title: [Analyses on the characteristics and the trends of pneumoconiosis notified between 2001 and 2012 in Hebei Province].
abstract: OBJECTIVE
  To describe the incidence, development and death of pneumoconiosis reported in Hebei from 2001 to 2012 and investigate the epidemiological trends and characteristics of pneumoconiosis to provide basic data for formulating the guidelines and policies for control of pneumoconiosis.
  
  
  METHODS
  The Hebei database of new cases of pneumoconiosis reposed from 2001 to 2012 were subjected to systematic arrangement. Clean data and descriptive analysis using SPSS 17.0. The statistical indices included number of new and death pneumoconiosis cases in each year.
  
  
  RESULTS
  From 2001 to 2012 a total of 4558 new cases of pneumoconiosis were reported. The situation was same to coal-workers' pneumoconiosis and silicosis. (2) The pneumoconiosis cases were distributed mainly in the city of Tang Shan, Cheng De, Zhang Jia Kou and Han Dan (88.24%). (3) Most cases were centerred in coal industry, metallurgical industry, nonferrous metals industry, architectural material industry and light industry. (4) The mean age of onset in new cases was shorted each year for silicosis, coal-workers' pneumoconiosis, potter pneumoconiosis and electric welder pneumoconiosis, especially for 2010 to 2012 (9 years). (5) The work types of these cases mainly included drilling (26.72%), mining as the main work (6.67%), hybrid coal mine work (6.95%), molding worker (5.24%) and berterring worker (4.82%). (6) The new cases of pneumoconiosis reposed from 2001 to 2012 were diagnosissed I (3415, 74.92%), II (782, 17.16%), III (361, 7.92%). (7) The death cases of pneumoconiosis reposed from 2001 to 2012 were 1182, most of them were distributed mainly in the city of Tang Shan, Cheng De, Zhang Jia Kou and Han Dan (88.24%).
  
  
  CONCLUSIONS
  The incidence of pneumoconiosis is still high: the new cases of pneumoconiosis is still rising. The mean age of onset in new cases was shorted each year. The new cases of pneumoconiosis reposed from 2001 to 2012 were diagnosed II was above 25%. The prevention and control of pneumoconiosis should be enhanced in key industries and for people engaging in key regions, industries, types of work according to the epidemiological characteristics of pneumoconiosis. Most cases were centerred in coal-workers' pneumoconiosis and silicosis.
