An obesity medicine curriculum increases the obesity care self-efficacy of internal medicine residents in the primary care setting.

Primary care physicians (PCPs) report insufficient knowledge and training gaps in obesity care. Internal Medicine (IM) residency offers an opportunity to address this educational gap for future PCPs. We designed an innovative, multicomponent curriculum on obesity medicine (OM) in the primary care setting for IM residents. We then conducted a prospective, 6-month, two-arm study within two residency programs in Maryland evaluating feasibility (use, appropriateness for IM training, and satisfaction) of the curriculum as well as changes in self-efficacy within seven obesity care domains, assessed on 4-point scales (1-not at all confident to 4-very confident). One residency program received the curriculum and the other served as the control group. We recruited 35 IM residents to participate (17 intervention, 18 control). Among intervention residents, 42% used all curricular components; appropriateness and satisfaction with the curriculum were high. Compared with controls, intervention residents had statistically significant increases in five obesity care self-efficacy domains: nutrition (intervention 0.8 vs. control 0.2, p = .02), behaviour change (1.2 vs. 0.4, p < .01), weight-gain-promoting medications (0.8 vs. 0.1, p = .01), anti-obesity medications (1.2 vs. 0.5, p = .03), and bariatric surgical counselling (0.9 vs. 0.4, p = .03). There were no significant changes in physical activity or post-bariatric surgical care domains. Our OM curriculum is feasible with IM residents and increases residents' obesity care self-efficacy beyond what is achieved with usual IM training.
