Abstract

Background: Pregnancy complications are one of the major public health concerns. One of the main causes of preventable complications is the absence of or inadequate provision of prenatal care. The present study was conducted to investigate whether Extended Parallel Process Model’s constructs can predict the utilization of prenatal care services. Methods: The present longitudinal prospective study was conducted on 192 pregnant women selected through the multi-stage sampling of health facilities in Qeshm, Hormozgan province, from April to June 2015. Participants were followed up from the first half of pregnancy until their childbirth to assess adequate or inadequate/non-utilization of prenatal care services. Data were collected using the structured Risk Behavior Diagnosis Scale. The analysis of the data was carried out in SPSS-22 using one-way ANOVA, linear regression and logistic regression analysis. The level of significance was set at 0.05.Results: Totally, 178 pregnant women with a mean age of 25.31±5.42 completed the study. Perceived self-efficacy (OR=25.23; P<0.001) and perceived susceptibility (OR=0.048; P<0.001) were two predictors of the intention to utilize prenatal care. Husband’s occupation in the labor market (OR=0.43; P=0.02), unwanted pregnancy (OR=0.352; P<0.001), and the need to care for the minors or elderly at home (OR=0.35; P=0.045) were associated with lower odds of receiving prenatal care. Conclusion: The model showed that when perceived efficacy of the prenatal care services overcame the perceived threat, the likelihood of prenatal care usage will increase. This study identified some modifiable factors associated with prenatal care usage by women, providing key targets for appropriate clinical interventions.
