Analysis on heritability and risk factors of eastern resident in Inner Mongolia

  Objective   To determine the affection degree of heritability and incidence risk factors of esophageal carcinoma in the eastern inner Mongolia area.

  Methods   The heredity epidemiology method and case-control study were performed.

  Results   The heritability of the first degree relative of esophageal carcinoma was(38.9±9.5)%.The risk factors for esophageal carcinoma included:time limit of drinking liquor(OR=5.408 1, 95% CI=3.892 7~6.792 1).time limit of smoking(OR=2.815 9, 95% CI=2.267 1~3.126 7), melena(OR=9.172 4, 95% CI=7.786 0~10.896 3)psycho-stimulatory history(OR=6.601 5, 95% CI=5.027 4~7.216 4)less-develop factor(OR=4.793 2, 95% CI=3.136 2~5.723 3).

  Conclusion   There was family assemblage in esophageal carcinoma obviously.There was correlative relation between esophageal carcinoma and bad habit and negative living events in the eastern inner Mong olia area.
