Prevalence, Associate Health Conditions and Evolution of Chronic Hypertension Among Pregnant Women in Abidjan's Neighborhood.

Objective: In Côte d'Ivoire, prevalence of hypertension was 39.9% in 2017. This study aimed to determine the prevalence, associate health conditions and evolution of chronic hypertension among pregnant women in Abidjan's neighborhood. Methods: This was a prospective multicenter cohort study. Bivariate and multivariate analysis was performed. Results: Prevalence of chronic hypertension was 8.6% [6.11-11.09]. Age (p = 0.001; 95% CI: 2.2-14.5); hyperglycemia (p = 0.04; 95% CI: 1.1-33.5); total cholesterol level (p = 0.02; 95% CI: 1.2-7.3); LDL cholesterol level (p = 0.01; 95% CI: 1.2-5.0); left ventricular hypertrophy (p = 0.03; 95% CI: 1.1-6.6) were significantly associated with chronic hypertension. After multivariate analysis, age ≥35 years (OR = 3.9; 95% CI: 1.4-11.8; p = 0.01) was the only variable statistically associated with chronic hypertension. During the follow-up to full-term pregnancy, systolic and diastolic blood pressures were significantly lower than those collected at inclusion. No complication such as preeclampsia was observed. Conclusion: The prevalence of chronic hypertension was relatively high. Women aged 35 and over were most at risk of developing the disease. Blood pressure gradually fell and stabilized in the women. No complication was observed.
