Secular, socioeconomic and urban-rural gradients and geographical differences in beef and fat consumption within the United States of America are compared with corresponding data on colorectal cancer incidence and mortality rates. These results, together with the results of most previous epidemiological studies, appear to contradict the hypothesis that beef and fat consumption are involved in the aetiology of colorectal cancer.
将美国牛肉和脂肪消费的长期、社会经济及城乡梯度差异和地理差异,与结直肠癌发病率和死亡率的相应数据进行了比较。这些结果,连同大多数先前流行病学研究的结果,似乎与牛肉和脂肪消费参与结直肠癌病因学的假设相矛盾。
