Objectives: We wanted to determine the distribution of the clustering of the metabolic risk factors and we wanted to evaluate the related factors in young schoolchildren. Methods: A cross-sectional study of metabolic syndrome was conducted in an elementary school in Seoul, Korea. We evaluated fasting glucose, triglyceride, HDL cholesterol, blood pressures and the body mass index, and we used parent-reported questionnaires to assess the potential risk factors in 261 children (136 boys, 125 girls). We defined the metabolic risk factors as obesity or at risk for obesity ($\geqq$ 85th percentile for age and gender), a systolic or diastolic blood pressure at $\geqq90th$ percentile for age and gender, fasting glucose at $\geqq110mg/dl$, triglyceride at $\geqq110mg/dl$ and HDL cholesterol at $\leqq40mg/dl$. Results: There were 15.7% of the subjects who showed clustering of two or more metabolic risk factors, 2.3% of the subjects who showed clustering for three or more risk factors, and 0.8% of the subjects who showed clustering for four or more risk factors. A multivariate analysis revealed that a father smoking more than 20 cigarettes per day, a mother with a body mass index of = $25kg/m^2$, and the child eating precooked or frozen food more than once per day were associated with clustering of two or more components, with the odds ratios of 3.61 (95% CI=1.24-10.48), 5.50 (95% CI=1.39-21.73) and 8.04 (95% CI=1.67-38.81), respectively. Conclusions: This study shows that clustering of the metabolic risk factors is present in young schoolchildren in Korea, with the clustering being associated with parental smoking and obesity as well as the child's eating behavior. These results suggest that evaluation of metabolic risk factors and intervention for lifestyle factors may be needed in both young Korean children and their parents.

Objectives : We wanted to evaluate the medical underutilization for benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) among Korean elderly men and we wanted to determine their associated factors. Methods : This study was conducted on 239 men with LUTS and 116 men with BPH who were compatible with the diagnostic criteria from a total of 641 participants. These participants were over 50 years old and they were randomly chosen in a community-based study for estimating the prevalence of BPH. Using a self-reported questionnaire, we surveyed the sociodemographics, health status, quality of life, lower urinary tract symptoms, medical utilization and reasons for not seeking treatment. Results : Only 27.6% of the men with LUTS and 31.0% of the men with BPH reported having visited a doctor for urinary symptoms. The reasons for not visiting a doctor were, in order of responses from the group with LUTS: 'considered the symptoms as a part of the normal ageing process', 'not enough time to visit a doctor', 'financial difficulty' and 'the symptoms were not severe or bothersome'. Regarding BPH, the responses were the same as those of the group with LUTS however, 'financial difficulty' placed second. Among the men with experience of visiting a doctor for urinary symptoms, 33.3% of those with LUTS and 28.1% of those with BPH were not treated. The most common reason in both groups was 'the symptoms were not severe to be treated'. On a multiple logistic regression analysis, the larger size household (odds ratio (OR) 3.03, 95% confidence interval (CI)=1.40-6.54) and an unsatisfactory quality of life related with urinary symptoms (OR 2.98, 95% CI=1.23-7.21) were associated with medical utilization in the group of LUTS. For BPH, the current employment status was related with the medical utilization (OR 2.80, 95% CI=1.10-7.11), in addition to the larger size household (OR 3.24, 95% CI=1.14-9.21). Conclusions : Many men with urinary symptoms do not visit a doctor. This medical underutilization for people with LUTS and BPH may be associated with economic status in Korea.

