Declining awareness of HPV and HPV vaccine within the general US population.

ABSTRACT: Programs aimed at boosting human papillomavirus (HPV)-related awareness are considered one of the most effective strategies for increasing vaccination uptake and eliminating HPV-associated cancers. Several US states have made strong commitments to this effort through legislation and dedicated funds. However, it is not known if these efforts have resulted in population-level increments in HPV awareness overtime. Using the Health Information National Trends Survey data, we examined the awareness of HPV and HPV vaccine in the US, between 2008 and 2018. Prevalence estimates and confidence intervals were calculated for HPV and HPV vaccine awareness. Further, we assessed awareness after stratifying by key sociodemographic characteristics. Overall, the awareness of HPV and HPV vaccine declined over time. The lowest awareness was among racial minorities, rural residents, male respondents, those aged 65 years and older, as well as those with the lowest educational and socioeconomic standing. Between 2013 and 2018, the awareness of HPV and HPV vaccine declined by almost 10% among males, those with a high school level of education or lower, and those who earned less than USD 35,000 per annum. In 2018, the awareness of HPV and HPV vaccine was highest among non-Hispanic whites (65.8% and 66.5%) and female adults (70.5% and 71.4%); however, these figures represented declines of about 5% from rates observed in 2008. Amidst a background of sub-optimal HPV vaccination uptake and a growing incidence of HPV-associated cancers in the US, HPV-related awareness within the general US population has declined over time. This calls for stricter enforcement of legislation aimed at boosting HPV awareness, as well as frequent evaluation of government-funded HPV awareness programs.

Project description:Rationale & Objective:Data from patients in one delivery system have suggested that the prevalence of chronic kidney disease (CKD) awareness differs by how the question is asked. We examined the sensitivity and specificity of different CKD awareness questions among diverse community-dwelling adults who were not necessarily engaged in primary care to determine the generalizability of prior results. Study Design:Cross-sectional study. Setting & Participants:Participants in the Healthy Aging in Neighborhoods of Diversity Across the Life Span (HANDLS) Study. Predictor:CKD awareness, ascertained using 5 different questions. Outcome:Sensitivity and specificity of each awareness question, using laboratory results as the gold standard. Analytic Approach:Logistic regression was used to compare sensitivities of different awareness questions. Results:Among 2,046 participants, mean (SD) age was 56.5 (9.1) years, 41.5% were men, and 61.3% were African American. More than 40% were poor, 35% reported not having health insurance, and 16.9% had low health literacy. More than 20% (n = 424) had CKD. Sensitivities of single CKD awareness questions ranged from 2.2% for "kidney damage" to 5.2% for "kidney problem." Sensitivity of the compound question asking about "weak kidneys, failing kidneys, or kidney disease" was 19.5%. Sensitivity of this compound CKD awareness question was higher among study participants with more advanced CKD and low health literacy, and those who lived below the poverty level. Limitations:Single measures of estimated glomerular filtration rate and albuminuria; study participants may have been more engaged in their health care than the average US adult, potentially limiting the generalizability of results. Conclusions:CKD awareness is low among community-dwelling adults with kidney disease, though data using a sensitive compound question ascertaining awareness suggest that we have met the Healthy People 2020 goal related to CKD awareness of 13.4%. Understanding the phrases about kidney disease that are most understandable to patients with and at risk for CKD is important to further increase CKD awareness.

Project description:ObjectivesWe assessed the knowledge and awareness of cervical cancer, HPV and HPV vaccine, and willingness and acceptability to vaccinate in sub-Saharan African (SSA) countries. We further identified countries that fulfill the two GAVI Alliance eligibility criteria to support nationwide HPV vaccination.MethodsWe conducted a systematic review of peer-reviewed studies on the knowledge and awareness of cervical cancer, HPV and HPV vaccine, and willingness and acceptability to vaccinate. Trends in Diphtheria-tetanus-pertussis (DTP3) vaccine coverage in SSA countries from 1990-2011 were extracted from the World Health Organization database.FindingsThe review revealed high levels of willingness and acceptability of HPV vaccine but low levels of knowledge and awareness of cervical cancer, HPV or HPV vaccine. We identified only six countries to have met the two GAVI Alliance requirements for supporting introduction of HPV vaccine: 1) the ability to deliver multi-dose vaccines for no less than 50% of the target vaccination cohort in an average size district, and 2) achieving over 70% coverage of DTP3 vaccine nationally. From 2008 through 2011 all SSA countries, with the exception of Mauritania and Nigeria, have reached or maintained DTP3 coverage at 70% or above.ConclusionThere is an urgent need for more education to inform the public about HPV, HPV vaccine, and cervical cancer, particularly to key demographics, (adolescents, parents and healthcare professionals), to leverage high levels of willingness and acceptability of HPV vaccine towards successful implementation of HPV vaccination programs. There is unpreparedness in most SSA countries to roll out national HPV vaccination as per the GAVI Alliance eligibility criteria for supporting introduction of the vaccine. In countries that have met 70% DTP3 coverage, pilot programs need to be rolled out to identify the best practice and strategies for delivering HPV vaccines to adolescents and also to qualify for GAVI Alliance support.
