Objective: To examine the prevalence and associated factors of insomnia among healthcare shift personnel.
Methods: A cross-sectional study was conducted between December 2023 and February 2024 at Nopparat Rajathanee Hospital, involving physicians, pharmacists, nurses, medical technologists, and supporting staff. Participants were selected through stratified sampling. Questionnaires included demographic information, work patterns, and the Thai version of the Athens insomnia scale (AIS). Data were analyzed using descriptive statistics, chi-square test, and logistic regression.
Results: Among 279 participants, 59.1% (95% CI = 53.1 - 65.0) met the criteria for insomnia (AIS ≥ 7). Factors that increased the likelihood of insomnia included sleeping less than 4 hours per day (AOR = 7.51, 95% CI = 2.09 - 27.01) and 4 - 6 hours per day (AOR = 3.47, 95% CI = 1.71 - 7.02), compared to sleeping more than 6 hours per day, working mainly in inpatient units (AOR = 2.84, 95% CI = 1.02 - 7.93), working 201 - 300 hours per month (AOR = 2.72, 95% CI = 1.04 - 7.06) compared to working no more than 200 hours per month, and working 11 or more night shifts per months (AOR = 1.89, 95% CI = 1.01 - 3.55).
Conclusion: The healthcare shift personnel are at risk of insomnia associated with their work schedules. The findings highlight the need for adjustments to work-rest schedules and increased health support to enhance their quality of life and mitigate the adverse impacts of insomnia on their well-being.
