目的探讨不同来源膳食纤维和钙摄入与结直肠癌致病之间的关系。方法选择洛阳中心医院于2012年1月-2015年1月收治的118例洛阳地区结直肠癌患者作为观察组,另从医院同期参加健康体检的人群中随机选取98例作为对照组。以问卷调查的方式对以上两组患者的饮食中膳食纤维的来源以及钙的摄入量情况进行调查,比较组间差异。结果在膳食纤维的摄入方面,对照组的蔬菜纤维摄人量明显高于其他各组(P<0.05);直肠癌以及右半结肠癌患者的水果纤维摄入量明显低于对照组(P<0.05);各组的谷类膳食纤维含量无统计学意义差异(P>0.05)。在钙的摄入量方面,对照组动物性钙的摄入量明显高于右半结肠癌患者(P<0.05)。结论膳食纤维来源与摄人量的不同对结直肠癌的发病率有着不同的影响,蔬菜膳食纤维可以有效降低结直肠癌的发病率。膳食钙对结直肠癌发病率的影响与膳食结构有较大关系。
Objective To investigate the relationship between different sources of dietary fiber and calcium intake and the pathogenesis of colorectal cancer. Methods 118 cases of colorectal cancer patients in Luoyang district from January 2012 to January 2015 in Luoyang Central Hospital were selected as the observation group and 98 cases were randomly selected as the control group from the crowd in the same period of health checkup in the hospital. A questionnaire survey was conducted to investigate the sources of dietary fiber and dietary intake of calcium in the above two groups of patients, and the differences among groups were compared. Results In the dietary fiber intake, the vegetable fiber intake of the control group was significantly higher than the other groups (P <0.05); the intake of fruit fiber in patients with rectal cancer and right colon cancer was significantly lower than that of the control group (P <0.05). The content of cereal dietary fiber in each group had no significant difference (P> 0.05). In terms of calcium intake, animal calcium intake was significantly higher in the control group than in patients with right-sided colon cancer (P <0.05). Conclusion The different sources of dietary fiber and intake have different effects on the incidence of colorectal cancer. Vegetable dietary fiber can effectively reduce the incidence of colorectal cancer. Dietary calcium on the incidence of colorectal cancer and diet have a greater relationship.
