Korean Asthma Hospitalization Prevalence by Age and Sex, 2002–2019

1,137,861 participants from a Korean national health insurance cohort were analyzed for hospitalization-requiring asthma exacerbations from 2002 to 2019. The data provides annual prevalence rates per 10,000 person-years, stratified by six age groups and sex, with trends analyzed via joinpoint regression. This supplementary material was authored by figshare admin karger and published on figshare.

Use Cases

• Analyzing long-term trends in severe asthma outcomes based on annual prevalence rates from 2002 to 2019.
• Comparing asthma hospitalization risk across different age groups, such as infants, adolescents, and older adults.
• Investigating sex-based disparities in asthma exacerbation prevalence before and after age 12.
• Modeling the annual average percentage change (AAPC) in asthma exacerbation rates for specific demographic segments.

Strengths

• Data covers 1,137,861 participants from a national sample cohort, providing a large-scale population basis.
• Longitudinal coverage spans 18 years (2002–2019), allowing for trend analysis.
• Results are stratified by six distinct age groups and sex, enabling detailed demographic comparisons.
• Prevalence is reported in specific rates (e.g., cases per 10,000 person-years) for precise quantification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document (183.3 KB), suggesting the dataset is small and likely contains summary statistics rather than raw patient-level records.
