Purpose: This study investigated the validity of the Charlson comorbidity index (CCI) as a predictor of periodontal disease (PD) over a 12-year period. Methods: Nationwide representative samples of 149,785 adults aged ${\geq}60$ years with PD (International Classification of Disease, 10th revision [ICD-10], K052-K056) were derived from the National Health Insurance Service-Elderly Cohort during 2002-2013. The degree of comorbidity was measured using the CCI (grade 0-6), including 17 diseases weighted on the basis of their association with mortality, and data were analyzed using multivariate Cox proportional-hazards regression in order to investigate the associations of comorbid diseases (CDs) with PD. Results: The multivariate Cox regression analysis with adjustment for sociodemographic factors (sex, age, household income, insurance status, residence area, and health status) and CDs (acute myocardial infarction, congestive heart failure, peripheral vascular disease, cerebral vascular accident, dementia, pulmonary disease, connective tissue disorders, peptic ulcer, liver disease, diabetes, diabetes complications, paraplegia, renal disease, cancer, metastatic cancer, severe liver disease, and human immunodeficiency virus [HIV]) showed that the CCI in elderly comorbid participants was significantly and positively correlated with the presence of PD (grade 1: hazard ratio [HR], 1.11; P<0.001; grade ${\geq}2$: HR, 1.12, P<0.001). Conclusions: We demonstrated that a higher CCI was a significant predictor of greater risk for PD in the South Korean elderly population.

Objectives : This study aims to estimate the oral antihyperglycemic medications adherence among ambulatory care with adult type 2 diabetes patients and to identify factors affecting the medication adherence in Korea. Methods : This study used the Korean National Health Insurance Database. Study population was 40,082 patients who were 20 years of age or older and first diagnosed with type 2 diabetes (ICD-10: E11) in 2004. The patients were followed up for two years in order to measure adherence with oral antihyperglycemic medications. The level of medication adherence was measured by the medication possession ratio (MPR). Results : The average MPR in the study population was 49.5%. The appropriate adherence rate (MPR$\geq$80%) was 29.4% and showed variation according to the characteristics of individual patients. Multiple logistic regression analysis revealed that the odds of appropriate adherence increased with female (OR:1.21, CI:1.14-1.27), older age, increasing ambulatory care visits, health insurance (OR:1.53, CI:1.33-1.76), decreasing ambulatory care providers, using a specialized general hospital as their main attending medical institution (OR:10.08, CI:8.96-11.33), having co-morbidity, using polytherapy (OR:1.07, CI:1.01-1.13). Conclusions : The medications adherence for patient with type 2 diabetes is low in Korea, and shows variation according to the characteristics of patients. For proper management of diabetes, health care policy is expected to be enacted to improve medications adherence continuously. In particular, more intensive management is needed for patients with low medications adherence. Also, health care policy makers need to develop the program to induce health care utilization by a patient to be more concentrated with the same provider.

Breast cancer is the most common cancer among Malaysian women. Other than hospital-based results, there are no documented population-based survival rates of Malaysian women for breast cancers. This populationbased retrospective cohort study was therefore conducted. Data were obtained from Health Informatics Centre, Ministry of Health Malaysia, National Cancer Registry and National Registration Department for the period from $1^{st}$ January 2000 to $31^{st}$ December 2005. Cases were captured by ICD-10 and linked to death certificates to identify the status. Only complete data were analysed. Survival time was calculated from the estimated date of diagnosis to the date of death or date of loss to follow-up. Observed survival rates were estimated by Kaplan-Meier method using SPSS Statistical Software version 17. A total of 10,230 complete data sets were analysed. The mean age at diagnosis was 50.6 years old. The overall 5-year survival rate was 49% with median survival time of 68.1 months. Indian women had a higher survival rate of 54% compared to Chinese women (49%) and Malays (45%). The overall 5-year survival rate of breast cancer patient among Malaysian women was still low for the cohort of 2000 to 2005 as compared to survival rates in developed nations. Therefore, it is necessary to enhance the strategies for early detection and intervention.

Objectives: The purpose of this study was to assess the incidence of delivery and puerperium complications in South Korea and analyze the correlations between the patient's characteristics and delivery and complications before and after 10 years. Methods: This study used the data from an Korean National Hospital Discharge In-depth Injury Survey. Cases of which the principal diagnosis and second diagnoses were disease classification ICD code O00-O99(Pregnancy, childbirth and the puerperium) were defined as the study subjects, and the first study group was divided as the year of discharge from 2005 to 2007, and the second study group from 2015 to 2017. Results: The number of patients discharged whose principal diagnosis or second diagnoses was O00-O99 was 21,598(Weighted 423,306) from 2005 to 2007 and 19,028(Weighted 364,384) from 2015 to 2017, which decreased by 13.9% compared to 10 years ago. The average age of discharged patients increased by about 2 years and was statistically significant (p<.0001). Factors associating spontaneous delivery, caesarean section and puerperium complication were hospitalization route, bed size, maternal age, length of hospital stay, and the year of discharge. Conclusion: Based on the results of this study, health and education policies and economic support for medical care for high-risk pregnancy and delivery management would be necessary continuously. In addition, policies to strengthen the medical system for high-risk pregnancy management in non-metropolitan areas with high fertility rates would also be needed.

