Insights
Vaccination coverage is lower in families with many children and fathers with low education. These factors, along with childcare resources, influence childhood immunization rates.
Area of Science:
- Pediatric Health
- Public Health Policy
- Sociology of Health
Background:
- Socio-economic and demographic factors are linked to low childhood vaccination coverage.
- The intricate relationships between these factors remain unclear.
- This study investigates familial resources for childcare and their connection to vaccination rates and socio-demographic influences.
Purpose of the Study:
- To examine the association between parental social status, childcare resources, and measles vaccination coverage in schoolchildren.
- To explore the interrelationships among these determinants using a hierarchical model.
Main Methods:
- Cross-sectional study of 2386 schoolchildren aged 6-13 years in Styria, Austria.
- Utilized a conceptual hierarchical model to analyze determinants of vaccination coverage.
- Employed graphical modeling for multivariate analysis of hierarchically structured data.
Main Results:
- High number of children in the family showed a direct association with lower vaccination coverage (P < 0.0001).
- Low paternal education was directly and indirectly associated with reduced vaccination coverage (P < 0.001).
- Other childcare resources indirectly impacted coverage, with family size being a key mediator.
Conclusions:
- Vaccination programs should target families with numerous children and parents of lower educational backgrounds.
- A focused approach on specific high-risk groups may be more effective than population-wide strategies.
Background:
Numerous socio-economic and demographic factors have been identified as being associated with low vaccination coverage in children. However, the complex interrelation between these factors is not fully understood. We focused our study on the less well-established associations of familial resources for child care with vaccination coverage and their interrelationship with socio-demographic factors.
Methods:
This cross-sectional study (n = 2386) focuses on parental social status and on resources for child care as determinants of measles vaccination coverage of schoolchildren aged 6-13 years in Styria, Austria. In order to reveal the relationships among these factors, an analysis based on a conceptual hierarchical model was performed. The so-called graphical modelling approach was used for the multivariate analysis of the hierarchically structured determinants.
Results:
The findings indicate that vaccination coverage is directly associated with a large number of children in the family (P < 0.0001) and directly as well as indirectly associated with a low level of education of the father (P < 0.001). All other included child-care resources are only indirectly associated with a low coverage, whereby the number of children acts as main mediating factor.
Conclusions:
The results suggest that vaccination programmes should mainly focus on families with many children or parents of low educational level and not on the whole population.
