The impact of shift work on nutritional status of police officers

The aim of this study was to show the extent of the influence of the shift work on nutritional status and physical activity of police officers. The research included 130 healthy police officers. The respondents were divided into two groups. The first group included 82 officers who were working the first shift. The second group included 48 officers who were working the 12hour shift. The study used customized questionnaire consisting of questions regarding leisure-time physical activity, self-report lifestyle activity level, body height, body mass, and derived body mass index (BMI). The ANOVA analysis showed that the first shift had significantly lower BMI (2.57 kg/m2 , p = 0.004) than the 12-hour shift. The results showed that physical activity is strongly associated with lower values of BMI in both groups (p < 0.01). Regarding the correlation between age and years of service, only the 12-hour shift showed coherency (p < 0.01). Although there was no difference in the level of physical activity between police officers from different shifts, declines in physical activity were associated with higher values of BMI
