  • Total n = 17,869 (normoglycemia, 16,826; glucose intolerance, 987; new diabetes; 56).

  • * Means and percents are adjusted for age (age is unadjusted).

  • P < 0.001 compared with normoglycemic group.

  • Information on first-degree relatives (parents, siblings, or children) with CHD ascertained on 6,206 participants. FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity.
