title: Weight gain and body mass index following change from daytime to night shift - a panel study with nursing professionals.
abstract: We analyzed the association between change in work schedule and modifications in nutritional status. We performed a panel study with nursing professionals based on two surveys seven year apart (n = 372). Groups with no change in work schedule, change from daytime to night shift, and change from night to daytime shift were analyzed. Outcomes were weight gain and body mass index (BMI) category increase. Participants who changed from daytime to night shift showed about twice increase in odds of more than 5 kg weight gain and BMI category increase. Changing from daytime to night work seems to influence weight and BMI.
