Nutrition Education in Internal Medicine Residency Programs and Predictors of Residents' Dietary Counseling Practices

Although physicians are expected to provide dietary counseling for patients with cardiovascular (CV) risk factors such as hypertension, hyperlipidemia, diabetes, and obesity, nutrition education in graduate medical education remains limited. Few studies have recently examined nutrition education and dietary counseling practices in Internal Medicine (IM) residency training.

To conduct a contemporary assessment of outpatient nutrition education in IM residency programs in the United States, identify predictors of residents' dietary counseling practices for CV risk factors, and identify barriers for educators in providing nutrition education and barriers for residents in counseling patients.

Cross-sectional anonymous surveys were completed by IM program directors (PDs) and residents throughout the United States. Linear regression was used to examine the association between the amount of nutrition education received and the number of instruction methods used by the residents and frequency of residents' dietary counseling for patients with CV risk factors.

A total of 40 educators (PDs and ambulatory/primary care PDs) and 133 residents across the United States responded to the survey. About 61% of residents reported having very little or no training in nutrition. Nutrition education in residency, both the amount of education (β = 0.20, P = .05) and the number of instruction methods used (β = 0.26, P = .02), predicted frequency of residents' dietary counseling practices independent of nutrition education in medical school, which was also significantly associated with counseling (β = 0.20, P = .03). Residents' total fruit and vegetable intake likewise predicted frequency of counseling (β = 0.24, P < .001). Low perceived faculty expertise was a major barrier for educators and was associated with lower level of provided nutrition education (r = -.33, P = .04). Low resident and low perceived clinic preceptors' interests in nutrition were also associated with lower frequency of residents' dietary counseling (r = -.19, P = .04; r = -.18, P = .05).

The provision of nutrition education in IM residency programs and IM residents' dietary counseling for patients need to be systematically assessed nationally. This study's preliminary findings suggest that multimodal nutrition education in IM residency and better resident dietary habits are associated with higher frequency of dietary counseling for patients. Lack of faculty expertise and low faculty and resident interests in patient counseling need to be addressed perhaps by mandating nutrition education in graduate and continuing medical education.
