Prévalence de la Pression Artérielle Élevée et Les Facteurs Associés dans les Départements du Borgou et de l’Alibori au Bénin en 2014

Abstract

Background:High blood pressure (HBP) is one of the risk factors in the occurrence of cardiovascular disease (CVD). The objective of this study was to investigate the prevalence of high blood pressure and its risk factors in the Borgou and Alibori Departments in Benin. Methods: This was a descriptive cross-sectional study and analytical held for three months (July 1st to September 30th, 2014) and identified volunteers at least 15 years. The factors were investigated in subjects using a questionnaire providing clinical and behavioral data. The data were analyzed in Epi-info and Khi2 test was used to compare proportions with a statistically significant difference for p<0.05. Results: A total of 1270 subjects were enrolled in the two departments. The mean age of subjects was 42.55 ± 14.6 years. The sex ratio was 0.95. The prevalence of subjects with HBP was 31.10%. The high blood pressure was significantly associated with a history of, diabetes (p = 0.005), with lower limb edema (p = 0.008), the body overload (p = 0.0000), smoking ( p = 0.002), the overuse and misuse of taking infusion (p = 0.03), proteinuria (p = 0.03) and haematuria (p = 0.01). Conclusion:The prevalence ofhigh blood pressure is higher in Borgou and Alibori Departments in Benin and the risk factors are important. Better prevention of risk factors contribute to reduce morbidity and mortality due to cardiovascular disease.
