Predicting physical activity among low-income Mexican American women: application of the theory of planned behavior

Am J Health Behav. Mar-Apr 2007;31(2):115-22. doi: 10.5555/ajhb.2007.31.2.115.


Objectives: 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.
