The Effect of Stigma and Social Networks on Role Expectations among African Immigrants Living with HIV
This paper examines how African immigrants living with HIV negotiate and reconstruct their productive (i.e., educational and career opportunities), sexual, and reproductive identities. We used data from a mixed-methods study to explore how stigma and social networks in which participants were embedded shaped how they understood and negotiated their role expectations and responsibilities. Participants revealed how HIV not only changed their identities and limited their sex life, partner choices, and fundamental decisions about fertility and reproduction, but also presented them with the opportunity to reinvent/reshape their lives. Our analysis revealed that the cultural discourses about illness and HIV in participant’s countries of origin, the acculturative and migratory stressors, and the competing influences and expectations from family and friends in their home and host countries shape their illness experience, and how they adjust to life with HIV. This paper builds on sociological understanding of illness experience as a social construct that shapes the ill person’s identity, role, and function in society. Specifically, the paper contributes to discourses on how (i) participants’ social location and identity (as transnational migrants adjusting to acculturative stressors associated with resettlement into a new country), (ii) cultural discourses about illness and HIV in their countries of origin, and (iii) embeddedness in transnational social networks influence health outcomes, including lived experiences with chronic illnesses and stigmatized conditions such as HIV.
Dimensions of Misinformation About the HPV Vaccine on Instagram: Content and Network Analysis of Social Media Characteristics
The human papillomavirus (HPV) vaccine is a major advancement in cancer prevention and this primary prevention tool has the potential to reduce and eliminate HPV-associated cancers; however, the safety and efficacy of vaccines in general and the HPV vaccine specifically have come under attack, particularly through the spread of misinformation on social media. The popular social media platform Instagram represents a significant source of exposure to health (mis)information; 1 in 3 US adults use Instagram. The objective of this analysis was to characterize pro- and anti-HPV vaccine networks on Instagram, and to describe misinformation within the anti-HPV vaccine network. From April 2018 to December 2018, we collected publicly available English-language Instagram posts containing hashtags #HPV, #HPVVaccine, or #Gardasil using Netlytic software (n=16,607). We randomly selected 10% of the sample and content analyzed relevant posts (n=580) for text, image, and social media features as well as holistic attributes (eg, sentiments, personal stories). Among antivaccine posts, we organized elements of misinformation within four broad dimensions: 1) misinformation theoretical domains, 2) vaccine debate topics, 3) evidence base, and 4) health beliefs. We conducted univariate, bivariate, and network analyses on the subsample of posts to quantify the role and position of individual posts in the network. Compared to provaccine posts (324/580, 55.9%), antivaccine posts (256/580, 44.1%) were more likely to originate from individuals (64.1% antivaccine vs 25.0% provaccine; P<.001) and include personal narratives (37.1% vs 25.6%; P=.003). In the antivaccine network, core misinformation characteristics included mentioning #Gardasil, purporting to reveal a lie (ie, concealment), conspiracy theories, unsubstantiated claims, and risk of vaccine injury. Information/resource posts clustered around misinformation domains including falsification, nanopublications, and vaccine-preventable disease, whereas personal narrative posts clustered around different domains of misinformation, including concealment, injury, and conspiracy theories. The most liked post (6634 likes) in our full subsample was a positive personal narrative post, created by a non-health individual; the most liked post (5604 likes) in our antivaccine subsample was an informational post created by a health individual. Identifying characteristics of misinformation related to HPV vaccine on social media will inform targeted interventions (eg, network opinion leaders) and help sow corrective information and stories tailored to different falsehoods.
