大肠肿瘤与体力活动关系的病例对照研究

A Case-Control Study on the Relationship between Colorectal Neoplasm and Physical Activity

目的研究广东省惠州市大肠肿瘤与体力活动的关系,为制订本地区大肠肿瘤的预防措施提供科学依据。方法采用基于结肠镜检查的病例对照研究,应用Logistic回归对大肠肿瘤相关变量进行单因素和多因素分析。把可能的危险因素先行单因素分析,发现某些有意义的因素后,纳入Logistic回归模型进行多因素分析。结果体力活动与大肠癌不相关,轻度体力活动为大肠腺瘤的危险因素。结论惠州地区大肠腺瘤的发病与体力活动的强度相关,大肠癌的发病与体力活动不相关。

Objective To investigate the in Huizhou city, Guangdong province, providing better scientific basis for prevention of local colorectal neoplasm. Methods With a colonoscopy-based case-control study, Logistic regression model was used for univariate and multivariate analysis of colorectal neoplasm. Forward univariate analysis was used to select significant factors, then the data was brought into multivariate analysis of Logistic regression model. Results There weren＇t significant Relationship between colorectal cancer and physical activity, Mild physical activity was the risk factor of colorectal adenoma.
