Waist circumference has been identified as one of the strongest predictive tool for metabolic syndrome. In general, the optimal BMI and WC thresholds approximated currently used thresholds in men and in white women. Although both body mass index (BMI) and waist circumference (WC) measure the level of overweight and obesity, WC may be more important because of its closer relationship to total body fat. The obesity based on waist circumference risk was divided into tertiles for both waist circumference and BMI. For children, we use BMI-for-age zscores. The prevalence of obesity and its related chronic diseases have been increasing especially in Asian countries. BMI in American adults has increased over the past 18 years. Results For older adults (65-74 and 75+ years old), the BMI threshold for identifying overweight increased to 26.9 and 26.6, respectively, from the. I.World Health . The team looked at the relationships between the four body composition measures and type 2 diabetes risk in 21,072 participants of the Amsterdam-based Healthy Life in an Urban Setting (HELIUS .

Because WC is typically not assessed in clinical practice, this study sought to develop and verify a model to predict WC . WHO Expert Consultation. however, the International Diabetes Federation has suggested . Health researchers have suggested new body mass index (BMI) thresholds for defining overweight and obese individuals in ethnic communities. Ardern CI, Janssen I, Ross R, Katzmarzyk PT. Recent studies reported associations between DNA methylation and obesity, mostly in non-Asian populations. Most individuals were categorized in the same status, whether using the BMI or the WHtR. Among men, a waist circumference of 102 cm equated to 79, 88, and 88 cm for South Asian, black, and Chinese participants, respectively. Based on our findings, the . Previous studies for defining optimal WC cut-off points included high-income and urban settings, and did not cover low-income, rural settings, especially for ethnic minorities. WWI was calculated as waist circumference (cm) divided by the square root of weight (kg).

Objectives The objectives of this study were to determine whether the cross-sectional associations between anthropometric obesity measures, body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR), and calculated 10-year cardiovascular disease (CVD) risk using the Framingham and general CVD risk score models, are the same for women of Australian, UK and Ireland, North . Ashwell, M. Obesity 22 waits Clinical guidelines on the identification, evaluation, and treatment of overweight and obesity in adults: the evidence report. Using WC over BMI and other markers of adiposity emphasised the important role of central obesity Despite a strong association between waist circumference and BMI at the population level, emerging evidence suggests that, across populations, waist circumference might be increasing beyond what is expected according to . In the whole sample at baseline, 47.1% were underweight,. The optimal waist circumference cut-off point was determined through receiver operating characteristics . The sensitivities at the optimal thresholds ranged from 63.5 to 68.5% for BMI and 68.4 to 71.0% for WC and the specificities ranged from 64.2 to 68.8% for BMI and from 68.5 to 71.0% for WC, respectively. We performed an epigenome-wide association study (EWAS) on general . Age-adjusted ORs and 95% CIs for prevalent type 2 diabetes associated with a 0.5-SD increment in each anthropometric measure: BMI, waist circumference (Waist), and WHR (Waist:Hip).

