Determination of effective factors on geographic distribution of the incidence of colorectal cancer in Tehran using geographically weighted Poisson regression model.

摘要: Background: This study aimed to determine effective factors on geographic distribution of the Incidence Colorectal Cancer (CRC) in Tehran, Iran using Geographically Weighted Poisson Regression Model. Methods: ecological was carried out at neighborhood level Tehran 2017-2018. Data for CRC incidence extracted from population-based cancer registry data Iran. The socioeconomic variables, risk and health costs were Urban HEART Study Tehran. weighted regression model used determination association between these variables with incidence. GWR 4, Stata 14 ArcGIS 10.3 software systems statistical analysis. Results: total number incident cases 2815 2008 2011, whom, 2491 successfully geocoded neighborhood. median IRR local : unemployed people over 15 year old (median IRR: 1.17), women aged 17 years or older university education head household 1.06), without insurance coverage 1.10), households daily consumption milk 0.85), smoking 1.07), household's expenditure 1.39), disease diagnosis 1.03), medicines 1.05), cost hospital 1.09), medical visits 1.27). Conclusion: spatial variability observed most that had effects Spatial is necessary when interpreting results utterly helpful implementation prevention programs.
