Abstract
BACKGROUND: Night-shift work may adversely affect health. This study aimed to determine the impact of night-shift work on health-related quality of life (HRQoL) and assess whether sleep quality was a mediating factor. METHODS: A cross-sectional study was conducted among Malaysian manufacturing workers, aged 40 to 65 years. Participants completed a self-administered questionnaire on socio-demography and lifestyle factors, short Form-12v2 Health Survey (SF-12), and the Pittsburgh Sleep Quality Index (PSQI). Baron and Kennys method, Sobel test and multiple mediation model with bootstrapping were used to determine whether PSQI score or its components mediated the association between night-shift work and HRQoL. RESULTS: Of the 494 participants, 177 (36%) worked night-shift and 51% were males. Mean age was 47±5 year. Night-shift work was associated with sleep impairment and HRQoL. Night-shift workers had significantly lower mean scores in all the eight SF-12 domains. Compared to non-night shift workers, night-shift workers were significantly more likely to report poorer sleep quality, longer sleep latency, shorter sleep duration, sleep disturbances, and daytime dysfunction. Mediation analyses showed that PSQI global score mediated the association between night-shift work and HRQoL. Subjective sleep quality and sleep disturbances were mediators for the association between night shift work and physical wellbeing, whereas sleep latency and daytime dysfunction were mediators with respect to mental wellbeing. CONCLUSION: Sleep quality partially explains the association between night-shift work and poorer HRQoL. Organisations should treat the sleep quality of night-shift workers as a top priority area for action in order to improve their employees overall wellbeing
