title: [Disease burden of gastric cancer in Jinchang cohort].
abstract: OBJECTIVE
  To understand the current status of disease burden caused by gastric cancer in Jinchang cohort.
  
  
  METHODS
  In this historical cohort study, the data of gastric cancer deaths from 2001 to 2013 and the medical records of gastric cancer cases from 2001 to 2010 in Jinchang cohort were collected to analyze the mortality, potential years of life lost (PYLL), working PYLL (WPYLL) associated with gastric cancer, and the medical expenditure data were used to evaluate the direct economic burden. Spearman correlation analysis and the average growth rate were used to describe the change trend of disease burden of gastric cancer.
  
  
  RESULTS
  A total of 213 gastric cancer deaths occurred in Jinchang cohort from 2001 to 2013. The average annual crude mortality rate of gastric cancer was 38.30 per 100,000 in Jinchang cohort during 2001-2013 and no obvious change was observed. The crude mortality rate in males was 6.84 times higher than that in females. Gastric cancer death mainly occurred in age group 50-79 years (82.62%), while the mortality rates was increasing among the people under 50 years with an average annual increase rate of 0.77%. The annual average PYLL (APYLL) and average WPYLL (AWPYLL) caused by gastric cancer decreased by 8.43% and 10.46%, respectively. No obvious change in medical expenditure of gastric cancer cases was observed in Jinchang Cohort during 2001-2010, and the medical expenditure and average daily cost of hospitalization were 8102.23 Yuan, and 463.45 Yuan per capita, respectively.
  
  
  CONCLUSIONS
  The burden of disease for gastric cancer was heavy in Jinchang cohort. The PYLL and WPYLL had no change, while the APYLL and AWPYLL showed a increasing trend during the last ten years. Direct economic burden of inpatients with gastric cancer had no change.
