Introduction
Changes in up-to-date cervical cancer screening (CCS) over time by sexual orientation and race/ethnicity were estimated to identify trends in screening disparities.
Methods
This 2024 retrospective, cross-sectional analysis of National Health Interview Survey data (years 2013, 2015, 2019 and 2021) included 40,818 cisgender women aged 21–65 without hysterectomy. Joinpoint analysis was performed to calculate the annual percent change (APC) of up-to-date CCS from 2013 to 2021. Logistic regression (years 2019 and 2021) was used to describe the relationship between up-to-date screening and sexual orientation, race/ethnicity, and the interaction thereof.
Results
The adjusted odds of up-to-date CCS were 22 % lower for lesbian, gay, and/or bisexual (LGB) compared to heterosexual women (OR = 0.78, p = 0.01). Up-to-date CCS fell significantly from 80.50 % in 2013 to 75.00 % in 2021 for heterosexual respondents (APC = -0.97 %, p < 0.01), but was stable across years for LGB respondents. Up-to-date CCS decreased for Hispanic (APC = -1.52, p < 01) and non-Hispanic White only heterosexual women (APC = -0.63, p = 0.02). It also decreased for non-Hispanic Black/African American only LGB women (APC = -2.67, p < 0.01) falling from 85.22 % in 2013 to 67.91 % in 2021. By multiplicative interaction, LGB Hispanic women were more up-to-date than their heterosexual counterparts (p = 0.05).
Conclusions
In 2021 there were approximately 19.72 million women aged 21–65 who were not up-to-date with CCS. 1.76 million LGB women were not up-to-date for CCS, and a greater proportion of these women identified as non-Hispanic Black/African American. CCS must be improved for all cisgender women, and specific attention should be given to those who identify as LGB and/or Black/African American.
