Project description:OBJECTIVE:To increase our understanding about the health beliefs of African-American parents and their daughters toward HPV infection and HPV vaccine acceptance. METHODS:The Health Belief Model was used as a guiding framework. Principles of grounded theory, theoretical sampling, and constant comparison analysis were used to qualitatively analyze data generated from personal interviews of African-American parents (n = 30) and their 12- to 17-year-old daughters (n = 34). RESULTS:Mothers and daughters perceived low susceptibility to HPV infection and perceived the HPV vaccine as beneficial in protecting against genital warts and cervical cancer. Compared to daughters, parents placed particular emphasis on the vaccine's protection against genital warts. A major HPV vaccine acceptance barrier among parents and daughters was the politicization of the HPV vaccine by government figures. In addition, concerns about unknown side effects, safety, and effectiveness of HPV vaccination emerged. Cues to action varied among parents and daughters, and self-efficacy was higher among parents than daughters. CONCLUSION:Understanding the health beliefs that promote HPV vaccine acceptance, while identifying and addressing beliefs that are barriers among parents and daughters, will assist in the development of appropriate HPV vaccine promotion initiatives for African-American parents and daughters.

Project description:IntroductionVaccinating children against COVID-19 protects children's health and can mitigate the spread of the virus to other community members.ObjectiveThe primary objective of this study was to use a socio-ecological perspective to identify multi-level factors associated with US parents' intention to vaccinate their children.MethodsThis study used a longitudinal online cohort. Multinomial logistic regression models assessed socio-ecological predictors of negative and uncertain child COVID-19 vaccination intentions compared to positive intentions.ResultsIn June 2021, 297 parents were surveyed and 44% reported that they intended to vaccinate their children while 25% expressed uncertainty and 31% did not intend to vaccinate their children. The likelihood of reporting uncertain or negative intention, compared to positive intention to vaccinate their children was higher among parents who had not received a COVID-19 vaccination and those who did not have trusted information sources. Parents who talked to others at least weekly about the COVID-19 vaccine were less likely to endorse uncertain compared to positive vaccine intentions (aRRR: 0.44; 95% CI: 0.20-0.93). A sub-analysis identified that parents had significantly higher odds of intending to vaccinate older children compared to younger children (children ages 16-17 years v. 0-4 years OR: 2.01, 95% CI: 1.05-3.84). An additional sub-analysis assessed the stability of parents' intention to vaccinate their children between March 2021 and June 2021 (N=166). There was transition within each intention group between the study periods; however, symmetry and marginal homogeneity test results indicated that the shift was not statistically significant. Parents expressing uncertainty in March 2021 were the most likely to change their intention, with 24% transitioning to positive intention and 23% to negative intention in June 2021.ConclusionStudy findings suggest that programs to promote vaccination uptake should be dyadic and work to promote child and parent vaccination. Peer diffusion strategies may be particularly effective at promoting child vaccination uptake among parents expressing uncertainty.

Project description:Head and neck cancer (HNC) is the fifth most common malignancy worldwide with an annual mortality rate of 200,000. About 90% of HNC can be classified as head and neck squamous cell carcinomas (HNSCC), of which approximately 75% are attributed to alcohol and tobacco consumption and 25% are associated with human papillomavirus (HPV), predominantly HPV16. HPV-associated OPC have better prognosis and a more favorable response to therapy as compared to HPV-negative tumors. Differences in risk factors, age of presentation, clinical behavior and gene expression profiles indicate that HPV-positive and HPV-negative tumors develop via different molecular mechanisms and are biologically distinct. African American (AA) males have a higher incidence of HNC than any other racial/gender group, and a mortality rate almost three-fold that observed in European American (EA) males. Overall, AA patients tend to present with more HPV-negative OPC and have worse prognosis as compared to both HPV-positive and HPV-negative HNSCC in EA patients. Despite the unveiling of differential gene expression patterns, genetic and epigenetic profiles and the compilation of a mutational landscape along with preliminary TCGA data of HPV-related and unrelated HNC, the molecular determinants of the racial disparity in HNC are yet to be identified. This study aimed to compare the gene expression profiles of HPV-negative HNSCC from AA and EA patients, and determine their biological differences.

Project description:Numerous national guidelines now include primary human papillomavirus (HPV) testing as a recommended screening option for cervical cancer in the United States yet little is known regarding screening intentions for this specific screening strategy or interventions that may increase uptake. Gain- and loss-framed messaging can positively impact health behaviors; however, there is mixed evidence on which is more effective for cervical cancer screening, with no published evidence examining HPV testing. To help address this gap, this study compared the effects of message framing on screening knowledge and intentions related to primary HPV testing. We randomized females aged 21-65 (n = 365) to receive brief messaging about cervical cancer screening with either gain- or loss-framing. In January-February 2020, participants completed pretest and posttest measures evaluating cervical cancer knowledge, beliefs, and intentions to be screened using HPV testing. We used generalized estimating equations to model message and framing effects on screening outcomes, controlling for age, education, race, and baseline measures. In comparison to pretest, messaging significantly increased HPV-related screening intentions [adjusted OR (aOR): 2.4 (1-3.5)] and knowledge [aOR: 1.7 (1.2-2.4)], perceived effectiveness of HPV testing [aOR: 4.3 (2.8-6.5)], and preference for primary HPV screening [aOR: 3.2 (1.2-8.5)], regardless of message framing. For all outcomes, no significant interaction by message framing was observed. Brief public health messaging positively impacted HPV-related screening intentions, knowledge, and beliefs, independent of message framing. In conjunction with other strategies, these results suggest that messaging could be an effective tool to increase uptake of primary HPV testing. PREVENTION RELEVANCE: Primary HPV tests are more sensitive and offer greater reassurance than Pap tests alone yet use for routine cervical cancer screening remains low. Brief public health messaging can positively impact awareness, knowledge, and screening intention regarding primary HPV testing. Messaging campaigns paired with other strategies can increase uptake across populations.See related Spotlight, p. 823.

