RESUMO

This study investigated the influences of mother-daughter communication and social media on mothers' HPV vaccine refusal for their daughters aged 9-17. A cross-sectional online survey among 11,728 mothers of girls aged 9-17 in Shenzhen, China was implemented between July and October 2023. Multi-level logistic regression models were fitted. Among 11,728 participants, 43.2% refused to have their daughters receive an HPV vaccination. In multivariate analysis, more openness in the mother-daughter communication (AOR: 0.99, 95%CI: 0.98, 0.99), perceived more positive outcomes of mother-daughter communication (AOR: 0.77, 95%CI: 0.75, 0.79), higher frequency of exposure to testimonials about daughters' HPV vaccination (AOR: 0.81, 95%CI: 0.78, 0.85) and information encouraging parents to vaccinate their daughters against HPV on social media (AOR: 0.76, 95%CI: 0.73, 0.79), and thoughtful consideration of the veracity of the information specific to HPV vaccines (AOR: 0.80, 95%CI: 0.77, 0.83) were associated with lower vaccine refusal. Mothers who were not the main decision-makers of daughters' HPV vaccination (AOR: 1.28 to 1.46), negative outcome expectancies of mother-daughter communication (AOR: 1.06, 95%CI: 1.04, 1.08), and mothers' HPV vaccine refusal (AOR: 2.81, 95%CI: 2.58, 3.06) were associated with higher vaccine refusal for their daughters. The level of mothers' HPV vaccine refusal for their daughters was high in China. Openness and outcome expectancies of mother-daughter communication and information exposure on social media were considered key determinants of HPV vaccine refusal for daughters. Future HPV vaccination programs should consider these interpersonal factors.

RESUMO

The Son of Sevenless 1 (SOS1) guanine nucleotide exchange factor, prevalent across eukaryotic species, plays a pivotal role in facilitating the attachment of RAS protein to GTP, thereby regulating the activation of intracellular RAS proteins. This regulation is part of a feedback mechanism involving SOS1, which allows both activators and inhibitors of SOS1 to exert control over downstream signaling pathways, demonstrating potential anti-tumor effects. Predominantly, small molecule modulators that target SOS1 focus on a hydrophobic pocket within the CDC25 protein domain. The effectiveness of these modulators largely depends on their ability to interact with specific amino acids, notably Phe890 and Tyr884. This interaction is crucial for influencing the protein-protein interaction (PPI) between RAS and the catalytic domain of SOS1. Currently, most small molecule modulators targeting SOS1 are in the preclinical research phase, with a few advancing to clinical trials. This progression raises safety concerns, making the assurance of drug safety a primary consideration alongside the enhancement of efficacy in the development of SOS1 modulators. This review encapsulates recent advancements in the chemical categorization of SOS1 inhibitors and activators. It delves into the evolution of small molecule modulation targeting SOS1 and offers perspectives on the design of future generations of selective SOS1 small molecule modulators.

RESUMO

BACKGROUND: Cervical cancer is the eighth most prevalent cancer among women nationwide, with 358 new cases reported annually. One of the strategies to prevent it is getting vaccinated against the human papillomavirus (HPV), the leading cause of this cancer. METHODS: A survey-based cross-sectional study was conducted in Riyadh, Saudi Arabia, to evaluate the acceptance of the HPV vaccine among parents of daughters and their knowledge of three domains: cervical cancer, HPV, and the HPV vaccine. RESULTS: 390 parents participated in the study, with 88.2% female, 39.74% of the participants aged between 36-62 years old, and 62.56% holding a bachelor's degree or above. Parents were more aware of cervical cancer (78.97%), followed by HPV (50%) and the HPV vaccine (41.28%). Awareness levels about cervical cancer were significantly different among males and females, while awareness of HPV and the HPV vaccine was significantly associated with parents' education levels. For instance, parents with a bachelor's degree or higher (54.9%) demonstrated greater awareness of HPV compared to parents with a high school diploma (41.9%) or a middle school diploma or less (41.5%). The overall participants' knowledge scores in all three domains were poor, with an average below 50%. 60% of parents believed their daughters should receive the HPV vaccine. CONCLUSION: More than half of the study participants are willing to vaccinate their daughters with the HPV vaccine despite their poor knowledge of the assessed domains. Awareness levels of HPV and the HPV vaccine are associated with education levels. We believe raising awareness among parents is necessary to improve the acceptance level of the HPV vaccine.

