Purpose: The incidence and prevalence of inflammatory bowel disease (IBD) are increasing along with an increasing number of patients with comorbid conditions like psychiatric and behavioral disorders, which are independent predictors of quality of life. Methods: Non-overlapping years (2003-2016) of National Inpatient Sample and Kids Inpatient Database were analyzed to include all IBD-related hospitalizations of patients less than 21 years of age. Patients were analyzed for a concomitant diagnosis of psychiatric/ behavioral disorders and were compared with IBD patients without psychiatric/behavioral disorder diagnoses for outcome variables: IBD severity, length of stay and inflation-adjusted hospitalization charges. Results: Total of 161,294 IBD-related hospitalizations were analyzed and the overall prevalence rate of any psychiatric and behavioral disorders was 15.7%. Prevalence rate increased from 11.3% (2003) to 20.6% (2016), p<0.001. Depression, substance use, and anxiety were the predominant psychiatric disorders. Regression analysis showed patients with severe IBD (odds ratio [OR], 1.57; confidence interval [CI], 1.47-1.67; p<0.001) and intermediate IBD (OR, 1.14; CI, 1.10-1.28, p<0.001) had increased risk of associated psychiatric and behavioral disorders than patients with a low severity IBD. Multivariate analysis showed that psychiatric and behavioral disorders had 1.17 (CI, 1.07-1.28; p<0.001) mean additional days of hospitalization and incurred additional $8473 (CI, 7,520-9,425; p<0.001) of mean hospitalization charges, independent of IBD severity. Conclusion: Prevalence of psychiatric and behavioral disorders in hospitalized pediatric IBD patients has been significantly increasing over the last two decades, and these disorders were independently associated with prolonged hospital stay, and higher total hospitalization charges.

Cancer can be a major cause of poverty. This may be due either to the costs of treating and managing the illness as well as its impact upon people's ability to work. This is a concern that particularly affects countries that lack comprehensive social health insurance systems and other types of social safety nets. The ACTION study is a longitudinal cohort study of 10,000 hospital patients with a first time diagnosis of cancer. It aims to assess the impact of cancer on the economic circumstances of patients and their households, patients' quality of life, costs of treatment and survival. Patients will be followed throughout the first year after their cancer diagnosis, with interviews conducted at baseline (after diagnosis), three and 12 months. A cross-section of public and private hospitals as well as cancer centers across eight member countries of the Association of Southeast Asian Nations (ASEAN) will invite patients to participate. The primary outcome is incidence of financial catastrophe following treatment for cancer, defined as out-of-pocket health care expenditure at 12 months exceeding 30% of household income. Secondary outcomes include illness induced poverty, quality of life, psychological distress, economic hardship, survival and disease status. The findings can raise awareness of the extent of the cancer problem in South East Asia and its breadth in terms of its implications for households and the communities in which cancer patients live, identify priorities for further research and catalyze political action to put in place effective cancer control policies.

This study suggests a model for continuing and comprehensive management of hypertension or Type 2 diabetes mellitus (T2DM) in Korea. Moreover, this paper computed the contribution cost of hypertension or T2DM management using the healthcare medical cost, which could have occurred from stroke, myocardial infarction (MI), and end-stage renal disease (ESRD) that were successfully prevented from the effective hypertension or T2DM management. Additionally, these costs were compared with the cost of implementing the hypertension or T2DM management model suggested in this study. This study used the medical fee summary of the health insurance claims submitted to National Health Insurance Corporation by medical facilities for services provided during the period from January 1st 1999 to December 31st 2006. The prevalence rate with treatment referred to cases in which patients submitted their medical claims at least once during the period, along with an accordant diagnosis. The incidence rate with treatment referred to cases in which patients who never submitted claims for the accordant disease during the five years from 1999 to 2003 submitted claims for the accordant disease in 2004 and 2005. The relative risk of the occurrence of stroke, MI and ESRD was 11.0, 13.6, and 30.3, respectively. The attributable risk of hypertension or T2DM for stroke was 0.730, and that for MI and ESRD were 0.773 and 0.888, respectively. Based on these, the contribution cost of hypertension or T2DM is estimated to be 986.3 billion Korean Won(KRW) for stroke patients, 330.5 billion KRW for MI patients, and 561.7 billion KRW for ESRD patients as in 2005. Hence, the total contribution cost of hypertension or T2DM to stroke, MI, and ESRD is 1.878 trillion KRW. The estimate for operational costs included an annual expenditure of 50,000 KRW per each recipient and an annual subsidy of 0.22 million KRW per person for the 1.6 million low.income individuals with hypertension or T2DM to cover their out.of.pocket medical expenses. Under this assumption, it took approximately 0.6 trillion KRW to manage 5 million high.risk patients in the low. and mid.income range, coverings up to 50% of costs. In conclusion, considering the potential benefits of preventing stroke, MI, and ESRD, the costs seems to be reasonable.

