The health belief model and self-determination theory in explaining the use of antenatal care services: a cross-sectional study

Abstract

Introduction Antenatal care services are vitally important in monitoring pregnancy and identifying the risk factors during pregnancy. However, many pregnant women under-use these services and factors associated with under-use are not well explained. Therefore, this study aimed to use the health belief model and self-determination theory to explore antenatal care services use among postnatal women in the Mara region. Methods A hospital-based cross-sectional study involving postnatal women from April to July 2020 was conducted using a structured questionnaire. A total of 384 postnatal women were recruited using systematic sampling. The associations between constructs of the health belief model and self-determination theories with antenatal care service variables were examined using the Chi-squared test, followed by logistic regression analysis. P<0.05 at 95% confidence interval was considered statically significant. Results Of 384 participants, 53.4% were self-determined on antenatal care services use, 46.9% had a high level of perception on antenatal care services use and 49.7% had adequate knowledge on antenatal care services use. Being from the Kurya tribe reduced the odds of being self-determined. Most (85.9%) postnatal women had attended fewer than eight recommended antenatal care visits. Multivariate analysis showed low autonomy (P=0.038), and low perceived barriers (P=0.007) were predictors for antenatal care visits. Conclusions Antenatal care services are still inadequately used in the Mara region. Low perceived autonomy and low perceived barriers are significantly associated with antenatal care services use. Health management teams and health stakeholders should collaborate to improve the situation.

A qualitative analysis of community health worker perspectives on the implementation of the preconception and pregnancy phases of the Bukhali randomised controlled trial

“…For Bukhali, our results highlighted the importance of ongoing training of the HHs, with emphasis on how to adapt sessions and explanations in multiple ways, using pictures, drawings, and different languages and avoiding adverse tactics such as using exaggerated claims to scare participants into action. Such training could include, for example, bio-ethical considerations around fear appeals, and their potential, in the framework of the health belief model, for influencing behaviour change through increased perceived severity and PLOS GLOBAL PUBLIC HEALTH susceptibility, only if used appropriately [43][44][45][46]. In the broader context of CHW programmes across South Africa, which requires coverage across demographics, cultural variations, and rural versus urban settings, programmes will likely benefit from an emphasis on adaptability on CHW programme level [2], and on the individual CHW-patient level [23].…”

Healthcare utilization among informal caregivers of older adults in the Ashanti region of Ghana: a study based on the health belief model

“…Their study revealed that perceived susceptibility and perceived seriousness play a role in the utilization of health preventive services among young adults. In Tanzania, Tungaraza and Joho [ 73 ] employed the HBM and self-determination theory to explain the use of antenatal care services. They reported that low perceived barriers are associated with antenatal care visits in Tanzania.…”

Protocol to develop a framework addressing barriers to utilization of elimination of mother- to -child transmission of HIV services among pregnant women and lactating mothers in Gauteng province

“…According to the HBM, a person's belief in a personal threat of disease and confidence in the efficiency of the recommended health behavior or activity predicts the likelihood that such a person would adopt the practice. The model attempts to justify the premise that health-seeking behavior is influenced by the individual perceptions of threats posed by a health problem and the perceived benefits of taking action to minimize a health problem [ 32 , 33 ]. HBM is being applied in this study to identify/understand the reasons for poor utilization of EMTCT services among women by looking at their perception of susceptibility, seriousness, benefits, barriers to behavior, cues for action, and efficacy ( Fig.…”
