Diet quality in medical trainees: a cross-sectional assessment comparing medical students and primary care residents using the Rapid Eating Assessment for Participants-shortened version.

Background: The diet quality of the US population is significantly unhealthy, with critical long-term implications for the nation's health. A few studies have explored diet quality in the future primary care workforce. This cross-sectional study quantifies the diet quality of medical students and primary care residents at a Midwestern college of medicine in the United States.

Methods: 250 medical students and 148 primary care residents were surveyed electronically utilizing the Rapid Eating Assessment for Participants-Shortened Version (REAP-S). The survey consists of 13 questions that can be scored on a scale from 1 to 3, along with 3 questions that are not scored. The average REAP-S score for a US omnivorous diet is 32 (range 13 to 39) with higher scores indicating a higher quality diet. We obtained average REAP-S scores for all respondents and descriptive summary statistics for individual REAP-S items. Students' REAP-S total scores were compared to those of residents and the interaction between student/resident status and BMI category on REAP-S total scores were analyzed using analyses of variance. Differences between students and residents on BMI categories and other outcomes (individual REAP-S items, pandemic dietary and weight changes) were analyzed using Chi-Square Tests of Independence or Fisher's Exact Tests.

Results: Medical students (n = 99; 39.6% response rate) had a significantly higher mean REAP-S score (30.5, SD = 3.9) than primary care residents (n = 72; 49% response rate) (mean = 28.6, SD = 3.9; p = 0.006). Total mean REAP-S scores were significantly higher for those with BMI < 25 (mean = 30.8, SD = 3.7) than for those with BMI > = 25 (mean = 28.3, SD = 4.0; p < 0.001). There was not a statistically significant interaction between role (student vs. resident) and BMI category on total REAP-S scores (p = 0.39). Most respondents (89.3%) indicated that they were willing to improve their diet.

Conclusion: Our data suggest that the diet quality of surveyed medical students and primary care residents, as quantified by the REAP-S, is suboptimal. Early detection and improvement of diet quality may be necessary for our medical profession trainees to avert potential long-term adverse cardiometabolic health outcomes, and to optimize the health of our future primary care workforce.
