  • NOTE: Values for mean frequency, duration, and total minutes of leisure-time exercise activity are calculated based only on women reporting some exercise activity in that category.

  • * % Sample reporting any activity in that category.

  • Number of times exercised per week.

  • In minutes per week, based on women reporting physical activity in that intensity category only.

  • § In minutes per week, based on mean frequency times mean duration.

  • Data collected at the baseline assessment represent pre-diagnosis exercise activity.

  • Defined as absence of any physical activity of any intensity.

  • ** Defined as ≥150 min of moderate or strenuous activity per week.
