Breast, cervical, and colorectal cancer screening test use in the US territories of Guam, Puerto Rico, and the US Virgin Islands.

BACKGROUND: The United States Preventive Services Task Force (USPSTF) recommends breast, cervical, and colorectal cancer screening among eligible adults, but information on screening use in the US territories is limited. METHODS: To estimate the proportion of adults up-to-date with breast, cervical, and colorectal cancer screening based on USPSTF recommendations, we analyzed Behavioral Risk Factor Surveillance System data from 2016, 2018, and 2020 for the 50 US states and DC (US) and US territories of Guam and Puerto Rico and from 2016 for the US Virgin Islands. Age-standardized weighted proportions for up-to-date cancer screening were examined overall and by select characteristics for each jurisdiction. RESULTS: Overall, 67.2% (95% CI: 60.6-73.3) of women aged 50-74 years in the US Virgin Islands, 74.8% (70.9-78.3) in Guam, 83.4% (81.7-84.9) in Puerto Rico, and 78.3% (77.9-78.6) in the US were up-to-date with breast cancer screening. For cervical cancer screening, 71.1% (67.6-74.3) of women aged 21-65 years in Guam, 81.3% (74.6-86.5) in the US Virgin Islands, 83.0% (81.7-84.3) in Puerto Rico, and 84.5% (84.3-84.8) in the US were up-to-date. For colorectal cancer screening, 45.2% (40.0-50.5) of adults aged 50-75 years in the US Virgin Islands, 47.3% (43.6-51.0) in Guam, 61.2% (59.5-62.8) in Puerto Rico, and 69.0% (68.7-69.3) in the US were up-to-date. Adults without health care coverage reported low test use for all three cancers in all jurisdictions. In most jurisdictions, test use was lower among adults with less than a high school degree and an annual household income of < $25,000. CONCLUSION: Cancer screening test use varied between the US territories, highlighting the importance of understanding and addressing territory-specific barriers. Test use was lower among groups without health care coverage and with lower income and education levels, suggesting the need for targeted evidence-based interventions.
