Pollution and childhood pneumonia in Lima - Supplementary material - Data

These data include the aggregated childhood pneumonia cases by district, which were obtained from the epidemiological surveillance system of the Ministry of Health (MINSA), which integrates information from all health centers in each district. Additionally, the data include the weekly PM₂.₅ concentrations that were retrieved from open data provided by the National Service of Meteorology and Hydrology of Peru (SENAMHI), which conducts environmental monitoring through sentinel stations located in each district included in the study. Exposure was operationalized using the weekly median PM₂.₅ concentration expressed in µg/m³.

本数据集涵盖按行政区汇总的儿童肺炎病例数据，此类数据源自秘鲁卫生部（Ministry of Health, MINSA）的流行病学监测系统，该系统整合了各行政区内所有卫生中心的相关监测信息。此外，数据集还包含每周PM₂.₅浓度数据，该类数据取自秘鲁国家气象与水文局（National Service of Meteorology and Hydrology of Peru, SENAMHI）提供的公开数据集；该机构通过本研究涉及的各行政区内的哨兵站点开展环境监测工作。本研究以单位为微克每立方米（µg/m³）的周度PM₂.₅浓度中位数作为PM₂.₅暴露水平的操作化定义。
