Preferred lifestyle intervention characteristics and behaviour change needs of postpartum women following cardiometabolic pregnancy complications.

Background: Women with cardiometabolic pregnancy complications are at increased risk of future diabetes and heart disease which can be reduced through lifestyle management postpartum.
Objectives: This study aimed to explore preferred intervention characteristics and behaviour change needs of women with or without prior cardiometabolic pregnancy complications for engaging in postpartum lifestyle interventions.
Design: Quantitative cross-sectional study.
Methods: Online survey.
Results: Overall, 473 women were included, 207 (gestational diabetes (n = 105), gestational hypertension (n = 39), preeclampsia (n = 35), preterm birth (n = 65) and small for gestational age (n = 23)) with and 266 without prior cardiometabolic pregnancy complications. Women with and without complications had similar intervention preferences, with delivery ideally by a healthcare professional with expertise in women's health, occurring during maternal child health nurse visits or online, commencing 7 weeks to 3 months post birth, with 15- to 30-min monthly sessions, lasting 1 year and including monitoring of progress and social support. Women with prior complications preferred intervention content on women's health, mental health, exercise, mother's diet and their children's health and needed to know more about how to change behaviour, have more time to do it and feel they want to do it enough to participate. There were significant differences between groups, with more women with prior cardiometabolic pregnancy complications wanting content on women's health (87.9% vs 80.8%, p = 0.037), mother's diet (72.5% vs 60.5%, p = 0.007), preventing diabetes or heart disease (43.5% vs 27.4%, p < 0.001) and exercise after birth (78.3% vs 68.0%, p = 0.014), having someone to monitor their progress (69.6% vs 58.6%, p = 0.014), needing the necessary materials (47.3% vs 37.6%, p = 0.033), triggers to prompt them (44.0% vs 31.6%, p = 0.006) and feeling they want to do it enough (73.4%, 63.2%, p = 0.018).
Conclusion: These unique preferences should be considered in future postpartum lifestyle interventions to enhance engagement, improve health and reduce risk of future cardiometabolic disease in these high-risk women.
