We know that
 Physical inactivity is a problem.
 The social environment plays an important role on
behavior.

BUT…Do the frameworks we have fit women?
 …who are less physically active than men?
 …have different social and cultural norms?

Ethnic minority women with low physical
activity support are more likely to be
sedentary
Women with high support were more likely to
 Meet leisure-time physical activity
recommendations (≥150 min/week)
 Lead a physically active lifestyle (~300 min/week)

child (OR=2.06)

To even do it. And the