Project description:OBJECTIVE:Pictorial warnings on cigarette packs increase motivation to quit smoking. We sought to examine the potential mediating role of negative affect, message reactance (ie, an oppositional reaction to a message) and perceived risk in shaping quit intentions. METHODS:In 2014 and 2015, we randomly assigned 2149 adult US smokers to receive either pictorial warnings or text-only warnings applied to their cigarette packs for 4?weeks. Analyses used structural equation modelling with bootstrapped SEs to test our theorised mediational model. FINDINGS:Pictorial warnings increased negative affect, message reactance and quit intentions (all P<0.001), but not perceived risk (ie, perceived likelihood and severity of harms of smoking). Negative affect mediated the impact of pictorial warnings on quit intentions (mediated effect=0.16, P<0.001). Message reactance weakened the impact of pictorial warnings on quit intentions, although the effect was small (mediated effect=-0.04, P<0.001). Although pictorial warnings did not directly influence perceived risk, the model showed additional small mediation effects on quit intentions through negative affect and its positive association with perceived risk (mediated effect=0.02, P<0.001), as well as reactance and its negative association with perceived risk (mediated effect=-0.01, P<0.001). CONCLUSIONS:Pictorial cigarette pack warnings increased quit intentions by increasing negative affect. Message reactance partially attenuated this increase in intentions. The opposing associations of negative affect and reactance on perceived risk may explain why pictorial warnings did not lead to observable changes in perceived risk.

Project description:Exposure to pro-vaccination messages from nonmedical peers and others perceived to share a similar value system for society (referred to as worldview outlook) improves vaccination attitudes. Nonetheless, a minority of African American parents have friends and family members who provide them with vaccine advice. The aims of the current study were to identify the presumed worldview outlook of eight types of community figures as perceived by African American parents, and determine parents' trust in these figures for vaccine advice, and whether trust varied according to the figures' racial concordance. A cross-sectional survey was administered to 110 African American parents in 2015. Parents perceived the community figures to represent a spectrum of worldview outlooks. Although levels of trust in the community figures differed overall (p < .001), it was high in the school nurse, pediatrician, mother, father, disease survivor, and vaccine scientist. All trusted figures except the father were perceived to hold a communitarian outlook. Parents shown race-concordant figures had higher levels of trust in them than those who were shown race-discordant equivalents (p < .01). These findings suggest that vaccination campaigns geared toward African American parents may be strengthened by including other nonmedical, African American spokespersons who convey their community contributions in messages.

Project description:Human papillomavirus (HPV) infects nearly 85% of sexually active Americans during their lifetime, causing most cervical and five other cancers. Routine HPV vaccination is recommended for adolescents to prevent HPV-attributable cancers, but HPV vaccination coverage remains low, especially in Tennessee. In 2021, 54.6% of the population in Shelby County, Tennessee was Black or African American, reporting higher rates of new cervical cancer cases than other counties in Tennessee. While medical and public health professionals (HPs) play a critical role in promoting vaccination coverage, little is known about the factors HPs perceive to influence HPV vaccination for this population. This study sought to explore HPs' perceived facilitators and barriers of HPV vaccination among African American adolescents. Qualitative individual interviews with 26 HPs in Shelby County were conducted between October 2019 and February 2020. Interpretive content analysis of the interview data guided by the socio-ecological model revealed several important themes regarding the facilitators and barriers across the individual, interpersonal, and community levels. At the individual level, parental vaccine hesitancy emerged as a leading barrier to HPV vaccination, while appropriate education facilitated the vaccination. At the interpersonal level, a lack of strong provider recommendations impeded HPV vaccination, whereas improved communication skills with patients facilitated the vaccination. Finally, the community-level barriers included a lack of education and social/religious norms; the community-level facilitators included community outreach efforts. HPs should consider development of comprehensive community-based approaches that leverage the facilitators and barriers at multiple levels to increase HPV vaccination among African American adolescents in this region.

Project description:Background: Asthma is highly heterogeneous and severity evaluation is key to asthma management. DNA methylation (DNAm) contributes to asthma pathogenesis. This study aimed to identify nasal epithelial DNAm differences between severe and non-severe asthmatic children and evaluate the impact of environmental exposures. Methods: Thirty-three non-severe and 22 severe asthmatic African-American children were included in an epigenome-wide association study. Genome-wide nasal epithelial DNAm and gene expression were measured. CpG sites associated with asthma severity and environmental exposures and predictive of severe asthma were identified. DNAm was correlated with gene expression. Enrichment for transcription factor (TF) binding sites or histone modifications surrounding DNAm differences were determined. Results: We identified 816 differentially methylated CpG positions (DMPs) and 10 differentially methylated regions (DMRs) associated with asthma severity. Three DMPs exhibited discriminatory ability for severe asthma. Intriguingly, six DMPs were simultaneously associated with asthma, allergic asthma, total IgE, environmental IgE, and FeNO in an independent cohort of children. 27 DMPs were associated with traffic-related air pollution or secondhand smoke. DNAm at 22 DMPs were altered by diesel particles or allergen in human bronchial epithelial cells. DNAm levels at 39 DMPs were correlated with mRNA expression. Proximal to 816 DMPs, three histone marks and several TFs involved in asthma pathogenesis were enriched. Conclusions: Significant differences in nasal epithelial DNAm were observed between non-severe and severe asthma in African-American children, a subset of which may be useful to predict disease severity. These CpG sites are subject to the influences of environmental exposures and may regulate gene expression.
