Sleep Duration, Insomnia, and Associated Factors Among Ukrainians 1 Year After Russia's Full-Scale Invasion.

ABSTRACT

OBJECTIVE: We aimed to investigate the prevalence of sleep disturbances and associated factors among Ukrainians 1 year after Russia's full-scale invasion. METHODS: Quota sampling was used to collect online survey data from 2364 adults living in Ukraine aged 18 to 79 years from April 5, 2023, to May 15, 2023. Short sleep duration was defined as sleep duration ≤6 hours and long sleep duration as ≥9 hours. Insomnia was assessed by the Insomnia Symptom Questionnaire. RESULTS: The prevalences of short sleep duration, long sleep duration, and insomnia were 39.4%, 6.9%, and 38.5%, respectively. Short sleep duration and insomnia were both more likely in females (short sleep duration adjusted odds ratio [aOR] = 1.44; insomnia aOR = 2.17), individuals with depression (short sleep duration aOR = 1.61; insomnia aOR = 7.76), affected by the 2014 Russian invasion (short sleep duration aOR = 1.37; insomnia aOR = 1.78), and with more trauma events (short sleep duration quartile 3 [Q3] versus Q1 aOR = 1.88; Q4 versus Q1 aOR = 1.83; insomnia Q3 versus Q1 aOR = 2.14; Q4 versus Q1 aOR = 2.32). Insomnia was more likely in Ukrainians with posttraumatic stress disorder (aOR = 2.95), anxiety (aOR = 4.57), and loneliness (aOR = 1.67). Essential public service was associated with short sleep duration (aOR = 1.64). Short sleep duration and insomnia were associated with lower quality of life in physical, psychological, and environmental domains. Insomnia was associated with the social relationships domain. CONCLUSIONS: Sleep health among Ukrainian adults 1 year into the war is concerning, with more than one-third reporting inadequate sleep or insomnia. More studies are needed on impacts and interventions for sleep health during and after the war.
