The Healthy Pregnancy Service to Optimise Excess Gestational Weight Gain for Women with Obesity: A Qualitative Study of Health Professionals' Perspectives.

Maternal obesity is associated with health risks for women and their babies, exacerbated by excess gestational weight gain. We describe health professionals' perspectives in the provision of a Healthy Pregnancy service designed to optimise healthy lifestyle and support recommended gestational weight gain for women with obesity. Semi-structured interviews were conducted with health professionals. Questions were based on the Theoretical Domains Framework (TDF) and deductive thematic analysis was performed. A total of 14 multidisciplinary staff were interviewed. Six themes were identified: 1. health professionals view themselves as part of a team; 2. health professionals reported having necessary skills; 3. experience generated confidence in discussing gestational weight gain; 4. gestational weight gain is considered of variable importance; 5. health professionals want women to be comfortable; 6. the environmental context and resources presented some barriers. Staff were supportive of the Healthy Pregnancy service and valued developing teamwork with staff and rapport with women. Most felt relatively comfortable discussing weight gain with women. Barriers included ability to navigate sensitive topics with women, limited awareness of the intervention among new staff, communication between teams, and waiting time for women. Barriers and enablers to the delivery of an integrated model of maternity care were identified. These findings should inform and improve implementation of service models integrating healthy lifestyle in the antenatal care of women with obesity.
