Abstract

Objectives

We conducted a longitudinal study to examine human papillomavirus (HPV) vaccine uptake among male adolescents and to identify vaccination predictors.

Methods

In fall 2010 and 2011, a national sample of parents with sons aged 11 to 17 years (n = 327) and their sons (n = 228) completed online surveys. We used logistic regression to identify predictors of HPV vaccination that occurred between baseline and follow-up.

Results

Only 2% of sons had received any doses of HPV vaccine at baseline, with an increase to 8% by follow-up. About 55% of parents who had ever received a doctor’s recommendation to get their sons HPV vaccine did vaccinate between baseline and follow-up, compared with only 1% of parents without a recommendation. Fathers (odds ratio = 0.29; 95% confidence interval = 0.09, 0.80) and non-Hispanic White parents (odds ratio = 0.29; 95% confidence interval = 0.11, 0.76) were less likely to have vaccinated sons. Willingness to get sons HPV vaccine decreased from baseline to follow-up among parents (P < .001) and sons (P = .003).

Conclusions

Vaccination against HPV remained low in our study and willingness to vaccinate may be decreasing. Physician recommendation and education about HPV vaccine for males may be key strategies for improving vaccination.
