Abstract

Introduction: A suggested method to improve the outcomes of pregnancy with sickle cell disease (SCD) is to engage more women at reproductive age in preconception healthy behavior (PCHB). Social marketing can be a suitable strategy to achieve this goal. We aimed to assess the impact of the social marketing-based intervention on women's engagement in PCHB.

Methods: A quasi-experimental study was conducted in Bandar Abbas and Minab (the two largest cities of Hormozgan province in Iran with a high prevalence of SCD) from 2021 to 2022. A social marketing-based intervention with the main components (participation in PCHB as a "product," social media and traditional promotional channels as a "promotion," selecting healthcare centers as a "place" for implementing the intervention, and free access to medical experts and speciality as a "price") was designed based on formative research. The sample size was estimated at 140 participants in each intervention and control group. The study's main outcome was the level of engagement in PCHB, which was assessed according to the health belief model (HBM).

Results: We compared the PCHB scores of both groups. Employing healthy behavior was more dominant in the intervention group. Awareness, perceived severity, perceived susceptibility, perceived benefits, and self-efficacy increased in both groups following intervention, while perceived barriers decreased. An analysis of covariance (ANCOVA) was performed to control and moderate the effect of scores in the pretest. As observed between the adjusted averages, awareness, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and engagement in the PCHB were significantly different between the control and intervention groups after the intervention. A multivariate linear regression analysis showed that awareness, perceived susceptibility, and self-efficacy were strong predictors of PCHB.

Conclusions: Social marketing-based intervention successfully increased PCHB among women of reproductive age with SCD.
