Visceral Adiposity and Anthropometric Indicators as Screening Tools of Metabolic Syndrome among Low Income Rural Adults in Xinjiang

Abstract

Most previous studies on metabolic syndrome (MetS) examined urban and high income settings. We thus investigated the prevalence of MetS among a multi-ethnic population living in a low income rural area and explored the use of visceral adiposity and anthropometric indicators to identify men and women with MetS. We recruited 10,029 individuals of nomadic Kazakhs, rural Uyghur and Han residents in Xinjiang, China. MetS was defined by the Joint Interim Statement criteria. The receiver operating characteristic curve (ROC) was used to compare the area under the ROC curve (AUC) of each index. The age-adjusted prevalence of MetS was 21.8%. The visceral adiposity index (VAI), lipid accumulation product (LAP), body adiposity index (BAI) and the waist-to-height ratio (WHtR) were significantly associated with MetS, independent of ethnic, age, and other covariates. The AUC of VAI, LAP and WHtR were all greater than 0.7, and the LAP was the index that most accurately identified MetS status in men (AUC = 0.853) and women (AUC = 0.817), with the optimal cut-offs of 34.7 and 27.3, respectively. In conclusion, the prevalence of MetS in low income rural adults of Xinjiang was high and the LAP was an effective indicator for the screening of MetS.

Indicadores de obesidade: capacidade preditiva para síndrome metabólica em adultos quilombolas

“…This value shows good capacity to identify adult quilombolas who will truly have MetS and consequently a low probability of false-negative results in provisional diagnostic tests replacing the gold standard. These values are similar to 16 or better 12,13,17 than those found in the literature.…”

“…different adult populations have also shown the MetS screening capacity of BF% 16 , BAI [13][14][15] and BMI 12,[14][15][16][17] . However, to our knowledge, this is the first study to evaluate the capacity of the three main general OIs to screen for MetS in the same study of adults.…”

“…Studies have shown variations in the screening capacity of different general OIs for MetS according to population profile [12][13][14][15][16][17] . In addition, studies involving different population groups have identified differences in the predictive capacity of OIs according to ethnic-racial characteristics [18][19][20] .…”

Anthropometric and central obesity indices as predictors of long-term cardiometabolic risk among Saudi young and middle-aged men and women

“…The components of the lipid panel and other anthropometric parameters were used to calculate the central obesity indices, such as the visceral adiposity index and lipid accumulation product. The VAI for males = [WC/(39.68+(1.88 x BMI)] x [TG (mg/dl) /1.03] x [1.31/HDL (mg/dl) ], and the VAI for females = [WC/(36.58+(1.89 x BMI)] x [TG (mg/dl) /0.81] x [1.52/HDL (mg/dl) ] 15. The LAP was calculated as [{WC(cm) − 65} × {TG (mmol) }] for men and [{WC (cm) − 58} × {TG (mmol) }] for women 16…”

Association of total bilirubin and indirect bilirubin content with metabolic syndrome among Kazakhs in Xinjiang

“…Kazakhs in Xinjiang, China are nomadic minorities living primarily in remote mountainous areas. The majority fall into a low economic class and their culture and customs are signi cantly different from those of other ethnic groups [11,12]. A previous study by our research group found the prevalence of MS in Kazakhs to be higher than that in other ethnic groups in Xinjiang and higher than the national average [13].…”
