  • *Data were only available on patient behavior, if recommendation for exercise was given at all. NHANES did not indicate the chronological order of the physician recommendations and the actual change in exercise or diet so it is not possible to determine if lifestyle behaviors changed in response to recommendations. Applying WHO IFG criteria (FPG 110–125) showed similar results.

  • †Rates of recommendation for these specific exercise categories were not reported in NHANES.

  • ‡Only available for those with diagnosed pre-diabetes.
