Sleep Habits and Insomnia-Associated Factors in Korea Adult Population: A Cross-sectional Survey of Three Rural Communities

Abstract: Objectives: We attempted to study sleep habits and insomnia-associated factors in Korean rural adult population. Methods : In 1,441 adult subjects of three rural communities selected by cluster sampling, we administered an epidemiologic survey using questionnaire methods from July 14, 1996 to July 28, 1996. Results : 1) Mean sleep latency and mean time to sleep again after awakening during nocturnal sleep were longer in females than in males. Females suffered more frequently from insomnia symptom, awakening during nocturnal sleep. morning headache, dysphoric mood in the morning, and the feeling of 'not refreshed' on waking-up than males. 2) The older age group (defined as those older than 65 years) was found to have earlier bed-time, longer sleep latency, more frequent nocturia, longer time to sleep again after awakening during nocturnal sleep, and more frequent insomnia symptom. 3) The presence of insomnia symptom more than once a week was significantly associated with suffering from physical illness, being divorced-separated-widowed, frequently feeling depressed, nocturia, or low education level. 4) In multiple logistic regression analysis, old age, being female, low education level, frequently feeling depressed, and nocturia were independently associated with the presence of insomnia symptom more than once a week. Conclusion : We conclude that, in a Korean rural adult population, insomnia symptom increases with age and females usually suffer more from insomnia symptom than males. In addition, low education level, feeling depressed mood frequently, and nocturia are found to be significantly associated independently with the presence of insomnia symptom more than once a week.

Seroepidemiologic Study of Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) Infection among Koreans in Rural Area, Korea

Abstract: To estimate the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection and to determine associated risk factors, a population-based seroepidemiologic study was carried out In 1993, a health examination survey of the population was carried out in rural area known to have a high incidence of liver cancer The study population were those who volunteered to participate in a health survey over 10 years of age Examinees were interviewed by specially trained staffs Sera from 1,033 study subjects were tested for hepatitis B surface antigen (HBsAg) by everse passive hemagglutinin (RPHA) estimation and for hepatitis C virus antibody (anti-HCV) by 2nd generation passive hemagglutinin (PHA) estimation The age and sex standardized prevalence of HBsAg was 63% which was similar to national average, but that of anti-HCV was 51% which was 4 to 5 times higher than that of blood donors or other health examinees in Korea In a multivariate analysis, transfusion history, surgical operative history, and acupuncture history were not associated with HBsAg positivity In contrast, acupuncture history (adjusted odds ratio[OR]=22 : 95% Confidence interval[CI] 10-47) and surgical operative history(adjusted OR=20 : 95% CI 10-41) were associated with anti-HCV positivity The present study suggest that there is an highly endemic area of HCV infection in Korea and probably this endemicity is associated with a parenteral source of HCV infection other than blood transfusion

Health related practices and morbidity among adult in rural area

Abstract: This research was carried out to determine the performance rate of health related practices, to measure the agreement between morbidity by doctor's diagnosis and morbidity by subject' self-reported and the degree of association between health related practices and morbidity rate by doctor's diagnosis, to identify their effects on morbidity among rural area populations. The data were gathered by volunteer residents (over the age of 20) of Haman Myeon, Haman Gun, Kyeongsangnam Do in Korea, from June 10, 1993 to June 12, 1993 (369 male and 516 female). Face to face interview, lab, chest P-A, EKG and physical examination were completed. Descriptive statistics, agreement analysis and multiple logistic regression procedures were employed for analyses. The results of the study were summarized as follows : 1) Age adjusted morbidity rates by doctor's diagnosis and self-reported were 38.5% (male:37.3%, female:36.5%), 26.4% (male:33.3%, female:27.5%), respectively. Kappa coefficient between morbidity by doctor's diagnosis and morbidity by self-reported was 0.21 (male:0.21, female:0.22). 2) The frequency of disease by doctor's diagnosis was as follows: hypertension(15.3%), gastritis (9.6%), diabetes mellitus (8.5%), live. disease (8.1%), and degenerative arthritis (6.2%) in the study population. 3) Order of health practice performance rate was as follows: Males-normal body weight (62.1%), non-heavy alcohol consumption (57.5%), 7-8 hours of sleeping (50.1%), non-smoking (21.7%), and exercise (19.8%). Females- non-heavy alcohol consumption (97.3%), non-smoking (84.7%), normal body weight (57.8%), 7-8 hours of sleeping (45.0%), and exercise (9.9%). 4) There was no significant relationship between health related practice and morbidity except exercise among health related practices. 5) Health related practice index which was recategorized by high, medium, and low had effects on the probability of developing morbidity.
