Waist circumference (WC), a surrogate indicator of abdominal fat mass, is used to measure central obesity associated with increased risk of hypertension, insulin resistance and type 2 DM, whereas body mass index (BMI) is traditionally used to measure somatic obesity. This study aimed to identify the WC and BMI cut-off points to predict the metabolic risk factors for MS and to determine which is a better predictor.\u003Cbr>METHODS This was a cross-sectional study conducted over a period of six months. The study involved 355 subjects aged 13–91 years. Youden’s index was used to identify the optimal cut-off points.\u003Cbr>RESULTS The optimal cut-off point of WC to predict individual metabolic risk in females was 84.5–91.0 cm. The BMI cut-off point to predict hypertension and raised fasting blood sugar was 23.7 kg/m2 , and that for low level high-density lipoprotein cholesterol was 22.9 kg/m2. For males, the corresponding cut-off points were 86.5–91.0 cm for WC and 20.75–25.5 kg/m2 for BMI, with corresponding sensitivities and specificities. Area under the curve and the odds of developing individual and ≥ 2 metabolic risk factors for MS were higher for WC than for BMI.\u003Cbr>CONCLUSION WC is a better predictor of metabolic risk factors for developing MS than BMI. Therefore, we propose that metabolic risk factors be screened when WC ≥ 80 cm is found in both genders regardless of BMI. |  |\n| --- | --- |\n| Keywords: BMI, metabolic risk factors, metabolic syndrome, waist circumference Singapore Med J 2012; 53(8): 545–550\u003Cbr>INTRODUCTION\u003Cbr>Obesity is a well-known risk factor for developing diabetes mellitus (DM), hypertension, dyslipidaemia and coronary heart disease (CHD) .(1-3) The Malaysian National Health Morbidity Survey (NHMS) II (1996) and III (2006) reported an increasing prevalence of obesity from 4.4% to 14.0% and overweight from 16.6% to 29.1% among Malaysians. 29.7% of males were reported to be overweight and 10.0% obese. Women were found to have a higher prevalence of obesity (17.4%) but a slightly lower prevalence of overweight (28.6%) .(4) The NHMS reports were based on body mass index (BMI), the conventional method for measuring obesity.(5) Although BMI is commonly used to measure somatic obesity, recent findings have reported its conflicting association with cardiovascular and obesity-related health risks.(6,7) Besides, body fat distribution is another important risk factor for obesity-related diseases. Excess abdominal fat (also known as central or upper body fat) is associated with an increased risk of hypertension, insulin resistance and type 2 DM.(1) Waist circumference (WC) is often used as a surrogate indicator of abdominal fat mass, as it correlates with both subcutaneous and intra-abdominal fat. Several studies have found WC to bean important predictor of DM, CHD and its mortality rate, and clinical tests such as blood pressure, blood glucose and lipoproteins.(1,3,8,9) Cut-off points of WC for health outcomes | Table I.
