Abstract:
Objective:To explore the prevalence and risk factors of insomnia in Chinese Air Force servicemen deployed to highland areas.Methods:A total of 718 Air Force servicemen deployed to Qinghai-Tibetan plateau were recruited at May 2024.Sleep quality was assessed with the Pittsburgh Sleep Quality Index.Social-demograph-ic,military service,and psychological characteristics were measured with a self-administered general question-naire.Bivariable and multivariable logistic regressions were performed to identify independent risk factors.Missing data were handled by the multiple imputation.Results:The average sleep duration was(6.9±1.2)h and the aver-age PSQI score was(5.9±4.1).Totally 53.8%of participants experienced clinically significant insomnia.The multivariable analysis revealed that age≥35(aOR=4.07,95%CI=1.11-17.76),stressful event(aOR=3.27,95%CI=2.00-5.49),dysfunctional sleep beliefs and attitudes(aOR=2.59,95%CI=1.75-3.85),and caffeine product usage(aOR=1.69,95%CI=1.17-2.43)were risk factors for insomnia,while Tibetan-indigenous ethnic(aOR=0.44,95%CI=0.20-0.91),higher perceived social support(aOR=0.96,95%CI=0.96-0.99),and positive coping style(aOR=0.96,95%CI=0.93-0.99)were protective factors.Conclusion:Air force service-men deployed to highland areas have sufficient sleep time,but reduced sleep quality.Age,exposed to stress event during deployment,dysfunctional sleep beliefs and attitudes,and caffeine product usage are risk factors for insomni-a,while Tibetan-indigenous ethnic,higher perceived social support and positive coping style act as protective fac-tors.
