Assessing the Impact of a PrEP Aware Week Campaign on PrEP Prescription Fills in NYS

A Scoping Review of Health Equity Interventions in Governmental Public Health

CONTEXT

Despite major efforts in research, practice, and policy, racial and ethnic disparities in health and health care persist in the United States. Interventions in collaboration with governmental public health may provide ways to address these persistent racial and ethnic health and health care disparities and improve health outcomes.

OBJECTIVE

To conduct a comprehensive review of health equity interventions performed in collaboration with public health agencies.

DESIGN

This scoping review includes intervention studies from Ovid MEDLINE, PsycINFO, and Academic Search Premier, published between 2017 and 2023. The search strategy used terminology focused on 4 concepts: race/ethnicity, equity, health departments, and epidemiologic studies.

ELIGIBILITY CRITERIA

The following inclusion criteria were determined a priori: (1) intervention tailored to reduce racial/ethnic health disparities, (2) public health department involvement, (3) health outcome measures, (4) use of epidemiologic study methods, (5) written in English, (6) implemented in the United States, (7) original data (not a commentary), and (8) published between January 2017 and January 2023.

MAIN OUTCOME MEASURES

This review focused primarily on 4 dimensions of racial health equity interventions including intervention components, intervention settings, intervention delivery agents, and intervention outcomes.

RESULTS

This review indicated that health equity interventions involving public health agencies focused on the following categories: (1) access to care, (2) health behavior, (3) infectious disease testing, (4) preventing transmission, and (5) cancer screening. Critical strategies included in interventions for reaching racial/ethnic minoritized people included using community settings, mobile clinics, social media/social networks, phone-based interventions, community-based workers, health education, active public health department involvement, and structural/policy change.

CONCLUSIONS

This scoping review aims to provide an evidence map to inform public health agencies, researchers, and funding agencies on gaps in knowledge and priority areas for future research and to identify existing health equity interventions that could be considered for implementation by public health leaders.

Individual and Health System Factors for Uptake of Pre-exposure Prophylaxis Among Young Black and Latino Gay Men

BACKGROUND

Young Black and Latino men who have sex with men (YBLMSM) have the highest rates of new HIV infections in the USA and use PrEP at lower rates than White MSM.

OBJECTIVE

To explore YBLMSM's perspectives and experiences of PrEP use to identify factors enabling or impeding uptake.

DESIGN

Qualitative study using semi-structured interviews conducted between August 2015 and April 2016.

PARTICIPANTS

Black and Latino MSM, 18-20 years of age, who live, socialize, or work in the Bronx, and were fluent in English or Spanish.

APPROACH

We used a thematic analysis to identify themes related to not taking PrEP and PrEP uptake.

KEY RESULTS

Half the participants (n = 9) were currently using PrEP, a majority had Medicaid (n = 13), all reported having a PCP, all identified English as their primary language (n = 15), and all identified as gay. Salient themes included concerns over-side effects, stigma related to HIV and sexuality, mistrust of medical providers, provider's refusal to prescribe PrEP, and insurance and cost.

CONCLUSIONS

Modifiable barriers for PrEP uptake and persistence were reported by most participants, with an emphasis on PrEP misinformation and the pervasiveness of intersectional stigma, providers' low awareness, and hesitant attitudes towards PrEP and barriers created by insurance companies. Supportive infrastructures for PrEP providers and patients are needed.

A Model of Social Media Effects in Public Health Communication Campaigns: Systematic Review

BACKGROUND

Social media platforms are frequently used in health communication campaigns. Common understandings of campaign effects posit a sequential and linear series of steps from exposure to behavior change, commonly known as the hierarchy of effects model (HOE). These concepts need to be reevaluated in the age of social media, which are interactional and communal.

OBJECTIVE

This review aims to update the traditional HOE for health communication campaigns in the context of social media, including identifying indicators of effectiveness and how these are conceptualized to lead to health-related outcomes.

