Abstract:
Objective:To explore the temporal and spatial characteristics of pneumoconiosis in Hebei Province from 2009 to 2018, and to provide evidence for the policy development of pneumoconiosis prevention and control.Methods:In February 2019, a database of pneumoconiosis incidence from 2009 to 2018 in Hebei Province was built. The spatial-temporal distribution of pneumoconiosis in Hebei Province was displayed based on barycenter migration technology and spatial autocorrelation analysis.Results:A total of 6099 cases of pneumoconiosis were reported in Hebei Province from 2009 to 2018, the top 5 pneumoconiosis were silicosis(4399, 72.13%) , coal worker pneumoconiosis (1298 , 21.28%) , ceramics pneumoconiosis (224, 3.67%) , welding worker's pneumoconiosis(76, 1.25%) , and casting worker's pneumoconiosis(48, 0.79%). The focus of pneumoconiosis from 2009 to 2014 moved from Tangshan in the northeast to Zhangjiakou in the northwest, and moved to Chengde in the north from 2015 to 2017, and moved back to Tangshan in 2018. The incidence of pneumoconiosis was globally autocorrelation ( P <0.05) from 2009 to 2011 and 2014 to 2018. The high-high gathering areas were located in Zhangjiakou, Chengde and other areas. Conclusion:The barycenter of pneumo- coniosis in hebei province from 2009 to 2018 is relatively stable, mainly locates in the northern part of Hebei Province over the years. There is an obvious regional aggregation, and the aggregation type is mainly high-high aggregation, which indicates that relevant departments should focus on strengthening the prevention and treat- ment of aggregation areas on the basis of overall planning.
