Abstract:
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.
