Table 4 Multivariable logistic regression analysis for the association between lung function and incident type 2 diabetes in non-obese subjects (BMI < 25) during a five-year follow-up

From: Reduced lung function is independently associated with increased risk of type 2 diabetes in Korean men

  1. *P value was obtained from Chi-square tests for the comparison of incident diabetes among quartiles of FVC (% predicted) and FEV1 (% predicted).
  2. Model 1 was adjusted for age and BMI.
  3. Model 2 was adjusted as in model 1 plus education, smoking, exercise, alcohol and insulin.
  4. Model 3 was adjusted as in model 1 plus education, smoking, exercise, alcohol, HOMA-IR, TC, TG, and HDL-C.
  5. FEV1, forced expiratory volume in one second; FVC, forced vital capacity; OR, odds ratio; CI, confidence interval; BMI, body mass index; HOMA-IR, homeostasis model assessment – insulin resistance; TC, total cholesterol; TG, triglyceride; HDL-C, high-density lipoprotein cholesterol.
