“…Hypertension prevalence rates in some surveys of urban populations in other parts of Africa include 7.4% for men and 10.2% for women in Dakar, Senegal, 7 13.6% and 6.8% in Kinshasa, Zaire, 14 and 9.2% and 12.9% in the Cape Peninsula, South Africa. 15 However, an earlier report had shown a hypertension prevalence of 25% (23% in men, 27% in women) in the urban Zulu and 9.4% in the rural Zulu in South Africa, 16 using the 160/95 mm Hg cut-off point. The high prevalence in the urban Zulu is comparable to figures obtained in black Americans and does not appear to have been found in other black Africans.…”

To provide an update on blood pressure (BP) levels and hypertension correlates in urban workers in Ibadan, Nigeria, we administered a questionnaire to, and measured the BP in, 608 men and 309 women, age range 18-64 years. Systolic BP (SBP) rose in men and women after the age of 25, but the rise in diastolic BP (DBP) started earlier dropping in women only after the age of 44. SBP and DBP were higher in men than women (P Ͻ 0.001). The prevalence of hypertension was 9.3% in the population, being 10.4% in men and 7.1% in women; ageadjusted rates were 9.8% and 8.0% respectively. The prevalence of hypertension increased with age in both genders. Body mass index was correlated to SBP (r = 0.142, P = 0.022) and DBP (r = 0.149, P = 0.032) in men,

“…41 Urbanized Zulus had a high prevalence of hypertension (25%) compared with only 2-8% in rural areas. 42 The greater mean WHR of the rural students and the greater percentage having a WHR ≥ 0.80 should be interpreted cautiously. It is possible that many rural women still have not adopted the 'Western' concept of beauty, which encompasses a very slim (waist) figure.…”

The objective of this study was to examine dietary intake, weight status and nutrition knowledge of young black South African women in order to identify urban-rural differences. A group of 115 black female students attending a first-year pre-registration program at the University of the North participated in the study. A quantified food frequency questionnaire was used to gather data on each student's diet prior to entering the university. Height, weight, waist and hip measurements were taken, and body mass index (BMI) and waist-tohip ratio (WHR) were calculated for each participant. Each student also completed a nutrition knowledge test (NKT). Mean dietary intakes were generally comparable to the recommended dietary allowances (RDA), with the exception of calcium, zinc and iron, which were lower. Urban women consumed significantly more sugar (65.8 vs 52.2 g) and confectionery (290.4 vs 183.7 g), and significantly less legumes (6.3 vs 18.9 g), than did rural women. The prevalence of overweight (BM1 >= 25) was high in urban (22.7%) and rural (22.9%) women and WHR was significantly greater (P = 0.0003) in rural women (0.76) compared with urban ones (0.73). Nutrition knowledge test scores were poor (mean = 40.7%) and no urban-rural differences were found. There was a positive correlation between NKT and energy, protein, carbohydrate, fibre, calcium, zinc, thiamin, niacin, and folate intakes.

Eur J Clin Invest 2012; 42 (11): 1221–1226 Abstract Background The hallmark of vascular inflammation is the recruitment of circulating leucocytes, primarily monocytes, macrophages and T lymphocytes, into the vascular wall; however, the link between monocyte/macrophage activation and hypertension has not been established as yet. In this study, we determined how sCD163, a monocyte/macrophage soluble scavenger receptor and immunomodulator, relates to arterial blood pressure (BP) in hypertensive Saudi individuals. Materials and methods A total of 90 (30 non‐hypertensive obese, 30 hypertensive obese and 30 lean normotensive controls) adult Saudi subjects, aged 40–60 years, participated in this cross‐sectional study. Serum fasting blood glucose, triglycerides, total cholesterol, HDL‐cholesterol (HDL‐C), LDL‐cholesterol (LDL‐C), leptin, adiponectin, resistin, insulin, tumour necrosis factor‐alpha (TNF‐α), PAI‐1, angiotensin II, high‐sensitivity C‐reactive protein (hsCRP) and sCD163 were measured in all subjects studied. Results sCD163 concentrations were significantly increased in obese hypertensive patients compared to controls (P = 0·016). Positive correlations between sCD163 and body mass index (BMI) (r = 0·27, P = 0·01), systolic BP (r = 0·25, P = 0·01), diastolic BP (r = 0·33, P = 0·001), LDL‐C (r = 0·21, P = 0·04), TNF‐α (r = 0·23, P = 0·02) and hsCRP (r = 0·33, P = 0·008) were observed. Positive correlations between sCD163 and diastolic BP (r = 0·23, P = 0·04) and LDL‐C (r = 0·22, P = 0·03) remained significant after controlling for BMI. Conclusions Taken together, these data demonstrate that the monocyte/macrophage activation‐related sCD163 is positively associated with BMI and increased arterial BP with the elevation in diastolic BP being independent of the BMI.
