BACKGROUND:Positive associations have been found between Hypertensive Disorders of Pregnancy gestational hypertension, preeclampsia and cardiovascular diseases within non-African populations, no data exist from sub-Saharan Africa. We aimed to assess this association in Cameroonian mothers. METHODS:We used a case-control study. Cases were women diagnosed with any arteriosclerotic cardiovascular disease between 2012 and 2017 at two major hospitals of Yaoundé. Controls were mothers of children who sought pediatric care at the Gyneco-obstetric hospital of Yaoundé, with no diagnosis of cardiovascular disease. We abstracted data from patient files to assess cardiovascular disease and used phone-based questionnaires to assess a prior history of Hypertensive Disorders of Pregnancy. We used logistic regression and propensity scores for data analysis. RESULTS:Out of 1228 individuals selected, 173 cases and 339 controls participated in the study. We found no increased risk of cardiovascular diseases for women with a history of Hypertensive Disorders of Pregnancy (OR = 0.83, 95% CI, 0.51 to 1.34). Women with gestational hypertension had 2.33 (95% CI, 0.99 to 5.50) times the risk of women with no history of Hypertensive Disorders of Pregnancy, an inverse association was observed between preeclampsia and cardiovascular diseases (OR = 0.28, 95% CI, 0.10 to 0.72). CONCLUSIONS:Cameroonian women with a history of gestational hypertension may have a higher risk of cardiovascular diseases. However, population-based studies with more accurate data on the exposure are needed.
