Sleep, dietary intake and physical activity changes with onset of shift work in intern paramedics

Abstract
Paramedic work is associated with high staff turn-over, insufficient sleep and adverse health outcomes. Our understanding of the relationship between paramedic work and the health behaviours that may precede adverse health outcomes is limited, as few longitudinal studies have examined health behaviours in workers before they commence on the road work. Such research is needed to inform evidence-based recommendations specifically for new paramedics. The current observational cohort study examined self-reported sleep, dietary intake and physical activity in 21 intern paramedics: 15 female and 6 male (median age: 23.0 years [interquartile range (IQR): 4.0]) from an Australian ambulance service. A subset of participants ( n = 16) provided fasting blood samples for cardiometabolic markers (cholesterol, triglycerides and fasting glucose). Data were collected quarterly (pre-shift work, 3 months, 6 months, 9 months and 12 months post commencement). Linear mixed models showed that the first 12 months of shift work were associated with poorer sleep quality ( p = .036), consumption of fewer kilojoules ( p = .026), reduced saturated fat consumption ( p = .005) and lower sodium ( p = .043) and sugar ( p = .038) intake. There were significant increases in leisure time physical activity ( p = .008). This study shows negative changes in sleep quality and improvements in diet and leisure time physical activity during the first 12 months of paramedic work. Individual differences observed in this study, and ongoing suboptimal dietary intake, highlight a need for larger studies with more participants and a focus on personalised strategies for new recruit paramedics.
