abstract="The purpose of this study was to clarify the sleep disorders and sleep conditions among workers in a company through descriptive statistics. We analyzed the data of individuals with suspected sleep disorders based on the 1-year outpatient health insurance claim data of 2,800 employees in a company in Japan. We conducted a questionnaire survey to find out sleep condition and drug usage of the same participants. Claim data of 339 employees (12.1%) were selected for analysis, and the breakdown of diseases comprised 153 (5.5%) with sleep disorders, 149 (5.3%) with headache, 119 patients (4.2%) with depression, and 17 (0.6%) with autonomic imbalance. We recovered 2,608 questionnaire responses (93.0%) and found that 1,852 subjects (71.0%) were aware of insomnia symptoms within one year. Our findings highlight the prevalence of sleep disorders and drug usage among workers in a company, and the conditions of these disorders, including the awareness of insomnia.<p /> <p>Language: en</p>",
