Key result
Postpartum digital lifestyle program achieves ~85% acceptability but fails to improve 3-month CVD risk markers.
Why the study?
To evaluate the acceptability and preliminary efficacy of a web-based cardiovascular disease prevention intervention for women following preeclampsia.
Does the Be Healthe for your Heart web-based behavioral intervention demonstrate acceptability and improve cardiovascular disease risk markers at 3 months compared to standard online heart health information in women with a recent history of preeclampsia?
RCT (n=31)
Single-blind (researchers collecting physical measurements were blinded; participants unblinded)
Randomized block design (block size of 6), stratified by time since last pregnancy complicated by preeclampsia
No
Does the Be Healthe for your Heart web-based behavioral intervention demonstrate acceptability and improve cardiovascular disease risk markers at 3 months compared to standard online heart health information in women with a recent history of preeclampsia?
This pilot RCT demonstrates that a web-based lifestyle intervention is feasible and highly acceptable to postpartum women with a recent history of preeclampsia, supporting the development of larger powered trials to evaluate efficacy on cardiovascular risk reduction.
High acceptability supports feasibility of web-based intervention in postpartum preeclampsia; extends pilot RCT data but leaves efficacy on CVD markers open.
This pilot randomized controlled trial (RCT) aimed to determine the acceptability and preliminary efficacy of a web-based cardiovascular disease (CVD) prevention intervention for women following preeclampsia. Australian women with a recent history (≤4 years post diagnosis) of preeclampsia were randomized into two study arms: (1) Be Healthe for your Heart, a web-based behavioral intervention or; (2) Control, access to the National Heart Foundation website. Assessments were conducted at baseline, and after three months. Intervention acceptability and impact on absolute CVD 30-year risk score, CVD risk markers and health behaviors were assessed. Twenty-four of 31 (77.4%) women completed the three-month assessment. Eleven out of 13 intervention participants (84.6%) agreed/strongly agreed they were satisfied with the program, with a mean score of 4.2 ± 0.9 (maximum of five). There were no significant between or within group differences in absolute CVD risk, CVD risk markers or health behaviors from baseline to three months. Women with a history of preeclampsia were successfully recruited and retained and they reported high levels of acceptability with the Be Healthe for your Heart program. Further research is therefore needed from powered trials to determine the impact of web-based lifestyle interventions on CVD risk in this at-risk group.

Hutchesson et al. (2020) conducted an RCT in History of preeclampsia (n=31). Be Healthe for your Heart web-based lifestyle behavioral intervention vs. Control (access to the National Heart Foundation of Australia website) was evaluated on Intervention acceptability (program satisfaction). The Be Healthe for your Heart web-based intervention achieved high acceptability (84.6% satisfaction; mean score 4.2/5) among women with recent preeclampsia, with no significant between-group differences in 3-month CVD risk markers.
