A cross-sectional study was conducted in an effort to investigate the effect of air pollution on respiratory symptoms. Two groups of female aged more than 20 living in the unpolluted rural area of Taebul (n=159) and urban area of Taegu (n=140) were selected. The ATS-DLD-78 questionnaire was translated into Korean and administered with minor modification. The proportion of smoker was less than 1% in both area. Exposure to smoking and higher educational level were more frequent in Taegu. Age-adjusted prevalence rates of 'chronic cough', 'chronic sputum', 'wheezing', and 'dyspnea' were higher in Taegu than in Taebul. In particular, the prevalence rate of 'chronic sputum' in Taegu was found to be higher, which was statistically significant. Exposure to smoking and education level were not concerned with all respiratory symptom prevalence rates. In conclusion, this study Indicates that an urban factor is related to the rates of respiratory symptoms in Korea.

연폭로의 정도와 자각증상과의 관계를 알아보기 위하여 435명의 연폭로 남자 근로자와 212명의 일반 사무직 남자 근로자를 대상으로 연폭로 지표가 되는 혈중 연, 혈중 Zinc Protoporphyrin(ZPP), 요중 Delta-aminolevulinic acid(DALA), 혈색소, 혈구 용적 측정을 위한 혈액 시료 및 소변 시료를 채취하여 분석하였고, 연관련 자각증상 조사는 14개의 증상 조사 항목을(표 3 및 별첨 1) 피검자가 응답 하도록하여 상담 의사의 면접을 통한 확인을 거쳐 수집 하였다. 수집된 각 항목은 인체 조직계 증상군별로 1) 위장관계 증상 2) 신경과 근육 및 관절계 증상 3) 일반 체질적 증상 4) 정신과적 증상으로 구분하여 연폭로 지표 수준과 연폭로 작업 여부에 따른 자각증상 호소율을 비교 조사하여 얻은 결론은 다음과 같다. 1. 연폭로군에서 대조군보다 유의하게 높은 자각증상 호소율을 보인 증상군은 신경과 근육 및 관절계 증상으로 "손이나 발이 저리거나 쥐가 잘난다", "관절이 아프거나 쑤신다", "손가락, 손, 발 등에 힘이 없다", "근육통을 느낀다" 순 이었다. 2. 연폭로군과 대조군의 자각증상 호소율에 가장 큰 차이를 보인 증상 항목은 "손이나 발이 저리거나 쥐가 잘 난다"였으며, 전체 조사 대상에서 가장 높은 증상 호소율을 보인 증상 항목은 일반 체질적 자각 증상군의 "전보다 피곤감을 느낀다"였다. 3. 전체 조사 대상의 혈중 연과 혈중 ZPP 수준에 따른 연폭로량의 증가와 자각증상 호소율의 증가를 보인 증상 항목은 신경과 근육 및 관절계 증상군의 "손이나 발이 저리거나 쥐가 잘난다", "관절이 아프거나 쑤신다", "손가락. 손 발 등에 힘이 없다", "근육통을 느낀다"와 위장관계 증상군의 "아랫배가 아파서 고생한 적이 있다"였다. 4 연폭로군에서 혈중 연과 혈중 ZPP 수준에 따른 연폭로량의 증가와 자각증상 호소율의 증가를 보인 증상 항목은 신경과 근육 및 관절계 증상으로 혈중 연의 증가에 따라 증상 호소율이 증가하였다. 5. 연폭로군에서 39세 이하 와 40세 이상 연령군으로 나누어 비교시 39세 이하 군의 증상 호소율이 40세 이상 군보다 높게 나왔으며. 신경과 근육 및 관절계 증상이 39세이하 군에서 혈중 연의 증가와 함께, 40세 이상 군에서 혈중 ZPP의 증가와 함께 자각증상 호소율의 증가를 나타냈다. 6. 연폭로 지표에 따른 폭로수준과 증상 호소율과의 관계를 알아보기 위하여 대조군에 대한 폭로군, 연폭로군의 저농도 폭로군에 대한 고농도 폭로군의 교차비를 산출한 결과 신경과 근육 및 관절계 증상군의 "손이나 발이 저리거나 쥐가 잘난다", "관절이 아프거나 쑤신다", "손가락, 손, 발 등에 힘이 없다", "근육통을 느낀다"와 위장관계 증상군의 "아랫배가 아파서 고생한 적이 있다"가 연폭로량의 증가에 따른 교차비의 증가를 보여 양-반응의 관계를 추정할 수 있었다.

