Background:Colon cancer (CC) is a significant public health concern. With Asian Americans (AAs) representing a rapidly growing demographic in the United States, our study examined CC prevalence among AAs.Methods:The study merged the 2017–2021 Medical Expenditure Panel Survey and County Health Ranking. Our analysis calculated age-adjusted CC rates and examined its prevalence across states. Regression analyses were conducted to study county-level risk factors of CC.Results:The CC age-adjusted rate among AAs increased by five-fold, from 155 per 100,000 in 2017 to 753 per 100,000 in 2021. State-level disparities revealed the highest CC prevalence in Arkansas, Rhode Island, and New Hampshire. Not speaking other languages and having insurance were significantly associated with higher CC rates, suggesting barriers to preventions and greater use of screening (p< 0.05). County-level analysis identified lower CC prevalence in regions with a greater socioeconomic advantage (p< 0.05). Socioeconomic advantage seemed to facilitate higher screening rates, which then translated into higher CC rates.Conclusions:Our findings underscore the need for early preventions to address rising CC rates among AAs. Future research should also explore geographic factors to better understand the disparities in CC risk.
背景：结肠癌是重要的公共卫生问题。随着亚裔美国人成为美国增长最快的人口群体，本研究旨在探讨该人群结肠癌患病情况。 方法：本研究整合了2017-2021年医疗支出面板调查与县健康排名数据。通过计算年龄标准化结肠癌发病率，分析各州患病差异，并采用回归模型探究县级风险因素。 结果：亚裔美国人年龄标准化结肠癌发病率从2017年的10万分之155增至2021年的10万分之753，增长达五倍。州级差异显示阿肯色州、罗德岛州和新罕布什尔州患病率最高。仅使用英语交流与拥有医疗保险者结肠癌发病率显著升高（p<0.05），提示预防措施存在障碍及筛查利用率提升。县级分析发现社会经济优势地区结肠癌患病率较低（p<0.05），社会经济优势可能通过提高筛查率间接导致检出率上升。 结论：研究结果强调需通过早期预防应对亚裔美国人结肠癌发病率上升趋势。未来研究应进一步探索地理因素对结肠癌风险差异的影响机制。
