SLEEP TIMING AND CHRONOTYPE OF FOOD WORKERS FROM SCHOOLS, RESTAURANTS AND AGRIBUSINESS

Introdução

sleep timing is influenced by social and environmental factors, such as working timing and light exposure. Food workers are the personnel enrolled in manipulating food in different stages of food business. There is currently a lack of literature on the description of sleep characteristics and chronotype of workers from the food industry.

Objetivo

we sought to describe sleep timing, and chronotype of a sample of food workers from three different working settings however, schools, restaurants, and agribusiness.

Métodos

This study was performed at the municipality of Realeza – PR, a small town located at southwest of the state. We invited food workers from 53 different settings (13 Schools, 16 Agribusiness, 24 Restaurants) to participate in this study. Participants signed consent forms and filled out the Munich Chronotype Questionnaire (MCTQ). Further information on gender and age was also obtained.

Resultados

105 participants aging 39.7±11.3 years old were enrolled. Most of the participants were women (88). There was a higher proportion of men working on Agribusiness setting (26 in total and 13 men), than in Restaurants (45 in total, 3 men), and schools (31 in total) p<0.001. Groups also differ according to the number of working days per week. 91.4% of Restaurant, 84.6% of Agribusiness, and 28% of School workers declared having to work at least 6 days per week (p<0.001). ANOVA did not detect any significant difference for sleep timing during working days (sleep onset, wakeup, sleep duration and mid-sleep time), however, during free days Agribusiness workers woke-up earlier (5:38±1.47), then school (7:26±1.16) and restaurant workers (7:30±1.63) (p=0.01). No significant changes in sleep onset, and sleep duration were found for free days as well (p>0.05), however, there was significant difference for sleep loss between groups (p=0.05), but post-hoc did not reach significance. Chronotype (MSFsc) did not vary significantly between groups (p>0.05), neither Social Jetlag. As expected, Agribusiness workers declared longer duration for light exposure during the week (p<0.01).

Conclusões

Agribusiness workers declared being exposed to natural light longer and wake up earlier than food-workers from School and Restaurants. However, differences might be due gender, or working settings. Further evaluation should consider socio-cultural and gender factors.
