| English Abstract: |
A case-control study was conducted among 250 persons suffering from cancer of the colon and rectum (CRC) in the urban area of Beijing from Jan 1, 1988-June 30, 1989 to explore the risk factors for CRC.500 neighbour residents were matched as Control.
The chi-square test and Conditional Logistic Regression analysis show that high consumption of meat, oil, low occupational physical activity and psychological stress were risk factors of CRC.A trend of increased odds ratio (OR) of CRC with high meat intake and a trend of decreased OR with increased occupational physical activity were found. The high consumption of vegetables and the habit of eating uncooked fresh vegetables showed a protective effect on CRC.
The results of the study support the CRC etiological hypotheses of "fat-bile acid action" and "deficiency of dietary fibres". |
