Predicting physical activity among low-income Mexican American women: application of the theory of planned behavior.
OBJECTIVE
To utilize the theory of planned behavior (TPB) in explaining the prediction of physical activity intention and determine if present activity behavior attenuates theory construct relationships in a sample of low-income Mexican women.


METHODS
Data were gathered on 201 subjects through a self-report survey instrument and analyzed through structural equation modeling.


RESULTS
Present activity behavior attenuated theory construct influence on intention, and perceived behavioral control was the strongest predictor of intent to engage in physical activity.


CONCLUSIONS
Interventions promoting voluntary physical activity for this population group should address factors perceived as barriers to participating in activity situations.
