  2. Each exercise type (up to three) reported by a person is counted in the corresponding category; therefore, the percentages may exceed 100
  3. Women who participated in both vigorous (> 6 MET) and moderate (3–6 MET) activities are included in the vigorous activity category
  4. §Active transportation to/from work; includes only women employed at the time of interview.
  5. ||Includes walking and cycling for daily errands (e.g. for shopping, etc)