BMI is a simple and widely used clinical measure; however, BMI may not be a reliable indicator of health risk across all racial and ethnic groups (6,8,9). The waist circumference (WC) thresholds that predicts IR in African men and women have not been established, but investigations recently conducted in Africa using indirect measures of IR suggest IR is predicted by . It is therefore a more accurate predictor of obesity classification waist circumference and bmi risk, type 2 diabetes in women and metabolic syndrome. Weight that is higher than what is considered as a healthy weight for a given height is described as overweight or obese. For example, one American Heart Association study found that BMI might not work well to indicate obesity or heart disease for Asians, and may not be the best stand-alone health readers for Blacks, Hispanics, or Specific Islanders, either 5. 3.Body composition. Assessing body mass index and waist circumference thresholds for intervening to prevent ill health and premature death among adults from black, Asian and other minority ethnic groups in the UK 1 Introduction In July 2011, NICE received a referral from the Department of Health on assessing Specifically, waist circumference was measured to the nearest 0.1 cm with a measuring tape placed horizontally around the narrowest part of the torso over undergarments or light clothing at the end of a normal exhalation. In general, the optimal BMI and WC thresholds approximated currently used thresholds in men and in white women. Objectives This study examines the gender effect on the associations between body mass index (BMI), waist circumference (WC), and waist circumference to height ratio (WHtR) with hemoglobin A1c (HbA1c) when Asian-specific cutoffs are applied among Asians living in the USA. Development of health-related waist circumference thresholds within BMI categories. This study determined BMI-, sex- and race-specific WC thresholds.
Body mass index and waist circumference cutoffs to define obesity in indigenous New Zealanders 1 - 3 more. Using WC over BMI and other markers of adiposity emphasised the important role of central obesity WHtR was calculated as waist circumference (cm)/height(cm). Ashwell, M., P. Gunn, and S. Gibson, Waist-to-height ratio . The WC cut-off of 35 in. Central or abdominal obesity, measured as waist circumference (WC), is one of 5 risk factors constituting a diagnosis of metabolic syndrome.1 WC is found to explain obesity-related health risks, 2 and for a given body mass index (BMI), an increase of WC by 5 cm has been associated with an increased risk of death of 17% for men and 13% for women.3. Of note, BMI-specific waist circumference thresholds have been developed in African American and white men and women 112. Body mass index (BMI) and waist-to-hip ratio (WHR) were indica-tors of body fat used in the WHO criteria, [2] while waist circumference (WC) has been rec-ommended as a surrogate for abnormal fat distribution in more recent MS criteria [1]. Increases in weight over time were more harmful in Asians than in the other ethnic groups: For every 11 pounds Asians gained during adulthood, they had an 84 percent increase in their risk of type 2 diabetes; Hispanics, blacks, and whites who gained weight also had higher diabetes risks, but again, to a much lesser degree than Asians. Obes Res 2004;12:1094 . Regardless of your height or BMI, you should try to lose weight if your waist is: 94cm (37ins) or more for men. These cut points were derived primarily in European populations to correspond to risk thresholds for a wide range of chronic diseases and mortality. However, BMI and alternative measures of fat mass have been shown to be highly correlated; furthermore the obesity paradox has also been demonstrated in HF populations using both waist circumference and percent body fat. Results are shown separately by sex and ethnic group (Asian and white). An adult non-pregnant woman whose waist circumference is equal to or greater than 35 inches (88 cm) *Threshold criteria for BMI and waist circumference are generally lower for Asian populations. the IDF recommends the age- and sex-specific 90th per-centile as a cut-off value for waist circumference (WC) in adolescents 10-15 years of age and ethnic-specific WC cut-off value for those 16-18 years of age.13 In previous studies, the threshold percentiles for WC regarding the clustering of cardio-metabolic risk factors WHO Expert Consultation.

Prospective studies using representative populations are required to firmly establish ethnicity-specific and BMI category-specific waist circumference threshold values that distinguish adults at increased health risk. Measuring adults. value of 95 cm, rather than the 102 cm currently used is needed. Chris Ardern. Objectives The objectives of this study were to determine whether the cross-sectional associations between anthropometric obesity measures, body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR), and calculated 10-year cardiovascular disease (CVD) risk using the Framingham and general CVD risk score models, are the same for women of Australian, UK and Ireland, North . Both waist circumference and BMI have sex and ethnic specific cut-offs, which complicates their practical use. If your BMI is 18.5 to 24.9, it falls within the normal or Healthy Weight range.

The sensitivities at the optimal thresholds ranged from 63.5 to 68.5% for BMI and 68.4 to 71.0% for WC and the specificities ranged from 64.2 to 68.8% for BMI and from 68.5 to 71.0% for WC, respectively. 3.4.1 Ethnic groups for which waist circumference or waist-hip . ISSN: 1479-1064; Journal h-index: 22; Journal CiteScore: 7.78 ; Journal Impact Factor: 4.76 ; Average acceptance to publication time (5-7 days) Waist measurement is a measurement which indicates the need for weight management and reflects coronary risk related to both overweight and a central fat distribution. The thresholds are: underweight for BMI 18.5 kg/m 2; normal if BMI 18.5 kg/m 2 and 25 kg/m 2; and overweight or obesity for BMI 25 kg/m 2. The baseline characteristics of 27,026 oldest old in different BMI groups categorized by guidelines are presented in Supplementary Table 1. PLoS ONE 2012; 7: e48883. This study determines the optimal cut-off point of waist circumference for metabolic syndrome among low-income earning South African black population, in Eastern Cape, South Africa.
