BACKGROUND Sleeping habits are relevant to the health of medical residents as sleep‐deprivation has been linked to increased energy intake and obesity risk. OBJECTIVE To evaluate effects of nights on call and amount of sleep time on dietary intake of anesthesiology residents. METHODS 27 anesthesiology residents were recruited to participate in this crossover design study evaluating dietary intake on two occasions, 1) after receiving ≥8 hours of sleep and 2) after receiving ≤4 hours of sleep on‐call. Dietary data were collected at two breakfast buffets where participants were allowed to select food choices ad‐libitum. Food items were weighed previous to and after service, including plate waste. 24‐hour food recall was utilized to collect dietary intake data for the rest of that day. Participants were unaware that dietary intake was evaluated at each breakfast buffet. RESULTS 20 participants (15 M, 12 F; 32 ± 5.6 years) completed the study. No significant difference was observed between total energy (791 ± 672.8 kcal vs. 737.5 ± 470.5 kcal) or macronutrient intake. Intake of fat as percent of energy greater than IOM recommendations was observed in the sleep‐deprived group (36.9 ± 8.3%). CONCLUSION Sleep‐deprivation related to on‐call shifts did not result in increased energy intake by anesthesiology residents; however, sleep‐deprivation was related to greater than IOM recommended fat intake as percent of energy.
