Examining Enhanced Implementation of Routine Antenatal Care Practices to Support Healthy Pregnancy Weight Gain

Abstract

IntroductionCurrent antenatal guidelines advocate for regular weighing of women during their pregnancy, with supportive conversations to assist healthy gestational weight gain (GWG). To facilitate overcoming weight monitoring barriers, a pregnancy weight gain chart (PWGC), coupled with brief intervention advice, was implemented in 2016 to guide provider and woman‐led routine weight monitoring. This study aimed to examine the extent to which the use of PWGCs and routine advice provision were normalized into routine antenatal care following enhanced implementation strategies and whether this led to a change in GWG.MethodsThis pre‐post study included data from 2010 (preimplementation), 2016, and 2019 (postimplementation). A retrospective audit of health records and PWGCs was undertaken to assess adherence to chart use and evaluate GWG outcomes. A survey was sent to women in 2010 and repeated in 2019 to understand the advice women received from health care professionals.ResultsCompared with the preimplementation cohort (2010), more women achieved a healthy GWG in 2019 (42% vs 31%,P= .04). In 2019, having 3 or more weights recorded was associated with a reduction in excess GWG (P= .028). More women reported receiving helpful advice about healthy GWG in 2019 compared with 2010, although minimal changes to advice received about nutrition and physical activity were observed.DiscussionEnhanced implementation strategies and ongoing efforts to optimize supportive antenatal care practices are required to effect positive change in GWG. Further evaluation of the perspectives of pregnant women and counseling practices of health professionals is needed.
