Influence of Shiftwork on Association between Body Mass Index and Lifestyle or Dietary Habits in Female Nurses and Caregivers

Abstract

The present study examined the influence of shiftwork on lifestyle and diet in female nurses and caregivers. The subjects were 134 female nurses and caregivers aged 20-63 years, who completed a self-administered questionnaire pertaining to lifestyle and dietary habits. We found that shift workers consumed more sweet beverages and snacks than day workers. In addition, shift workers reported irregular lifestyles between shifts. The number of shift workers who missed breakfast or lunch was higher on days at the start and end of night shift than on days during the day shift. Moreover, in shift workers, we identified a significant and positive correlation between the number of years engaged in shiftwork and body mass index.
