Prevention & lipidsCohort study
Recording of hypertensive disorders of pregnancy and subsequent cardiovascular risk among New Zealand women
- cohort study
- linked health records from the ProCare Primary Health Organisation and national datasets
Authors' conclusion
HDP is inadequately recorded in primary care in New Zealand. When documented, it identifies women at significantly higher and earlier CVD risk. Improving HDP documentation in primary care may enable earlier and more equitable CVD prevention.
Study context
- Population
- Women in New Zealand: aged 18–64 years for recording comparison; aged 30–64 years without prior cardiovascular disease (CVD) for 5-year incident CVD riskwomen aged 18–64 years
- Participants
- 172,328 women
- Exposure
- association between a history of hypertensive disorders of pregnancy (HDP) and incident CVD over 5 years
