Insights
Socioeconomic factors significantly impact infant bronchiolitis hospitalizations. Infants in areas with higher social burden, like increased immigrant populations, faced nearly double the hospitalization rates.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Background:
- Bronchiolitis is a leading cause of infant hospitalization.
- Understanding factors influencing hospitalization is crucial for public health interventions.
Purpose of the Study:
- To investigate the relationship between socioeconomic factors and bronchiolitis hospitalization rates in infants.
- To determine if socioeconomic status affects disease severity in hospitalized infants.
Main Methods:
- Retrospective study of infants under 1 year hospitalized for bronchiolitis in Malmö, Sweden (1998-1999).
- Calculation of bronchiolitis hospitalization rates (BHRs) per residential area.
- Correlation analysis of BHRs with socioeconomic indicators (immigrant percentage, income, unemployment, social benefit).
- Assessment of disease severity using oxygen saturation, supplemental oxygen duration, and length of stay.
Main Results:
- Bronchiolitis hospitalization rates varied over fourfold across 10 residential areas.
- Significant correlations found between BHRs, per capita income, and immigrant percentage.
- Infants from areas with higher social burden had nearly double the hospitalization rate compared to the city average.
- Disease severity was similar across all areas, irrespective of socioeconomic status.
Conclusions:
- Socioeconomic factors are significantly associated with bronchiolitis hospitalization rates in infants.
- These findings suggest that socioeconomic determinants play a crucial role in the epidemiology of infant bronchiolitis.
- Targeted public health strategies in disadvantaged areas may reduce infant hospitalization for bronchiolitis.
Unlabelled:
Bronchiolitis is a major cause of hospitalization during infancy. The aim of this study was to evaluate the influence of socioeconomic factors on the hospitalization of infants with bronchiolitis. All infants below 1 y of age living in the city of Malmö, Sweden, and hospitalized at the University Hospital. Malmö, owing to bronchiolitis during the years 1998 and 1999 were identified. The bronchiolitis hospitalization rates (BHRs) were determined for the infants living in each of the 10 different administrative residential areas of Malmö and correlated with socioeconomic factors (percentage of immigrants, per capita income, unemployment rate and households receiving social benefit) in the respective residential areas. The severity of the disease on admission and during hospital care was assessed by comparing oxygen saturation, days with supplemental oxygen and length of stay. BHR varied more than fourfold between the 10 residential areas. BHR varied significantly with per capita income and the percentage of immigrants. Infants living in the area with the highest social burden were hospitalized almost twice as often as those from the rest of the city, but the severity of disease was similar.
Conclusion:
The association between socioeconomic factors and hospitalization indicates that these factors may have a significant influence on the hospitalization rate in bronchiolitis during infancy.
