The aim of this cross-sectional survey was to assess awareness, knowledge, and attitudes in regard to human papillomavirus (HPV) and vaccination against HPV among college students. From 2015 to 2017, 386 diverse undergraduates were recruited from a south Florida university. A survey, part of which was researcher developed, of HPV awareness, knowledge, and attitudes was conducted. The majority (84%) of participants had heard of HPV, and 70% had favorable attitudes toward vaccination. Only 28% of men and 55% of women had received ≥1 dose vaccine ( p = .01), and 4% of all participants reported that they had received 3 doses. Those with ≥1 dose ( n = 123, 40.1%) were more knowledgeable about HPV ( p = .01). High knowledge scores were recorded for 30% of respondents and were strongly associated with HPV vaccine initiation among both men and women ( p < .001) and perceived knowledge among women only ( p < .001). Negative attitudes toward HPV vaccine acceptance were associated with low knowledge scores ( p = .01) and undervaccination ( p < .001). Vaccinated women ( n = 95) were over seven times more likely than were unvaccinated women ( n = 115) to report positive vaccine attitudes (relative risk = 7.1). HPV vaccination status was not associated with vaccine attitudes among men. HPV knowledge and vaccine uptake remain problematic among college students, and deficits in both are associated with negative HPV vaccine attitudes. Although the knowledge gap is narrowing, HPV vaccination efforts should target young men, as HPV-related cancer morbidity continues to rise in men.
Parent hesitancy contributes to reduced HPV vaccination rates. The HPVcancerfree app (HPVCF) was designed to assist parents in making evidence-based decisions regarding HPV vaccination. This study examined if parents of vaccine-eligible youth (11–12 yrs.) who use HPVCF in addition to usual care demonstrate significantly more positive intentions and attitudes toward HPV vaccination and greater HPV vaccination rates compared to those not using HPVCF. Clinics (n = 51) within a large urban pediatric network were randomly assigned to treatment (HPVCF + usual care) or comparison (usual care only) conditions in a RCT conducted between September 2017 and February 2019. Parents completed baseline and 5-month follow-up surveys. Participant-level analysis determined 1) change in HPV vaccination initiation behavior and related psychosocial determinants and 2) predictors of HPV vaccine initiation. Parents (n = 375) who completed baseline and 5-month follow-up surveys were female (95.2%), 40.8 (±5.8) yrs. married (83.7%), employed (68.3%), college educated (61.9%), and privately insured (76.5%). Between-group analysis of HPVCF efficacy demonstrated that parents assigned to receive HPVCF significantly increased knowledge about HPV and HPV vaccination ( p < .05). Parents who accessed content within HPVCF significantly increased knowledge about HPV & HPV vaccine ( p < .01) and perceived effectiveness of HPV vaccine ( p < .05). Change in HPV vaccine initiation was not significant. A multivariate model to describe predictors of HPV vaccine initiation demonstrated an association with Tdap and MCV vaccination adoption, positive change in perceived effectiveness of the HPV vaccine, and reduction in perceived barriers against HPV vaccination. HPVCF appears to be a feasible adjunct to the education received in usual care visits and reinforces the value of apps to support the important persuasive voice of the health-care provider in overcoming parent HPV vaccine hesitancy.
Purpose: To make baseline comparisons and evaluate the efficacy of an intervention designed to improve human papillomavirus (HPV) and HPV vaccine awareness, knowledge, and attitudes among ethnically diverse participants. Methods: Design: Pre- and post-intervention surveys. Setting: An urban, Hispanic-Serving South Florida university. Subjects: Three hundred eighty-seven diverse college students attending a gender studies course. Intervention: Students received a brief educational message designed to improve HPV-related knowledge and attitudes. Baseline and follow-up survey data were collected. Measures: Outcome measures included baseline and follow-up awareness of HPV, perceived knowledge of HPV and HPV vaccination, measured knowledge score, vaccine attitudes, and doses of HPV vaccine received. Analysis: Chi-square, analysis of covariance (ANCOVA), and Wilcoxon rank-sum tests were used to compare baseline differences and evaluate the efficacy of the intervention. Results: Hispanic participants had more positive attitudes toward HPV vaccination (62% vs. 44%, p =0.009) and were more willing to become vaccinated (66% vs. 46%, p =0.02) than non-Hispanic participants at baseline. Hispanic women (48%) were more likely to have initiated HPV vaccination than Hispanic men (27%, p =0.006). At baseline, only 30% of participants scored ≥4/7 points in knowledge. Participants' HPV knowledge improved by 41% after the intervention, with no difference by ethnicity in the post-intervention score. Conclusion: The intervention was useful in improving HPV-related knowledge and attitudes among diverse college students. Future studies should examine barriers to vaccination among ethnic minorities.
Objectives To assess the safety, acceptability, and preliminary efficacy of a culturally-adapted disclosure intervention for perinatally HIV-infected combined antiretroviral therapy patients in Haiti and the Dominican Republic. Design A quasi-experimental trial was conducted comparing caregiver–youth pairs who completed the intervention [adapted Blasini disclosure model (aBDM)] to pairs who discontinued aBDM participation before disclosure. aBDM consists of five components: structured healthcare worker training; one-on one pre-disclosure intervention/education sessions for youth (describing pediatric chronic diseases including cancer, diabetes and HIV) and for caregivers (strengthening capacity for disclosure); a scheduled supportive disclosure session; and one-on-one postdisclosure support for caregivers and youth. Methods Caregivers of nondisclosed combined antiretroviral therapy patients aged 10.0–17.8 years were invited to participate. Data were collected by separate one-on-one face-to-face interviews of caregivers and youth by study staff and medical record review by pediatricians at enrollment and 3 months after disclosure or after intervention discontinuation. Results To date, 65 Dominican Republic and 27 Haiti caregiver–youth pairs have enrolled. At enrollment, only 46.4% of youth had viral suppression and 43.4% of caregivers had clinically significant depressive symptomatology. To date, two serious study-related adverse events have occurred. Seven of the 92 (7.6%, 6 in the Dominican Republic) enrolled pairs discontinued participation before disclosure and 39 had completed postdisclosure participation. Median plasma HIV-RNA concentration was lower in youth who completed aBDM than in youth who discontinued participation before aBDM disclosure (<40 versus 8673 copies/ml; P = 0.027). Completers expressed considerable satisfaction with aBDM. Conclusion Preliminary results suggest safety, acceptability, and possible effectiveness of the aBDM.
