Curbing excess gestational weight gain in primary care: using a point-of-care tool based on behavior change theory

Excess gestational weight gain (GWG) is a risk factor for several adverse outcomes for mothers and their offspring. In Nova Scotia, Canada, approximately 60% of women experience excess GWG. Outside the pregnancy arena, a patient-centered approach has been shown to promote increased patient adherence to clinician recommendations, and increased intentions for, and attempts at, behavior change. The 5As of Healthy Pregnancy Weight Gain is a tool that assists clinicians to have patient-centered discussions about GWG. This feasibility trial examined the association between training in the use of this tool and women's self-efficacy to manage GWG, readiness to adhere to GWG guidelines, perception of their clinicians' patient-centeredness when discussing GWG, and guideline concordance of total GWG.

Participants were 11 family physicians who provide prenatal care and 24 of their patients who were pregnant. Physicians were randomly assigned to a single 60-minute training session in the use of the tool or usual care. Consenting patients completed measures of social support, stress, patient-perceived patient-centeredness, self-efficacy, and motivation. At the end of each woman's pregnancy, data pertaining to guideline concordance of GWG were collected.

Comparison of patient participants with prenatal care providers in the trained and untrained groups showed no significant difference in patient-perceived physician patient-centeredness when discussing GWG, self-efficacy to manage GWG, readiness to adhere to GWG guidelines, or GWG congruence with the guidelines.

This feasibility study required very little time commitment and entailed minimal disruption to clinicians' practices. Nonetheless, it was very difficult to recruit clinicians for the study. Although recent theory-driven work showed that prenatal care providers have, overall, high perceived self-efficacy in discussing GWG with their patients, most studies have demonstrated that these providers do not often discuss GWG with their patients; so, there is clearly a mismatch in their perceived self-efficacy and what actually transpires.
