説明
This study assessed the impact of insomnia on individual health dissatisfaction in Japan, South Korea, and Taiwan.Cross-sectional surveys with a face-to-face interview were conducted in Japan (n = 1414), South Korea (n = 1007), and Taiwan (n = 785). Participants completed a questionnaire on general health dissatisfaction and insomnia symptoms. Insomnia was defined as having at least one of three types of insomnia symptoms (i.e., difficulty initiating sleep, difficulty maintaining sleep, and early-morning awakening). Information on sociodemographic characteristics (i.e., sex, age, education level, and household income) was also collected.N/A.A nationwide sample of subjects aged 20 years or olderN/A.The age-adjusted prevalence of insomnia "lasting more than 2 weeks" was 4.0% in Japan, 9.9% in South Korea, and 10.3% in Taiwan. Insomnia was an independent contributor to health dissatisfaction after adjusting for sociodemographic characteristics in the three countries, with odds ratios of 2.54 (95% CI, [1.51-4.28]) in Japan, 2.15 (95% CI [1.33-3.48]) in South Korea, and 2.31 (95%CI [1.37-3.89]) in Taiwan. A multivariate logistic analysis showed that the sociodemographic characteristics that significantly influenced health dissatisfaction varied among nations-including older age and low education level in Japan and female gender and middle-income level in South Korea. No independent variables were selected in Taiwan.Insomnia is closely linked to health dissatisfaction in the three Asian countries, with variation according to social and demographic factors.