RESUMO

OBJECTIVES: Human papillomavirus (HPV) stands as one of the prevalent sexually transmitted infections (STIs) and serves as the primary factor behind nearly all instances of cervical cancer, along with various other non-cancerous conditions like genital warts. Our objective was to explore the knowledge and beliefs of Greek parents regarding HPV infection and the vaccination of boys against HPV. METHODS: A cross-sectional study took place at a university hospital located in the Peloponnese region of Greece, from January to June 2021. The study employed convenience sampling as its methodology, and data gathering involved the distribution of self-administered questionnaires to parents who had at least one son between the ages of 9 and 18 years. RESULTS: The final sample consisted of 120 individuals. 65.8 % of parents have been informed about HPV vaccination, knew that the HPV vaccine provides immunity against genital warts (50 %), and that minimum of two doses is necessary (46.7 %). 30.8 % intended to vaccinate their boys against HPV if the vaccine were available for males. The most important reasons for vaccination were the perception that both genders share equal responsibility in the prevention of sexually transmitted infections (91.7 %) and the protection against cancer (87.6 %), whereas the fear of adverse reactions and the adequate knowledge about HPV-related diseases were most reported as reasons of the intentions to not vaccinate their sons with 31.7 % and 25.8 % respectively. CONCLUSIONS: Although parents participating in the study know about HPV, however, there are significant lack of knowledge regarding HPV infection and the vaccine effects, which can significantly affect the acceptance of vaccination for boys.

RESUMO

BACKGROUND: To understand the dynamics that limit use of risk-management options by women at high risk of breast cancer, there is a critical need for research that focuses on patient perspectives. Prior research has left important gaps: exclusion of high-risk women not in risk-related clinical care, exclusion of non-white populations, and lack of attention to the decision-making processes that underlie risk-management choices. Our objective was to create a more inclusive dataset to facilitate research to address disparities related to decision making for breast cancer risk management. METHODS: The Daughter Sister Mother Project survey collects comprehensive information about the experiences of women at high risk of breast cancer. We collected novel measures of feelings about and reactions to cancer screenings; knowledge, barriers, and facilitators of risk-management options; beliefs related to cancer risk and risk management; and involvement with loved ones who had cancer. Eligible individuals were non-Hispanic white and non-Hispanic Black adult women who self-identified as having high risk of breast cancer and had no personal history of cancer. Between October 2018 and August 2019, 1053 respondents completed the online survey. Of these, 717 were confirmed through risk prediction modeling to have a lifetime breast cancer risk of ≥ 20%. Sociodemographic characteristics of this sample were compared to those of nationally representative samples of the US population: the 2019 Health Information National Trends Survey and the Pew Research Center report: Jewish Americans in 2020. RESULTS: The sample of 717 women at objectively high risk of breast cancer was largely (95%) recruited from non-clinical sources. Of these respondents, only 31% had seen a genetic counselor, 34% had had genetic testing specific to breast cancer risk, and 35% had seen at least one breast or cancer care specialist. The sample includes 35% Black respondents and 8% with Ashkenazi Jewish ancestry. Although encompassing a substantial range of ages, incomes, and education levels, respondents are overall somewhat younger, higher-income, and more educated than the US population as a whole. CONCLUSIONS: The DSM dataset offers comprehensive data from a community-based, diverse sample of women at high risk of breast cancer. The dataset includes substantial proportions of Black and Ashkenazi Jewish women and women who are not already in clinical care related to their breast cancer risk. This sample will facilitate future studies of risk-management behaviors among women who are and are not receiving high-risk care, and of variations in risk-management experiences across race and ethnicity.

