Occupational stress is common among nurses. Two factors that may influence stresslevels are diet and physical activity. The purpose of this study was to investigate the diets andphysical activity levels of nurses and to quantify the relationships between these behavioursand anxiety, depressed mood, stress, and burnout. Nurses (N = 52) from one regional hospitalcompleted a survey assessing physical activity, nutrition, and psychological functioning. Almosttwo-thirds (65%) of participants had met recommended levels of both moderate and vigorousphysical activity in the week prior. Participants met recommended levels for fruit, but not veg-etable, consumption. Burnout and stress levels were close to norms for physicians and nurses.Scores for depressed mood, anxiety, and stress symptoms were within one standard devia-tion of norms for the Australian adult population. Several moderately sized correlations werefound between the psychological constructs measured and both physical activity and nutrition.Although most of the participants were physically active and seemed to be consuming nutritiousdiets, some nurses may need encouragement to adopt similarly healthy behaviours.© 2013 Australian College of Nursing Ltd.
