Background: Insomnia is one of the important issues in public health because it has clinically and socioeconomically impacts to society.: Regarding the factors affecting insomnia, although the effects of each clinical factor on insomnia have been studied individually, few research reports have simultaneously examined socio-economic factors, especially in Japan.: In this study, we comprehensively examine various effects that affect insomnia.: In particular, it examines factors that have not been noticed so far from a socio-economic viewpoint as well as a clinical viewpoint.: Methods: In this study, we used data from a questionnaire survey conducted in 2013 to explore clinical and socioeconomic factors that correlate with insomnia. This sample population is expected to represent people aged 18 years or older living in Japan. Athens Insomnia Scale (AIS) was used as an outcome index, and related factors were searched for in two groups, with/without "insomnia tendency," using AIS value 5.5 as a threshold. Because the PHQ-9 also includes questions about sleep, we also examined the collinearity of AIS and PHQ-9. In the sub-analysis, stratified analysis was performed by dividing into two layers, with/without "depression tendency.": Results: 3546 subjects were analyzed, and 920 were classified as with "insomnia tendency," and the proportion in the study population was 25.9%.: In the primary analysis, the factors that showed a statistically significant association with "insomnia tendency" were "age: 40-64 (OR 1.34 [1.03-1.74])," “age: 65- (OR 1.62 [1.16-2.26]),” “with depression tendency (OR 10.59 [8.80-12.75]),” “number of symptoms reported (OR 1.15 [1.09-1.22]),” “currently working (OR 1.32 [1.05-1.65]),” “Not-married (OR 0.67 [0.50-0.89]),” and “living alone (OR 1.65 [1.10-2.48]).: Conclusion: It is suggested that not only clinical factors, but also socioeconomic factors play essential roles for early detection of people with insomnia.: Keywords: Insomnia, AIS, Health Literacy, Occupation, Health Diary, Japan, Self-reported |
