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 multi-stage random
sampling method. Data were collected using the international physical
activity questionnaire (IPAQ) and a researcher-made 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) had a
significant positive direct effect on physical activity behavior.
Moreover, instrumental attitude (β = 0.04, P = 0.003), subjective norms
(β = 0.04, P = 0.003) and perceived behavioral control (β = 0.03, P =
0.002) had a 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.
