Aims The aim was to compare waist-to-thigh ratio (WTR), waist-to-height ratio (WHtR),waist-to-hip ratio (WHR), waist circumference (WC) and body mass index (BMI) as predictors of hyperglycemia (fasting plasma glucose≥5.6 mmol/ L) among Beijing adult brainworkers.Methods A cluster sampling was conducted in Beijing ShiJitan Hospital in August 2010.1280 adult brainworkers were examined on height, weight, WC, hip circumference, thigh circumference, and fasting glucose and so on.Results ①The rate of hyperglycemia was 40.16%, increasing along with age.The level of WC、 BMI、 WHtR、 WHR、 WTR、 SBP、 DBP、 TC、 TG、 UA in hyperglycemia group was significantly higher than that of normal glucose group (P< 0.001), but the level of HDL-C is lower than normal glucose group.Meanwhile, the prevalence rate of fat liver in hyperglycemia group was significantly higher than that of normal glucose group.② Receiver operating characteristic curve analysis was used to measure the predictive hyperglycemia performance of each anthropometric measurement based on the area under the curve (AUC).AUC of WTR (0.716) was larger than that of WHtR (0.690) (P < 0.001), WHR(0.682) (P < 0.001), WC (0.682) (P <0.001), and BMI (0.665) (P < 0.001) for hyperglycemia.In men, AUC of WTR (0.648) was larger than that of WHtR (0.611) (P < 0.001), WHR(0.614) (P < 0.001), WC (0.598) (P<0.001), and BMI (0.587) (P <0.001) for hyperglycemia.In women, the AUC of WTR(0.754)was smaller than that of WHtR (0.771) (P < 0.001), and WC(0.761) (P < 0.001), but larger than that of BMI(0.738) (P<0.001) and WHR (0.723) (P<0.001)for hyperglycemia.Stratified by age, in women who age ≥35 years, the AUC of WTR(0.725) was larger than that of WHtR(0.716) (p<0.001)、 WC(0.705) (P<0.001)、 WHR) 0.676))(P<0.001) and BMI(0.665)(P<0.001).③After adjustment for age and gender, logistic regression analyses showed that WTR have the strongest association with hyperglycemia (OR, 1.70;95% CI, 1.37 -2.11; per 1 SD increment).Conclusions Hyperglycemia is a serious health problem in adult brainworkers.WTR performed better than other four indices in all men and in women age≥35 for the association with hyperglycemia.
