Detection of Prediabetes and Undiagnosed Type 2 Diabetes: A Large Population-Based Study

Severity of coronary artery disease and retinal microvascular signs in patients with diagnosed versus undiagnosed diabetes: cross-sectional study

“…The prevalence of undiagnosed diabetes in the AHES is similar to prevalence rates reported in several other population studies (13)(14)(15). Table 1 shows the study characteristics of participants with undiagnosed diabetes and with previously diagnosed diabetes.…”

Waist‐to‐height ratio is the best indicator for undiagnosed Type 2 diabetes

“…Overall overweight and central obesity were defined as BMI ≥ 24 kg/m 2 , and waist circumference ≥ 85 cm for men or waist circumference ≥ 80 cm for women, respectively, according to the recommended criteria for the Chinese population . Waist–hip ratio was calculated as waist circumference (in cm) divided by hip circumference (in cm), and also dichotomized (< 0.85 vs. ≥ 0.85) based on previous reports and the distribution of waist–hip ratio among participants with impaired fasting glucose and without both impaired fasting glucose and Type 2 diabetes. Waist‐to‐height ratio was calculated as waist circumference (cm) divided by height (cm), and dichotomized (< 0.5 vs. ≥ 0.5) according to the recommended criteria .…”

“…Waist‐to‐height ratio was calculated as waist circumference (cm) divided by height (cm), and dichotomized (< 0.5 vs. ≥ 0.5) according to the recommended criteria . Fasting capillary blood samples were taken from all participants and capillary plasma glucose was measured by the OneTouch ® UITRA 2 meter (Life Scan Inc., Milpitas, CA, USA) for screening . After the screening test, subjects with capillary plasma glucose level ≥ 5.4 mmol/l underwent a fasting plasma glucose test and a postprandial 2‐h plasma glucose test after eating a steamed bread meal containing carbohydrates equivalent to 75 g of glucose.…”

“…Waist-hip ratio was calculated as waist circumference (in cm) divided by hip circumference (in cm), and also dichotomized (< 0.85 vs. ! 0.85) based on previous reports [16,17,19] and the distribution of waist-hip ratio among participants with impaired fasting glucose and without both impaired fasting glucose and Type 2 diabetes. Waist-to-height ratio was calculated as waist circumference (cm) divided by height (cm), and dichotomized (< 0.5 vs. !…”

Relation of socio‐economic status to impaired fasting glucose and Type 2 diabetes: findings based on a large population‐based cross‐sectional study in Tianjin, China

“…In addition, height, weight and blood pressure were measured by trained examiners, as described in detail elsewhere [14]. In addition, height, weight and blood pressure were measured by trained examiners, as described in detail elsewhere [14].…”
