INTRODUCTION: Human papillomavirus (HPV) ranks as the most prevalent sexually transmitted infection globally, with a significant association with cervical cancer in cervix-having individuals. Understanding the epidemiological patterns of HPV vaccination rates and behaviors within the context of sexual and gender minority (SGM) women is essential in identifying factors hindering the initiation of HPV vaccination and screening. METHODS: A systematic review was conducted by searching five databases (PubMed, CINAHL, Embase, Web of Sciences, MedLine). Eligibility criteria included the following: reported HPV vaccination or screening outcomes, conducted among SGM women, data collected since 2010. All studies were independently screened and synthesized following PRISMA guidelines. Of 44 items, 13 studies met the criteria. RESULTS: Sexual and gender minority women reported substantial HPV vaccine hesitancy and decreased screening practices compared to their non-SGM peers, with the degree of vaccine hesitancy and delayed screening varying among bisexual, lesbian, and transgender individuals. Individual factors associated with HPV vaccine hesitancy and decreased screening include socioeconomic status, vaccination awareness, and SGM identity. Meanwhile, interpersonal and structural factors include community biases, family support, lack of provider LGBTQ+ health education, and structural racism. CONCLUSION: Sexual and gender minority women experience a substantial health care disparity surrounding HPV vaccination hesitancy and screening status. Results from this study substantiate the need for the standardization of health care practice, individual patient vaccine counseling, and the expansion of sexual and gender minority health training at all tiers of medical education. Furthermore, additional disaggregated research is needed to understand the unique health circumstances of bisexual, lesbian, and transgender individuals, as the current research landscape fails to capture the community’s health needs.
