ABSTRACT
OBJECTIVE: The aim of our study was to define the prevalence, demographic data, selection of the medical services and disability of the patients with self-reported arthritis which were based on the data of National Health and Nutrition Survey (NHNS) conducted by Korea Institute for Health and Social Affairs (KIHASA) and Ministry of Health and Welfare in 1998. MEHTODS: By a stratified multistage probability sampling method, 200 sample districts which consisted of total 13,523 households were selected all over the country. The investigation started with a basic household survey which was completed in 12,189 households with exclusion of non-kinship family. The Health Interview Survey was subdivided to 5 parts including the basic household survey (n=39,060), the diseases survey (n=26,448), and the disability survey (n=694). RESULTS: An estimated 8.0% of Koreans had some form of self-reported arthritis in 1998 and this proportion was higher than that of other chronic medical conditions such as peptic ulcer disease, hypertension, and diabetes mellitus (DM) -7.0%, 4.5%, and 2.2%, respectively. Arthritis was more prevalent among people with female, increasing age, lower income (less than 500 thousand \ per month), lower educational attainment (less than 9 years), and lower standard of living. Especially, arthritis ranked first in prevalence as the cause of the chronic disease in the population aged over 45 years, with the prevalence rate of 22.6%. People with arthritis were more likely to report functional limitations such as activities of daily living (ADL) and instrumental activities of daily living (IADL) (5.4%), compared with people who had other musculoskeletal diseases, such as low back pain (3.8%), and herniated intervertebral disc (2.8%). The loss of productivity from arthritis was estimated to reach 0.25% of gross domestic product (GDP) amounts to won 1,133 billion per year which was remarkably higher than that of cardiovascular diseases or cancers. CONCLUSION: Arthritis has a major impact on the health profile of our population. High burden of arthritis in our society should be considered as an important factor in planning health care services and setting research priorities.

The purpose of this study was to investigate the epidemiological characteristics of hepatitis B virus (HBV) infection in Korea based on the 1998 National Health and Nutrition Survey. Study subjects consisted of 9,771 aged 10 yr or over, who were selected from across Korea using a stratified multistage probability sampling design. The prevalence of hepatitis B surface antigen (HBsAg) was compared by age, sex, residency, household income, education, family history, family size, and frequency of eating out. The prevalence of HBsAg was 5.1% (95% confidence interval (CI): 4.5-5.7) in males and 4.1% (95% CI: 3.6-4.6) in females with a low prevalence in those under 20 yr old. Generally, HBsAg seropositivity by administrative area was similar with the exception of Jeju province. HBsAg seropositivity of Jeju island was approximately three times higher in both men and women, as compared with the national average. HBsAg seropositivity by socioeconomic status unexpectedly showed a very consistent positive association in both gender. Comparing HBsAg seropositivity by the frequency of eating out, in both gender, the more frequent they ate out, the higher it was. Our study suggested that there might be another transmission route of HBV, which is possibly related to diet.

OBJECTIVES: The aims of this study were 1) to estimate prevalence rates of drinkers, two subtypes of drinkers-drinkers without dependence and drinkers with probable alcohol dependence(AD) using CAGE, and 2) to find out the correlates of sociodemographic variables and drinking patterns of the drinkers with probable AD by comparing those of the drinkers without dependence, 3) to analyse risk factors for the drinkers with probable AD. METHODS: Using data from face-to-face interviews conducted during 1995, we investigated the prevalence and characteristics of two subtypes of drinkers in a national probability sample of 1,695 drinkers 20 years of age and older. We defined drinkers with CAGE scores 2 and over as drinkers with probable AD, and scores less than 1 as drinkers without dependence. The comparisons of sociodemographic characteristics and drinking patterns between two subtypes of drinkers were examined through chi-square test using weighted data. Statistical analysis including multiple logistic regression analysis were done for each sex, respectively. Because of the large number of coefficients estimated, Bonferroni's method was used to compute p values. RESULTS: The results were as follows: 1) Prevalence of the drinkers was 33.7% in the total sample. Prevalence rate of male and female drinker were 26.3% and 7.40%, respectively. Prevalence of the drinkers with probable AD was 10.9%. For males the prevalence of the drinkers with probable AD was 9.99% and for females 0.94%. 2) According to sociodemographic variables between drinkers without dependence and drinkers with probable AD, males drinkers with probable AD were older, less educated, more depressive, married marital status and were more likely to have occupations of service section than male drinkers without dependence. Female drinkers with probable AD were less educated, more depressive and had less monthly income than drinkers without dependence. 3) As for the drinking patterns, male drinkers with probable AD drank more frequently, had more drinks, had more trying to quit drinking and preferred Soju. Female drinkers with probable AD drank more frequently, had more drinks, were more trying to quit drinking, too. 4) Multiple logistic regression analysis showed that the risk factors for male drinkers with probable AD were lower education(< or =6 years) and depressive symptoms. For females, depressive symptoms and lower education(< or =6 years) were strongly indicative of risk factors though not reaching the statistical significance. CONCLUSIONS: Prevalence of the drinkers with probable AD was 10.9%, and male to female ratio was 10.6:1, which was lower than previous results. Depressive symptoms and lower education proved to be strong predictors for alcohol dependence. This suggest that early detection and treatment of depression and public education for the lower education group should be important.