Purpose: Since 2005, the Ministry of Health & Welfare has provided financial support to promote palliative care for terminal cancer patients. We analyzed how palliative care facilities used the funding between 2006 and 2010. Methods: Frequency analysis was conducted by the item of expenditure based on fiscal reports of the palliative care facilities. Linear regression analysis was performed to examine a trend over time. Kruskal-Wallis test and Wilcoxon rank-sum test were used to compare expenditure items, the number of provision of financial support and type of palliative care units. Results: About a half of the fund was spent to pay care givers salary, improve facilities and purchase equipment regardless of the year, the number of financial support provided or facility type. By year, the operation cost for palliative care program and the education cost for health care workers have significantly increased in linear regression analysis (P<0.01). However, the amount of financial support for the low income group has decreased over years (P=0.024). This trend was affected by evaluation criteria and weight. Conclusion: The government aid for palliative care units has been used to improve facilities and equipment. Moreover, desirable changes were noted such as a higher portion of expenses for program operation and care giver training to enhance the quality of care. However, the evaluation criteria need to be adjusted to prevent any further decrease in the support provided to the low income group. 목적: 본 연구는 완화의료 활성화 및 서비스 질 향상이라는 정책적 목표를 위하여 2005년부터 완화의료 전문기관에 지원된 운영비가 구체적으로 어떻게 사용되고 있는지 연도별, 지원 횟수별 그리고 종별로 현황을 파악하고, 지원사업의 효과성에 대해 평가하고자 하였다. 방법: 지원 대상 기관이 제출한 사업비 정산 보고서를 토대로 운영비의 비목별 사용 비율을 빈도분석 하였다. 연도별 추세를 파악하기 위해 선형회귀분석을 실시하였고, 지원받은 횟수별, 기관 종별에 따른 완화의료 전문 기관 운영비의 비목별 사용액에 차이가 있는지 알아보기 위해 추리통계방법인 Kruskal-Wallis Test와 Wilcoxon Rank-Sum Test를 이용하였다. 결과: 연도별 분석에서, 프로그램 운영비와 교육 훈련비 및 홍보비에 대한 지출 비율은 지속적으로 증가한 것으로 나타났다(P<0.001). 그러나 저소득층 지원비는 감소하는 추세를 보였다(P=0.024). 연도별 지원받은 횟수별 의료기관 종별에 관계없이 운영비의 절반가량을 인건비, 시설비, 장비비 등의 하드웨어 마련에 사용하고 있었다. 결론: 정부의 완화의료 활성화 지원사업은 장비와 시설 개선 그리고 서비스 질 향상을 위한 활동에 지원금이 꾸준히 사용되고 있음을 알 수 있다. 또한 당해 사업의 평가 기준이 기관의 운영비 사용 흐름에 영향을 주는 것으로 보이는데, 이에 따라 환자 가족을 위한 프로그램 운영과 전문가 교육 훈련에 대한 지출 비율이 늘어나고 있어 서비스 질 향상 위한 바람직한 변화로 보인다. 다만, 평가 기준 조정을 통해 감소하고 있는 저소득층 지원 비율을 향상시킬 필요가 있다고 판단된다.

목적: 최근 과거에 비해 A형 간염 발생률이 감소하고 있으나, 예방접종 도입 이전에 출생한 청소년들은 A형 간염의 대량발생 위험성이 있다. 본 연구는 A형 간염 예방접종을 시행하지 않은 청소년과 그 부모를 대상으로 A형 간염 예방접종에 대한 지식과 건강신념을 조사하였다. 방법: 만 13-19세의 A형 간염 과거력이 없고 예방접종을 시행하지 않은 건강한 청소년들과 그들의 보호자들을 대상으로 건강신념모델에 근거한 구조화된 설문지를 통해 조사를 실시하였다. 설문조사는 대상자들의 일반적 특성과 A형 간염 및 A형 간염 예방접종에 대한 지식과 건강신념을 조사하였고, 건강신념은 민감성, 심각성, 유익성, 장애성의 4가지 항목으로 측정하였다. 결과: 총 314명(157쌍)의 청소년과 보호자들이 모집되었고, 청소년과 보호자의 평균 나이는 각각 $16.0{\pm}1.6$, $45.6{\pm}4.7$세였다. 대상자의 A형 간염 및 예방접종에 대한 지식점수는 청소년, 보호자 각각 18점 만점에 평균 $6.4{\pm}3.7$점, $7.3{\pm}3.4$점이었으며, A형 간염과 예방접종에 관한 건강신념 세부항목들의 평균점수는 청소년과 보호자 각각 다음과 같았다. 민감성 점수(점수범위: 2-10점)는 $5.6{\pm}1.6$점과 $5.9{\pm}1.7$점; 심각성 점수(점수범위: 5-25점)는 $16.3{\pm}4.1$점과 $18.3{\pm}3.6$점; 유익성 점수(점수범위: 5-25점)는 $19.7{\pm}3.3$점과 $20.6{\pm}2.1$점; 장애성 점수(점수범위: 17-85점)는 $41.3{\pm}8.9$점과 $39.0{\pm}9.1$점이었다. A형 간염 예방접종을 시행하지 않은 가장 주된 원인은 청소년과 보호자 모두 'A형 간염 예방접종을 해야한다는 것을 알지 못했다'를 가장 많이 선택하였다. 결론: 청소년층의 A형 간염 대유행의 위험을 낮추고 접종률을 높이는 방안으로서 보호자가 함께 참여하는 반복적인 학교 보건교육이 필요하며, A형 간염 예방접종의 국가필수예방접종 도입도 고려되어야 하겠다. Purpose: Although the overall incidence of hepatitis A in Korea has been decreasing recently, the adolescents born before the introduction of the hepatitis A vaccine remain to be highly vulnerable to outbreak. This study examines the unvaccinated adolescents' and their parents' knowledge and health beliefs toward hepatitis A vaccination. Methods: Healthy adolescents aged 13-19 years old who had no previous history of hepatitis A vaccine and hepatitis A infection, and their parents or legal guardians were the subjects of the study. The survey was conducted using a structured questionnaire based on the Health Belief Model, and examined the subjects' demographics, knowledge, and health beliefs (i.e., perceived susceptibility, severity, benefits, and barriers). Results: We included 157 adolescents and their parents/guardians (mean age: $16.0{\pm}1.6$ and $45.6{\pm}4.7$ years, respectively). The average knowledge item score for adolescents and parents was $6.4{\pm}3.7$ and $7.3{\pm}3.4$ (out of 18), respectively. Similarly, average Health Belief Model item scores were: susceptibility, $5.6{\pm}1.6$ and $5.9{\pm}1.7$ (range: 2-10); severity, $16.3{\pm}4.1$ and $18.3{\pm}3.6$ (range:5-25); benefits, $19.7{\pm}3.3$ and $20.6{\pm}2.1$ (range:5-25); and barriers, $41.3{\pm}8.9$ and $39.0{\pm}9.1$ (range:7-85). The major reason for not undergoing hepatitis A vaccination was lack of knowledge about its importance. Conclusions: Refresher health lectures about hepatitis A and the vaccine are needed by both the adolescents and their parents. Furthermore, the inclusion of hepatitis A vaccine in the national immunization program should be considered to reduce the risk of hepatitis A outbreak and to raise the vaccination coverage among the adolescents in Korea.

