Introduction: Pre-pregnancy obesity is an independent risk factor for adverse consequences of pregnancy. Increased awareness and sensitivity toward these consequences is the first step to promote preventive behaviors in this population. Extended parallel process model (EPPM) is known as a successful model in the prevention of health risky behaviors through raising awareness, sensitivity and self-efficacy of the people. Therefore, this study was performed with aim to compare traditional training (face to face) with Extended parallel process model (EPPM)-based Training on knowledge of obesity complications before pregnancy in women with high BMI.
Methods: This randomized clinical trial was performed with Multi-stage random sampling on 60 women referred to two health centers in Mashhad for pre-pregnancy counseling in 2015. For the experimental group, two training sessions were done by the researcher based on the model, and the control group received traditional training (face to face) by health care providers. Data collection tool was the questionnaire of concepts of model and knowledge of women from the risk of high weight before pregnancy which were completed before, two and four weeks after the intervention. Data were analyzed by SPSS software (version 16) and Independent T-test, Chi-square, Mann-Whitney and ANOVA with repeated data were used. P < 0.05 was considered significant.
Results: Before the intervention, there was no significant difference between the two groups in the mean score of knowledge (P>0.05). But after the intervention, significant increase was observed in the mean score of knowledge in the experimental group compared to the control group after two weeks (P<0.001) and four weeks (P<0.001).
Conclusion: Extended parallel process model-based training can act more successful than traditional training (face to face) in promoting the knowledge of women with high body mass index.
