Abstract:
Objective To compare the risk factors of breast cancer in Ningxia Hui and Han women,and to provide evidence for the prevention and control of breast cancer.Methods The female patients of breast cancer treated at the Affiliated Hospital of Ningxia Medical University between May 2013 and July 2014 were chosen for case study,while other patients treated at the same hospital and during the same period who did not have breast cancer were selected as a control. An epidemiological survey was conducted using the same questionnaire among the two groups.The survey involved general demographic information,menstrual history,reproductive history,life habit and family history of cancer.Risk factors of breast cancer in Hui and Han nationalities were analyzed by logistic regression analysis.Results Logistic regression analysis showed that the abortion number(OR =2.631,P =0.028)was a risk factor for the occurrence of breast cancer in women of the Hui nationality,while physical exercise (OR =0.177,P =0.040)was a protective factor.Tumor suffered by immediate family members (OR =4.249,P =0.014),abortion number (OR =1.602,P =0.001 ),the age of the first childbirth (OR =1.253,P =0.001 )and the age of first marriage(OR =1.223,P =0.001 )were the major risk factors while physical exercise (OR =0.422,P =0.001 )was a protective factor against breast cancer in Han nationality. Conclusion The risk factors of breast cancer in the women of Hui and Han nationalities are consistent in terms of the total number of abortions and physical exercise.Compared with the Hui people,the age of first marriage,the age of first child birth,and tumor suffered by immediate family members also play a role in the occurrence of breast cancer in the Han na-tionality.
