The conditional Poisson model for incidence rate ratios (IRR) with 95% confidence intervals (CI) was used for analyses. Based on the international definitions, only a few associations were found: each one-unit increase in weekly working hours and the number of consecutive working days were associated with a lower likelihood of SA. The local definitions were more consistently associated with SA: Each one-unit increase in shift length and time between shifts, higher variation in shift length, and the number of consecutive evening and night shifts were associated with a higher likelihood of SA. To conclude, especially the local definitions of working hour characteristics seem to be important limits for short SA. Thus, high variability of shift lengths and prolonged shifts could be avoided to reduce the risk of SA.

Singapore and Japan have robust workplace safety and health legislative frameworks and laws. However, their approaches diverge because of differing socioeconomic and political contexts. Japan's regulations are generally more comprehensive, require more frequent monitoring of workers' health status, and encompass both physical and mental health components. Singaporean companies focus primarily on the physical component of health, and statutory examinations are required only for exposure to specific occupational hazards. With increasing prominence of mental health issues and shift towards preventive care in Singapore, there will be greater emphasis on a holistic approach to each employee's overall health in future.
