To clarify the spatial and temporal distribution pattern of the incidence of non-occupational carbon monoxide poisoning in Shandong Province, to reveal the meteorological driving factors behind it, and to provide reference for its scientific prevention and control.
Non-occupational carbon monoxide poisoning incident reports were collected through the China Disease Control and Prevention Information System Public Health Emergency Reporting Management Information System. Descriptive analysis was used to study the prevalence characteristics of non-occupational carbon monoxide poisoning. Spatial autocorrelation analysis and spatio-temporal scanning analysis were performed to explore spatio-temporal aggregation using ArcGIS 10.7 and SaTScan 10.1.2 software, respectively. The influence of meteorological factors on the incidence of non-occupational carbon monoxide poisoning was assessed using an optimal parameter geographical detector.
A total of 12 088 cases of non-occupational carbon monoxide poisoning were reported in Shandong Province from 2019 to 2023, with peak incidence from November to March of the next year each year, and middle-aged and older populations people as the main high-risk groups. Global spatial autocorrelation analysis showed spatial clustering of non-occupational carbon monoxide poisoning incidence rates in both 2020—2022(P<0.05). The southern part of Shandong Province was gradually developing into a new hot spot. Spatio-temporal scanning analysis detected five aggregation zones, of which the primary aggregation zone was mainly concentrated in the northern part of Shandong Province (Nov 2019—Mar 2021, LLR=2 003.71, P<0.001). The results of the optimal parameter geographical detector showed that relative humidity and barometric pressure were important meteorological factors affecting morbidity, with the largest interaction between relative humidity and wind speed.
Non-occupational carbon monoxide poisoning in Shandong Province showed seasonal spatiotemporal clustering. It is recommended to strengthen the winter and spring health education work for middle-aged and older populations and other high-risk groups. At the same time, disease prevention and control organizations at all levels should establish good information communication with meteorological and propaganda departments. Early warning of non-occupational carbon monoxide poisoning accidents in key endemic areas such as northern Shandong Province and southern Shandong Province should be strengthened through these initiatives.
