Título

Effect of the rotating shift on the sleep parameters of military police officers

Introdução

Military police officers are among the classes of workers who carry out their activities at unconventional times, since police service is considered essential. With the changes in working and sleeping hours, workers are susceptible to sleep disorders, high levels of occupational stress and physical and mental illness.

Objetivo

To analyze the effect of working hours on the sleep parameters of military police officers.

Métodos

The research was conducted with 22 military police officers from Rio Branco between February and July 2023. Sleep variables were measured using actigraphy and sleep diaries for 14 days. Sociodemographic, work-related, lifestyle and chronotype variables were also collected. Considering the assumption of normality, repeated measures ANOVA and Friedman’s test were used. Tukey’s and Durbin-Conover’s tests were used for post-hoc analysis.

Resultados

On daytime working days, police officers slept an average of 7.92 h (SD ±1.59); while, on nighttime working days, they slept an average of 5.47 h (±1.93); and, on non-working days, 6.64 h (±1.24). Sleep efficiency after day work, night work and day off was 88.6% (±6.57), 83.6% (±6.07) and 84.6% (±7.91), respectively. Total main sleep time was higher on daytime working days, when compared to nighttime working days (p <0.001) and days off (p <0.001), and lower on nighttime working days when compared to days off (p <0.001). Total time in bed revealed differences when comparing day and night work (p <0.001), day work and day off (p <0.001) and night work and day off (p = 0.008). Differences were also observed in the average total sleep time between day and night work (p <0.001), day work and day off (p <0.001) and between night work and day off (p = 0.004). Average sleep efficiency was higher on daytime working days, when compared to nighttime working days (p = 0.009) and non-working days (p = 0.022). The average time awake after variable sleep onset was higher on daytime work days, when compared to nighttime working days (p = 0.006), and higher on daytime working days compared to non-working days (p <0.001).

Conclusões

Sleep is influenced by working hours, with the night shift having the greatest impact on police officers’ sleep, resulting in shorter sleep duration and lower sleep efficiency.
