“…Similarly, the reported cut-off points for WC range from 102 cm for American men [8], to 94 cm for Europeans [18], 84.5 cm for Omani Arabs [15], and 85 cm for Tunisians [16] and Japanese [9]. The corresponding figures among women are 88 cm for Americans [8], 80 cm for Europeans [10], Omani Arabs [15] and Asians [9], 85 cm for Tunisians [19] and 90 cm for Japanese [9]. For adults in China, the male WC cut-off points is ≥93 cm and female WC is ≥89 cm [14].…”

A growing number of studies show that different countries and populations require different cut-off points for body mass index (BMI), and waist circumference (WC) leading to obesity. There are no data on optimal cut-off points to metabolic syndrome (MS) among urban residents in Ningxia. Our aim is to determine the appropriate cut-off points for BMI and WC associated with elevated prevalent MS risk among urban residents in Ningxia. A total of 2500 urban residents in Ningxia were examined from May 2008 to March 2009 in a community-based cross-sectional study. Height, body weight, waist circumference and hip circumference were measured to calculate BMI. Fasting blood glucose (FBG), plasma levels of triglyceride (TG), total cholesterol (TC), and highdensity lipoprotein cholesterol (HDL-C) were examined using a blood glucose meter and the chromatographic enzyme method. BMI and WC were measured to assess overweight or obesity. Of these, 301 subjects were chosen according to metabolic syndrome diagnosis standards to form the case group. The control group comprised 301 healthy people without diabetes, hypertension, hyperlipemia, coronary heart disease, cerebrovascular disease, malignant tumors or chronic infections. Logistic regression and receiver-operating characteristic (ROC) curve analyses were used to determine optimal cut-off points for BMI and WC in relation to the area under the curve (AUC), sensitivity and specificity. The optimal cut-off points for male and female respectively were 24.78 kg/m 2 (sensitivity = 0.879, specificity = 0.648) and 24.72 kg/m 2 (sensitivity = 0.804, specificity = 0.767) for BMI, 85.95 cm (sensitivity = 0.701, specificity = 0.641) and 78.25 cm (sensitivity = 0.804, specificity = 0.528) for WC. Urban residents in Ningxia were at high risk of MS, and the cut-off points for BMI and WC were lower than the data currently recommended in Asian population.

“…Because the data on waist circumference were not available, for purposes of this analysis, we used the body mass index (BMI) >30 kg/m 2 as a criterion for classifying patients as obese 28, 29, 30. Other large studies have previously used this substitution and showed that there is a strong linear correlation between waist circumference and BMI value 30, 31, 32

Low HDL, defined as <50 mg/dL among women and <40 mg/dL among men.

Elevated fasting plasma triglycerides ≥150 mg/dL.

Elevated systolic blood pressure ≥130 mm Hg, diastolic value ≥85 mm Hg, or treatment of previously diagnosed hypertension.

Elevated fasting plasma glucose ≥100 mg/dL.

BackgroundWe wanted to explore the association of metabolic syndrome (MetS) versus its individual components with 20‐year all‐cause mortality among patients with stable coronary artery disease.Methods and ResultsThe cohort comprised 12 403 nondiabetic patients with stable coronary artery disease who were enrolled in the Bezafibrate Infarction Prevention Registry between February 1990 and October 1992 and followed up through December 2014. The study cohort was divided into 4 groups: patients without MetS or impaired fasting glucose (IFG), patients with IFG but without MetS, patients with MetS but without IFG, and patients with both MetS and IFG. Kaplan‐Meier survival analysis showed that at 20 years of follow‐up, the rates of all‐cause mortality were the highest among patients with both MetS and IFG (66%). Patients with IFG without MetS experienced a significantly higher mortality rate compared with those with MetS without IFG (61% versus 56%; log‐rank P<0.001). Multivariable Cox proportional hazard analysis showed that the final Cox model demonstrated that the additive effect of MetS (hazard ratio, 1.13; 95% confidence interval, 1.1–1.16; P=0.02) and IFG (hazard ratio, 1.54; 95% confidence interval, 1.46–1.62; P<0.001) on 20 years mortality was nonsignificant (hazard ratio, 1.01; 95% confidence interval, 0.93–1.11; P=0.69). IFG was associated with the most pronounced increase in mortality risk among the individual components (hazard ratio, 1.22; 95% confidence interval, 1.14–1.3; P<0.001).ConclusionsOur findings suggest that IFG alone is a major independent predictor of long‐term mortality among patients with stable coronary artery disease versus other components of the MetS.

“…Currently such cut-off points are derived from studies among European populations and thus may not be applicable to other ethnic groups. Indeed, some studies suggested that Asian populations manifest CVD risk factors at lower levels of BMI and WC than Westerners, owing, in part, to a higher percentage of body fat 5 14 and 90 cm for Japanese 6 . Differences in cut-off points of obesity have a profound effect on prevalence estimates.…”

Background: There are no data on optimal cut-off points to classify obesity among Omani Arabs. The existing cut-off points were obtained from studies of European populations. Objective: To determine gender-specific optimal cut-off points for body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) associated with elevated prevalent cardiovascular disease (CVD) risk among Omani Arabs. Design: A community-based cross-sectional study. Setting: The survey was conducted in the city of Nizwa in Oman in 2001. Subjects and methods: The study contained a probabilistic random sample of 1421 adults aged $20 years. Prevalent CVD risk was defined as the presence of at least two of the following three risk factors: hyperglycaemia, hypertension and dyslipidaemia. Logistic regression and receiver-operating characteristic (ROC) curve analyses were used to determine optimal cut-off points for BMI, WC and WHR in relation to the area under the curve (AUC), sensitivity and specificity. Results: Over 87% of Omanis had at least one CVD risk factor (38% had hyperglycaemia, 19% hypertension and 34.5% had high total cholesterol). All three indices including BMI (AUC 5 0.766), WC (AUC 5 0.772) and WHR (AUC 5 0.767) predicted prevalent CVD risk factors equally well. The optimal cut-off points for men and women respectively were 23.2 and 26.8 kg m 22 for BMI, 80.0 and 84.5 cm for WC, and 0.91 and 0.91 for WHR. Conclusions: To identify Omani subjects of Arab ethnicity at high risk of CVD, cutoff points lower than currently recommended for BMI, WC and WHR are needed for men while higher cut-off points are suggested for women.
