Multilevel drivers of human immunodeficiency virus/acquired immune deficiency syndrome among black Philadelphians: Exploration using community ethnography and geographic information systems

Background: Unequal human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) distribution is influenced by certain social and structural contexts that facilitate HIV transmission and concentrate HIV in disease epicenters. Thus, one of the first steps in designing effective community-level HIV/AIDS initiatives is to disentangle the influence of individual, social, and structural factors on HIV risk. Combining ethnographic methodology with geographic information systems mapping can allow for a complex exploration of multilevel factors within communities that facilitate HIV transmission in highly affected areas. Objectives: We present the formative comparative community-based case study findings of an investigation of individual-, social-, and structural-level factors that contribute to the HIV/AIDS epidemic among Black Philadelphians. Methods: Communities were defined using census tracts. The methodology included ethnographic and geographic information systems mapping, observation, informal conversations with residents and business owners, and secondary analyses of census tract-level data in four Philadelphia neighborhoods. Results: Factors such as overcrowding, disadvantage, permeability in community boundaries, and availability and accessibility of health-related resources varied significantly. Furthermore, HIV/AIDS trended with social and structural inequities above and beyond the community's racial composition. Discussion: This study was a first step to disentangle relationships between community-level factors and potential risk for HIV in an HIV epicenter. The findings also highlight stark sociodemographic differences within and across racial groups and further substantiate the need for comprehensive, community-level HIV prevention interventions. These findings from targeted U.S. urban communities have potential applicability for examining the distribution of HIV/AIDS in broader national and international geosocial contexts

Exploring Genitoanal Injury and HIV Risk Among Women: Menstrual Phase, Hormonal Birth Control, and Injury Frequency and Prevalence

Background: Genital, anal, and oral injuries sustained from sexual intercourse may explain HIV transmission among women. We determined the variability in genitoanal injury frequency andprevalence in women after consensual sexual intercourse, exploring the role of menstrual phase and hormonal birth control. Methods: We used a longitudinal observational design with a convenience sample of 393 women aged 21 years and older. Participants had a baseline interview with gynecological examination, followed by consensual sexual intercourse with a male partner and a second gynecological examination. We analyzed injury prevalence with logistic regression and injury frequency with negative binomial regression among women who were (1) menstrual, not using hormonal birth control, (2) menstrual, using hormonal birth control, or (3) menopausal. We also compared injury among menstrual women in the follicular, ovulatory, and luteal phases. Findings: Women using hormonal birth control had 38% more external genitalia injuries [adjusted rate ratio (ARR) = 1.38, P = 0.030] and more than twice the anal injuries (ARR = 2.67, P = 0.005) as the nonhormonal birth control menstruating group. Menopausal women had more than 3 times the anal injuries (ARR = 3.36, P = 0.020) than those in the nonhormonal menstrual group. Amongmenstrual women, those in the follicular phase had a greater prevalence and frequency of external genitalia injuries than those in other phases. Interpretation: Increased rates of postcoitalgenitoanal injuries are noted among women using hormonal birth control and/or in the follicular phase of menstruation. Biological factors that influence women\u27s risk for HIV warrant further investigation

Exploring substance use tweets of youth in the United States: mixed methods study.

