Anthropometric Cutoff Points for Predicting Chronic Diseases in the Mexican National Health Survey 2000

Abstract

[37.3(Ϯ 12.9) years] were assessed for values of body mass index (BMI) and waist circumference (WC) for predicting DM or HT by receiver operating characteristic curve analyses. Likelihood ratios for DM and HT were calculated, and BMIs or WCs for public-health screening were developed. Subanalyses included regional data. Results: Likelihood ratios of DM and HT increased from BMI values of 22 to 24 kg/m 2 in both sexes and with WC values of 75 to 80 cm in men and 70 to 80 cm in women. The best BMI cutoffs for predicting DM were 26.3 to 27.4 kg/m 2 in men and 27.7 to 28.9 kg/m 2 in women, with similar values for HT, i.e., 26.2 to 27.0 kg/m 2 and 27.7 to 28.5 kg/m 2 , for men and women, respectively; WC cutoffs for DM were 93 to 98 cm in men and 94 to 99 cm in women, and cutoffs for HT were 92 to 96 cm and 93 to 96 cm for men and women, respectively. The WC cutoffs had higher sensitivity and specificity than those of BMI. Discussion: The risk for DM and HT starts at lower levels of BMI and WC than those suggested by WHO. WC is a better discriminator than BMI measures for use in public health.

Anthropometric predictors for the risk of chronic disease in non-diabetic, non-hypertensive young Mexican women

“…A similar relationship after stratifying by age has been seen in other studies 49,[51][52][53] which may be because BMI is a less sensitive measure for total body fat as age increases 54 . This finding emphasises the importance of prevention from a young age.…”

“…These cut-off points are very similar to those reported in a national sample of older women in Mexico for the diagnosis of existing diabetes (28.0 kg m 22 ) or hypertension (27.8 kg m 22 ) 49 and are slightly higher than those found in a smaller sample of older hospital workers to diagnose existing diabetes (25.4 kg m 22 ) or hypertension (26.6 kg m 22 ) 26 . In the nationally representative sample of the Mexican population (n 5 26 647 women, mean age 37.3 6 12.9 years, mean BMI 27.6 6 5.6 kg m 22 ) there was a much higher prevalence of hypertension (25.6%) and diabetes (7.2%).…”

Detection of cardio-metabolic risk by BMI and waist circumference among a population of Guatemalan adults

“…*Empirically determined optimal cut-off point for BMI (kg/m 2 ), defined as the value where (Sens1Spec) is maximised. due to different definitions of hypertension and the prediction of diabetes rather than impaired fasting glucose), the Mexican National Health Survey also identified optimal WC cut-off points that were slightly higher for women than men (94-99 cm and 93-98 cm, respectively) (38) . A study of hospital workers in Mexico described optimal cut-off points for WC as 90 cm among men and 85 cm among women (39) .…”

Fatty liver largely explains associations of subclinical hypothyroidism with insulin resistance, metabolic syndrome, and subclinical coronary atherosclerosis

“…Height, weight, and waist circumference were measured and BMI was calculated as weight in kilograms divided by height in meters squared. The MS was defined using the criteria from the American Heart Association/ National Heart, Lung, and Blood Institute scientific statement on the MS (19), except for central obesity that was considered when waist circumference was O90 cm in men and O80 cm in women (20). Diabetes was defined by the American Diabetes Association criteria (21) and was also considered when participants reported glucoselowering treatment or a physician diagnosis of diabetes.…”
