Analysis of American Medical Students' Knowledge of Physical Activity Recommendations

The benefits of physical activity (PA) are widely recognized; American medical schools have begun to emphasize PA, but the effectiveness of these changes is unclear.

We performed a cross-sectional analysis of medical students enrolled in US osteopathic and allopathic medical schools between August 2019 and May 2020. All participants completed an electronic survey about PA instruction across the 4 years of medical school. Objective information including hours and format of PA instruction was collected. Subjectively, participants reported their relative comfort discussing various aspects of PA education with patients.

A total of 480 medical students completed the survey, representing 82 of the 192 US medical schools (69 allopathic, 13 osteopathic). Students are more comfortable discussing overall exercise benefits than exercise testing, exercise prescription, and exercise physiology (P<.0001). They also report more exposure to general PA guidelines related to overall PA duration than strength training (P<.0001). Students at allopathic and osteopathic schools reported similar outcomes regarding PA education, while students with class sizes under 200 reported increased familiarity with National Physical Activity Guidelines regarding PA duration (P<.0001) and strength training (P=.01).

Despite recent efforts to improve PA education in medical school, students feel unprepared to apply their knowledge in a clinical setting and remain unaware of national PA guidelines. Future studies should determine how to practically integrate PA education longitudinally into curricula to change PA education from an afterthought to an essential component of medical school education.