Purpose: The purpose of this study was to investigate physical activity as a risk factor for neck pain recurrence using the National Health Insurance Data Sharing Service that utilizes a nationwide cohort in South Korea. Methods: Medical records spanning a two-year period were extracted from the National Health Insurance database for 541,937 patients who sought healthcare services for neck pain (ICD 10 codes: M54.2) in 2020 and completed the national health examination survey. Selected variables for analysis included age, gender, health insurance premium decile, regional health vulnerability index, body mass index (BMI), acuity, blood pressure, and types of physical activity. A mixed-effect multivariate logistic regression analysis was conducted to examine the recurrence rate of neck pain and identify risk factors for neck pain recurrence. Results: Among the participants, 124,433 patients (23.0%) experienced a recurrence of neck pain within two years, with higher recurrence rates observed among older individuals and females. Regression analysis revealed that the risk of neck pain recurrence increased with age (OR=1.51), being female (OR= 1.10), being a medical aid recipient (OR=1.51), and having anaerobic (OR=1.04) or vigorous physical activities (OR=1.06). By contrast, an increased health insurance premium decile (OR=0.96) and having moderate physical activity (OR=0.97) were associated with a decreased risk of neck pain recurrence. Conclusion: This study highlights the importance of moderate physical activity as an effective strategy for reducing the recurrence of nonspecific neck pain, underscoring the necessity for personalized physical activity programs for patients.

목 적 : 최근 수면장애에 대한 3가지 진단 분류 체계가 발달하였다. 즉 국제 수면장애 분류(the International Classification of Sleep Disorder, ICSD), 정신장애의 진단 및 통계 편람 제 4 판(the Diagnostic and Statistical Manual, 4th edition, DSM-IV) 그리고 국제 질병 분류 제 10 판(the International Classification of Diseases, 10th edition, ICD-10)이다. 국내에는 이들 진단 체계간의 비교에 대한 자료가 거의 없다. 본 저자들은 수면 문제로 정신과에 의뢰된 환자를 DSM-IV와 ICSD에 따라 진단하고 이를 비교하여 그 차이를 비교하고자 하였다. 방 법 : 고려대학부속 안암병원에 입원 환자 중 수면장애로 정신과에 의뢰된 284명의 환자를 대상으로 ICSD를 숙수면장애에 대한 ICSD와 DSM-IV 진단 비교 44지하지 않은 정신과 전공의와 ICSD를 숙지한 정신과 전공의가 비구조화된 면담을 시행하고, DSM-IV와 ICSD의 진단 기준에 따라 임상적 진단을 하여 그 차이를 비교하였다. 결 과 : DSM-IV 진단 분류에는 "기타 정신장애 관련 불면증"(전체의 61.1%)과 "일반적인 의학적 상태로 인한 섬망"(26.8%)이 빈도가 가장 높았다. ICSD에서는 "신경과적 장애가 동반된 수면장애" (38.4%)와 "정신과적 장애가 동반된 수면장애" (33.1%)의 빈도가 가장 높았다. DSM-IV와 ICSD의 비교에서, DSM-IV에서 신체적 질환이나 정신과적 질환과 무관한 수면장애로 진단된 환자군은 대부분 ICSD와 일치하였고, 이들 중 DSM-IV의 "일차적 불면증"은 ICSD의 "정신생리적 불면증"과 "부적수면위생"으로 구분되었다. DSM-IV에서 신체적 질환이나 정신과적 질환에 의한 수면장애를 가진 269명 중 62명(23%)이 ICSD와 불일치하였고 이들 중 대부분이 ICSD에서 신체적 질환이나 정신과적 질환과 무관한 수면장애인 "부적수면위생", "환경성 수면장애", "적응성 수면장애" 그리고 "수면결핍장애" 등이었다. 결 론 : 본 연구에서 DSM-IV와 ICSD의 진단 체계가 많은 부분 일치하였으나, 간과할 수 없는 차이를 가지고 있음을 확인하였다. 이 차이는 수면장애에 대한 임상의의 태도를 반영한다. 즉, 수면장애에 대한 개념화와 원인에 대한 임상의의 이해 정도에 따라, 수면장애를 진단하지 못하거나 적절한 치료를 할 수 없다. 따라서 본 연구에서 나타난 DSM-IV와 ICSD에 대한 임상의의 이해 정도는 중요하다고 할 수 있다.

