A key finding of this study was the consensus among the participating physicians regarding what they perceived to be the common barriers to helping patients adhere to a health-promoting lifestyle. Consistent with past research [8,9], the 3 most common barriers cited by the participating physicians were that they did not have enough time, patients were not interested in improving their weight, and adequate referrals for diet, physical activity, and weight were lacking. Additional barriers endorsed included a lack of effective tools and information to give patients, and a fear of offending patients. Another barrier identified by the participating physicians is the perception that patients had difficulty in changing behaviors necessary for maintaining a healthier lifestyle.
When asked what would facilitate conversations with patients, the top 3 responses given were better tools to communicate diet, physical activity, or weight problems to patients or family members; better mechanisms to connect patients to specific referral sources; and better counseling tools to guide patients towards engagement in healthy lifestyles. Of note is the significant overlap between the perceived barriers and the needed facilitation tools. The clearest example of this overlap is that physicians noted a lack of adequate referral sources to be a barrier and that better mechanisms to connect patients to specific referral sources would facilitate their treatment of patients. Weight management referrals for patients in rural areas and for non-Hispanic black adults and Hispanic adults, among whom obesity is most prevalent in the United States [3,25], are particularly needed. Addressing this need is consistent with national calls to reduce/eliminate obesity and other disparities that plague the U.S. health care system. One promising avenue to facilitate weight management referrals is the development, evaluation, and wide dissemination of remote weight-loss support interventions, particularly in rural, racial/ethnic minority, and low-income communities. Indeed, several recent articles demonstrate the success of such weight management programs across diverse patient populations [27–29].
Many of the physicians who participated in the study (72%) endorsed lack of time as a significant barrier to discussing weight and weight-related behaviors with their patients. Therefore, finding time-efficient strategies to involve physicians in weight management interventions may prove particularly beneficial. One such evidence-based behavioral counseling framework—the 5As framework—has been endorsed by the Centers for Medicare and Medicaid Services and the USPSTF for use with obese patients during a typical 20-minute visit [28].
The second highest-rated barrier, perceived patient lack of motivation, warrants additional discussion. Despite over half of the physicians surveyed citing this as a barrier, previous studies have shown that the majority of overweight patients believe they should lose weight and are interested in losing weight [21]. This study highlights a potential discrepancy between physicians’ perceptions of patients’ interest in weight-loss and their patients’ actual interest. It is possible that this discrepancy can be avoided by training physicians on how to be culturally sensitive when addressing weight with their patients. Moreover, such cultural sensitivity training may be of great use, given that 12% of physicians in this study were apprehensive about discussing weight with their patients due to fear of offending them. Such training typically involves teaching physicians how to talk with patients in ways that enable patients to feel comfortable, trusting, and respectful in patient-physician/provider interactions [29].
