Background Due to the fact that pre-diabetic people are at higher risk of developing diabetes, it is possible to reduce the risk by taking preventive measures. Therefore, the present study aimed to determine the effect of theory-based education on promoting a healthy lifestyle and fasting blood sugar (FBS) in pre-diabetic women. Methods This is a cluster‐randomized controlled trial that was performed on 71 pre-diabetic women referred to Arak Comprehensive Health Service Center. Thus, using cluster sampling method, one center was randomly assigned to the intervention group and one center to the control group. The data collection tool was a questionnaire based on the theory of planned behavior (TPB) and healthy lifestyle behavior that was completed before and at least 3 months after training and FBS test was performed. The experimental group received 3 training sessions of 60 to 90 min and finally the data were analyzed using statistical software. Results After the intervention, the mean scores of knowledge (P < 0.001), attitude (P = 0.047) and perceived behavioral control related to physical activity (P = 0.046) and dietary function (P = 0.01) increased significantly in the intervention group. In addition, fasting blood sugar in the intervention group (99.70 ± 11.06) improved significantly compared to the control group (110.94 ± 17.09) (P = 0.003). Conclusion Education based on the theory of planned behavior, by holding face-to-face meetings along with following up the samples after the educational intervention, can promote healthy lifestyle of pre-diabetic women. Therefore, designing and implementing similar interventions on all pre-diabetic individuals seem necessary.

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.
