Abstract

This was a retrospective matched cohort study aimed to compare the prevalence of health conditions related to non-communicable diseases (NCDs) between healthcare personnel working in shift schedules (SW) and those working only regular daytime hours (DW) at Udon Thani Hospital (UTH). Participants were healthcare personnel. Data collected from annual health check-up in year 2025. Eligible participants with complete data were divided into SW and DW groups. Matching was performed in a 1:1 ratio based on age and sex. Health outcomes consisted of body mass index (BMI), blood pressure (BP), fasting plasma glucose and lipid levels. The prevalence of obesity, diabetes mellitus (DM), hypertension (HT), and dyslipidemia (DLP) were compared between groups.

               Results: A total of 3,574 individuals were recruited. There were 2,158 and 1,416 cases in SW and DW, respectively. Three-quarter (74.20 %) of subjects were female. SW had a lower median of age (33 versus 37 years old), higher prevalence of regular exercise than DW (73.96% and 70.20%, p-value =0.014). The prevalence of DLP, obesity, HT and DM were 62.44, 38.53, 12.43 and 9.89 %, respectively. SW had significantly higher obesity than DW (aOR= 1.56, 95% CI: 1.22-2.00, p < 0.001). Risk of DM, HT and DLP of both groups were comparable.

               Conclusion: The prevalence of DLP, obesity, HT and DM were 62.44, 38.53, 12.43 and 9.89 percent, respectively. SW had higher risk of obesity than DW.
