Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two one-hour face to face participant education and health counselling sessions will be provided by the Cardiovascular nurse/research nurse to include: Diet and exercise to optimise cardiovascular risk factors in women who have been diagnosed with pre-eclampsia and gestational hypertension during pregnancy.
Use of educational materials from The Australian heart foundation on management of hypertension and cholesterol. Health eating diet literature/heart smart.
Review of Cardiovascular risk factors including blood pressure and Cholesterol levels and treating as per current best practice.
The sessions are face to face one on one sessions in the obstetric outpatients dept. The first session is at Visit 1 which is 3 months post-delivery. The second session at visit 2 is 9 months later when the baby is 12 months old.
Topics to be covered include diet review. Using a MEDAS questionnaire. Looking at quantities of red & white meat consumption, Nuts, tomatoes, olive oil. fruits and vegetables, sweetened beverages, pulses and fish, and fast food on a daily and weekly basis.
Weight review, BMI salt intake and processed foods will also be reviewed aiming for long tern weight control.
Two visits over a nine-month period as required one 3 months post-delivery of the baby and 9 months later.
Activity and gentle exercise including moderate and vigorous will be discussed. Advice will be provided on the importance of keeping active. Aiming for participates to be a active as possible. Aiming for 150 minutes of moderate activity weekly which can be incorporated into their daily routine for example brisk walking- pushing the pram/buggy as well as home exercises. Pilates, dancing and cycling.
The cardiovascular nurse specialist will provide support through the study via email, zoom and phone contact on an individual basis. Providing encouragement throughout the study and to try and maintain adherence. The outcomes will be self-reported by participants.

Statistical methods / analysis
Binary and categorical data will be summarized using counts and percentages. Continuous data will be summarized using means and standard deviations, or medians and interquartile ranges (the difference between the 25th and 75th percentiles) if data are found to be skewed. The primary endpoint of change in MEDAS score between 3 and 9 months will be analysed using linear mixed models (Twisk, 2019)16, also employed by Goni et al (2020)13. Under specified conditions, this technique is comparable to a paired samples t-test, employed by Roset-Salla et al (2015)14, but is more flexible and does not require complete data across timepoints.
Analysis of secondary endpoint will employ regression methods appropriate to the type of outcome variable, such as binary logistic regression for binary outcomes, Poisson or negative binomial regression for counts, or median quantile or robust regression if the outcome variable is found to be skewed. All regressions will take possible clustering of observations due to repeated measurements across time, into account.
All statistical analysis will be conducted by, or under the direct supervision of Epworth HealthCare biostatistician A/Prof Dean McKenzie using a standard statistical package such as Stata 18 (Stata Corporation, College Station, Texas, 2023) or higher. Alpha or level of statistical significance will be set at 0.05, 2 tailed. 95% confidence intervals will be reported wherever possible. No interim analysis is planned.

Summary
Brief summary
A diagnosis of pre-eclampsia or gestational hypertension have long-term implications for women's health, with an associated increase in lifetime risk of ischaemic heart disease, stroke, and heart failure.
Research suggests earlier cardiovascular risk assessment for women with a history of hypertensive pregnancy disorders would likely benefit from establishing care with a cardiologist before the age of 45 to optimise modifiable risk factors and initiate primary prevention strategies to reduce cardiovascular disease.
Behavioural science studies have also shown that positive behavioural changes are more likely when individuals are already undergoing significant life changes.
This study aims to review if early intervention of diet and lifestyle counselling and cardiovascular assessment. help improve cardiovascular outcomes in women post delivery of their baby. Through two post natal cardiovascular follow up visits one at 3 months and one at 9 months post delivery and if necessary a review with a cardiologist.
