157. Influence of Parent Sources of Information About Influenza Vaccine on Adolescent Vaccine Receipt

HPV DNA testing was performed by the Roche Linear Array, which identifies 37 HPV types. Data from participants who had not received an HPV vaccine (N1⁄4841) were pooled for analysis. Descriptive analyses were performed to define overall (at least 1 HPV type) and type-specific (HPV 16/18) detection. Univariable analyses (using chi square and Wilcoxon rank-sum tests) were performed to examine whether race, ethnicity, and other factors were associated with a) overall and type-specific HPV detection among all participants, and b) type-specific HPV detection among HPV-infected participants. Results: The mean age of participants was 19.3 years; 64.4% were Black and 8.9% Hispanic. Among all participants, at least one HPV type was detected in 73.0% of Black, 62.5% of White, and 63.0% of other women (p1⁄4.007), and in 69.9% of Hispanic and 68.7% of nonHispanic women (p1⁄4.83). HPV 16/18 was detected in 22.1% of Black, 18.8% of White, and 21.9% of other women (p1⁄4.55), and in 17.8% of Hispanic and 21.1% of non-Hispanic women (p1⁄4.51). Among HPV-infected participants, HPV 16/18 was detected in 30.3% of Black, 30.0% of White, and 34.8% of other women (p1⁄4.81), and in 25.5% of Hispanic and 30.7% of non-Hispanic women (p1⁄4.44) Among all participants, number of male sex partners in the previous 3 months was associated with HPV 16/18 positivity (p1⁄4.01), and among HPV-infected participants, knowledge about HPV and HPV vaccines was associated with HPV 16/18 positivity (p1⁄4.046). Conclusions: Although Black women had higher rates of HPV overall, the detection of HPV 16/18 did not differ by race or ethnicity among all women and among HPV-infected women. These findings are in contrast to those of recent studies suggesting that cervical precancers may be more likely to be caused by types other than HPV 16/18 in Black compared to White women, raising the question of whether susceptibility to the oncogenic potential of specific HPV types may differ by race.
