Description
Taubaté, Brazil, hospitalization data for respiratory diseases from August 2011 to July 2012, linked with estimated daily concentrations of air pollutants (CO, PM2.5, O3, NOx) and meteorological variables. The dataset contains 352 admissions and was used in a Poisson regression analysis to quantify health risks, finding a 17% increased hospitalization risk for a 3µg/m³ rise in nitrogen oxides. The research was conducted by Vanessa Villalta Lima Roman using data from Datasus and pollutant estimates from the CATT-BRAMS model.
Use Cases
Modeling the association between estimated nitrogen oxide levels and hospital admissions based on lagged exposure analysis.
Assessing the impact of apparent temperature (derived from temperature and humidity) on respiratory disease outcomes.
Validating mathematical models for air pollutant estimation in cities without physical monitoring stations.
Conducting time-series regression analysis on health outcomes using a multipollutant model framework.
Strengths
Dataset is based on 352 specific hospitalization records over a defined one-year period.
Analysis includes estimated concentrations for four key pollutants (CO, PM2.5, O3, NOx) and adjusts for meteorological confounders.
The study provides specific risk estimates, such as a 17% increased hospitalization risk for a 3µg/m³ rise in NOx.
Limitations
Row count for the underlying raw data is unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
Data may reflect geographic and temporal bias specific to Taubaté, Brazil, in 2011-2012.
Provenance
Source
Datasus (hospitalization data) and CPTEC-INPE/CATT-BRAMS model (pollutant and weather data).
