Perceived susceptibility, perceived benefits, fewer perceived barriers, and higher self-efficacy significantly predicted adherence to Vitamin A supplementation, while perceived severity was not a significant predictor.
Key Findings
Results
Fewer perceived barriers was the strongest predictor of VAS adherence among all Health Belief Model constructs.
Adjusted odds ratio for fewer perceived barriers = 96.05 (95% CI: 21.84–422.30)
This was the largest AOR among all significant predictors identified in the logistic regression
Study used a cross-sectional design with 256 parents attending an immunization center
Data were collected through a validated questionnaire on knowledge and HBM constructs
Results
Perceived susceptibility was a significant predictor of VAS adherence, though only 28.1% of parents perceived their child as susceptible to Vitamin A deficiency.
Adjusted odds ratio for perceived susceptibility = 33.48 (95% CI: 4.62–242.71)
Only 28.1% of parents perceived their child as susceptible to Vitamin A deficiency
The wide confidence interval suggests variability in this estimate across the sample
Results
Perceived benefits significantly predicted VAS adherence, with 52.0% of parents recognizing the benefits of supplementation.
Adjusted odds ratio for perceived benefits = 8.82 (95% CI: 1.78–43.79)
52.0% of parents recognized the benefits of Vitamin A supplementation
Perceived benefits was identified as a significant predictor via logistic regression analysis
Results
Higher self-efficacy was a significant predictor of VAS adherence among parents.
Adjusted odds ratio for higher self-efficacy = 8.47 (95% CI: 2.32–30.89)
Self-efficacy was measured as part of the Health Belief Model constructs via a validated questionnaire
Self-efficacy was among the four HBM constructs that significantly predicted adherence
Results
Perceived severity was not a statistically significant predictor of VAS adherence.
Unlike the other four HBM constructs tested, perceived severity did not reach statistical significance in the logistic regression model
This finding diverges from some other HBM-based studies where severity typically drives health behavior
The study population consisted of parents of children aged 9–59 months attending an immunization center
Methods
The study used the Health Belief Model framework to assess predictors of Vitamin A supplementation adherence in a cross-sectional design.
256 parents attending an immunization center were included in the study
Parents of children aged 9–59 months were the target population
Data were collected through a validated questionnaire assessing knowledge and all HBM constructs
Logistic regression was the primary analytical method used to identify predictors of adherence
