Background
Immunizations protect children from deadly infectious diseases. Yet, there is still insufficient understanding of the factors associated with parents’ non-adherence to immunizations in contexts outside of Western countries. The aim of this study is twofold: (a) to investigate non-adherence to immunizations for children aged 6 months to 6 years in Saudi Arabia based on the number of immunizations missing or delayed by more than one month; and (b) to examine the underlying factors that predict the extent of non-adherence based on the Health Belief Model framework.
Methods
A cross-sectional study was carried out in 22 randomly selected primary health care centers. Structured interviews were also conducted to collect data using the modified Health Belief Model questionnaire. Multiple regression analysis was used to assess the predictors of the extent of non-adherence.
Results
Based on data from 220 participants, 51.8% of parents did not adhere with childhood immunizations. There was no significant relationship between parents’ sociodemographic characteristics and the extent of their hesitancy about children’s immunizations. The linear combination of perception of infectious disease severity, perception of their children’s susceptibility, perception of immunization benefits, perception of fewer barriers to obtaining immunizations, cues to action related to immunizations, and self-efficacy predicted the extent of non-adherence to immunizations (F (11.220) = 2.595, p < 0.001) and explained 12% of its variance. Yet, only perceived children’s susceptibility, perceived barriers, and self-efficacy independently predicted parents’ non-adherence.
Conclusion
Saudi Arabia’s high proportion of non-adherence to childhood immunizations should be addressed. For instance, a health education program could be developed to increase parents’ awareness that their children are susceptible to health risks. Paying a special attention to existing barriers in accessing and receiving the immunizations is crucial. In addition, building parents’ self-efficacy, which is confident in making healthy decisions, such as keeping their children’s immunizations up to date, is important.
