Background: An association between cancer survival and socioeconomic status (SES) has been evaluated for many different cancers but calculating socioeconomic inequality in survival is very lake. In this study we aimed to determine associations between socioeconomic inequality and survival risk factors in patients with gastric carcinoma (GC).
Methods: In this cross-sectional study, we enrolled 235 patients with confirmed of GC. SES data were retrieved from three sources pathological records, official death certificates and telephone interviews. polychoric correlation matrix was used to reduce the number of variables. Inequality measured by concentration index (CI) and we decomposing CI to determine contribution in inequality. All analysis was performed by standard statistical software, STATA (Version 11.2).
Results: The overall CI for late diagnosis (2 stage onwards) and positive history of smoking were -0.020 (95% CI = -0.041– 0.004) and -0.105 (95% CI = -0.110– -0.076), respectively. Results of decomposition shows past medical history of gastrointestinal diseases (29%) and history of smoking (18%) have a largest contribution in inequality in GC survival.
Conclusion: Results of this study showed risk factors in GC survival such as smoking, having a past medical history of gastrointestinal diseases and late diagnosis is more prevalent among people of lower SES.
