简要总结
Currently, residents commonly experience dehydration and poor nutrition during nighttime duty hours as a result of heavy work load, lack of time to take nutrition and hydration breaks, or limited or no access to healthy food and drinks which may affect residents' work performance. The goal of this study is to compare the effects of two different meal compositions with no typical dietary practices (existing conditions) on work performance of the on-call residents during night shifts.
详细描述
The purpose of this study is to determine the effects of dietary modifications on resident physicians' work performance during night shifts.
Specific objectives are:
- To assess the effects of macronutrient composition of the test meals on cognitive performance, self-reported sleepiness and fatigue of resident physicians during night-time duty.
- To compare to no intervention, the effects of providing meals before 22:00 hours, and only providing chewing gum, tea, coffee and water onwards to on-call residents, on cognitive performance, self-reported sleepiness and fatigue of resident physicians during night-time duty.

结局指标
主要结局
Difference in Fractal 2-Back between conditions
时间窗: Two time points (beginning and end of night shifts) on each night for a total of 3 nights
Fractal 2-Back is a validated neurocognitive test that assess working memory. This test takes approximately 2 minutes to complete and will be measured at two time points (beginning and end of each night shift) in each of the 3 conditions. Differences in reaction time (in milliseconds, lower reaction time is better) , accuracy (percentage of correct responses, a higher percentage is better) and composite scores (0-1000, higher score is better) will be reported and compared.
Difference in Motor Praxis scores between conditions
时间窗: Two time points (beginning and end of night shifts) on each night for a total of 3 nights
Motor Praxis is a validated neurocognitive test that assesses sensory-motor speed. This test takes approximately 30 seconds to complete and will be measured at two time points (beginning and end of each night shift) in each of the 3 conditions . Differences in accuracy (percentage of correct responses, a higher percentage is better), duration (in milliseconds, lower duration is better), reaction time (in milliseconds, lower reaction time is better) and composite scores (0-1000, higher score is better) will be reported and compared.
Difference in Psychomotor vigilance test between conditions
时间窗: Two time points (beginning and end of night shifts) on each night for a total of 3 nights
Psychomotor vigilance test is a validated neurocognitive test that assess vigilant attention. This test takes approximately 3 minutes to complete will be measured at two time points (beginning and end of each night shift) in each of the 3 conditions. Differences in reaction time (in milliseconds, lower reaction time is better), lapses (number, less is better) and composite scores measured (0-1000, higher score is better) will be reported and compared.
Difference in Balloon Analog Risk between conditions
时间窗: Two time points (beginning and end of night shifts) on each night for a total of 3 nights
Balloon Analog Risk is a validated neurocognitive test that assess risk decision making. This test takes approximately 2 minutes to complete and will be measured at two time points (beginning and end of each night shift) in each of the 3 conditions. Differences in risk propensity (higher scores indicative of greater risk-taking propensity), duration (in milliseconds, lower reaction time is better) and composite scores (0-1000, higher score is better) will be reported and compared.
次要结局
- Difference in Degree of sleepiness between conditions(Two time points (beginning and end of night shifts) on each night for a total of 3 nights)