The Effect of Social Networks and Social Constructions on HIV Risk Perceptions
Roughly 1 in 7 people living with HIV in the United States is unaware of their sero-status, signaling that individuals may be underestimating their risk for HIV. Few studies have examined the effect of socio-structural and socio-cognitive factors on HIV risk perceptions. This analysis identifies individual, interpersonal and network influences on HIV risk perceptions among high-risk heterosexuals. Data come from the Colorado Springs study, a CDC-funded project focused on HIV transmission among high-risk heterosexuals. Using social network data, analyses were first conducted at the individual-level using a partial proportional odds regression to identify predictors of self-perceived HIV risk. Next, multivariate binary logistic regression using GEE was used to examine predictors of perceptions of network member's HIV risk. Interpersonal characteristics such as perceptions of network member's HIV risk, racial homophily, and engagement in multiplexity (co-occurrence of drug-use, needle sharing and sex within relationships) were significantly associated with respondents’ self-perceived HIV risk. Factors associated with perceptions of network member's HIV risk include self-perceived HIV risk, emotional closeness within relationships, and density of drug ties. Analyses found HIV risk perception is the product of not only individual-level factors, but also interpersonal and social network processes. We also found a reciprocal relationship between individuals’ perceptions of their own risk and the risk of their associates/network members. Findings highlight the need for understanding risk perception as a function of interpersonal relationships, social constructions, including socio-cognitive processes.
Addressing COVID-19 Vaccine Hesitancy and Uptake Among African Immigrants: Lessons from a Community-Based Outreach Program
In 2021, the African Cultural Alliance of North America (ACANA) implemented a community-based vaccine education and outreach program to decrease hesitancy and increase COVID-19 vaccine uptake among African immigrants in Philadelphia. The program had three components: (1) tailored messaging on the benefits of vaccines by trusted community health navigators in familiar languages/dialects, (2) use of educational/tabling events, and (3) establishment of a vaccine clinic in community settings. Using secondary data analysis, in-depth interviews, focus group discussions and a self-administered survey, we explored (i) the impact and effectiveness of the outreach program and extent of vaccine uptake, (ii) African immigrants’ beliefs about the COVID-19 pandemic and the vaccine, and (iii) barriers and facilitators of vaccine knowledge, uptake, and hesitancy. Our analysis showed that ACANA’s outreach program was effective in addressing several cultural, logistic, and systematic barriers to vaccine uptake. The program distributed 2000 educational/informational flyers, reached 3000 community members via social media campaigns, and an additional 2320 through other person-to-person outreach events. The program was effective and resulted in the vaccination of 1265 community members over the course of the outreach. The impact of this outreach underscores the critical role of community-based organizations in addressing COVID-19 vaccine hesitancy and increasing vaccine uptake in underserved and minority communities. The paper concludes with suggestions and recommendations for using community-based outreach programs to increase COVID-19 vaccine uptake and decrease hesitancy.
Predictors of Willingness to Diffuse PrEP Information within Ego-Centric Networks of Women Who Inject Drugs
Little is known about how social networks among women who inject drugs (WWID) can be leveraged to increase awareness about pre-exposure prophylaxis (PrEP). We tested the hypothesis that interpersonal characteristics influence willingness of WWID to communicate PrEP information with peers. Forty WWID ≥ 18 years completed social network surveys. Participants named on average 9.3 (SD = 3.3) network members, resulting in 375 unique relationships. WWID were willing to share PrEP information with 83% of network members. Participants had higher odds of willingness to share information within relationships when the network member was female, homeless and perceived to be at risk for HIV. Among relationships with family members and transactional sex clients, stronger emotional closeness was associated with higher odds of willingness to share information. Peer interventions where WWID share PrEP information with peers may be an efficient approach to increase PrEP awareness among this vulnerable population.
Navigating the Challenges: A Commentary on Barriers to Autism Screening in Childcare Centers
Although the American Academy of Pediatrics has long recommended universal autism-specific screening at well-child pediatric visits, implementation challenges in primary care settings interfere with high-fidelity universal autism screening. These challenges delay autism identification for some children, leading to delays in needed services and supports. Prior findings indicate that new solutions must be developed to bridge the gap in access to autism screening for families, particularly among those who are under-resourced. One approach is expanding screening to other community settings, such as childcare centers, but there are barriers to this approach, which this commentary aims to address. We discuss challenges and barriers in childcare screening identified through our recently completed pilot study screening for autism in childcare centers, with suggested strategies to address them. These challenges include hesitation among childcare staff to guide conversations or concerns about autism, and stigma around autism diagnosis and presentation. Other challenges relate to emerging concerns regarding legal, ethical, and professional roles and responsibilities surrounding informed consent and data privacy, as well as the identification of children without timely follow-up evaluation and services. There is a need for increasing public awareness as an essential component of autism screening across settings. Our commentary discusses different considerations and practice strategies to meet these needs.
