    ABSTRACT: This study is to clarify whether C-reactive protein (CRP) and white blood cell (WBC) count influence insulin homeostasis to the same degree. Serum CRP and peripheral WBC were measured in 739 subjects with normal glucose regulation, 512 with impaired glucose regulation, and 502 newly diagnosed diabetic patients. Levels of insulin resistance (IR) were assessed using the index of homeostasis model (HOMA-IR). Serum CRP and WBC were significantly correlated with HOMA-IR and risk factors of IR. Relative risks of IR for each 1-SD increase of Ln (CRP) and Ln (WBC) were 1.28 (1.10-1.47) and 1.15 (1.01-1.31), respectively after adjustment for age, sex, obesity measurements, and other traditional risk factors. Additional adjustment for WBC slightly attenuated the association between CRP and IR [1.25 (1.08-1.45); P = 0.003] whereas adjustment for CRP substantially attenuated the association of WBC with IR toward null (P = 0.134). Moreover, individuals with both high levels of CRP and WBC were at higher risks of IR than those with high CRP or WBC alone. Both CRP and WBC were significantly associated with risks of IR. CRP might be a more effective biomarker in terms of the association with IR.

    ABSTRACT: To investigate the prevalence of metabolic syndrome in an urbanizing community in Qingpu, a suburb of Shanghai, and to determine which obesity indices, including body mass index, waist circumference (WC), and waist:hip (WHpR), and waist:height (WHtR) ratios, are most closely associated with metabolic syndrome. We conducted a cross-sectional health survey of 1634 individuals (age 15-87 years) in the Jinhulu community located in Qingpu. The National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (NCEP ATP III) criteria were used to define metabolic syndrome, with central obesity defined according to Asia-Pacific (APC) region criteria. The age-standardized prevalence of metabolic syndrome was 3.6% in men and 7.2% in women. Using the criterion of central obesity in the APC, the age-standardized prevalence of metabolic syndrome increased to 8.3% in men and 10.9% in women. Regardless of age, WHtR consistently showed a higher odd ratios (OR) after adjustment for confounding factors of 2.17 (95% confidence interval [CI] 1.12-4.20; P = 0.022) in subjects<52 years of age and 1.92 (95% CI 1.18-3.11; P = 0.008) in those ≥52 years of age. In men, the WHtR was the only significant predictor (OR 2.42; 95% CI 1.15-5.08; P = 0.02) of metabolic syndrome after adjustment, whereas in women WHtR (OR 1.87; 95% CI 1.37-2.85; P =0.0088) was slightly inferior to WHpR and WC. Metabolic syndrome is prevalent in an urbanizing rural area in Qingpu. Of the anthropometric parameters commonly used to identify metabolic syndrome, WHtR may be the best.
