  • Adjusted simultaneously for age, race, waist circumference, pack-years of cigarette smoking, sport activity index, and ARIC center. HOMA-IR, homeostasis model assessment of insulin resistance.

  • *

    * Quartiles of FVC (% predicted) are sex specific.

  • HOMA-IR = (fasting insulin [μU/ml] × fasting glucose [mmol/l]/22.5).

  • P values correspond to tests for linear trend across quartiles.
