Factors affecting physical activity among prediabetic women: the application of the Theory of Planned Behavior

Abstract

Background and aims: Prediabetic individuals are more at risk for developing diabetes mellitus (DM). Physical activity (PA) is a significant factor contributing to health maintenance and promotion. This study aimed to assess the factors affecting PA among prediabetic women based on the Theory of Planned Behavior (TPB). Methods: This cross-sectional study was conducted in 2019 on 100 prediabetic women selected from comprehensive healthcare centers in Arak, Iran. A demographic questionnaire, a TPB-based questionnaire, and Godin-Shephard Leisure-Time Physical Activity Questionnaire were used for data collection. Data were analyzed through the Spearman’s correlation analysis and the linear regression analysis with the backward method. Results: The mean score of PA was 0.56±0.8 (in the possible range of 0–2). Around 61% of participants had limited PA, 16% of them had moderate PA, 19% of them had adequate PA and 4% no response. Perceived behavioral control explained 5.5% of the variance of the PA behavior. Conclusion: Given the significant effects of perceived behavioral control on PA, TPB-based educations may be helpful in promoting PA among prediabetic women.
