로 전국의 피임 실천율보다 오히려 높은 수준이었다. 그러나 30대 여성의 경우 2-3명의 자녀를 갖고서도 피임을 하지 않고 있는 사람이 약 28%나 되고, 피임을 하는 경우에도 월경 주기법이나 콘돔과 같은 실패율이 높은 피임법을 20대 여성보다 더 많이 쓰고 있었다. 관찰기간 동안 전체적으로는 100 여성인년당 14.3건의 임신이 일어났으며, 25-29세 여성 이 100 여성인년당 27.4건의 임신으로 가장 높은 임신율을 보였다. 전체임신 중 22.0%가 사산(0.9%), 자연유산(3.8%), 그리고 인공유산(17.3%)으로 소모되었다. 연령이 증가함에 따라 임신 소모율이 증가하여 30세 미만 부인의 임신 소모율은 15.8%인데 비해 30대 여성이 임신을 한 경우 37.5%가 인공유산을 하여 자연유산과 사산을 합한 임신 소모율이 43.5%나 되었다. 추적기간 동안에 인공유산으로 종결한 부인이 출생으로 종결한 부인에 비해 평균 자녀수와 자연유산 및 인공유산 경험회수가2배 이상으로 많아 유산을 경험한 사람이 유산을 반복하고 있었다. 출생으로 종결한 임부는 평균 4.2회의 산전 관리를 받았고 분만은 85%가 의료기관에서 일어났으며, 가정 분만은 15%로 전국의 농촌지역에 비해 높은 시설 분만율을 나타냈는데, 이것은 군위군이 일차 보건의료시범사업 지역이었기 때문으로 생각된다. 이와 같은 연구 결과로 보아 농촌 여성을 대상으로 한 가족계획 사업은 30대 여성을 대상으로 하여 경구 피임약이나 자궁내장치와 같이 피임 효과가 높은 피임법을 보급하는데 중점을 두어야 임신 소모율을 줄이고 여성건강을 증진시킬 수 있을 것으로 생각된다. To measure the fertility rate and pregnancy wastage of women in rural area, 3,780 married women under 50 years old who were not sterilized either woman or husband in Gunwee county were followed up for 2 years. Seventeen Myun health workers visited these women periodically to check the status of their family planning practice and menstruation. Pregnant women were interviwed for their past obstetric history and followed up to the time of delivery. Family planning was practiced in 51.6% of the 6,826 women-years observed during the period from April 1, 1985 to March 31, 1987. Pregnancy, abortion and delivery covered 7.6% of the observed women-years and family planning was not practiced in 36.5% of the women-years. When sterilized women at the beginning of the study were included, the family planning practice rate was 72.1% which was slightly higher than the national family planning practice rate. However, 28% of the women of 30-39 years old had not practiced family planning although they had 2-3 children and they used more such less effective methods as safe-period method and condom than the women of 20-29 years old. Overall pregnancy rate was 14.3 per 100 woman-years. Women of 25-29 years old had the highest pregnancy rate of 27.4 per ,100 woman-years. Pregnancy wastage including spontaneous and induced abortions and still births was 22.0% of all pregnancies and it increased with the age of women; 15.8% in women less than 30 years old and 43.7% in women of 30 years and over. Women who terminated the pregnancy with induced abortion had more pregnancies, more previous induced and spontaneous abortions and shorter pregnancy interval than those women who terminated with live birth. Pregnant women terminated with a live birth had received 4.2 prenatal cares on the average. Eighty-five percent of deliveries occurred at a medical facility and 15% at home which was substantially lower home delivery rate than the other rural area of Korea. This may be due to the effects of the demonstration project for the primary health care in 1970s in Gunwee county. These findings suggest that family planning service in rural area should be strengthened by promoting the use of more effective contraceptive method among women over 30 years of age.

Cohort Infant Mortality Rate of Gunwee and Hapchun Counties and an MCH Center in Taegu