BACKGROUND: Substance use by youth remains a significant public health concern. Social media provides the opportunity to discuss and display substance use-related beliefs and behaviors, suggesting that the act of posting drug-related content, or viewing posted content, may influence substance use in youth. This aligns with empirically supported theories, which posit that behavior is influenced by perceptions of normative behavior. Nevertheless, few studies have explored the content of posts by youth related to substance use. OBJECTIVE: This study aimed to identify the beliefs and behaviors of youth related to substance use by characterizing the content of youths' drug-related tweets. Using a sequential explanatory mixed methods approach, we sampled drug-relevant tweets and qualitatively examined their content. METHODS: We used natural language processing to determine the frequency of drug-related words in public tweets (from 2011 to 2015) among youth Twitter users geolocated to Pennsylvania. We limited our sample by age (13-24 years), yielding approximately 23 million tweets from 20,112 users. We developed a list of drug-related keywords and phrases and selected a random sample of tweets with the most commonly used keywords to identify themes (n=249). RESULTS: We identified two broad classes of emergent themes: functional themes and relational themes. Functional themes included posts that explicated a function of drugs in one's life, with subthemes indicative of pride, longing, coping, and reminiscing as they relate to drug use and effects. Relational themes emphasized a relational nature of substance use, capturing substance use as a part of social relationships, with subthemes indicative of drug-related identity and companionship. We also identified topical areas in tweets related to drug use, including reference to polysubstance use, pop culture, and antidrug content. Across the tweets, the themes of pride (63/249, 25.3%) and longing (39/249, 15.7%) were the most popular. Most tweets that expressed pride (46/63, 73%) were explicitly related to marijuana. Nearly half of the tweets on coping (17/36, 47%) were related to prescription drugs. Very few of the tweets contained antidrug content (9/249, 3.6%). CONCLUSIONS: Data integration indicates that drugs are typically discussed in a positive manner, with content largely reflective of functional and relational patterns of use. The dissemination of this information, coupled with the relative absence of antidrug content, may influence youth such that they perceive drug use as normative and justified. Strategies to address the underlying causes of drug use (eg, coping with stressors) and engage antidrug messaging on social media may reduce normative perceptions and associated behaviors among youth. The findings of this study warrant research to further examine the effects of this content on beliefs and behaviors and to identify ways to leverage social media to decrease substance use in this population

A convergent mixed methods study of cardiovascular disease risk factors among young black men in the United States

Background: An understanding of the fac­tors that influence cardiovascular (CVD) risk among young Black men is critically needed to promote cardiovascular health earlier in the life course and prevent poor outcomes later in life. Purpose: To explore how individual (eg, de­pression, racial discrimination) and environ­mental factors (eg, neighborhood resources) are associated with CVD risk factors among young Black men. Methods: We conducted a convergent mixed methods study (qualitative/quantita­tive, QUAL+quant) with Black men aged 18 to 30 years (N = 21; 3 focus groups). Participants completed a self-administered electronic survey immediately prior to the focus groups. Results: Participants (Mage = 23) reported: two or more CVD risk factors (75%; eg, high blood pressure); racial discrimination (32%); and depressive symptoms in the past 2 weeks (50%). Five themes emerged: 1) emergence and navigation of Black manhood stressors; 2) high expectations despite limited available resources; 3) heart disease socialization: explicit and vicarious experiences; 4) managing health care needs against fear, avoidance and toughing it out; and 5) camaraderie and social support can motivate or deter. The integrated qualita­tive and quantitative analyses highlight race, gender, and class intersectionality factors that are relevant to what it means to be young, Black, male and of lower socioeco­nomic status in the United States. Conclusion: Our findings help to identify modifiable, culturally specific and contextu­ally relevant factors that relate to CVD risk factors among young Black men. Such work is crucial to inform interventions, primary prevention efforts, policies, and social-struc­tural changes to thwart the development of CVD and advanced disease stages

Vital Voices: HIV Prevention and Care Interventions Developed for Disproportionately Affected Communities by Historically Underrepresented, Early-Career Scientists.

HIV prevention interventions which support engagement in care and increased awareness of biomedical options, including pre-exposure prophylaxis (PrEP), are highly desired for disproportionately affected Black/African American, Hispanic/Latinx and gay, bisexual, and other men who have sex with men (GBMSM) populations in the United States (US). However, in almost 40 years of HIV research, few interventions have been developed directly by and for these priority populations in domestic counties most at risk. We submit that interventions developed by early-career scientists who identify with and work directly with affected subgroups, and which include social and structural determinants of health, are vital as culturally tailored HIV prevention and care tools. We reviewed and summarized interventions developed from 2007 to 2020 by historically underrepresented early-career HIV prevention scientists in a federally funded research mentoring program. We mapped these interventions to determine which were in jurisdictions deemed as high priority (based on HIV burden) by national prevention strategies. We summarized 11 HIV interventions; 10 (91%) of the 11 interventions are in geographic areas where HIV disparities are most concentrated and where new HIV prevention and care activities are focused. Each intervention addresses critical social and structural determinants of health disparities, and successfully reaches priority populations. Focused funding that supports historically underrepresented scientists and their HIV prevention and care intervention research can help facilitate reaching national goals to reduce HIV-related disparities and end the HIV epidemic. Maintaining these funding streams should remain a priority as one of the tools for national HIV prevention