Background: Cancer incidence rates are increasing particularly in developing countries. It is crucial for policy makers to know basic cancer epidemiology in each region to design comprehensive prevention plans. There have hitherto been no population-based data available for cancer in Khuzestan province. The present report is a first from the regional population-based cancer registry for the period of 2002-2009. Materials and Methods: Data were collected retrospectively reviewing all new cancer patients whom were registered in Khuzestan province cancer registry during an 8-year period (2002-2009). All cases were coded based on the ICD-O-3 coding system and collected data were computerized using SPSS (Chicago, IL) software, version 11.5. The age standardized incidence rates (ASRs) per 100,000 person-year for all cancers were computed using the indirect method of standardization to the world population. Results: During the 8-year study period, 16,801 new cancer cases were registered. Based on the computed ASRs, the five most frequent malignancies in females were breast (26.4 per 100,000), skin (13.6), colorectal (5.72), stomach (4.31) and bladder(4.07) and in males, the five most frequent were skin (16.0 per 100,000), bladder (10.7),prostate (7.64), stomach (7.17), and colorectal (6.32).The ASR for all malignancies in women was 92.5 per 100,000, and that for men was 87.4. Conclusions: The observed patterns from the analysis of Khuzestan cancer registry data will lead to better understanding of the epidemiology of various malignancies in this part ofthe country and consequently provide a useful guide for authorities to make efficacious decisions and policies about a cancer control program for south-west Iran.

Objective: To analyze the prescription patterns for the treatment of ulcerative colitis (UC) and to investigate factors co-occurring with systemic corticosteroid use. Methods: We used patient-level data from Korean National Health Insurance claims database to identify patients diagnosed with UC (ICD-10 code : K51) and their medications prescribed for UC between January 1 and Decemeber 31, 2017. We found that medications for UC treatment were 5-aminosalicylic acid (5-ASA), immunomodulators, biologics, and corticosteroids. We presented the prescription pattern according to the sex, age group, type of health insurance, site of UC, type of medical institution, and concomitant medication. To evaluate factors associated with prescription of systemic corticosteroids for UC, we used a multivariate logistic regression model to estimate adjusted odds ratios (aORs) and their 95% confidence intervals (CIs). Results: Of 1,469 UC patients, 74.5% used 5-ASA and 15.2% used systemic corticosteroids. 5-ASA constituted 77.5% of all prescriptions and systemic corticosteroids accounted for 13.1%. The most widely used therapy was 5-ASA monotherapy (54.8%), followed by a double therapy with 5-ASA and immunomodulators (8.2%) or 5-ASA and systemic corticosteroids (7.2%). Systemic corticosteroids were more likely to be prescribed with immunomodulators (aOR=1.88, 95% CI=1.54-2.28) and biologics (aOR=2.82, 95% CI=2.28-3.50) than without them. Conclusions: We found that 15.2% of UC patients were prescribed with a systemic corticosteroid, which is less than reported previously. Systemic corticosteroids were more likely to be prescribed with immunomodulators and biologics.

Objectives: The purpose of this study is to identify predictors of clinical efficacy of oriental medical treatment for patients with panic disorder. Methods: We analyzed medical records of 41 patients who were diagnosed with panic disorder through DSM-IV or ICD-10 by 2 oriental medical neuro-psychiatrists. We performed frequency analysis of demographic characteristics in patients with panic disorder, and assessed the correlation between the psychological scales by Pearson correlation. Repeated measures ANOVA were used to compare the psychological scales during the treatment; and Single regression analysis was used to analyze the factors that have correlation to improvement of panic disorder by oriental medical treatment. Psychological scales used in the study were STAI-X-1/2, STAXI-S/T, BDI2, BAI, BSQ, PAS, ASI, LOT-R, SWLS, LSES and LSMS. Results: Patients' demographic characteristics indicated that there were twice more female than male patients; furthermore, there was a high ratio of patients in their 20s and 30s, with the highest percentage of onset-age in the 20s and average duration of panic disorder from 1~5 years. More than half of the total patient cohort comprised of those who had panic disorder with agoraphobia and major depressive disorder; in addition, major accompanied symptoms were dyspepsia, chest discomfort and headache. After treatment, most scores of psychological scales were significantly reduced, and correlation between the psychological scales was significant. Furthermore, we identified some factors that were significantly correlated to improvement of panic disorder by oriental medical treatment. Conclusions: In conclusion, treatment of panic disorder with oriental medicine was clinically efficient and improved the quality of life.
