Studies have found that women are less likely than men to undergo colorectal cancer (CRC) screening. While one source of these disparities may be gender differences in barriers and facilitators to screening, another may be differences in reporting bias.
In this study of 345 male and female veterans, conducted in 2006 in Minneapolis, MN, we examined CRC screening adherence rates by gender using medical records and self-report and assessed whether any differences were due to reporting bias.
We found a significantly higher rate of colonoscopy use among men when using self-report data, but no significant differences in either overall or test-specific screening adherence when using medical record data. Analyses examining the prevalence and determinants of concordance between self-report and medical records screening revealed that compared to women, men were less accurate in reporting sigmoidoscopy and colonoscopy and over-reported screening by colonoscopy. Men were also more likely to have missing self-report data and how missing data were handled affected differences in screening behavior. Accuracy in screening behavior was not explained by demographic variables, good physical or mental health, or physician recommendation for screening.
Reported gender disparities in CRC screening adherence may be a result of reporting bias.
研究发现，女性进行结直肠癌（CRC）筛查的可能性低于男性。这些差异的一个来源可能是筛查障碍和促进因素方面的性别差异，另一个来源可能是报告偏倚的差异。
本研究对明尼苏达州明尼阿波利斯市的 345 名男性和女性退伍军人进行了研究，使用医疗记录和自我报告检查了性别对 CRC 筛查依从性的影响，并评估了任何差异是否归因于报告偏倚。
我们发现，使用自我报告数据时，男性结肠镜检查使用率显著更高，但使用医疗记录数据时，总体或特定检查的筛查依从性没有显著差异。分析自我报告和医疗记录筛查之间一致性的流行率和决定因素表明，与女性相比，男性在报告乙状结肠镜检查和结肠镜检查时准确性较低，并且对结肠镜检查的筛查过度报告。男性也更有可能出现自我报告数据缺失，以及如何处理缺失数据会影响筛查行为的差异。筛查行为的准确性不能用人口统计学变量、良好的身心健康或医生推荐的筛查来解释。
报告的 CRC 筛查依从性方面的性别差异可能是报告偏倚的结果。
