title: [A case-control study on the risk factors of esophageal cancer in Jieyang City of Guangdong in China].
abstract: OBJECTIVE
  To study the risk factors of esophageal cancer in Jieyang city of Guangdong province.
  
  
  METHODS
  Two hundred and fourteen cases with pathological diagnosis of esophageal cancer were recruited at Jieyang Municipal People's Hospital in 1999. Two hundred and fourteen controls were selected from healthy residents matched with sex, age and residential places (town) of the cases. All cases and controls had resided in Jieyang city for over 20 years and were studied through a uniformed questionnaire. Non-conditional logistic regression was used for multivariate analysis.
  
  
  RESULTS
  The important risk factors were over-hot tea drinking habit (OR:1.39-3.74), fast eating (OR:1.54-4.10), animal oil (OR:3.57-42.03) and meat consumption (OR:1.36-5.05) while the protective factors were tap water (OR:0.13-0.51) drinking habil for over 20 years. Histories of smoking and family esophageal cancer were not significantly correlated with esophageal cancer.
  
  
  CONCLUSIONS
  The risk factors revealed in this study were commonly exposed to the residents of Jieyang city. Most of the factors were in agreement to the results from other similar studies, but the factors of animal oil and meat were unique in this study, which called for further studies.
