PNA Dataset: Pulmonary Function and Pneumonia History in People with HIV

259 participants with HIV in San Francisco were categorized by number of pneumonia episodes to analyze lung function decline. The dataset, created by Sven J. Walderich and last updated in April 2026, shows a stepwise decline in FEV1, FVC, and DLCO %predicted with recurrent pneumonia. Having three or more pneumonias was associated with significantly higher odds of airflow obstruction and impaired diffusion capacity.

Use Cases

• Modeling the association between pneumonia recurrence and lung function decline based on FEV1, FVC, and DLCO metrics.
• Predicting the risk of airflow obstruction in people with HIV based on pneumonia history and covariates like substance use.
• Comparing pulmonary outcomes between different types of pneumonia (e.g., bacterial vs. Pneumocystis) as mentioned in the results.

Strengths

• Includes data for 259 participants with detailed clinical and demographic breakdowns (e.g., 15% female, 42% current smokers).
• Analysis adjusts for substance use and HIV-associated factors, suggesting a structured covariate set.
• Results show statistically significant trends (p-trend <0.001) and odds ratios with confidence intervals, indicating rigorous analysis.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Data is from a single location (San Francisco, CA), which may limit geographic generalizability.
• The dataset is very small at 70.8 KB, indicating limited scope.
