Objective
To explore the experiences of postnatal women who are obese [body mass index (BMI) ≥ 30 kg/m2] in relation to making behaviour changes and use of behaviour change techniques (BCTs).
Design
Qualitative interview study.
Setting
Greater Manchester, UK.
Population or Sample
Women who were 1 year postnatal aged ≥18 years, who had an uncomplicated singleton pregnancy, and an antenatal booking BMI ≥ 30 kg/m2.
Methods
Eighteen semi‐structured, audio‐recorded interviews were conducted by a research midwife with women who volunteered to be interviewed 1 year after taking part in a pilot randomised controlled trial. The six stages of thematic analysis were followed to understand the qualitative data. The Behavior Change Technique Taxonomy (version 1) was used to label the behaviour change techniques (BCTs) reported by women.
Main outcome measures
Themes derived from 1‐year postnatal interview transcripts.
Results
Two themes were evident: 1. A focused approach to postnatal weight management: women reported making specific changes to their eating and physical activity behaviours, and 2. Need for support: six BCTs were reported as helping women make changes to their eating and physical activity behaviours; three were reported more frequently than others: Self‐monitoring of behaviour (2.3), Prompts/cues (7.1) and Social support (unspecified; 3.1). All of the BCTs required support from others for their delivery; food diaries were the most popular delivery method.
Conclusion
Behaviour change techniques are useful to postnatal women who are obese, and have the potential to improve their physical and mental wellbeing. Midwives and obstetricians should be aware of such techniques, to encourage positive changes.
