Purpose: Coronary artery abnormalities (CAA) are the most important complications of Kawasaki disease (KD). Iron deficiency anemia (IDA) is a prevalent micronutrient deficiency and its association with KD remains unknown. We hypothesized that presence of IDA could be a predictor of CAA. Methods: This retrospective study included 173 KD patients, divided into 2 groups according to absence (group 1) and presence (group 2) of CAA. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a logistic regression model to estimate the association between CAA and other indicators. Due to collinearity between indicators of IDA, each indicator was paired with anemia in 3 models. Results: Serum iron, iron saturation, and ferritin concentration, the 3 indicators of IDA, were significantly higher in group 1 than in group 2. Three sets of models including anemia with iron indicators produced the OR of CAA of 3.513, 3.171, and 2.256, respectively. The 3 indicators of IDA were negatively associated with CAA, by OR of 0.965, 0.914, and 0.944, respectively. The areas under the curve (AUCs) of ferritin concentration, iron saturation, serum iron, anemia, and Kobayashi score were 0.907 (95% CI, 0.851-0.963), 0.729 (95% CI, 0.648-0.810), 0.711 (95% CI, 0.629-0.793), 0.638 (95% CI, 0.545-0.731), and 0.563 (95% CI, 0.489-0.636), respectively. Conclusion: Indicators of IDA, especially ferritin, were highly associated with CAA; therefore, they were stronger predictors of CAA than Kobayashi scores. IDA indicators can be used to predict CAA development and to suggest requirements for early interventions.

Background: It is important to investigate patient satisfaction to improve the quality of healthcare. Among the many factors that affect patient satisfaction, perceived health status has been considered as one of the major factors. Therefore, we investigated patient satisfaction through patient experience in outpatient settings according to perceived health status. Methods: This cross-sectional study using questionnaires of patient experience and perceived health status from the Korean National Health and Nutrition Examination Survey 2015 included 4267 people aged over 19 years who met the inclusion criteria. Perceived health status was classified into three: good, fair, and poor. Questions about patient experience consisted of four items: doctor spending enough time with patients, doctor providing easy-to-understand explanation, doctor giving opportunity to ask questions or raise concerns, and doctor involving patient in decisions about care or treatment. Patient experience was classified into two: satisfied and non-satisfied. A multivariate regression model was used to analyze the data. Results: In the good perceived health status group, level of satisfaction was 79.2%, 88.5%, 83.3% and 87.2%, respectively for the four items targeting patient experience. In the poor group, level of satisfaction was 76%, 84.9%, 79.5%, and 83.1%, respectively for the four items. In multivariate logistic regression analyses, the odds ratios of good perceived health status group were 1.775 (1.347-2.338), 1.946 (1.356-2.793), 1.652 (1.218-2.240), and 1.665 (1.193-2.323) compared with the poor group. Conclusion: Perceived health status is associated with patient satisfaction. In particular, the better the perceived health status, the better the patient satisfaction through patient experience.

본 연구는 수송부문에서 오염물질 배출 비중이 큰 화물차의 통행량에 영향을 미치는 요인을 분석하기 위하여 다중회귀모형을 추정하였으며, 모형 추정 결과 지역별 인구수, 도시지역 면적, GDP, 업종별(농업, 임업 및 어업, 광업, 제조업, 도매 및 소매업) 사업체수 등이 주요 변수로 검토되었다. 이러한 변수는 화물차 특성(업종, 톤급)에 따라 상이하게 나타나므로 차량 운행제한 등 관련 정책 추진 시에는 지역별 화물차 특성에 따른 통행량을 충분히 고려해야 할 필요가 있다. 특히 물류터미널 등 화물차 통행량이 많은 물류거점이 위치하지 않은 지역에 대해서는 화물차 통행에 영향을 미치는 지역별 요인을 고려하여 차량 운행제한 대상 지역을 검토해야 할 필요가 있다. 특히 본 연구의 결과에서 제시된 바와 같이 화물차 통행량과 지역 내 인구수는 양의 상관관계를 가지기 때문에 인구밀집지역에서는 화물차를 포함한 차량운행제한 검토가 필요하다. 본 연구 결과의 신뢰도를 높이기 위해서는 실제 통행량 자료를 기반으로 다중회귀모형 외 다양한 모형 추정을 통하여 추정 결과에 대한 오차를 줄여야 할 필요가 있다.

Objectives: This study aimed to examine the effect of maternal adverse childhood experiences (ACEs) on the attention-deficit/hyperactivity disorder (ADHD) symptoms in the offspring and to examine the mediating role of antepartum health risk on the intergenerational transmission of maternal ACEs. Methods: The participants consisted of 461 mother-child dyads. Mothers completed the ACEs questionnaire and Diagnostic Predictive Scales. Multivariate logistic regression analysis was used to estimate the risk of ADHD symptoms in the offspring of mothers with ACEs and the mediating effect of antepartum health risks by path analysis. Results: In all, 35.4% (n=163) had at least one maternal ACE, and 11.1% (n=51) had three or more. Compared to the non-ADHD symptom group, the group of offspring with ADHD symptoms showed a significant association with maternal ACE score (p<0.001) and antepartum health risks (p<0.001). Multivariate analysis further showed a significant association between the sum of maternal ACEs [odds ratio (OR)=1.264, 95% confidence interval (CI)= 1.060-1.516, p=0.009], antepartum health risks (OR=1.236, 95% CI=1.036-1.475, p=0.019), and ADHD symptoms in the offspring. In the mediation model in which the mother's ACE score affected the offspring's ADHD symptoms, partial mediation through antepartum health risks was found to be significant (B=0.041, 95% CI=0.011-0.124). Conclusion: Maternal ACEs are significantly related to the incidence of ADHD symptoms in the offspring and antepartum health risks exert an indirect effect. These findings suggest that maternal ACEs have a negative impact on the offspring's brain development through intergenerational transmission, resulting in neurodevelopmental disorders such as ADHD.