Objectives: Exposure assessment is a major challenge faced by studies that evaluate the association between pesticide exposure and adverse health outcomes. The objective of this study was to investigate the reliability of information that farmers self-report regarding their pesticide use. Methods: Twenty five items based upon existing questionnaires were designed to focus on pesticide exposure. In 2009, a selfadministrated survey was conducted on two occasions four weeks apart among 205 farmers residing in Gyeonggi and Gangwon provinces. For a reliability measure, we calculated the percentage agreement, the kappa statistics and the intraclass correlation coefficient (ICC) between the two reports according to the characteristics of the subjects. Results: Agreement for ever-never use of any pesticide was 96.4% (kappa 0.61). For both 'years used' and 'age at the first use' of overall pesticides, high agreement was obtained (ICC: 0.88 and, 0.78, respectively), whereas those of 'days used' and 'hours used' were relatively low (ICC: 0.42 and, 0.66, respectively). The kappa value for the use of personal protective equipment ranged from 0.46 to 0.59, and hygiene activities came out at 0.19 to 0.37. The agreement for individual pesticide use ranged widely and there was relatively low agreement due to the low response rates. The reliability scores did not significantly vary according to gender, age, the education level, the types of crop or the years of farming. Conclusions: Our results support that carefully designed, self-reported information on ever-never pesticide use among farmers is reliable. However, the reliability of data on individual pesticide exposure may be unstable due to low response rates and needs to be refined.

검사법 평가: 검사법 비교와 신뢰도 평가

공경애 이화여자대학교 의과학연구소 2017 EMJ (Ewha medical journal) Vol.40 No.1

The reliability of clinical measurements is critical to medical research and clinical practice. Newly proposed methods are assessed in terms of their reliability, which includes their repeatability, intra- and interobserver reproducibility. In general, new methods that provide repeatable and reproducible results are compared with established methods used clinically. This paper describes common statistical methods for assessing reliability and agreement between methods, including the intraclass correlation coefficient, coefficient of variation, Bland-Altman plot, limits of agreement, percent agreement, and the kappa statistic. These methods are more appropriate for estimating reliability than hypothesis testing or simple correlation methods. However, some methods of reliability, especially unscaled ones, do not clearly define the acceptable level of error in real size and unit. The Bland-Altman plot is more useful for method comparison studies as it assesses the relationship between the differences and the magnitude of paired measurements, bias (as mean difference), and degree of agreement (as limits of agreement) between two methods or conditions (e.g., observers). Caution should be used when handling heteroscedasticity of difference between two measurements, employing the means of repeated measurements by method in methods comparison studies, and comparing reliability between different studies. Additionally, independence in the measuring processes, the combined use of different forms of estimating, clear descriptions of the calculations used to produce indices, and clinical acceptability should be emphasized when assessing reliability and method comparison studies.