RESUMO

BACKGROUND: Human papillomavirus (HPV) vaccines are offered free of charge in Finland to 10-12-year-old children. Nationally about 80% of girls are vaccinated, with regional differences in first dose coverage varying from 62% to 82% in girls born in 2011. This study examined the factors associated with HPV vaccination intention. Furthermore, we assessed the realisation of HPV vaccination among the daughters of the participating parents. METHODS: A web-based survey was conducted for randomly selected parents of girls (N = 6 465) aged 10 to 14 years of age. Data was collected in February and March 2022 in five Finnish high and low coverage municipalities. The national vaccination register was employed to assess realisation of vaccination. RESULTS: Participation rate was 13.7% (n = 883 parents). Almost all parents were aware of the association between HPV and cervical cancer, but only one fifth was aware of other diseases associated with HPV. Adherence to the national vaccination programme, parents' mother tongue, and trusting in official information were associated with positive vaccination intention. The most often reported reason for non-vaccination was fear of adverse effects (22%). Overall, parental attitudes towards HPV vaccination were positive, with 83% of parents indicating their daughter had received or will receive the vaccination. Vaccination realisation was subsequently examined and 88% of the daughters were vaccinated. CONCLUSIONS: Despite low knowledge of HPV-related diseases overall, majority of parents held a positive intention to vaccinate their daughter. Realisation of intention was high in our study, higher than the national uptake. Foreign-origin parents had lower intention to vaccinate their daughters. As information on HPV and its vaccine is available in 11 languages, there is a need to re-think accessibility. In-depth interviews are needed to better explore the reasons behind non-vaccination.

RESUMO

INTRODUCTION: Management of cystic echinococcosis (CE) requires knowledge of certain aspects related to the survival of Echinococcus granulosus. The viability of daughter vesicles (DV) is a determining factor in guiding therapeutic indications, particularly for transiently active Cysts type CE3b. PURPOSE: To determine the predictive factors of DV viability and its impact on the therapeutic management of CE3b type. MATERIALS AND METHODS: This is a prospective pilot study with an analytical aim on patients with cystic echinococcosis of the liver type CE2 and CE3b, operated in the General Surgery Department of Habib-Bourguiba Academic Hospital, Sfax-Tunisia for 22 months from March 2018 until December 2019. The unit of the study is the DV. A parasitological study of the DV was done in the parasitology laboratory. RESULTS: During the study period, 27 (40.9%) of 66 operated CE Disease from 21 patients containing 248 DV were explored. The median viability of DV protoscoleces was 16.7%. In bivariate analysis, factors for viability of DV protoscoleces were: fever, acute cholangitis, hyperbilirubinemia, left liver location, rock water and bilious echinococcal fluid (EF), cyst size ≥ 43 mm, Intracystic pressure ≥ 35 mmHg, DV size ≥ 6.5 mm, volume, number of DV/cyst ≥ 5, and opaque wall (p < 0.05). Predictive factors for the Non-viability of DV were: CE3b type, purulent EF, gelatinous EF. In multivariate analysis, only CE2 type, cyst size ≥ 43 mm, number of DV/cyst ≥ 5 and DV size ≥ 6.5 mm were factors significantly associated with the viability of DV protoscoleces. CONCLUSION: CE3b cysts without the criteria of viability of DV protoscoleces may become candidates for the 'Wait-and-Watch' procedure.

