Abstract
Cancer screenings in Louisiana (LA) have been consistently lower than the national average. Sexual and gender minorities (SGM) are more likely to be non-compliant with cancer screening guidelines and consistently do not meet cancer screening recommendations. This study compares compliance to cervical, breast, and colorectal cancer (CRC) screening guidelines over time between SGM and the non-SGM population in LA. Data were obtained from the LA 2014, 2016, 2018, 2020, and 2022 Behavioral Risk Factor Surveillance System (BRFSS). The sample was divided into gay (including lesbian, gay, bisexual, or other sexual orientation other than straight) and straight. Three primary outcomes of interest were used to measure breast, cervical, and CRC cancer screening adherence based on the U.S. Preventive Services Task Force (USPSTF) screening recommendation at the time of each survey. Descriptive analysis and chi-square tests were conducted using sample weights. CRC had the lowest compliance rate in the entire population and across sexual orientation groups. Twenty-five percent of both populations had never received any CRC screening test. Comparatively, 3.6% of straight and 5.3% of gay populations had never received a mammogram while 6.6% of straight and 13.6% of the population had never received a pap smear. Significant improvements in compliance to breast, cervical, and CRC cancer screenings guidelines was observed among those who identified as straight over the survey years until 2020. Decreases in screening compliance were observed in this population from 2020 to 2022, likely due to the effects of the COVID pandemic. Screening compliance in those who identified as gay showed more variation over time in all three cancers. Screening compliance for CRC and cervical cancer were at its highest in 2016, declined to its lowest point in 2020, but increased in 2022. In 2016, there was a significant decline in breast cancer screening compliance in this population to the lowest ever observed in both groups. The initial increases in colorectal and cervical cancer screening observed from 2014 to 2016 among the gay population may be attributed to significant decreases in uninsured rates following the passage of the Affordable Care Act. Additionally, this population saw increased access to the private insurance market following the Obergefell decision and the Marriage Equality Act of 2015, which extended employer-sponsored coverage to same-sex couples. While breast cancer screenings declined from 2014-2016 in the gay population, there was a sharp increase from 2016 to 2018, which aligns with the 2016 expansion of Medicaid in Louisiana. Despite increases in access to insurance coverage, SGM individuals report being in fair or poor health and having negative experiences with healthcare providers at higher rates than their non-SGM counterparts. More research is needed to understand the healthcare landscape and experiences of SGM Louisianans. This will help to inform targeted interventions to increase screenings and improve cancer outcomes among this population.