1985년 4월 1일부터 1987년 3월 31일 사이에 경상북도 군위군에 거주하는 49세이하의 가임여성들과 1987년 3월 1일부터 1988년 2월 28일 사이에 경상남도 합천군에 거주하는 49세이하의 가임여성들 그리고 1985년 4월 1일부터 1987년 3월 31일 사이에 대구시 남구 모자보건센터에 분만을 위해 찾아온 모든 임산부들을 대상으로 이들에게서 태어난 출생아들을 두 군지역에서는 생후 1년간 그리고 모자보건센터에서 출생한 경우는 생후 27일간 추적하여 영아사망률과 신생아 사망률을 각각 조사하였다. 조사기간중에 군위군과 합천군에서 출생한 1,359명의 영아들 가운데 생후 1년 동안에 17명이 사망하여 농촌지역의 영아사망률은 출생아 1,000명당 12.5이었다. 총 영아사망중 신생아사망이 82.4% 그리고 신생아 후기 사망이 17.6%를 차지하였다. 대구시 남구 모자보건센터에 내원한 산모들에게 태어난 6,001명의 출생아들 가운데 4,834명(80.6%)만이 생후 27일까지 추적되었는데 이들 중 36명이 사망하여 신생아 사망률은 출생아 1,000명당 7,4명이었다. 추적된 산모와 추적 안된 산모의 특성 및 신생아 체중을 비교한 결과 현저한 차이를 나타내지 않았다. 신생아 후기 사망률의 비를 6 : 4로 가정했을 때 모자보건센터에서 출생한 영아의 영아사망률은 출생아 1,000명당 12.3명으로 추정되었다. 군위군과 합천군의 영아사망률과 대구시 남구 모자보건센터에서 관찰된 신생아사망률, 영아사망의 사망시기별 분포와 영아사망원인 그리고 저체중아출생률을 고려할 때 1985년부터 1988년 사이의 한국의 영아사망률은 출생아 1,000명당 12에서 15명일 것으로 추정되었다. We followed up all the infants born to the married women under 50 years of age residing in Gunwee county, Kyungpook Province, between 1 April 1985 and 31 March 1987, and those born to the married women under 50 years residing in Hapchun County, Kyungnam Province, between 1 March 1987 and 28 February 1988, to their first birthday. Likewise, we followed up the infants born to the women who visited the MCH Center of South District Health Center in Taegu City for delivery between 1 April 1985 and 31 March 1987 to the 27th day after birth and obtained the infant mortality rate and the neonatal mortality rate, respectively. There were 17 infant deaths among 1,359 live births in Gunwee and Hapchun Counties and the infant mortality rate was 12.5 per 1,000 live births. Out of 17 infant deaths, 82.4 percent were neontal death and 17.6 percent were postnonatal deaths. Out of the 6,001 live births born to the women visited the MCH Center, 4,834 infants (80.6%) were followed up to the 27th day after birth. Of these 4,834 infants, 36 infants died before the 28th day after birth and thus the neonatal mortality rate was 7.4 per 1,000 live births. Comparison of the maternal characteristics and the birth weight between infants who were followed up and those who were lost to follow-up showed no significant differences. Assuming that the neonatal and postneounatal mortality ratio had been 6:4, the infant mortality rate for the infants born at the MCH Center would have been 12.3 per 1,000 live births. Taking such findings into consideration as the infant mortality rate observed in Gunwee and Hapchun Counties, the neonatal mortality rate at the MCH Center, the causes of infant deaths, and the low birth weight incidence rate, a conservative estimate of infant mortality rate of Korea would be between 12 and 15 per 1,000 live births in $1985{\sim}1988$.

Objective : To elucidate risk factors for coronary heart diseases among Korean males. Methods : A nested case control study was conducted among a Korea Medical Insurance Cooperation(KMIC) cohort composed of 108,802 males. The eases included 246 male patients who were admitted to hospital due to coronary heart diseases from 1993 to 1997 (120-25 by ICD) and whose diagnosis was confirmed by the protocol by WHO MONICA Project(1994). The control group was composed of 483 patients selected by frequency matching considering age and resident area from an inpatient care group without coronary heart disease during the same period. For study cases and the controls, the results of a health check-up in 1990 and a questionnaire on life style in 1992 were received through the KMIC. Some additional information was collected by telephone interviews during October 1999. Results : Multiple logistic regression analysis showed that the odds ratio(OR) of coronary heart diseases among past smokers and current smokers as compared to non-smokers were 1.94(95% CI : 1.14-3.31) and 2.20(55% CI : 1.35-3.59), respectively. The OR among persons who drank 4 cups or more of caffeinated beverages such as coffee or tea daily as compared to persons who drank one cup for 2-3 days was 2.50(95% CI : 1.07-6.12). The OR among persons with high normal BP and stage 3 hypertension against normotension were 2.51 (95% CI : 1.44-4.37) and 5.08(95% CI : 2.38-10.84). The OR among persons whose blood cholesterol were 240 mg/dL or mere against lower than 200mg/dL was 2.24(95% CI : 1.43-3.49). Conclusion : Smoking, drinking of excessive caffeinated beverages, hypertension and high blood cholesterol were proven to be significant risk factors for coronary heart diseases among Korean males.