RESUMO

OBJECTIVES: Cervical cancer accounts for 10 percent of cancer deaths among women in India. The human papillomavirus (HPV) vaccine can protect against infection but it is not included in India's universal immunisation programme. This study aimed to assess the demand and willingness to pay for the HPV vaccine among mothers of adolescent daughters. METHODS: We conducted a contingent valuation exercise involving a hospital-based cross-sectional study to assess the demand for an HPV vaccine among mothers of adolescent daughters, their willingness to pay and its determinants. Participants were recruited at a tertiary care civil hospital in the city of Gurgaon in North India, and data was collected from December 2018 to February 2019. A questionnaire was administered to obtain demographic and awareness indicators. Payment cards were used to elicit the willingness to pay amount. RESULTS: Out of 319 respondents, 79% were willing to pay for the vaccine. The mean maximum willingness to pay was INR 629 (USD 35), which was less than the vaccine market price of INR 2000-3000 (USD 117-175) per dose. Participant age and number of children significantly influenced demand, while family income and awareness of cervical cancer influenced willingness to pay for the HPV vaccine. Participants were willing to spend between 3% and 34% of their monthly income on the vaccine. CONCLUSIONS: High demand and low willingness to pay for the HPV vaccine indicate low value perception of the health outcome among mothers of adolescent children in India. A strategy aimed at a price reduction of the vaccine and increasing its demand through improved awareness is important. At the same time, subsidising the vaccine in the short run is needed.

RESUMO

Human papillomavirus (HPV) is the second most common cause of cancer worldwide among females. HPV vaccination is highly protective against HPV infection and can reduce 56% of HPV infections. Therefore, the study aims to assess mothers' intention to vaccinate their daughters aged 9-14 years old against human papillomavirus in Debre Tabor town, Northwest Ethiopia, using the theory of planned behavior. A community-based cross-sectional study design was employed using the theory of planned behavior from November 1 to 30, 2022, in Northwest Ethiopia. A total sample of 449 study participants was enrolled. The study participants were selected using a multi-stage random sampling technique. Data was collected using an interview-administered questionnaire. The data was entered into EPI data version 4.6 and then, exported to SPSS version 23 for analysis. Those variables with a p-value <.05 with 95% CI were considered significant predictors. Mothers' positive intention to vaccinate their daughters aged 9-14 years against HPV was 67.5%. Attitude, perceived behavioral control, and subjective norm were significant predictors with (AOR = 10.09, 95% CI = 6.23-16.32), (AOR = 4.12, 95% CI = 2.71-6.26), and (AOR = 16.397, 95% CI = 9.69-27.748), respectively. Only two-thirds of mothers have a positive intention to vaccinate their daughters against human papillomavirus. Attitude, perceived behavioral control, and subjective norm were predictors. Therefore, it is better to do community mobilization toward the advantage of HPV vaccination.

RESUMO

BACKGROUND: Cervical cancer, caused by the human papillomavirus (HPV), is the fourth most common cancer among women worldwide. Although many countries have introduced national HPV vaccination programs, many girls worldwide remain unprotected. As part of a demonstration project in 2016, the Indonesian government provided the HPV vaccination for free to all year five and six female students in Jakarta and several other cities, with a plan to roll out the program nationally in the future. Understanding parents' decision-making regarding whether they will allow their daughters to receive the HPV vaccine is important to ensure optimum uptake.

Methods: Twenty-four parents in Jakarta were interviewed. Data were analysed thematically using The Theory of Planned Behaviour constructs of attitudes, subjective norms and perceived behavioural control.

Result: Some parents had limited knowledge about cervical cancer and the HPV vaccine; others did not even realise that the free HPV vaccination program had been offered in their daughter's schools. Those who had better knowledge and positive attitudes trusted their health professionals as a source of information. Peer approval, trust in the government and having the vaccine through a school-based program was important for trust, eliminated cost barriers, and increased access.

Conclusion: Parents' attitudes towards cervical cancer and HPV vaccination are influenced in part by their knowledge. Shaping positive initial attitudes is important, as once formed, attitudes are often difficult to change. Our findings suggest that a free school-based vaccine accompanied by sufficient and non-ambiguous information from trusted sources is vital to uptake.

