Vaccination coverage against human papilloma virus (HPV) in the United States remains low. This study aimed to identify factors associated with initiation of HPV vaccination among young women and girls in New Orleans, Louisiana. The study was conducted in Pediatrics and Obstetrics & Gynecology clinics in New Orleans between 2014 and 2017. Surveys were administered to women ages 18 through 26, and guardians of girls ages 12 through 17. Demographics, health history, sources of medical information, knowledge of HPV and HPV vaccination, opinions on vaccination, expected support for vaccination, and systems-level barriers were assessed. Participants self-reported discussion of the vaccine with a healthcare provider, and whether they or their child had been vaccinated. Participants were predominantly black and low-income. Among young adults, 61/121 (50%) had received any doses of the HPV vaccine; 71/94 (75%) of girls had received it (p < 0.01). In both groups, knowledge of the HPV vaccine, believing the vaccine was available from their usual healthcare provider, and having discussed the vaccine with their provider were associated with increased odds of vaccination. Among young adults, additional factors associated with vaccination were younger age, distance from a healthcare center, knowledge of HPV, and expectation of support from parents. Among guardians, holding negative views on vaccination was associated with decreased odds of vaccination. Discussion of the vaccine with a healthcare provider was the factor most strongly associated with initiation of HPV vaccination in both groups. The results provided actionable items to increase HPV vaccination uptake in these populations.
