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

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).

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.

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.

Given the significant effects of perceived behavioral control on PA, TPB-based educations may be helpful in promoting PA among prediabetic women.
