Improving prenatal care in pregnant women in Iranshahr, Iran: Applying Health Belief Model

Abstract

ABSTRACTTo determine the effect of an education-based intervention on receiving adequate prenatal care. This randomized, controlled trial was conducted on 90 primiparous pregnant women, referred in Iranshahr, Iran for prenatal care (intervention = 45, control group = 45). The data were collected from February to June 2016 using a questionnaire developed based on the Health Belief Model (HBM). The intervention group received three intervention sessions during the second trimester of pregnancy, and 3 months after intervention, both groups completed a questionnaire. Data were analyzed using independent sample t-tests, chi-squared tests, paired t-test, Pearson and multivariate regression. Unlike the control group, in the intervention group’s mean scores for knowledge, variables from the HBM model and frequency of prenatal care significantly differed from pre- to post-intervention (pre-intervention mean = 12.62 ± 2.63, post-intervention mean = 17.71 ± 1.56, (p ˂ 0.05). Self-efficacy was positively correlated with knowledge (r = 0.304, p = 0.02) and adequate prenatal care (r = 0.583, p ˂ 0.001). The constructs of the HBM explained 75% of the variance in frequency of prenatal care in multivariable models. Developing an educational program based on the HBM was effective in the adoptation of prenatal care. Additionally, considering social, economic, and educational follow-up while implementing these programs is recommended.
