|Abstract:||Objective: To evaluate the prevalence of obesity and weight changes in night shift workers and their relationship with sleep. Methods: Fifty night shift and twenty-six day shift workers were evaluated. They belonged to one of two groups: nurse technicians/assistants or nurses. The night shift started at 7:00 p.m. and ended at 7:00 a.m., while the day shift was either from 7:00 a.m. to 1:00 p.m. or from 1:00 p.m. to 7:00 p.m. Data were collected using sleep diaries, personal questionnaires, scales to measure weight, and height measurement to calculate body mass index (BMI). Results: There were significant differences between the day shift and the night shift groups in sleep latency (6m54s and 20m6s; p<0.001), wakeup call (6h25m and 7h52m; p<0.001), sleep duration (7h12m and 8h21m; p=0.002), quality of nocturnal sleep (8.48 and 7.62; p=0.009), and total nap time (34m48s and 1h30m; p=0.001), respectively. The average BMI-1 (24.57; p=0.015) and BMI-2 (25.63; p=0.033) values from the day shift group were lower than those of the night shift group - BMI-1 (27.01) and BMI-2 (28.04). The frequency of physical activity was correlated with the difference in BMI (r=-0.296; p=0.0366). Conclusions: The night shift workers showed a higher average BMI than day shift workers did. However, it was not possible to ascertain whether sleep alterations influenced the weight gain of night shift workers.|
