title: [A case - control study of gallstone disease in female population in Taicang].
abstract: OBJECTIVE
  To investigate the risk factors of gallstone disease in female population in Taicang.
  
  
  METHODS
  A case - control study conducted on 144 cases and 371 controls aged 35 - 79 years in five villages. Diagnosis of gallstone disease was assessed by real - time ultrasonography. The case was considered as presence of gallstones at echograph and previous cholecytectomy. The controls were selected from a random sample of female participates.
  
  
  RESULTS
  Through univariate and multivariate analysis, gallstone disease was significantly associated with age (OR = 1.80), family history of gallstone disease (OR = 3.66), hypertension (OR = 1.93), fat intake (OR = 1.77), number of pregnancies (OR = 1.44) and menopause (OR = 1.67). Drinking water from deep well (OR = 0.54) was inversely associated with gallstone disease.
  
  
  CONCLUSIONS
  The main risk factors of female gallstone disease were age, family history of gallstone disease, fat intake, number of pregnancy and menopause. Drinking water from deep well was a protective factor of gallstone disease.