RESUMO

Kristen rat sarcoma (KRAS) is one of the most common oncogenes in human cancers. As a guanine nucleotide exchange factor, Son of Sevenless Homologue 1 (SOS1) represents a potential therapeutic concept for the treatment of KRAS-mutant cancers because of its activation on KRAS and downstream signaling pathways. In this review, we provide a comprehensive overview of the structure, biological function, and regulation of SOS1. We also focus on the recent advances in SOS1 inhibitors and emphasize their binding modes, structure-activity relationships and pharmacological activities. We hope that this publication can provide a comprehensive compendium on the rational design of SOS1 inhibitors.

RESUMO

Drk, a homologue of human GRB2 in Drosophila, receives signals from outside the cells through the interaction of its SH2 domain with the phospho-tyrosine residues in the intracellular regions of receptor tyrosine kinases (RTKs) such as Sevenless, and transduces the signals downstream through the association of its N- and C-terminal SH3 domains (Drk-NSH3 and Drk-CSH3, respectively) with proline-rich motifs (PRMs) in Son of Sevenless (Sos) or Daughter of Sevenless (Dos). Isolated Drk-NSH3 exhibits a conformational equilibrium between the folded and unfolded states, while Drk-CSH3 adopts only a folded confirmation. Drk interacts with PRMs of the PxxPxR motif in Sos and the PxxxRxxKP motif in Dos. Our previous study has shown that Drk-CSH3 can bind to Sos, but the interaction between Drk-NSH3 and Dos has not been investigated. To assess the affinities of both SH3 domains towards Sos and Dos, we conducted NMR titration experiments using peptides derived from Sos and Dos. Sos-S1 binds to Drk-NSH3 with the highest affinity, strongly suggesting that the Drk-Sos multivalent interaction is initiated by the binding of Sos-S1 and NSH3. Our results also revealed that the two Sos-derived PRMs clearly favour NSH3 for binding, whereas the two Dos-derived PRMs show almost similar affinity for NSH3 and CSH3. We have also performed docking simulations based on the chemical shift perturbations caused by the addition of Sos- and Dos-derived peptides. Finally, we discussed the various modes in the interactions of Drk with Sos/Dos.

RESUMO

Breast cancer (BC) is one of the most frequent cancer-related deaths in women worldwide. Studies have shown the potential impact of circRNAs in multiple human tumorigeneses. Research on the vital signaling pathways and therapeutic targets of circRNAs is indispensable. Here, we aimed to investigate the clinical implications and underlying mechanisms of circ_0042881 in BC. RT-qPCR validated circ_0042881 was notably elevated in BC tissues and plasma, and closely associated with BC clinicopathological features. Functionally, circ_0042881 significantly accelerated the proliferation, migration, and invasion of BC cells in vitro and tumor growth and metastasis in vivo. Mechanistically, circ_0042881 promoted BC progression by sponging miR-217 to relieve its inhibition effect in son of sevenless 1 (SOS1), which further activated RAS protein and initiated downstream signaling cascades, including MEK/ERK pathway and PI3K/AKT pathway. We also demonstrated that treatment of BAY-293, an inhibitor of SOS1 and RAS interaction, attenuated BC progression induced by circ_0042881 overexpression. Furthermore, Eukaryotic initiation factor 4A-III (EIF4A3) could facilitate circ_0042881 circularization. Altogether, we proposed a novel signaling network in which circ_0042881, induced by EIF4A3, influences the process of BC tumorigenesis and metastasis by miR-217/SOS1 axis.

