Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention phase will run for 3-months. Once enrolled in the study, participants will be randomly allocated into 2 groups: 1) Be Healthe for your Heart lifestyle eHealth intervention; 2) control group. The requirements for each group are as follows:

Be Healthe for your Heart (Group 1):
-Participants will be provided with access to online resources developed by the program related to healthy eating, physical activity, weight management and stress management via the Be Healthe for your Heart webpage for 3-months. Participants will can access the website as often as they choose but will be encouraged to log-in once per week.
-Participants will receive weekly newsletter emails which will summarise the information given by the program resources related to a specific health behaviour topic.
-Lifestyle recommendations will be consistent with the National Heart Foundation’s Eating for Heart Health Position Statement and Australia’s Physical Activity and Sedentary Behaviour Guidelines for Adults (18-64 years) and Clinical Practice Guidelines for the Management of Overweight and Obesity in Adults, Adolescents and Children in Australia.
-Participants will be asked to complete an initial 'screening tool' to evaluate their current eating behaviours, physical activity levels, body weight and stress. They will receive individualised automated (generated by the website) feedback based their responses to the screening tool questions. The feedback provided will be based on a scoring system that compares current health behaviours to program recommendations.
-The participants will be able select pre-specified goals for the duration of the study related to healthy eating, physical activity, stress management and weight management on the program website.
-Participants will be able to monitor their progress towards their health behaviour goals and will be provided with automated feedback on their progress throughout the 3-months.
-The study will also objectively measure the participants’ use of the intervention components by recording their website logins, website page visits and number of email newsletters opened.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A researcher that is not a primary investigator of the study will prepare the concealed envelopes and distribute them following the completion of baseline assessments.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation sequence was generated by a computer-based random number algorithm producing individual group allocation in block lengths of six and stratified by time since pre-eclampsia.

Efficacy
Statistical methods / analysis
Data will be measured through the series of objective measures and questionnaires as outlined above. All analyses will be performed using STATA. Data will be presented as mean (SD) or median (IQR) for continuous variables and counts (percentages) for categorical variables. Changes in impact on absolute cardiovascular risk score, cardiovascular risk markers and lifestyle health behaviours will be determined, and differences between groups. Analysis for the efficacy outcomes will be conducted on an intention-to-treat basis (all participants who were randomized to groups and completed baseline assessments) and for completers only (those who provided data at 3-months). The effect of treatment on the efficacy outcomes will be assessed using linear mixed models. The efficacy outcome will be the outcome in the model, time (baseline, 3-months) and treatment group (intervention, control) as predictors, and group × time as an interaction term. The p-value of the interaction term will be used to determine the statistical significance of any difference between treatment groups in the change from baseline. Effect sizes will be calculated using the equation: Cohen’s d = (M1 change score - M2 change score)/SDpooled (change scores).

Summary
Brief summary
The aim of the research is to evaluate the feasibility and preliminary efficacy of a 3-month eHealth intervention for women (aged 18-45 years) with a history of pre-eclampsia (within 4 years of diagnosis). Participants (n=90) will be randomly allocated to the intervention (Be Healthe for your Heart) or the control group. Be Healthe for your Heart supports participants to make changes to key lifestyle behaviours associated with cardiovascular risk, using evidence-based behaviour change techniques (e.g. self-monitoring, goal setting). The Be Healthe for your Heart program resources are tailored to women of childbearing age and delivered via website and email newsletters. Outcomes will be measured at baseline and 3-months, including the Framingham Cardiovascular Disease 30-year risk score, cardiovascular disease risk markers (BMI, waist circumference, blood pressure, biochemical markers), lifestyle risk factors (dietary intake, physical activity, stress levels) and general health and well-being. Intervention acceptability will be evaluated using objective usage data and intervention participant feedback via a process evaluation questionnaire.
