Effect of the decision-making process in the family on HPV vaccination rates among adolescents 9-17 years of age.

The purpose of this study was to examine the relationship between human papillomavirus (HPV) vaccine uptake among adolescents aged 9-17 years and the decision-making process used by families in determining whether to vaccinate their children against HPV. A cross-sectional sample of women with at least one child aged 9-17 years (n = 1256) was recruited from 3 reproductive health clinics in Southeast Texas during 2011-2013. Self-administered survey included questions about the HPV vaccination decision-making process, HPV vaccine uptake (initiation and 3-dose series completion), and demographics. Among mothers with at least one 9 to 17-year-old daughter (n = 783), 40% independently decided whether or not to vaccinate their daughter against HPV, 22% involved their husbands/partners, and 31% their daughters. Only 7% of respondents reported other formats in the decision-making (husband/partner alone or daughter alone). Similarly, for women with at least one eligible son (n = 759), 39% decided alone, 30% with their husbands/partners, 24% with their sons, and 7% reported other formats. Among mothers with a daughter, those who made the decision independently were more likely to report that their daughters had initiated the HPV vaccine series (30%) compared with women who included their husbands/partners (10%) or daughters (20%) in the decision process or stated other types (18%) of decision making (P < 0.001). The respective figures for the completion of the entire series among daughters were 16%, 6%, 11%, and 11% (P = 0.012). Among mothers with a son, a similar scenario was observed for vaccine initiation (17%, 4%, 10%, and 0%, respectively) (P < 0.001) and completion (7%, 1%, 4%, and 0%, respectively) (P = 0.003). These associations remained significant after adjusting for confounder variables. Awareness programs to increase HPV vaccine uptake should include both parents and children, as all have an important role in deciding whether or not children will be vaccinated.