High price equipment is one of the major factors that increases national health expenditure in developed countries. Computerized Tomography(CT), one of the important high price equipment, has been concerns of health service researchers and policy makers in many countries. In Korea, CT, first introduced in 1984, have spreaded nationwide with rapid speed. Though the Committee for Approving Import of High Price Medical Equipment, founded in 1981, tried to regulate the introduction of high price medical equipment including CT, the effort resulted in failure. The exact situation of diffusion of the high price equipment, however, was not yet investigated. We aimed at the description of the diffusion of CT in Korea and analysis of influencing factors on hospitals for the adoption of CT. We mainly used the database of CT, made in 1996 by the National Federation of Medical Insurance for the purpose of insurance payment for CT. Also characteristics of hospitals were gathered from yearbooks published by the central and local governments and by the Korean Hospital Association. We calculated the cumulative number of the CT per one million population year by year. In turn, multiple linear logistic regression was done to find out the contributing factors for the adoption of CT by each hospital. In the logistic regression model, it is regarded as dependent factor whether a hospital retained CT or not in 1988 and 1993. The major categories of the independent factors were hospital characteristics, environmental factors and competitive conditions of hospitals at the period of the adoption. The results are as follows: Number of CT scanners per one million persons in Korea marked more higher level compared with those of most OECD countries. Major influencing factors on the adoption of CT scanners were hospital characteristics, such as hospital referral level, and competitive condition of hospitals, such as number of CT scanners per 10,000 persons in each district where the hospital was located. In Korea, CT diffused with rather rapid speed, comparable with those of the United States and Japan. The major factors contributing on the adoption of CT for hospitals were competitive condition and hospital characteristics rather than regional health care need for CT. In conclusion, a kind of regulating mechanism would be necessary for the prevention of the indiscreet adoption and inefficient use of high price equipment including CT.

In order to find out health problems among inhabitants in slum areas in Kwanak-Ku, Seoul, a series of health survey was conducted upon 510 households by interview from March to December, 1976. The results obtained were as follows: 1. Employments of householders were unstable; Out of 508 householders, 164(32.3%) were unemployed and 184 (36.2%) were daily or temporary employees. 2. Average number of households per house was 2.0 and average area of residential room per person was $4.0m^2$. 3. 476(93.3%) out of 510 households were supplied with tap water and rest of them made use of ground water as a source of drinking water. 4. Only 279(18.3%) out of 1527 live births were delivered at medical facilities, 496(32.7%) were at home attended by doctors or midwives and 358(25.1%) took prenatal care. The above findings were worse in urban slum area than in other urban area of relatively high economic level, but were better than in rural area of less medical facilities. 5. Initiation of treatment were delayed until their illnesses were advanced in most of the households, 472(92.5%) out 510. In the early stage of the illness, 131(25.6%) of the house-holds sought physicians in their clinics or general hospitals and 250 (40.9%) visited chemists, to toy drugs at first hand. Frequency of visits to physician increased to 52.8% as the disease aggravated in later stages. 6. Cost of medical expenditure per household amounted to 815 won, and was paid to, in the order of chemists, physicians, chinese herb stores, chinese herb doctors. 7. Concerning the health knowledge of the inhabitants, 273(53.9%) out of 506 respondents were aware of the infectivity of pulmonary tuberculosis, and 68(13.4%) of them checked regularly their chest findings by X-ray at least once every two years. 8. As for the family planning, although 448(87.3%) out of 510 respondents were in favor of it, 215 (41.8%) of them were actually practicing contraception. 9. About 40.6% (125 respondents) of them obtained information and knowledge concerning contraception through personal contact with family planning workers. 10. Nutritional status of housewives was generally poor: 49(38.3%) out of 128 housewives were found to be anemic and average serum protein level was $7.5{\pm}0.82g/dl$.

민간보험은 공적보험과 보완적인 관계를 형성함에도 불구하고 우리나라의 민간보험은 소득계층에 따른 접근성 차이로 인한 사회적 불평등, 도덕적 해이로 인한 공적보험 재정악화 등의 우려를 낳고 있다. 그러나 이에 관한 실증적 분석은 그간 이루어지지 못하여 정책적인 방향을 정립하는 데 장애가 되어 왔다. 본 연구는 건강보험공단, 심사평가원, 민간보험사, 행정자치부 주민등록세대정보 등의 관련 정보를 종합하여 이에 대한 실증분석을 시도했다. 그 결과, 우리나라의 민간보험 가입률은 전 국민의 64%에 달하고 있으며, 고소득층과 저소득층 간에 민간보험 가입률의 차이가 나타나지 않았다. 이는 공적보험의 보장성이 미흡한 상황에서 저소득층 역시 갑작스런 의료지출에 대비하고 있으며, 민간보험이 의료접근성의 계층화를 초래하지 않고 있다는 것을 시사한다. 또한 민간보험 가입자는 평균적으로 미가입자에 비해 의료이용량이 높지 않았으며, Two-Part Model을 통해 다양한 변수를 통제했을 경우에도 동일한 결과가 나타났다. 연령대에 따른 차이로 미루어 이러한 결과는 노동시장과 연관된 한시적인 성격일 것으로 추측되나, 현재로서는 민간보험 가입에 따른 도덕적 해이가 강하게 나타나고 있다는 근거는 발견되지 않았다.