Objectives : To determine the prevalence of prostatitis symptoms in the general population by questionnaire survey and to measure the effect of prostatitis symptoms on quality of life(QOL). Materials & Methods : A cross sectional community-based epidemiologic study was performed on 2,034 men, living in the Seoul metropolitan area using stepwise random sampling. Out of 2,034 interviewees, 1,356 men who were older than 40 and provided sufficient information were selected for this study. The questionnaires were completed by well trained interviewers. Contents of the questionnaires included demographic data, the Prostatitis Symptom Index(PSI), the International Prostate Symptom Score(IPSS), a general health questionnaire section and a sexual health questionnaire section. The PSI was composed of a sum of the scores from three questions about dysuria, penile pain and perineal pain and it ranged 0 to 12. Incidence of prostatitis symptoms was defined by a score of 4 or more and the reference group was defined as consisting of those with a score of 3 or less. The rate of incidence of prostatitis symptoms was assessed according to age and the difference of QOL between the prostatitis symptoms group and the reference group. Results : The overall positive rate of prostatitis symptoms measured by the PSI, in men older than 40, living in the Seoul metropolitan area, was 4.5%(61/1,356), adjusted to 4.8% by the relative proportion of this age group in the general population of the Seoul metropolitan area as compared to Korea and the World. The proportion of the group with prostatitis symptoms assessed by the PSI did not increase with age although the proportion of participants with moderate to severe lower urinary tract symptoms (LUTS) did increase with age. The group with prostatitis symptoms suffered from a much greater incidence of LUTS compared to the reference group (p<0.05). The QOL scores of the IPSS, and the general health and sexual health status of the group with prostatitis symptoms, were worse than those of the reference group.(p<0.05). Conclusions : The positive rate of prostatitis symptoms in men older than 40, living in the Seoul metropolitan area, was 4.8% and it didn't increase with age. The general QOL of the group with prostatitis symptoms was much worse than that of the reference group.

Objectives: The purpose of this study was to evaluate the association between body mass index (BMI) and severe lower urinary tract symptoms (LUTS) in Korean males. Methods: This study was conducted on males aged ${\geq}50years$ who participated in the 2011 Korean Community Health Survey. LUTS severity was assessed using the Korean version of the International Prostate Symptom Score (IPSS) questionnaire, and was dichotomized as severe (IPSS >19) and non-severe ($IPSS{\leq}19$). BMI was divided into 6 categories: <18.5, 18.5-22.9, 23.0-24.9, 25.0-27.4, 27.5-29.9, and ${\geq}30.0kg/m^2$. To evaluate the relationship between BMI and LUTS, a survey-weighted multivariate Poisson regression analysis was performed to estimate prevalence rate ratios (PRRs). Age, smoking status, alcohol intake, physical activity, educational level, household income, and comorbidities were adjusted for in the multivariate model. Results: A U-shaped relationship was detected between BMI and severe LUTS. Compared with a BMI of $23.0-24.9kg/m^2$, the PRR for a BMI < $18.5kg/m^2$ was 1.65 (95% confidence interval [CI], 1.35 to 2.02), that for a BMI of $18.5-22.9kg/m^2$ was 1.25 (95% CI, 1.09 to 1.44), that for a BMI of $25.0-27.4kg/m^2$ was 1.20 (95% CI, 1.00 to 1.45), that for a BMI of $27.5-29.9kg/m^2$ was 1.11 (95% CI, 0.83 to 1.47), and that for a BMI ${\geq}30.0kg/m^2$ was 1.85 (95% CI, 1.18 to 2.88). Conclusions: This study showed that both high and low BMI were associated with severe LUTS.
