However, little is known about how patients' understanding of BMI has progressed/changed in the last several years. The primary purpose of this study was to determine the change in patients' knowledge of BMI and weight-related risk factors. A secondary outcome of this study was to determine the incidence of physician discussion about BMI with the patient.Methods: We administered an anonymous survey to primary care patients in 33 rural family medicine clinics in 2013 and 2017. The survey included 8 questions regarding BMI knowledge and 5 demographic questions.Results: A total of 573 patients completed the survey. There were 345 participants from 2013 and 238 from 2017. The sample included more women than men. There was no significant difference in age or proportion of comorbidities across the 2 survey years. Compared with year 2013, more survey participants from year 2017 knew that BMI stood for “body mass index” (71.1% vs 61.2%, P = .02) and understood what medical concerns were related to BMI (65.5% vs 50.7%, P = .0005). The percentages of participants who reported that their doctor ever discussed BMI with them went up from 20.1% to 28.7% (P = .02).Conclusion: In this cross-sectional cohort study, it was found that patients' knowledge about BMI and weight-related risk factors has increased modestly. However, despite the increase in patients' knowledge and discussions about BMI with their primary care physician, there was not a decrease in BMI. Future studies are needed to provide more detailed information about the discussion between patients and providers in relation to the patient's personal weight status. %U https://www.jabfm.org/content/jabfp/32/3/413.full.pdf
