Abstract:
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 Yaounde´ . Controls
were mothers of children who sought pediatric care at the Gyneco-obstetric hospital of
Yaounde´ , 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.
