title: [Burden of disease in schistosomiasis japonica. II. Measurement of health inequalities due to chronic schistosomiasis].
abstract: OBJECTIVE
  To measure and evaluate the health inequalities due to chronic schistosomiasis japonica.
  
  
  METHODS
  Based on years lived with disability (YLD) caused by chronic schistosomiasis, a concentration index and Gini index, along with a concentration curve and Lorenz curve, the health inequalities between sexes, age groups or endemicities were identified and quantified.
  
  
  RESULTS
  The age concentration index was 0.395 of females and 0.380 of males, with no significant difference between them. More than 60% of YLD was contributed by those aged > or = 45 years old who accounted for about a third of total population in both sexes. Gini index was 0.666 of Dangtu County and 0.451 of Hanshou County, and 60% of YLD was contributed by the highly endemic villages.
  
  
  CONCLUSIONS
  The concentration index and Gini index could quantify the magnitude of health inequalities well. The priority of morbidity control should be given to those aged > or = 45 years old and living in highly endemic villages.
