背景：不健康的食物环境可能与患饮食相关癌症（如结直肠癌）的风险较高有关。我们进行了一项生态分析，以评估当地食品环境与结直肠癌发病率之间的关系，并分别针对男性和女性进行了评估。方法：利用德克萨斯州癌症登记处的数据对2005年至2015年期间诊断出结直肠癌的40岁及以上个人进行地理编码到他们的住宅2010年人口普查区域。从2005年的商业模式调查中检索到的机构分类为有限服务餐馆的总数，每个人口普查区使用人行横道地图邮政编码的人口普查区。人口普查区不健康食品供应量的计算方法是，将每个人口普查区的有限服务餐馆机构估计数除以人口普查区人口，并分为四分位数。结果：调整人口普查区水平的社会人口学特征后，不健康食物可获得性四分位数2的结直肠癌发病率略高（发生率比（IRR）= 1.03，95% CI：1.00-1.05），但不是第3个四分位数（IRR = 1.02，95% CI：1.00-1.05）和四分位数4（最高供应率，IRR = 1.02，95% CI：0.99-1.05）与不健康食品供应率最低的人口普查区相比。结直肠癌的发病率与人口普查区的不健康食品供应量较高没有密切关系。未来应进行观察性研究，以检查建筑环境对结直肠癌风险的影响。
Background: Unhealthy food environments may be associated with higher risks of developing diet-related cancers, such as, colorectal cancer. We conducted an ecological analysis to evaluate the relationship between the local food environment and colorectal cancer incidence overall and separately for males and females.Methods: Data from the Texas Cancer Registry was utilized to geocode individuals aged 40 years and older diagnosed with colorectal cancer from 2005 to 2015 to their residential 2010 census tract. Total number of establishments classified as Limited Service Restaurants for each census tract was retrieved from the 2005 Business Patterns Survey by using a crosswalk to map zip codes to census tract. Census tract unhealthy food availability was calculated by dividing the estimated number of Limited Service Restaurant establishments in each census tract by the census tract population and divided into quartiles. Generalized estimating equations were used to assess the association between unhealthy food availability quartiles and colorectal cancer incidence.Results: Adjusting for the census tract level sociodemographic characteristics, the incidence of colorectal cancer was slightly higher in unhealthy food availability quartile 2 (Incidence Rate Ratio (IRR) = 1.03, 95 % CI: 1.00-1.05), but not quartile 3 (IRR = 1.02, 95 % CI: 1.00-1.05), and quartile 4 (highest availability, IRR = 1.02, 95 % CI: 0.99-1.05) compared to census tracts with lowest unhealthy food availability.Conclusion: Colorectal cancer incidence was not strongly associated with census tracts with higher unhealthy food availability. Future observational studies should be conducted to examine the influence of the built environment on colorectal cancer risk.