유학생활은 학교에서 뿐만 아니라 경제, 사회적 관계, 문화 등 다양한 영역에서 이루어지기 때문에 각 영역별로 만족수준은 개인마다 상이하게 나타날 수 있다. 따라서 유학생활의 질적인 수준을 제고하기 위해서는 이를 고려하여 다차원적으로 접근할 필요가 있다. 이에 본 연구는 외국인 유학생의 유학생활만족도를 다차원적으로 접근하여 탐색하였다. 이를 분석하기 위해 잠재집단분석을 적용하여 하위집단을 식별하였으며, 집단분류에 영향요인을 검증하기 위해 다항로지스틱회귀모형을 적용하였다. 분석결과는 크게 2가지로 정리된다. 하나는 유학생활만족도가 상이한 하위집단이 식별되었다. 하위집단은 주거, 경제, 사회적 관계, 학업, 문화 등 5가지 영역별로 상이한 만족수준을 보였으며, 단일차원에서는 발견되지 않는 집단들을 식별해냈다. 두 번째는 집단분류에 영향을 미친 요인은 학업적 요인, 심리·정서적 요인, 환경적 요인이 복합적으로 작용하였다. 특히, 하위집단별로 예측요인은 상이하게 영향을 미치는 것으로 나타났다. 이상의 연구결과를 바탕으로 외국인 유학생의 유학생활만족수준을 제고하기 위한 실천적, 정책적 제언을 모색하고자 한다.

Objective: To analyze osteoporosis treatment patterns and teriparatide prescription-associated factors in Korea by using a national health insurance claims database. Methods: We utilized the Health Insurance Review & Assessment Service National Patients Sample claims database to identify patients (aged ≥50 years) with at least one osteoporosis claim (International Classification of Disease 10th revision code: M80, M81, M82) and at least one prescription for osteoporosis medication (antiresorptive agents: bisphosphonates, selective estrogen receptor modulators, denosumab, and calcitonin; bone-forming agent: teriparatide) in 2018. Demographic characteristics and healthcare utilization patterns were analyzed. Factors associated with teriparatide prescriptions were assessed using a multivariate logistic regression model. Results: Records showed that 44,815 patients were prescribed osteoporosis medications in 2018; the percentage of patients prescribed each treatment was as follows: 86.6% bisphosphonates, 13.9% selective estrogen receptor modulators, 3.1% calcitonin, 2.1% denosumab, and 0.7% teriparatide. A greater proportion of patients prescribed teriparatide were ≥75 years (53.4% vs. 33.8%) and had fractures (63.9% vs. 12.8%) compared to the same for antiresorptives (p<0.001). Patients prescribed teriparatide had higher Charlson comorbidity index values (1.2±1.3 vs. 0.9±1.2) and were more frequently hospitalized (0.8±1.3 vs. 0.1±0.5) than those prescribed antiresorptives (p<0.001). Elderly patients (≥75 years old; adjusted OR=1.66; 95% CI 1.16-2.38) and those with fractures (adjusted OR=6.23; 95% CI 4.76-8.14) were more likely to be prescribed teriparatide than antiresorptives. Conclusion: Patients prescribed teriparatide were older and more likely to have severe osteoporosis than those prescribed antiresorptives.

Purpose : This study examined the factors related to sexual intercourse among adolescents in South Korea. Methods : The study sample was comprised of 65,528 middle and high school students aged 12 to 18 years in 2016. For this study, using the data from the 12th Korea youth risk behavior web-based survey, a chi-squared test, and hierarchical logistic regression analysis we reconducted with the SPSS 22.0 program considering personal, family, school, and regional characteristics. Results : The proportion of adolescents who had sexual intercourse was 6.0 % of boys and 2.7 % of girls, and 6.3 % of high school students and 2.4 % of middle school students. The statistically significant related factors of sexual intercourse were gender, grade, attempted suicide, ever drinking, ever smoking, habitual or purposeful drug use, weekly allowance, and coed school in the final model 4. Adolescents with suicide attempts had 2.49 times more sexual intercourse than adolescents with no experience of suicide attempts. Compared to adolescents without alcohol, smoking, and habitual drug use, those who have experienced alcohol, smoking, habitual or purposeful drug use were 2.22 times, 3.76 times, and 3.39 times more likely to have had sexual intercourse, respectively. Adolescents with a weekly allowance of more than 100,000 won per week and adolescents in coed schools were 2.84 times and 1.40 times more likely to have had sexual intercourse, respectively. Conclusion : Multi-level interventions should be considered in school sexual education programs while considering the substantiality of sex education and the actual adolescents' needs. In addition, sexual health interventions in cyberspace for high-risk groups may be needed to consider the emotional and mental characteristics, given the factors related to sexual intercourse in adolescents.
