Disparities in parental human papillomavirus (HPV) vaccine awareness and uptake among adolescents

Trends in HPV vaccine awareness among parents of adolescent girls and boys (ages 13-17) and HPV vaccine uptake (≥1 dose) among girls (ages 13-17) were evaluated in Los Angeles County, California. Between 2007 and 2011, parental HPV vaccine awareness increased from 72% to 77% overall, with significant increases among mothers, Latinos, and respondents with daughters and Medi-Cal insured children. In 2011, parents who were male, older, less educated, Asian/Pacific Islander, and had sons remained significantly less likely to be aware. HPV vaccine initiation among daughters nearly doubled from 25% in 2007 to 48% in 2011, and girls who were older, uninsured, and had access-related barriers showed the largest improvements. In 2011, daughters who were younger and who had older and African American parents were at risk for low uptake. Thus, initiatives targeting male and younger adolescents, culturally-relevant information, and access to vaccination may help to reduce identified disparities.
