Obesity Index That Better Predict Metabolic Syndrome: Body Mass Index, Waist Circumference, Waist Hip Ratio, or Waist Height Ratio

Abstract

Aim. The aim was to compare body mass index (BMI), waist circumference (WC), waist hip ratio (WHR), and waist height ratio (WHtR) to identify the best predictor of metabolic syndrome (MetS) among Qatari adult population. Methods. A cross-sectional survey from April 2011 to December 2012. Data was collected from 1552 participants followed by blood sampling. MetS was defined according to Third Adult Treatment Panel (ATPIII) and International Diabetes Federation (IDF). Receiver operating characteristics (ROC) curve analysis was performed. Results. Among men, WC followed by WHR and WHtR yielded the highest area under the curve (AUC) (0.78; 95% CI 0.74–0.82 and 0.75; 95% CI 0.71–0.79, resp.). Among women, WC followed by WHtR yielded the highest AUC (0.81; 95% CI 0.78–0.85 & 0.79; 95% CI 0.76–0.83, resp.). Among men, WC at a cut-off 99.5 cm resulted in the highest Youden index with sensitivity 81.6% and 63.9% specificity. Among women, WC at a cut-off 91 cm resulted in the highest Youden index with the corresponding sensitivity and specificity of 86.5% and 64.7%, respectively. BMI had the lowest sensitivity and specificity in both genders. Conclusion. WC at cut-off 99.5 cm in men and 91 cm in women was the best predictor of MetS in Qatar.

Abdominal Obesity and their association with Total Body: Fat Distribution and Composition. Case of Algerian Teenager Male high school students

“…Showed, that our high school students are allocated into two groups, Table 1. The Independent T sample t-test is not significant at P ≤ 0.05 in Age-Wight-height based on body fat classification in the opposite of BFP-BMI-WC, which are significant for the benefit of acceptable class rating (15)(16)(17)(18)(19)(20) [36] in all comparisons.…”

“…Although the new measures clinical support the hip and waist circumference as superior to BMI for predicting adjust body weight in both genders [18]. Confirm by Kyle UG, et al BMI alone cannot provide information about the respective contribution of FFM or fat mass to body weight [19].…”

Fat Type Level: A Simpler Way for Men to Understand Body Shape and Health Risks

“…Body shape and fat distribution are more predictive of future disease than are Weight and Body Mass Index (BMI) [1][2][3][4][5]. An apple-shaped figure, as opposed to a pear-shaped figure, correlates to a body silhouette with a greater Waist-To-Hip ratio and greater health risk for metabolic syndrome, T2DM, heart disease, dyslipidemia, sleep apnea, nonalcoholic liver disease, cancer, and other comorbidities [1,4].…”

In the U.S. two-thirds of the population are either overweight or obese; of these individuals, 80-90% are already diabetic or prediabetic proxy for estimating obesity and its related comorbidities [16].…”

“…Diabesity is a new term recognized within the last few decades to describe how intertwined and metabolically damaging these two diseases are [8,9]. Since 1980, the rates of diabesity in the US have more than doubled; men of normal weight and without diabetes are now in the minority [1]. There is a lack of knowledge in the literature about what evidence-based approaches will help motivate overweight males to start and continue on a weight loss regimen [10].…”