Desire for, and Uptake of HIV Tests by Ghanaian Women: The Relevance of Community Level Stigma
Voluntary counseling and testing (VCT) has been recognized as the crux of HIV surveillance, prevention and treatment programs. Since 2000, Ghana government has launched a number of HIV prevention and treatment programs intended to increase VCT services. Despite these efforts, uptake of testing is still low, though many women reported interest in getting tested. The disconnect between intention and action is attributable to several factors, including HIV-related stigma. The study used data from the 2003 Ghana Demographic and Health Survey and fitted complementary log-log models to regress women's desire for and uptake of an HIV test on levels of personal and community stigma. Consistent with findings from previous research, the study revealed significant associations between a number of socio-demographic and socio-cognitive variables and the desire for and uptake of an HIV test by Ghanaian women. Most significantly, the study showed that widespread stigma in the community exert greater negative effects on individuals who endorse stigmatizing beliefs and predispositions, compared to their peers with more favorable attitudes. Since community level educational and risk reduction programs have demonstrable influences on reducing HIV stigma, it is imperative that the Ghana government's ongoing anti-stigma campaigns and other HIV prevention programs take cognizance of the role of community stigma in influencing HIV testing.
HIV/AIDS among African Immigrants in the U.S.: The Need for Disaggregating HIV Surveillance Data by Country of Birth
The goals of the United States' National HIV/AIDS Strategy are reducing HIV infections, increasing linkage to care, and reducing health disparities. To accomplish these, it is imperative to have accurate data about HIV prevalence, especially in high-burden populations, including immigrants, ethnic/racial minorities and other minority populations. However, recent increases in HIV prevalence among Black migrants from sub-Saharan Africa has drawn attention to the need to examine the epidemiological diversity of the Black population, and accurately account for HIV prevalence within it. In most HIV surveillance data, a single category, Black/African American, is used to combine data for U.S.-born and foreign-born Blacks, including migrants from sub-Saharan Africa. Such categorizations result in under-estimation of HIV prevalence in the African immigrant population, making it difficult to allocate resources appropriately for HIV prevention and treatment. This paper highlights and provides recommendations regarding the importance of disaggregating HIV surveillance data on Blacks by country of birth.
African Immigrants and the End of the HIV Epidemic in the United States: Actionable Recommendations to Enhance Equity
African immigrants in the United States are disproportionately affected by HIV yet remain overlooked in public health strategies such as the Ending the HIV Epidemic (EHE) initiative. Many reside in EHE-prioritized counties, but their categorization under the broad “Black/African American” label obscures their distinct pathways to HIV acquisition and barriers to care. We explore how African immigrants can be more effectively prioritized in the EHE framework. We examine key challenges, including stigma, cultural and linguistic barriers, and structural inequities, that limit access to prevention and treatment services. Additionally, sociocultural factors, such as traditional health beliefs and immigration-related stressors, exacerbate these barriers. We propose actionable strategies to address these gaps, including disaggregated data collection, culturally tailored interventions, and partnerships with African immigrant communities. By aligning EHE efforts with the unique needs of this population, public health strategies can better address disparities and advance equity in the fight to end the HIV epidemic.

Explaining HIV Risk Multiplexity: A Social Network Analysis
Risk multiplexity (i.e., overlap in drug-use, needle exchange and sexual relations) is a known risk factor for HIV. However, little is known about predictors of multiplexity. This study uses egocentric data from the Colorado Springs study to examine how individual, behavioral and social network factors influence engagement in multiplex risk behavior. Analyses revealed that compared to Whites, Hispanics were significantly more likely to engage in risk multiplexity and Blacks less so. Respondents who were similar to each other (e.g., in terms of race) had significantly higher odds of being in risk multiplex relationships, and respondents’ risk perceptions and network size were significantly associated with engaging in multiplex risk behaviors. Findings from interaction analysis showed the effect of knowing someone with HIV on the odds of multiplexity depends partly on whether respondents’ know their HIV status. Findings suggest that demographics, HIV behaviors and network factors impact engagement in multiplex risk behaviors, highlighting the need for multi-level interventions aimed at reducing HIV risk behavior.
