Sleep, chronotype, and quality of life of shift duty workers in tertiary care center of Saurashtra

Abstract

Abstract Background: Insomnia in shift work has been associated with impairment in health and social life and poor quality of life among shift workers. Aims and Objective: The study aimed to assess insomnia, chronotype, and quality of life in nursing shift duty workers and to find an association among insomnia, chronotype, and quality of life in nursing shift duty workers of a tertiary care center in Saurashtra. Materials and Methods: A cross-sectional study was carried out among 300 nursing shift duty workers. Consented participants with at least one-night duty per week were included in our study. A semistructured proforma containing basic demographic details and scales such as ‘Insomnia Severity Index’ (ISI), ‘Composite Scale of Morningness,’ and ‘world health organization quality of life’ were distributed among all participants. Associations were examined by using t test and Chi-square test. Results: The prevalence of insomnia was 42.66% in this study. A total of 27.33% of participants were having mild insomnia, whereas 15.33% were having moderate-to-severe insomnia. Insomnia severity was statistically significantly associated with needle stick injury (p = 0.003) and years of shift work (0.031). Insomnia severity had been significantly associated with the chronotype of participants, negative but statistically significant correlation was found between the ISI score and mean score of all four domains of world health organization quality of life. Conclusion: Insomnia in shift work has been associated with evening chronotype and poorer quality of life of shift workers. Therefore, the management of insomnia is important for a better quality of life for shift workers. Participants with insomnia are more prone to needle stick injury during work.
