Gastric cancer (GC), one of the most common cancer worldwide, remains the third leading cause of cancer-related mortality. The etiology of GC may arise from genetic and environmental factors. This study aimed to determine the association between GC incidence and socioeconomic status in Iran.
An ecological study was designed to investigate the relationship between socioeconomic factors and the risk of GC incidence. The data of socioeconomic variables such as income changes, unemployment rate, urbanization ratio, inflation rate, and air pollution changes in 31 provinces were collected from the Statistical Center of Iran, and the data of GC of 31 provinces were provided from the Iranian National Population-based Cancer Registry (INPCR). Data from 2014 to 2017 was analyzed using panel data analysis, the fixed effects model by EViews software.
Panel data model was suitable for the present study. Results showed that there was a positive and significant relationship between GC incidence and socioeconomic factors including income changes (≤ 0.001), unemployment rate (≤0.01), inflation rate (≤ 0.05), and air pollution changes (≤ 0.001). The urbanization ratio showed a negative relationship and was not statistically associated with GC incidence (> 0.05).
Our findings suggest a positive and significant association between socioeconomic status and GC incidence, proposing a GC risk factor. The key public health policies and welfare policies' priority should therefore be to schedule for the GC management.
胃癌是全球最常见的癌症之一，仍然是癌症相关死亡的第三大主要原因。胃癌的病因可能源于遗传和环境因素。本研究旨在确定伊朗胃癌发病率与社会经济地位之间的关联。
设计了一项生态学研究，以调查社会经济因素与胃癌发病风险之间的关系。从伊朗统计中心收集了31个省份的社会经济变量数据，如收入变化、失业率、城市化率、通货膨胀率和空气污染变化，31个省份的胃癌数据由伊朗国家人口癌症登记处（INPCR）提供。使用面板数据分析，通过EViews软件的固定效应模型分析2014年至2017年的数据。
面板数据模型适用于本研究。结果表明，胃癌发病率与社会经济因素之间存在正相关且显著的关系，这些因素包括收入变化（≤0.001）、失业率（≤0.01）、通货膨胀率（≤0.05）和空气污染变化（≤0.001）。城市化率呈负相关，与胃癌发病率无统计学关联（>0.05）。
我们的研究结果表明社会经济地位与胃癌发病率之间存在正相关且显著的关联，提出了一个胃癌风险因素。因此，关键的公共卫生政策和福利政策的重点应该是安排胃癌管理。
