Background
Hypertensive disorders of pregnancy (HDP) are associated with maternal adverse cardiovascular outcomes. However, their association with maternal Dementia and Alzheimer’s disease is not well established with limited and conflicting results to date.
Objective
We sought to evaluate the association between HDP and risk of incidence of Dementia, and Alzheimer’s disease.
Methods
We performed a systematic review and meta-analysis of available literature that enrolled women with HDP and women without HDP groups. PubMed, Embase and ClinicalTrials.gov were systematically searched from inspection till May 2024 without any language restrictions. Adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were pooled using a random-effect model.
Results
A total of 8 studies with 2503538 patients (1,51,905 in women with HDP and 23,51,633 in the women without HDP group) were included. Pooled analysis shows that HDP women were having 37% higher risk of dementia (aHR, 1.37(95%CI: 1.27-1.46), P<0.001, I2=0%) when compared with women without HDP. Further pooled analysis showed that women with HDP were having 28% higher risk of Alzheimer’s disease (aHR, 1.28(95%CI: 1.56), P<0.001, I2=53.98%), and 2-fold higher risk of vascular dementia (aHR, 2.49(95%CI: 1.29-3.68), P<0.001, I2=71.51%) when compared with women without HDP.
Conclusion
Women with HDP were at higher risk of developing Dementia, and Alzheimer's disease in future.
