# Prenatal Breastfeeding Counseling Intervention in Women with Pre-Gestational Diabetes Mellitus—A Randomized Controlled Trial

## TL;DR

This study found that targeted breastfeeding counseling near the end of pregnancy for women with pre-gestational diabetes did not change breastfeeding rates but improved their confidence and knowledge.

## Contribution

The study introduces a targeted diabetes-oriented breastfeeding counseling approach and evaluates its impact on knowledge and confidence in this specific population.

## Key findings

- Breastfeeding rates in women with pre-gestational diabetes were similar to those without diabetes.
- End-of-pregnancy counseling improved confidence in breastfeeding knowledge and blood glucose management.
- No significant difference in breastfeeding rates was found between counseling groups.

## Abstract

Background: Data on breastfeeding rates and targeted interventions in women with pre-gestational diabetes mellitus are inconclusive. The aim of the study was to evaluate breastfeeding rates up to one year postpartum and whether targeted counseling towards the end of pregnancy can impact breastfeeding rates and duration. An additional goal was to evaluate whether counseling affected women’s perceptions regarding breastfeeding. Methods: Women with pre-gestational diabetes mellitus were cluster-randomized between 32 and 36 weeks of gestation, either to face-to-face instruction with a certified lactation consultant or to receive written information on breastfeeding. Thirty-eight women without diabetes served as controls and were given written information on breastfeeding. All women filled out a questionnaire regarding intended breastfeeding duration, exclusivity, and perceptions, before intervention and at three, six, and twelve months post-partum. Results: Fifty-two women with pre-gestational diabetes mellitus consented to participate. All completed the questionnaires, 26 in each group. At three, six, and twelve months postpartum, rates of any breastfeeding were around 60%, 50%, and 30%, respectively. Approximately one-third breastfed exclusively in each group at three and six months. No significant difference in breastfeeding rates was noted between face-to-face instruction, written information, and controls. End-of-pregnancy counseling improved confidence in breastfeeding knowledge and confidence in being able to manage blood glucose. Conclusions: Breastfeeding rates in pre-gestational diabetes mellitus were comparable to those of women without diabetes and were unchanged by mode of instruction at the end of pregnancy. However, targeted diabetes-oriented breastfeeding instruction at the end of pregnancy improved knowledge and confidence among women with pre-gestational diabetes mellitus.