RESUMO

BACKGROUND: Cancer is a rapidly rising cause of morbidity and mortality in sub-Saharan Africa. Cervical cancer, in particular, is still one of the leading causes of mortality for women in this setting. The uptake of healthcare services is in part influenced by patients' belief systems. We sought to better understand the perception of cancer in the Kom tribe of Northwest Cameroon. METHODS: A qualitative research study was completed using a semi-structured interview guide and one-on-one interviews with 45 parents of girls aged 9-14 years. These girls were candidates for free HPV vaccination to prevent cervical cancer. The interviews were recorded, transcribed, and analyzed using ATLAS.ti 9. RESULTS: Thirty-five mothers and ten fathers with a median age of 42 yo were interviewed from Mbingo, Belo, Njinikom, and Fundong. Half of the parents were farmers, with three being herbalists or traditional medicine doctors. Seventy-seven percent had either no or only primary school education. None had had cancer. All knew at least one person with cancer. The most common word for cancer in the Kom language is "ngoissu". It can refer to a bad infection or cancer. The occurrence of ngoissu is the result of either a curse placed on you, ancestral retribution, or transgressing the ngoulatta (snail shell spoken over and usually placed in a garden). The implications are that treatment of ngoissu must involve the traditional doctor who determines the spiritual issue and prescribes a remedy (like a herb or tea) and/or an incantation. Within the context of cancer, this can lead to a delay in diagnosis until the disease is no longer curable by conventional therapies. CONCLUSION: Ways to bridge biomedical healthcare services and traditional medicine are needed, especially in tribal contexts where the latter is an integral part of daily life.

RESUMO

OBJECTIVES: The etiology of testicular germ cell tumors (TGCT) is suspected to be related to prenatal environmental risk factors. Some solvents have potential endocrine disrupting or carcinogenic properties and may disrupt male genital development in utero. The aim of this study was to examine the association between parental occupational exposure to solvents and TGCT risk among their offspring. METHODS: A French nationwide case-control study, TESTIS included 454 TGCT cases and 670 controls frequency-matched on region and 5-year age strata. Participants were interviewed via telephone and provided information on parental occupations at birth. Job-exposure matrices (JEM) developed in the French Matgéné program were used to assign exposure to five petroleum-based solvents, five solvents or groups of oxygenated solvents, and five chlorinated solvents. Odds ratios (OR) for TGCT and 95% confidence intervals (CI) were estimated using conditional logistic regression, adjusting for TGCT risk factors. RESULTS: Occupational exposure to at least one solvent during the year of their son's birth was 41% among fathers and 21% among mothers. Paternal exposure to at least one solvent showed OR 0.89 (95% CI 0.68-1.15). Exposure to perchloroethylene (OR 1.41, 95% CI 0.55-3.61), methylene chloride (OR 1.13, 95% CI 0.54-2.34) and diesel/kerosene/fuel oil (OR 1.17, 95% CI 0.80-1.73) disclosed OR >1 but with low precision. Our results suggest a possible modest increase in non-seminoma risk for sons whose fathers were highly exposed to trichloroethylene (OR 1.44, 95% CI 0.79-2.63). Maternal exposure to at least one solvent showed OR 0.90 (95% CI 0.65-1.24). When stratifying by birth year, men born in the 1970s experienced an increased TGCT risk following maternal exposure to fuels and petroleum-based solvents (OR 2.74, 95% CI 1.11-6.76). CONCLUSION: Overall, no solid association was found between parental occupational exposure to solvents and TGCT risk. The association found with maternal occupational exposure to fuels and petroleum solvents among older men needs further investigation.

