Social deprivation and asthma
Insights
Children in socially deprived areas face higher hospital admission rates for asthma. This is linked to environmental factors like smoking, not necessarily higher asthma prevalence, suggesting treatment and environmental improvements are key.
Area of Science:
- Public Health
- Pediatric Medicine
- Environmental Health
Background:
- Social deprivation is a known factor influencing health outcomes.
- Asthma remains a significant pediatric respiratory illness with varying admission rates.
- Understanding the drivers of asthma hospitalizations in vulnerable populations is crucial.
Purpose of the Study:
- To investigate the association between social deprivation and pediatric asthma hospital admissions.
- To determine if higher asthma prevalence or poorer treatment contributes to excess risk in deprived areas.
- To explore the role of environmental factors, such as smoking, in asthma exacerbations.
Main Methods:
- Correlation analysis of asthma hospital admission rates with Townsend indices of deprivation across Cardiff electoral wards.
- Schoolchildren survey on respiratory symptoms, comparing prevalence with deprivation indices and admission rates.
- Assessment of factors like household smoking and inhaled corticosteroid use in relation to social deprivation.
Main Results:
- Strong positive correlation found between asthma hospital admissions and social deprivation (Townsend index) across all age groups.
- No significant correlation between asthma symptom prevalence and social deprivation or admission rates.
- Household smoking significantly associated with higher asthma admission rates and symptom severity.
- Non-significant negative association between social deprivation and inhaled steroid use.
Conclusions:
- Social deprivation is strongly linked to increased pediatric asthma hospitalizations, independent of asthma prevalence.
- Environmental factors, particularly household smoking, appear to aggravate asthma symptoms and contribute to hospital admissions in deprived areas.
- Differences in asthma management or treatment adherence may also play a role in the observed disparities.
Abstract:
This study was conducted to see whether children living in socially deprived areas were more likely than other children to be admitted to hospital for asthma, and, if so, whether their excess risk was attributable to a higher prevalence of asthma or poorer treatment. Hospital admission rates for asthma were obtained for Cardiff electoral wards and compared with the Townsend indices of deprivation. A survey of respiratory symptoms was conducted in schoolchildren; prevalence of symptoms was compared with Townsend index and asthma admission rate for the schools' catchment areas. Asthma admissions were strongly correlated with Townsend indices at all ages. The prevalence of reported asthma and various degrees of wheeze in the schools was not significantly correlated with Townsend index or hospital admission rate in the corresponding areas. The presence of a smoker in the house was strongly associated with Townsend index and admission rate; children whose houses contained a smoker were more likely than others to have wheezed in the past year and to have disturbed nights due to wheezing. There was a non-significant negative association between Townsend index and regular use of inhaled steroids. The relationship between hospital admission for asthma and social deprivation is not explained by variations in prevalence, but it may be attributable to the aggravation of symptoms by active or passive smoking, and perhaps also to differences in management.
