“…Hypertension is a key driver of the cardiovascular disease (CVD) epidemic in Africa, and a major independent risk factor for heart failure, stroke and kidney failure [6,7]. A recent study conducted in Zimbabwe showed that the prevalence of uncontrolled hypertension was still high despite patients being treated with medication [8].…”

AbstractIntroduction: Hypertension is a leading global health problem requiring lifelong treatment. However, adherence to antihypertensive medicines is a problem, higher among developing countries. Consequently, there is a need to determine current adherence rates and their associations among developing countries to plan future initiatives. Methods: Cross-sectional study among adult outpatients with essential hypertension in Tanzania. Pre-designed questionnaires were used to gather information on adherence rates and patient-related beliefs. The main outcome measure was adherence. Results: 180 participants were included, with females making up 65%. High adherence rates in 54% of patients. Patients' belief about their medication and its necessity were higher in the high adherent group and concerns about their medicines and their necessity higher in the low adherent group. Conclusion: Adherence rates were low compared to a suggested level ≥ 80 %.

“…Other potential cause of heart failure like rheumatic heart disease (24) or myocarditis (presumably linked to infectious diseases like streptococcus and HIV infections (26,27) are frequent in SSA settings. However, the uncontrolled blood pressure remains the major factor for left ventricular hypertrophy (LVH) (28) and heart failure (29,30). The same holds for stroke (24,31,32) and renal failure (33)(34)(35).…”

“…1 Hypertension is a major public health concern in the urbanised black population in South Africa. [2][3][4] Adults in the South African North West Province are no exception, and indicated a hypertension rate of 21.8%. 5 Although clinical hypertension occurs less frequently in children than in adults, [6][7][8] ample evidence now supports the concept that the roots of essential hypertension extend back to childhood.…”

Although clinical hypertension occurs less frequently in children than in adults, ample evidence supports the concept that the roots of essential hypertension extend back to childhood. Since little is available in the literature on causal dietary factors of hypertension in children, this study hypothesised that certain dietary factors can be identified as risk markers that might contribute to the aetiology of hypertension in black children. Children aged 10-15 years were randomly selected from 30 schools in the North West Province from 2000 to 2001. These children comprised 321 black males and 373 females from rural to urbanised communities, of which 40 male and 79 female subjects were identified with high-normal to hypertensive blood pressure. Blood pressure was measured with a Finapres apparatus and data were analysed with the Fast Modelflo software program to provide systolic, diastolic and mean blood pressure. A 24-h dietary recall questionnaire and weight and height measurements were taken.In a stepwise regression analysis, the following variables were significantly associated (Pp0.05) with blood pressure parameters of hypertensive males: biotin, folic acid, pantothenic acid, zinc and magnesium. Energy, biotin and vitamin A intakes were significantly associated with blood pressure parameters of hypertensive females. No significant dietary markers were indicated for any of the normotensive groups. Dietary intakes of all of these nutrients were well below the dietary reference intakes. In conclusion, the dietary results coupled with the cardiovascular parameters of this study identified folic acid and biotin as risk markers that could contribute to the aetiology of hypertension in black persons. The low intakes of these nutrients, among others, is a matter of serious concern, as is the increasing tendency towards urbanisation.
