Determinants of Physical Activity in Young Adult Cancer Survivors.

Objectives: To examine the determinants of physical activity (PA) in young adult cancer survivors (YACS). Methods: A survey of 588 YACS in Alberta, Canada, assessed PA, medical and demographical factors, and theory of planned behavior variables. Results: Path analysis explained 38% (P<.001) of the variance in PA with significant contributions from intention, planning, affective attitude, education, and general health. In turn, 56% (P<.001) of the variance in intention was explained by perceived behavioral control, instrumental attitude, and affective attitude. Conclusion: PA interventions in YACS should focus on developing strong intentions by targeting perceived behavioral control, instrumental attitude, and affective attitude. [ABSTRACT FROM AUTHOR]