본 연구는 자기공명영상(MRI)의 건강보험 적용 전 후 이용량 동향과 이용량에 영향을 미치는 요인을 알아보기 위해 실시하였다. 연구재료는 2004년 1월부터 2013년 12월까지 대전광역시 소재 종합병원(2차 의료기관)의 MRI 실시자료(처방 정보 전달 시스템), 보험심사자료, 건강보험요양급여자료(건강보험심사평가원)를 이용하였고, 분석대상은 2004년(건강보험 적용 전) 3,754명, 2005년 - 2013년(건강보험 적용 후) 4,107명-8,630명 이었다. 분석은 이용자 특성(성별, 연령, 검사부위, 보험유형)과 공급자 특성(진료과, 진료형태)의 MRI 건강보험 적용 전 후 이용량 비교를 $X^2$ 으로 하였고, MRI 이용량에 영향을 미치는 요인분석을 위계적 다중회귀분석으로 실시하였다. 연구결과 건강보험 적용 초기에 한시적으로 이용량이 감소하지만 이후 꾸준히 증가하였다. 특히 여성의 검사 율, Head & Neck의 검사 율, 일반수가적용 환자의 검사 율, 내과의 검사율, 입원환자의 검사 율이 건강보험 적용 전에 비해 증가하였다. 그리고 MRI의 건강보험 적용은 검사 율 증가에 영향을 미치는 것으로 분석되었다(P<.0001). MRI 검사 율이 증가하는 만큼 국민의료비 감소를 위해 건강보험 적용 확대가 적극적으로 이루어져야 할 것이다.

Recently interests on raw-food diets are rapidly increasing in relation to chronic diseases prevention in Korea, but studies on raw-food diets have been hardly performed by nutritionists. This study was performed to investigate the effects of low-calorie diets using a raw-food formula in the form of freeze-dried powder on obesity and its complications in the obese women (body mass index (BMI) $\geq$ 25kg/㎡) for eight weeks. Forty premenopausal women (mean BMI 28.04kg/㎡, mean age 28.33years old) participated in this diet intervention, and were controlled by eating 1 regular meal, 1-2 snacks and 2 raw-food formula (140kcal/pack) meals a day within the 1500-1300kcal ranges. Anthropo-mentric measurements, body compositions, physical exercise, and obesity-related risk factors were assessed before (the initial), during (the 4th week) and after (the 8th week) the study. All the data was analyzed by paired t-test, repeated measures ANOVA, and nonparametric rank test at p<0.05 level. Obesity was significantly increased during this study, and it was decreased in weight (-4.59%, p<0.000), BMI (-4.56%, p<0.000), body fat percent (-6.18%, p<0.000), fat mass (-10.19%, p<0.000), waist and hip circumferences(-5.69%, p<0.000 and -2.55%, p<0.000) and WHR (-3.24%, p<0.000). Energy expenditure of physical exercise was increased as much as 70kca1/day during the study (p=0.000), but it did not have any correlations with weight loss and changes of body compositions. Biochemical measurements including blood triglyceride(p <0.006) and leptin(p<0.000) levels were significantly decreased, LDL cholesterol level was increased(p<0.05), but all the blood lipid levels were in the normal ranges. Fatty liver echogenicity and menstrual irregularity were improved after the diet intervention(p<0.000 and p<0.034). In conclusion, this B-week low-calorie diet intervention using raw-food formula was effective for obese premenopausal women in reducing obesity and its risk factors so as not to proceed towards comorbidities. However, the variation of blood lipid levels should be observed for a longer Period.

저출산과 고령화 등의 인구구조의 변화는 미래 건강보험 재정의 안전성을 위협하고 있다. 이에 본 논문에서는 2002년부터 2013년까지 국민건강보험 표본코호트 DB를 이용하여 유병율 및 진료비에 대한 통계적 모형을 추정하고 인구구조와 경제상황의 변화에 대한 다양한 미래 가정들을 반영하여 건강보험 재정의 연도별 수입과 지출을 2060년까지 추계하였다. 지출 추계에는 건강보험공단 표본 코호트 DB를 이용하여 유병율 및 진료비를 추계하였다. 유병율 모형은 VECM-LC모형을 그리고 1인당 공단 부담 진료비에 대한 추계는 이중지수평활법에 근거 하였다. 두 모형 모두를 의료기관별, 질병별, 성별, 연령별로 적합하고 경제상황의 변화에 대한 국회와 정부의 여러 가정들을 반영하여 최종 추계치를 산출하였다. 수입 추계는 고령화 속도에 대한 두 개의 다른 가정에 근거한 두 개의 미래 인구구조를 반영한 두 개의 피부양률 가정에 근거하고, 지출 추계에서와 마찬가지로 경제 상황의 변화에 대한 여러 가지 가정을 반영하여 최종 추계치를 산출하였다. 그 결과 건강보험 재정적자는 2015년 불변가격으로 2030년에는 2030조 원, 2060년에는 4070조 원이 될 것으로 추계되었다.
