  • Data are means (95% CI). Values are weighted to the Australian population, with unadjusted means and percentages. Geometric means are reported for fasting insulin, HOMA-%S, and HOMA-%B. Statistical comparisons are age adjusted.

  • *

    * P < 0.05 for comparison of men and women. IFG, impaired fasting glucose; IGT, impaired glucose tolerance; TV, television.
