Health Care-Related Correlates of Cervical Cancer Screening among Sexual Minority Women: An Integrative Review.

INTRODUCTION: Sexual minority women (SMW; lesbian, bisexual, nonheterosexual women) may have lower rates of cervical cancer screening than heterosexual women. Health care-related factors may explain some of the variation in cervical cancer screening rates among SMW. We aimed to synthesize published evidence of health care-related correlates of cervical cancer screening among SMW.

METHODS: We searched PubMed, CINAHL, and PsycINFO databases for English-language studies published between January 2000 and March 2017 that 1) assessed sexual identity or the sexual partners of female participants, 2) included cervical cancer screening as a main outcome of interest, and 3) measured at least one health care-related variable in addition to cervical cancer screening. We excluded articles that 1) reported on non-US samples or 2) did not report original research. We reviewed the sample, methods, and findings of 17 studies. We then summarized current knowledge about health care-related factors across 3 categories and generated recommendations for clinical practice and future research.

RESULTS: Several health care-related factors such as previous contraception use, having a primary care provider, knowledge of screening recommendations, and disclosing sexual orientation to providers were consistently positively associated with cervical cancer screening. Three groups of factors-previous health care use, health care provider-related factors, and belief-related factors-account for a substantial part of the variation in cervical cancer screening among SMW.

DISCUSSION: Several gaps in knowledge remain that could be addressed by recruiting more diverse samples of SMW with improved generalizability. Clinicians and clinical institutions can address factors associated with low rates of screening among SMW by preventing sexual orientation-based discrimination, inviting sexual orientation disclosure, and offering cervical cancer screening to SMW at a variety of health care encounters. Future research should examine how the location of care and health care provider type affect SMW's cervical cancer screening behaviors and should test the effectiveness of health care interventions designed to address sexual orientation-related disparities.
