To evaluate a culturally appropriate intervention to increase activity
in overweight Mexican American women. Methods: Participants
were randomly assigned to a physical activity program or wait-list
control. Results: Treated participants were not more active
than controls at 6 or 12 months. In addition, we found no significant
differences in the proportion of individuals who met an objective
criterion for physical activity from baseline to 6 months in the
treatment or control groups. Conclusion: The intervention
did not increase physical activity in this population. Differences
in baseline activity and contamination of the control group may
partially account for the outcome.