METHODS

We conducted a systematic review of studies following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines reporting on the use of social media as part of health communication campaigns, extracting campaign information such as objectives, platforms used, and measures of campaign performance. We used these data, combined with our understanding of the HOE, to develop an updated conceptual model of social media campaign effects.

RESULTS

We identified 99 eligible studies reporting on 93 campaigns, published between 2012 and 2022. The campaigns were conducted in over 20 countries, but nearly half (n=42) were conducted in the United States. Campaigns targeted a variety of health issues and predominantly used Facebook, Twitter, Instagram, and YouTube. Most campaigns (n=81) set objectives targeting awareness or individual behavior change. Process measures (n=68; eg, reach and impressions) and engagement measures (n=73; eg, likes and retweets) were reported most frequently, while two-fifths (n=42) did not report any outcomes beyond engagement, such as changes in knowledge, behavior, or social norms. Most campaigns (n=55) collected measures that did not allow them to determine if the campaign objective had been met; that is, they were process evaluations only. Based on our review, our updated model suggests that campaign exposure can lead to individual behavior change and improved health outcomes, either through a direct or indirect pathway. Indirect pathways include exposure through social and policy changes. "Engagement" is positioned as critical to success, replacing awareness in the traditional HOE, and all types of engagement are treated as equal and good. No consideration is being given to potential negative engagement, such as the distribution of misinformation. Additionally, the process is no longer linear and sequential, with circular pathways evident, such as engagement not only influencing behavior change but also generating additional exposure to campaign messages.

CONCLUSIONS

Our review has highlighted a change in conventional understandings of how campaigns can influence health outcomes in the age of social media. The updated model we propose provides social media campaigners with a starting point to develop and tailor campaign messages and allows evaluators to identify critical assumptions to test, including the role and value of "engagement."

COVID-19 Messaging on Social Media for American Indian and Alaska Native Communities: Thematic Analysis of Audience Reach and Web Behavior

BACKGROUND

During the COVID-19 pandemic, tribal and health organizations used social media to rapidly disseminate public health guidance highlighting protective behaviors such as masking and vaccination to mitigate the pandemic's disproportionate burden on American Indian and Alaska Native (AI/AN) communities.

OBJECTIVE

Seeking to provide guidance for future communication campaigns prioritizing AI/AN audiences, this study aimed to identify Twitter post characteristics associated with higher performance, measured by audience reach (impressions) and web behavior (engagement rate).

METHODS

We analyzed Twitter posts published by a campaign by the Johns Hopkins Center for Indigenous Health from July 2020 to June 2021. Qualitative analysis was informed by in-depth interviews with members of a Tribal Advisory Board and thematically organized according to the Health Belief Model. A general linearized model was used to analyze associations between Twitter post themes, impressions, and engagement rates.

RESULTS

The campaign published 162 Twitter messages, which organically generated 425,834 impressions and 6016 engagements. Iterative analysis of these Twitter posts identified 10 unique themes under theory- and culture-related categories of framing knowledge, cultural messaging, normalizing mitigation strategies, and interactive opportunities, which were corroborated by interviews with Tribal Advisory Board members. Statistical analysis of Twitter impressions and engagement rate by theme demonstrated that posts featuring culturally resonant community role models (P=.02), promoting web-based events (P=.002), and with messaging as part of Twitter Chats (P<.001) were likely to generate higher impressions. In the adjusted analysis controlling for the date of posting, only the promotion of web-based events (P=.003) and Twitter Chat messaging (P=.01) remained significant. Visual, explanatory posts promoting self-efficacy (P=.01; P=.01) and humorous posts (P=.02; P=.01) were the most likely to generate high-engagement rates in both the adjusted and unadjusted analysis.

CONCLUSIONS

Results from the 1-year Twitter campaign provide lessons to inform organizations designing social media messages to reach and engage AI/AN social media audiences. The use of interactive events, instructional graphics, and Indigenous humor are promising practices to engage community members, potentially opening audiences to receiving important and time-sensitive guidance.