RESUMO

OBJECTIVES: We aimed to identify and compare the characteristics and factors associated with parental intention to vaccinate daughters under 12 years old against human papillomavirus (HPV), examining data from 2016 and 2020. METHODS: Data were obtained from the Korean National Cancer Screening Survey conducted in 2016 and 2020. The present study included 3,510 parents with daughters under 12 years old. Changes in parental intention-to-vaccinate rates were calculated. To identify factors associated with parental intention to vaccinate their daughters, the chi-square test and logistic regression analysis were used. RESULTS: The percentage of respondents intending to vaccinate their daughters increased from 33.4% in 2016 to 58.9% in 2020, constituting a 25.5 percentage point (%p) increase. Since 2016, the proportion of men expressing positive intention towards HPV vaccination increased by 31.5%p, while that of women demonstrated a 20.9%p increase. Logistic regression analysis indicated that parents with a strong intention to vaccinate their daughters tended to be younger, more educated, and aware of the free vaccination program available, as well as to have a history of HPV vaccination and to have undergone cervical cancer screening within 2 years, compared to those who did not intend to vaccinate. Being a mother with a history of HPV vaccination was the strongest predictor of positive intention to vaccinate a daughter. CONCLUSIONS: The intention among parents to vaccinate daughters remains relatively low, although it is rising. To increase the HPV vaccination rate, strong recommendations and education should be provided to parents and the younger generation.

RESUMO

Cadmium (Cd), is a well-known reproductive toxicant. The impacts of paternal Cd exposure on offspring glucose and lipid metabolism remain unclear, despite the abundance of adverse reports following early exposure from the mother. Here, we assessed paternally acquired metabolic derailment using a mouse model. LC-MS/MS, transcriptomics and molecular experimental techniques were subsequently applied in this study to explore the potential mechanism. We found that paternal Cd exposure caused glucose intolerance, lower insulin sensitivity and abnormal hepatic glycogen storage in adult female offspring, but not in males. LC-MS/MS data showed that hepatic phospholipids accumulation was also only observed in adult female offspring after paternal Cd exposure. Gene expression data showed that the level of insulin signaling and lipid transport-related genes was decreased in Cd-treated adult female offspring livers. Meanwhile, AHR, a transcription factor that combines with phospholipids to promote insulin resistance, was increased in Cd-treated adult female offspring livers. In addition, the escalation of the afore-mentioned lipid metabolites in the liver occurred as early as fetal stages in the female pups following paternal Cd exposure, suggesting the potential for these lipid species to be selected as early markers of disease for metabolic derailment later in life. Altogether, paternal Cd exposure causes offspring glucose metabolism disorder and phospholipids accumulation in a sex-dependent manner. This study provides a theoretical framework for future understanding of paternal-originated metabolic diseases.

RESUMO

Introduction: Compared to other-race peers, Black women are disproportionately impacted by human papillomavirus [HPV] infection, related health outcomes, and cervical cancer mortality as a result of suboptimal HPV vaccine uptake during adolescence. Few studies in the United States have examined psychosocial determinants of HPV vaccine acceptability and hesitancy among Black parents. The current study integrated the health belief model and the theory of planned behavior to evaluate the extent to which psychosocial factors are associated with pediatric HPV vaccination intentions among this population. Methods: Black mothers (N = 402; age range = 25 to 69 years, M = 37.45, SD = 7.88) of daughters ages 9 to 15 years completed an online survey assessing HPV infection and vaccine beliefs and attitudes across four domains: Mother's HPV Perceptions, Mother's Vaccine Attitudes, Cues to Action, and Perceived Barriers to HPV Vaccination. Participants indicated their willingness to vaccinate their daughter on a 5-level ordinal scale ("I will definitely not have my daughter get the vaccine" to "I will definitely have my daughter get the vaccine") which was dichotomously recoded for binomial logistic regressions. Results: Half of the sample (48%) intended to vaccinate their daughter. Number of daughters, mother's HPV vaccine status, perceived HPV vaccine benefits, HPV vaccine safety concerns, pediatric HPV vaccine peer norms, and doctor recommendations emerged as independent factors of Black mothers' intentions to vaccinate their daughters against HPV when controlling for all other factors. Discussion: In addition to medical training to increase doctor recommendation of the HPV vaccine for Black girls, population-tailored public health messaging aimed at promoting HPV vaccine acceptance among Black mothers is urgently needed. This messaging should engage community support and emphasize the benefits of vaccination for adolescent Black girls while also addressing parental concerns regarding the safety of pediatric HPV vaccination.
