  1. aAdequate exercise regimen is defined as > = 150 min of moderate activity per week or > =75 min of vigorous activity per week or some combination of moderate and vigorous that is equivalent to these guidelines. Moderate activity is 3 to < 6 METs. Vigorous activity is 6+ METs
  2. 2/P-values are shown for chi-square tests of association between leisure-time physical activity trajectory class and percent of women with adequate exercise regimen for the specific study visit
