Exploring Successful Breastfeeding Behaviors Among Women Who Have High Body Mass Indices

Abstract

Background: Women with high body mass indices are at risk of lower breastfeeding rates but the drivers of successful breastfeeding in this population are unclear. Research Aim: We aimed to (a) explore the barriers and enablers to breastfeeding among women with high body mass indices and (b) map specific behaviors suitable for intervention across the antenatal to postpartum periods. Methods: This was a prospective, cross-sectional qualitative study. We conducted semi-structured interviews with women with high body mass indices who successfully breastfed for 6 months or more ( n =20), partners ( n = 22), and healthcare professionals ( n =19) in Ireland during 2018. Interviews were audio recorded, and transcribed verbatim. Data were inductively coded using reflexive thematic analysis and deductively mapped within the Capability, Opportunity, Motivation–Behavior model. Results: The three themes developed were knowledge, support, and self-efficacy. Knowledge supported a participant’s psychological and physical capability to engage in breastfeeding. Support was related to the social and physical opportunity to enable performance of breastfeeding behaviors. Self-efficacy influenced reflective and automatic motivation to perform breastfeeding behaviors. A multifactorial intervention design is needed to support successful breastfeeding. Conclusion: The barriers and enablers identified for participants with high body mass indices were similar to those for the broader population; however, the physicality and associated social bias of high body mass indices mean that additional support is warranted. Antenatal and postpartum breastfeeding services need a multifaceted, inclusive, and high-quality program to provide the necessary support to women with higher body mass indices.

Pregnancy as an opportunity to prevent type 2 diabetes mellitus: FIGO Best Practice Advice

“…These findings suggest that promotion of a combination of breastfeeding, diet, and physical activity could diminish maternal type 2 diabetes risk without compromising infant growth and might be particularly important in women with a history of GDM. Breastfeeding can be more challenging among women with higher BMI and they may require additional lactation support 56 …”

“…Several randomized clinical trials have studied diabetes prevention with a pharmacologic intervention in women with a history of GDM. 51,[56][57][58][59][60] Troglitazone 59 and pioglitazone 60 have been shown to be more effective than placebo in preventing progression to type 2 diabetes but are not recommended for women of reproductive age.…”

Impact of pregnancy on long‐term health: Advances in postpregnancy care—An opportunity to improve long‐term maternal health

“…16 Women with higher body mass index need additional support to continue lactation and health systems should be aware of these requirements. 17,18 In this Supplement we address postpregnancy care as an opportunity to improve maternal long-term health. Lifestyle changes form the cornerstone of any health-promoting intervention and include access to affordable, healthy food-with adaptation of local diets and recipes more appropriate for type 2 diabetes and cardiovascular disease prevention-and the creation of environmental opportunities for physical activity, such as safe parks and open spaces.…”
