Little is known about cancer-screening practices of various Asian subgroups, and even less is known about factors that may predict screening in these populations.
Two independent surveys were conducted with 218 Filipino and 229 Korean female immigrants, aged 50 years and older, residing in Los Angeles.
In these convenience samples, 48% of Filipino and 41% of Korean women reported receipt of a Pap smear within the past 2 years; 41% of Filipino and 25% of Korean women reported receipt of a mammogram and a clinical breast exam within the past 2 years; and 25% of Filipino and 38% of Korean women reported colorectal cancer screening (blood stool test within the past 12 months or sigmoidoscopy/colonoscopy within the past 5 years). Only 14% of Filipino and 10% of Korean women were adherent to cancer-screening guidelines for all three sites. These differences in screening rates were statistically significant in multivariate analyses of the combined sample, controlling for all demographic characteristics, including age, percent of lifetime in the United States, education, marital status, health insurance, employment, and ethnicity. The two variables that were most consistently independently associated with adherence to cancer screening in both samples were higher percentage of lifetime spent in the United States and ever having had a checkup when no symptoms were present.
These two variables-percent of lifetime in the United States and ever having had a checkup when no symptoms were present-can alert a physician that cancer-screening tests may be overdue among Korean and Filipino immigrants in the United States. Future research should identify predictors of cancer screening among other Asian immigrant groups and U.S.-born Asian women to assist in targeting intervention efforts.
对于亚洲不同亚群体的癌症筛查行为知之甚少，而对于这些人群中可能预测筛查行为的因素了解更少。
对居住在洛杉矶的218名年龄在50岁及以上的菲律宾女性移民和229名韩国女性移民进行了两项独立调查。
在这些便利样本中，48%的菲律宾女性和41%的韩国女性报告在过去两年内接受过巴氏涂片检查；41%的菲律宾女性和25%的韩国女性报告在过去两年内接受过乳房X光检查和临床乳房检查；25%的菲律宾女性和38%的韩国女性报告进行过结肠直肠癌筛查（在过去12个月内进行过大便潜血检查或在过去5年内进行过乙状结肠镜检查/结肠镜检查）。只有14%的菲律宾女性和10%的韩国女性遵守了所有三个部位的癌症筛查指南。在对合并样本进行的多变量分析中，控制了所有人口统计学特征，包括年龄、在美国生活的时间百分比、教育程度、婚姻状况、医疗保险、就业情况和种族后，这些筛查率的差异具有统计学意义。在两个样本中，与坚持癌症筛查最一致且独立相关的两个变量是在美国生活的时间百分比更高以及在无症状时曾进行过体检。
这两个变量——在美国生活的时间百分比以及在无症状时曾进行过体检——可以提醒医生，在美国的韩国和菲律宾移民中，癌症筛查测试可能已逾期。未来的研究应确定其他亚洲移民群体和美国出生的亚洲女性中癌症筛查的预测因素，以协助确定干预工作的目标。
