Background: Hypertension is one of the major factors for high mortality of adults in Africa. However, complications occur at lower values than those previously classified as hypertension. Thus, prehypertension is considered as a new category of hypertension and a major risk factor for developing clinical hypertension relative to those with normotension, it has been linked with increased future risk of hypertension as well as cardiovascular diseases.Objectives: The objective of this review was to determine prevalence of prehypertension and describe the associated factors of prehypertension in Africa during the past 10 years. Methods:We did a systematic review using the databases PubMed/Medline, and search engine google scholar. We selected sources of publications and conducted an analysis of articles. Keywords in English were: prehypertension, high normal blood pressure, high blood pressure, elevated blood pressure, Africa. Keywords in french were: préhypertension artérielle, préhypertension, pression artérielle normale haute, pression artérielle normale, Afrique.Mesh terms were: Prehypertension, Africa.Results: Twenty-seven articles were selected. Prevalence of prehypertension ranged from 2.5% to 34% in children and adolescents. In adults, prevalence varied from 32.9% to 56.8%. Several factors were associated with prehypertension in Africa. These factors included: age; sex; lifestyle such as smoking, alcohol consumption, low physical activity, overweight and obesity. There were also cardiometabolic factors and few others factors which were associated with prehypertension. Conclusion:This review allowed us to observe that the prevalence of prehypertension was variable according to age of the population and prehypertension is associated with several factors.

Aim: This study assessed selected correlates of overweight and obesity among women in a sub-urban population of Abidjan, Côte d’Ivoire. Methods: A cross-sectional study was conducted during April-May, 2014 in Abobo-Anonkoi 3, a peri-urban city of Abidjan in Côte d’Ivoire. Women of 18 years and older healthy in appearance were randomly recruited from households. Overweight and obesity were measured by BMI respectively greater or equal to 25 and 30 kg/m2. Abdominal obesity was defined by waist to hip ratio greater or equal to 0.80. The level of physical activity was evaluated by the IPAQ questionnaire and the blood pressure according to the criteria of the JNC7 report. A regression analysis of the associated factors with overweight and obesity (age, marital status, level of study, level of physical activity, blood pressure, and socioeconomic status) was carried out. Results: We visited 486 households in which 398 women were approached and 327 agreed to participate in the survey. The average age was 35.25 ± 12.4 years. The prevalence of overweight was 27.2% and that of obesity was 19.6%; 72.2%of women had abdominal obesity. The prevalence of abdominal obesity was 90.6% among obese people. Age (p=0.006), marital status (p=0.002) and blood pressure (p=0.004) were significantly associated with obesity. With regard to abdominal obesity, there was a significant association of educational level in addition to the above factors. Conclusion: Overweight and obesity are a reality in this population of Côte d’Ivoire and about one in five people are affected by the scourge of obesity.
