“…Nevertheless, it is of note that one study found a gender-related difference in the association between obesity and CKD (9), whereas other reports did not (4,5). Obesity increases renal sodium reabsorption, which results in an elevation of blood pressure (6,10,11) and may explain the observed link between obesity and CKD, as hypertension is one of the most important factors associated with the progression of both diabetic and nondiabetic CKD (7). On the other hand, Kramer et al noted a significant association between obesity and the risk for CKD, defined as ≥ 1+ proteinuria and/ or eGFR < 60 mL/min/1.73 m 2 , in a cohort of hypertensive adults, which was statistically significant after adjustment for blood pressure and diabetes (8).…”

“…4 In most previous studies on obesity, body mass index (BMI) is the most cited index for obesity because it approximates adiposity and fat distribution in adults. 5 In addition, it is simple, inexpensive and has been shown to predict cardiovascular risk and mortality. [6][7][8] BMI has therefore been recommended as an appropriate parameter to define obesity in adults.…”

We aimed at investigating whether the degree of adiposity is related to haemodynamic variables such as systolic blood pressure (SBP), diastolic blood pressure (DBP) and resting heart rate (HR), and to haemodynamic abnormalities such as hypertension and resting tachycardia. A cross-sectional study was carried out among young students in Ebonyi State University, Nigeria. A total of 710 subjects (350 males and 360 females) aged 20-25 years were recruited for the study. Resting blood pressure and HR of subjects were measured and the body mass index (BMI) was calculated from height and weight measurements. The observed prevalences in this study were as follows: overweight, 20% in males and 26% in females; obesity, 8% in males and 6% in females; hypertension, 17% in males and 14% in females; and resting tachycardia, 22% in males and 24% in females. In both genders, BMI showed significant correlations (Po0.001 or Po0.01 or Po0.05) with SBP, DBP and HR after controlling for age and physical activity status, and SBP indicated the strongest association with BMI. Furthermore, the prevalence of hypertension and tachycardia increased with an increase in BMI level, whereas overweight/obese subjects indicated significantly higher risk of hypertension than did the non-overweight/obese controls. The present findings therefore strengthen the previously reported usefulness of BMI in predicting cardiovascular risks and add to our understanding of the early development of obesity-related cardiovascular abnormalities in young adults and the need to prevent obesity early in life and to avoid its unfavourable lifethreatening consequences later in life.

“…However, previous studies have shown different associations between obesity and hypertension in various ethnic groups. 11,12 In recent years, much research has been carried out regarding the prevalence rates of various cardiovascular risk factors in South Africans, but none of these studies has directly compared the characteristics of African women with a control group. Therefore, a controlled study was carefully planned and executed during 2003 and 2004.…”

Should obesity be blamed for the high prevalence rates of hypertension in black South African women?

et al. 2008

Hypertension is highly prevalent in South Africa, resulting in high stroke mortality rates. Since obesity is very common among South African women, it is likely that obesity contributes to the hypertension prevalence. The aims were to determine whether black African women have higher blood pressures (BPs) than Caucasian women, and whether obesity is related to their cardiovascular risk. African (N ¼ 102) and Caucasian (N ¼ 115) women, matched for age and body mass index, were included. Correlations between obesity (total body fat, abdominal obesity and peripheral fat) and cardiovascular risk markers (haemodynamic parameters, lipids, inflammatory markers, prothrombotic factors, adipokines, HOMA-IR (homoeostasis model assessment insulin resistance)) were compared between the ethnic groups (adjusted for age, smoking, alcohol and physical activity). Comparisons between low-and high-BP groups were also made for each ethnic group. Results showed that African women had higher BP (Po0.01) with increased peripheral vascular resistance. Surprisingly, African women showed significantly weaker correlations between obesity measures and cardiovascular risk markers when compared to Caucasian women (specifically systolic BP, arterial resistance, cardiac output, fibrinogen, plasminogen activator inhibitor-1, leptin and resistin). Interestingly, the latter risk markers were also not significantly different between low-and high-BP African groups. African women, however, presented significant correlations of obesity with triglycerides, C-reactive protein and HOMA that were comparable to the Caucasian women. Although urban African women have higher BP than Caucasians, their obesity levels are weakly related to traditional cardiovascular risk factors compared to Caucasian women. The results, however, suggest a link with the development of insulin resistance.
