Evaluation of waist-to-height ratio to predict 5 year cardiometabolic risk in sub-Saharan African adults

Abstract

The WHtR threshold of >0.5 appears to be more consistently supported and may provide a better predictor of future cardiometabolic risk in sub-Saharan Africa.

Use of the waist‐to‐height ratio to predict cardiovascular risk in patients with diabetes: Results from the ADVANCE‐ON study

“…WHtR has been found previously to align well across different age groups, genders and ethnicities, which is in agreement with our findings. A meta‐analysis of elderly individuals showed that WHtR was a better predictor of cardiovascular risk in younger elderly individuals compared to older elderly individuals .…”

“…Models were adjusted for age, sex, current smoking status, Asian region, randomized blood pressure-lowering intervention and randomized glucose control intervention. Values were trimmed at less than 1st percentile and greater than 99th percentile of each obesity index WHtR has been found previously to align well across different age groups, genders and ethnicities, 12,27,28 which is in agreement with our findings. A meta-analysis of elderly individuals showed that WHtR was a better predictor of cardiovascular risk in younger elderly individuals compared to older elderly individuals.…”

“…In the general population, WHtR has been found to better predict CVD compared to WC and BMI, while BMI has been shown repeatedly to perform worse than WHtR and WC . A suitable WHtR cut‐point for increased cardiometabolic risk in the general population approximates 0.5 in several previous studies . In a study of Han and Uygur Chinese people with diabetes, the suggested cut‐point for increased cardio‐metabolic risk was 0.6 for men and women in both ethnic groups .…”

The association of clot lysis time with total obesity is partly independent from the association of PAI-1 with central obesity in African adults

“…b African specific WC cut-off point for central obesity [25]. c African specific [27] cut-off point for central obesity.…”

“…African specific cut-offs were used to indicate abdominal obesity [26]. An additional relatively new indicator of central obesity; waist: height ratio (WHtR) was calculated with the formula WHtR = WC (cm)/height (cm) and used in conjunction with WC to indicate central obesity also using African specific cut-offs [27]. A Harpenden caliper (Baty International West Sussex, UK) was used to measure skinfolds (triceps, chest, abdominal, thigh and supra iliac).…”
