ABSTRACT
BACKGROUND: Public response to the COVID-19 pandemic has underscored the importance of trust, particularly among minority populations. Several factors might affect vaccine safety trust, including source trustworthiness. Using data from the Puerto Rico Community Engagement Alliance, we assessed the association between trust in information sources and the COVID-19 vaccine in a sample of Hispanic adults. METHODS: A cross-sectional survey-based study was conducted from November 2021 to March 2022. Participants were telephone-interviewed to assess sociodemographic, clinical, and COVID-19-related variables. Vaccine trust was assessed by how confident respondents were regarding COVID-19 vaccine safety. Trust in COVID-19 information sources was assessed by asking respondents how much they trusted selected sources of information to provide accurate information about COVID-19, including the US and Puerto Rico governments, Centers for Disease Control and Prevention (CDC), health care professionals, and traditional media (television/radio/newspaper/internet). Logistic regression models estimated the odds ratio (OR, 95% CI) of COVID-19 vaccine trust based on trust in information sources. RESULTS: A total of 200 adults aged ≥21 years completed the telephone interview. While most of the study sample (97.5%) had been inoculated with at least one dose of the COVID-19 vaccine, 86% trusted in the COVID-19 vaccine's safety. After adjusting for age and sex, participants who attested greater trust in their healthcare professionals (OR=1.99, 95% CI=0.71, 5.62), the US government (OR=2.44, 95% CI=0.69, 8.68), and the CDC (OR=8.18, 95% CI=2.97, 22.57) reported increased vaccine trust as compared to those not having great confidence in these entities. CONCLUSION: These findings support that trust in information provided by the CDC is positively associated with COVID-19 vaccine trust. Acknowledging predictors of trust regarding COVID-19 vaccination could help address factors that affect vaccine confidence. In turn, it strengthens COVID-19 prevention efforts, benefiting common welfare, reducing health disparities, and aiding underserved populations.
ABSTRACT
Background: Persons living with HIV (PLWH) have a higher risk of persistent infection with human papillomavirus (HPV) and anal cancer. We evaluated knowledge and awareness of HPV infection and risk factors for anal cancer among PLWH in Puerto Rico (PR). Methods: Data from a cross-sectional study (2020-2021) were analyzed (n=212). Inclusion criteria included PLWH, aged ≥ 26 years, and living in PR. Telephone interviews collected information on sociodemographic, lifestyle and clinical characteristics. Two 13-item scales were used to assess knowledge of HPV and anal cancer risk factors; adequate knowledge for both scales were defined as scoring >70%. Logistic regression models using generalized linear models were used to determine the association between 1) HPV infection awareness, 2) HPV infection knowledge, and 3) Anal cancer risk factors knowledge. Results: The median age was 54 years (IQR: 46,58), 67.5% were male, 71.7% reported having an income <$20,000, and 54.3% had an education level of more than high school. HPV awareness was high (82.1%), but only 40.2% and 3.8% had adequate knowledge of HPV and anal cancer risk factors, respectively. In adjusted logistic regression models, men who have sex with men (OR: 1.26, 95%CI: 1.07-1.47) and women (OR: 1.35, 95%CI: 1.15-1.59) aged ≥50 years had higher odds of HPV awareness than heterosexual men in that age group. Moreover, those with history of anal Pap test aged <50 years had more HPV awareness (OR 1.34, 95%CI: 1.08-1.66) than their counterparts. Adequate HPV knowledge was higher among participants with an education level of more than high-school (OR:1.28, 95%CI: 1.10-1.50) and with a history of HPV diagnosis (OR:1.33, 95%CI: 1.08-1.65) than their counterparts. In addition, people with good/very good/excellent health perception had higher odds of HPV knowledge (OR:1.23, 95%CI: 1.03-1.47) than those who reported poor/regular health perception. For anal cancer risk factors, PLWH for ≥15 years had increased odds of having adequate knowledge (OR:1.07, 95%CI: 1.02-1.14) than their counterparts. Conclusions: Despite high awareness of HPV, limited knowledge about HPV and anal cancer risk factors was observed among PLWH. Results from our study highlight the need for educational efforts within this population as an anal cancer prevention strategy.
ABSTRACT
Background: Limited research exists regarding the association between smoking and anal warts. In this study, we evaluated this association among a clinic-based Hispanic population in Puerto Rico. Methods: Cross-sectional study among eligible patients seen at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center (2016-2023) (n = 920). Sociodemographic and clinical variables were collected from medical records. Patients underwent a high-resolution anoscopy (HRA) during the clinical visit; physicians assessed anal condylomas on HRA. Poisson regression models with robust standard errors were used to evaluate the association between smoking and anal warts. Demographic and clinical factors were also assessed. Results: The mean age of participants was 45.8 ± 13.1 years, 66.4 % were men, and 21.6 % were current smokers. While 10.8 % self-reported a history of anogenital condylomas, 18.9 % had anal condylomas on clinical evaluation. A higher prevalence of anal condylomas was observed among current smokers (PR = 1.28, 95 % CI: 0.94-1.75) in comparison to non-smokers in adjusted analysis, but this was not statistically significant. However, a higher prevalence of anal condylomas was observed among younger individuals (PR = 0.96, 95 % CI: 0.96-0.98) and individuals with anal high-grade squamous intraepithelial lesions (HSIL) as compared to those with benign histology (PR = 1.74. 95 % CI: 1.09-2.77). Conclusions: Although current smoking seemed to be positively associated with anal condylomas in this high-risk Hispanic population, this finding was not statistically significant as the power to detect an association was limited. However, younger age and HSIL diagnosis were associated with a higher prevalence of anal condylomas.
