Do primary care physicians use the 5As in counselling obese patients? A qualitative study

Background: Obesity is a global public health problem. A systematic review showed that intensive behavioural counselling is effective in weight management amongst patients with obesity, but little is known if primary care physicians (PCPs) are involved in delivering such counselling. Studies revealed that patients had weight reduction if they were counselled by PCPs who used the 5As (Ask, Assess, Advise, Agree and Assist) method, but PCPs varied in their use of this tool. We aimed to explore the local PCP modalities of obesity counselling and if their approaches and methods corresponded to the 5As tool.Methods: Qualitative data were obtained from interviews with 50 PCPs from public and private primary care practices during six focus group discussions and seven in-depth interviews. The interviews were audio-recorded, transcribed, audited and analysed iteratively based on the grounded theory. Emergent themes were first externally validated, and then finalized after rounds of deliberations amongst the investigators.Results: PCPs varied in their approach in obesity counselling, focusing predominantly on “Ask”, “Assess” and “Advise” in the 5As tool. “Asking” was indirect and “Assessment” rarely covered the effects of obesity on psychosocial functioning. Dietary and lifestyle modifications were the main foci in “Advise”. “Agree” was least performed. Polyclinic doctors tended to “Assist” patients with referral to other healthcare workers for further weight management, but few deliberately “Arrange” to review progress in weight management, citing barriers.Conclusion: PCPs varied in their method of obesity counselling, pending on context and setting of their practices. In contrast to “Ask’, “Assess” and “Advise”, the use of “Agree” and “Arrange” was uncommon.
