ABSTRACT: Introduction: Hypertension disorders of pregnancy are one of the leading causes of maternal and fetal deaths. We aimed to estimate the prevalence of hypertension among pregnant women having participated in the STEPS survey in Benin in 2015. Methods: This was a database analysis. STEPS survey included consenting adults aged 18 to 69 years, living in Benin for at least 6 months prior to the survey. The participants were selected in households by a three-stage random sampling technique. The World Health Organization (WHO) STEPS instrument was used for data collection. After an individual interview with the participant at home, blood pressure was measured according to WHO recommendations. Pregnant women database was extracted for analysis. A multivariable logistic regression was done for associated factors identification. Results: A total of 2800 women (out of 5127 people) participated in the STEPS study of which 240 declared to be pregnant. The mean age was 28.9 ± 6.8 years. The prevalence of hypertension was 13.3%. Severe hypertension represented 2.9%. Hypertension during pregnancy was associated with primary school education level (compared to none, adjusted OR = 0.3, 95% CI [0.1 - 0.9], p = 0.042). No significant association was found with behavioral factors. Conclusion: The prevalence of hypertension during pregnancy is high in Benin. In-depth studies and targeted interventions for prevention should be implemented.
