Association between Occupational Heat Exposure Levels and Sleep Disturbance among Construction Workers Aged 60 Years and Older
Purpose: This study examined the association between occupational heat exposure and sleep disturbance among construction workers aged 60 years and older. Methods: Data from the 7th Korean Working Conditions Survey (2023) were analyzed. The original seven heat-exposure categories were retained. A two-stage complex survey design incorporating strata, enumeration districts, households, and standardized weights was applied. Descriptive analyses included 750 workers, and the complete-case multivariable analysis included 736 workers. Results: In the fully adjusted model, the overall effect of heat exposure was significant (Wald F=2.626, p=.016). Compared with no exposure, sleep-disturbance scores were higher among workers exposed for 1/2 of working time (B=.214, p=.029), almost all working time (B=.314, p=.005), and all working time (B=.642, p=.008). A significant linear trend was observed across the ordered exposure categories (B=.057, 95% CI=.022–.092, p=.002), although category-specific estimates were not completely monotonic. Conclusion: Occupational heat exposure was significantly associated with sleep disturbance among older construction workers after adjustment for sociodemographic characteristics, self-rated health, and well-being.
