Abstract
Background and Objectives: Pregnant women’s oral and dental hygiene is of great importance to maternal and neonatal health. This study aimed to predict dental caries preventive behaviors among pregnant women based on self-efficacy and the theory of planned behavior. Methods: This cross-sectional descriptive-analytical study was conducted in 2016 on 258 pregnant women recruited from comprehensive healthcare centers in Birjand, Iran. Sampling was done via multistage random sampling. Data collection instrument was a researcher-made questionnaire developed based on self-efficacy and the theory of planned behavior. The content validity of the instrument was approved by 10 faculty members and its reliability was approved with a Cronbach’s alpha of 0.77. Pearson correlation analysis and multiple linear regression analysis were conducted via the SPSS software (v. 19.0) to analyze the data at a significance level of less than 0.05. Results: The mean of participants’ age was 27.6 ± 5.1 and the mean of the decayed, missing, and filled teeth index was 5.4 ± 3.5. Regression analysis showed that self-efficacy and the constructs of the theory of planned behavior explained 47% of the total variance of the intention to show dental caries preventive behaviors. The strongest predictors of behavioral intention were self-efficacy (R2 = 0.34) and the subjective norm construct of the theory (R2 = 0.313). Conclusions: Self-efficacy and subjective norm are the strongest predictors of dental caries preventive behaviors among pregnant women. The combination of self-efficacy and the theory of planned behavior can provide a useful framework for developing and implementing educational interventions for the prevention of dental caries among pregnant women and the promotion of maternal and neonatal health.
