ObjectiveThe lifelong risks of cardiovascular disease following hypertensive disorders of pregnancy are well described. Awareness of these risks and associated health-seeking behaviours among affected individuals remains unclear. We aimed to assess participants’ knowledge of their cardiovascular disease risk and relevant health-seeking behaviours following a pregnancy affected by preeclampsia or gestational hypertension.MethodsWe undertook a single-site, cross-sectional cohort study. The target population included individuals who birthed at a large tertiary referral centre in Melbourne, Australia, between 2016 and 2020, and were diagnosed with gestational hypertension or pre-eclampsia. Participants completed a survey assessing pregnancy details, medical comorbidities, knowledge of future risks and health-seeking behaviours post-pregnancy.Results1526 individuals met inclusion criteria and 438 (28.6%) completed the survey. Of these, 62.6% (n=237) were unaware of their increased risk of cardiovascular disease following a hypertensive disorder of pregnancy. Participants who reported awareness of their increased risk were more likely to have annual blood pressure monitoring (54.6% vs 38.1%, p<0.01), and at least one assessment of blood cholesterol (p<0.01), blood glucose (p=0.03) and renal function (p=0.01). Participants who were aware were more likely to be taking antihypertensive medication (24.5% vs 6.6%, p<0.01) since pregnancy, compared with those who were unaware. There were no differences between groups in diet, exercise or smoking habits.ConclusionAmong our study cohort, risk awareness was associated with increased health-seeking behaviours. Participants who were aware of their increased risk of cardiovascular disease were more likely to have regular cardiovascular risk factor assessments. They were also more likely to be taking antihypertensive medication.

COVID-19 has resulted in unprecedented changes to maternity care across Australia. This study aims to analyse trends in maternity consultations and the uptake of telehealth in Victoria and New South Wales (NSW) since the first restrictions to reduce COVID-19 transmission were implemented. From March 2020 to April 2021, a higher proportion of antenatal care consultations was delivered via telehealth in Victoria compared to NSW (13.8% vs 7.4%, P < 0.0001). Uptake of telehealth and a shift from in-person care has been a major contributor to maintaining pregnancy care during pandemic restrictions. However, further research is required to understand women's perspectives and health outcomes.

Objectives: The COVID-19 pandemic has been associated with a worsening of perinatal outcomes in many settings due to the combined impacts of maternal COVID-19 disease, disruptions to maternity care, and overloaded health systems. In 2020, Melbourne endured a unique natural experiment where strict lockdown conditions were accompanied by very low COVID-19 case numbers and the maintenance of health service capacity. The aim of this study was to compare stillbirth and preterm birth rates in women who were exposed or unexposed to lockdown restrictions during pregnancy. Design: Retrospective multi-centre cohort study of perinatal outcomes before and during COVID-19 lockdown Setting: Birth outcomes from all 12 public maternity hospitals in metropolitan Melbourne Inclusion criteria: Singleton births without congenital anomalies from 24 weeks gestation. The lockdown-exposed cohort were those women for whom weeks 20- 40 of gestation would have occurred during the lockdown period of 23 March 2020 to 14 March 2021. The control cohort comprised all pregnancies in the corresponding periods one and two years prior to the exposed cohort. Main outcome measures. Odds of stillbirth, preterm birth (PTB), birth weight less than 3rd centile, and iatrogenic PTB for fetal compromise, adjusting for multiple covariates. Results: There were 24,017 births in the exposed and 50,017 births in the control group. There was a significantly higher risk of preterm, but not term, stillbirth in the exposed group compared with the control group (0.26% vs 0.18%, aOR 1.49, 95%CI 1.08 to 2.05, P = 0.015). There was also a significant reduction in preterm birth < 37 weeks (5.93% vs 6.23%, aOR 0.93, 95%CI 0.87 to 0.99, P=0.03), largely mediated by a reduction in iatrogenic PTB for live births (3.01% vs 3.27%, aOR 0.89, 95%CI 0.81 to 0.98, P = 0.015), including iatrogenic PTB for suspected fetal compromise (1.25% vs 1.51%, aOR 0.79, 95%CI 0.69 to 0.91, P= 0.001). There was no significant difference in the spontaneous PTB rate between the exposed and control groups (2.69% vs 2.82%, aOR 0.94, 95%CI 0.86 to 0.1.03, P=0.25). Conclusions: Lockdown restrictions in a high-income setting with low rates of COVID-19 disease were associated with a significant increase in preterm stillbirths and a significant reduction in iatrogenic PTB for suspected fetal compromise.
