目的研究回族人群独特的饮食习惯与胃癌患病的相关性,并进一步探讨与回族人群胃癌发病相关的饮食危险因素。方法采用1︰1配对的病例对照研究方法,问卷调查126例胃癌和贲门癌回族患者以及126例非病例回族人群的饮食习惯,采用单因素和多因素条件Logistic回归模型进行数据分析。结果经单因素与多因素条件Logistic回归分析结果显示,三餐不定时、常食腌制食品、常食油炸食品均有统计学意义(P﹤0.05,OR值分别为3.054,2.363,1.915)。常食水果可降低胃癌的发生(OR=0.281,P﹤0.01)。结论三餐不定时、常食腌制食品及常食油炸食品可能会增加回族人群胃癌患病的危险性,而多食水果是回族胃癌的保护因素。
Objective To study the association between the unique dietary habits of Hui nationality and the prevalence of gastric cancer, and to further explore the dietary risk factors associated with the incidence of gastric cancer in the Hui population. Methods A case-control study with 1: 1 matching was used to investigate the dietary habits of 126 cases of Hui and 126 cases of gastric cancer and cardia cancer and 126 cases of non-Hui ethnicity. Data were analyzed by Logistic regression model with one-factor and multi-factor conditions. Results The results of univariate and multivariate conditional Logistic regression analysis showed that when meals were irregular, there was significant difference between the regular foods and the fried foods (P <0.05, OR = 3.054, 2.363, 1.915 respectively). Eat fruits can reduce the incidence of gastric cancer (OR = 0.281, P <0.01). Conclusion Irregular meals, regular pickled foods and fried foods may increase the risk of gastric cancer in Hui population, and eat more fruits are the protective factors of gastric cancer in Hui.
