Abstract

Aim: Shift work expands globally and it has become necessary to increase productivity and provide continuously service in various sectors like industry. It has been identified as an important risk factor in the etiology of metabolic disorders and chronic diseases. The aim of this study was to investigate the association of sleep quality and depression with nutritional status of shift workers.

Methods: A total of 170 male rotating shift workers of an industrial organization aged between 20 - 55 years participated in this study. A questionnaire which consisted of demographic and lifestyle characteristics was used. Weight, height, waist and neck circumferences (WC and NC) of participants were measured, and body mass index (BMI) and waist-to-height ratio (WHtR) were also calculated. Body composition was assessed using bioelectrical impedance analysis. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI), while anxiety and depression were estimated through Hospital Anxiety and Depression Scale (HADS) questionnaire.

Results: The average age of participants was 40.1 ± 6.87 years. Among the 170 shift workers, 44.7% of them were pre-obese, and 35.3% were obese. As BMI increased, the percentages of poor sleep quality increased. There were positive correlations between PSQI score and WC, WHtR and body fat mass, and a negative correlation between total body water, which were found to be statistically significant. There was no relationship between depression and BMI, WC, WHtR and body fat mass. Participants with depressive symptoms had significantly higher prevalence of risk based on NC. HAD-D score was inversely correlated with fat free mass.

Conclusion: This study showed that pre-obesity and obesity is common in shift workers. The previously reported relationship between obesity and poor sleep quality is supported. Sleep quality get worse as WC, WHtR and body fat mass increase, while total body water decrease. Decrease in fat free mass is associated with the development of depressive symptoms. These associations need to be verified in large studies. Based on the results, appropriate strategies including both employer and worker should be performed to reduce the detrimental health outcomes associated with shift work.
