Assessing Parental Understanding and Perspectives on Vitamin A Supplementation for Children: A Quantitative Study using the Health Belief Model.

TL;DR

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

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

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

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

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

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

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
