Abstract

Background: Theory of planned behavior (TPB) has not been adequately addressed in the field of physical activity among Iranian women. Objectives: This study aimed to determine factors affecting physical activity behavior among women based on the theory of planned behavior. Methods: This cross-sectional study was conducted on 398 women in Kerman, Iran. The women were selected through the multistagerandomsampling method. Data were collected using the international physical activity questionnaire (IPAQ)anda researchermade questionnaire based on the constructs of the theory of planned behavior and analyzed using structural equation modeling (SEM). Results: The mean age (SD) of participants was 36.9 (9.9). Perceived behavioral control (β= 0. 16, P = 0. 013) and behavioral intention (β=0.16, P=0.005)hada significant positive direct effectonphysical activitybehavior. Moreover, instrumental attitude (β=0.04, P= 0.003), subjectivenorms (β=0.04, P=0.003)andperceived behavioral control (β=0.03, P=0.002)hada significant positive indirect effect on physical activity behavior. Behavioral intention and perceived behavioral control constructs predicted 6% of variance of physical activity behavior. Conclusions: Given that the constructs of behavioral intention and perceived behavioral control could predict physical activity behavior, health promotion interventions should be designed with an emphasis on these factors in order to promote physical activity in women. © 2017, Iranian Red Crescent Medical Journal.
