Disparities in Unmet Health Care Needs Among US Children During the COVID-19 Pandemic.

PURPOSE: The COVID-19 pandemic disrupted pediatric health care in the United States, and this disruption layered on existing barriers to health care. We sought to characterize disparities in unmet pediatric health care needs during this period. METHODS: We analyzed data from Wave 1 (October through November 2020) and Wave 2 (March through May 2021) of the COVID Experiences Survey, a national longitudinal survey delivered online or via telephone to parents of children aged 5 through 12 years using a probability-based sample representative of the US household population. We examined 3 indicators of unmet pediatric health care needs as outcomes: forgone care and forgone well-child visits during fall 2020 through spring 2021, and no well-child visit in the past year as of spring 2021. Multivariate models examined relationships of child-, parent-, household-, and county-level characteristics with these indicators, adjusting for child's age, sex, and race/ethnicity. RESULTS: On the basis of parent report, 16.3% of children aged 5 through 12 years had forgone care, 10.9% had forgone well-child visits, and 30.1% had no well-child visit in the past year. Adjusted analyses identified disparities in indicators of pediatric health care access by characteristics at the level of the child (eg, race/ethnicity, existing health conditions, mode of school instruction), parent (eg, childcare challenges), household (eg, income), and county (eg, urban-rural classification, availability of primary care physicians). Both child and parent experiences of racism were also associated with specific indicators of unmet health care needs. CONCLUSIONS: Our findings highlight the need for continued research examining unmet health care needs and for continued efforts to optimize the clinical experience to be culturally inclusive.

Combined Infection Control Interventions Protect Essential Food Workers from Occupational Exposures to SARS-CoV-2 in the Agricultural Environment.

Essential food workers experience elevated risks of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection due to prolonged occupational exposures in food production and processing areas, shared transportation (car or bus), and employer-provided shared housing. Our goal was to quantify the daily cumulative risk of SARS-CoV-2 infection for healthy susceptible produce workers and to evaluate the relative reduction in risk attributable to food industry interventions and vaccination. We simulated daily SARS-CoV-2 exposures of indoor and outdoor produce workers through six linked quantitative microbial risk assessment (QMRA) model scenarios. For each scenario, the infectious viral dose emitted by a symptomatic worker was calculated across aerosol, droplet, and fomite-mediated transmission pathways. Standard industry interventions (2-m physical distancing, handwashing, surface disinfection, universal masking, ventilation) were simulated to assess relative risk reductions from baseline risk (no interventions, 1-m distance). Implementation of industry interventions reduced an indoor worker's relative infection risk by 98.0% (0.020; 95% uncertainty interval [UI], 0.005 to 0.104) from baseline risk (1.00; 95% UI, 0.995 to 1.00) and an outdoor worker's relative infection risk by 94.5% (0.027; 95% UI, 0.013 to 0.055) from baseline risk (0.487; 95% UI, 0.257 to 0.825). Integrating these interventions with two-dose mRNA vaccinations (86 to 99% efficacy), representing a worker's protective immunity to infection, reduced the relative infection risk from baseline for indoor workers by 99.9% (0.001; 95% UI, 0.0002 to 0.005) and outdoor workers by 99.6% (0.002; 95% UI, 0.0003 to 0.005). Consistent implementation of combined industry interventions, paired with vaccination, effectively mitigates the elevated risks from occupationally acquired SARS-CoV-2 infection faced by produce workers. IMPORTANCE This is the first study to estimate the daily risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection across a variety of indoor and outdoor environmental settings relevant to food workers (e.g., shared transportation [car or bus], enclosed produce processing facility and accompanying breakroom, outdoor produce harvesting field, shared housing facility) through a linked quantitative microbial risk assessment framework. Our model has demonstrated that the elevated daily SARS-CoV-2 infection risk experienced by indoor and outdoor produce workers can be reduced below 1% when vaccinations (optimal vaccine efficacy, 86 to 99%) are implemented with recommended infection control strategies (e.g., handwashing, surface disinfection, universal masking, physical distancing, and increased ventilation). Our novel findings provide scenario-specific infection risk estimates that can be utilized by food industry managers to target high-risk scenarios with effective infection mitigation strategies, which was informed through more realistic and context-driven modeling estimates of the infection risk faced by essential food workers daily. Bundled interventions, particularly if they include vaccination, yield significant reductions (>99%) in daily SARS-CoV-2 infection risk for essential food workers in enclosed and open-air environments.

Effects of mode of transportation on PrEP persistence among urban men who have sex with men.

Little is known about the effect of travel-related factors, such as mode of transportation, on retention in PrEP care, or PrEP persistence. We used data from the 2020 American Men's Internet Survey and conducted multilevel logistic regression to estimate the association between mode of transportation used for healthcare access and PrEP persistence among urban gay, bisexual, and other men who have sex with men (MSM) in the U.S. MSM using public transportation were less likely to report PrEP persistence (aOR: 0.51; 95% CI: 0.28-0.95) than MSM using private transportation. There were no significant associations between PrEP persistence and using active transportation (aOR: 0.67; 95% CI: 0.35-1.29) or multimodal transportation (aOR: 0.85; 95% CI: 0.51-1.43) compared to using private transportation. Transportation-related interventions and policies are needed to address structural barriers to accessing PrEP services and to improve PrEP persistence in urban areas.

Training Young Adult Peers in a Mobile Motivational Interviewing-Based Mentoring Approach to Upstream HIV Prevention.

Mentoring relationships are characterized by a sustained, high quality, and skill-building relationship between a protégé and mentor (Handbook of Youth Mentoring, Los Angeles, SAGE, 2014). Within prevention science, youth mentoring programs emphasize creating a specific context that benefits a young person. Program-sponsored relationships between youth and adults allow for creating a mentor-mentee partnership, but do not require the establishment of a strong bond in order to deliver prevention-focused activities and experiences (Handbook of Youth Mentoring, Los Angeles, SAGE, 2014). Motivational Interviewing (MI) is a counseling style used widely to promote health behavior change and in prevention interventions. As part of an upstream approach to HIV prevention, we combined mentoring and MI by training peer mentors to use MI skills in their interactions as part of a large RCT of a mobile life skills intervention for adolescent men who have sex with men (AMSM). Our training model developed for training peer mentors in MI skills resulted in peers reaching and exceeding established MI fidelity thresholds (e.g., mean percentage of complex reflections = 80%, mean reflection to question ratio = 2.2:1). We offer reflections on lessons learned and future directions for those researchers and practitioners who may benefit from adapting this blended approach for mentoring AMSM.

Equity of PrEP uptake by race, ethnicity, sex and region in the United States in the first decade of PrEP: a population-based analysis.

Background: PrEP was approved for HIV prevention in the US in 2012; uptake has been slow. We describe relative equity with the PrEP Equity Ratio (PER), a ratio of PrEP-to-Need Ratios (PnRs). Methods: We used commercial pharmacy data to enumerate PrEP users by race and ethnicity, sex, and US Census region from 2012 to 2021. We report annual race and ethnicity-, sex-, and region-specific rates of PrEP use and PnR, a metric of PrEP equity, to assess trends. Findings: PrEP use increased for Black, Hispanic and White Americans from 2012 to 2021. By 2021, the rate of PrEP use per population was similar in Black and White populations but slightly lower among Hispanic populations. PnR increased from 2012 to 2021 for all races and ethnicities and regions; levels of PrEP use were inconsistent across regions and highly inequitable by race, ethnicity, and sex. In all regions, PnR was highest for White and lowest for Black people. Inequity in PrEP use by race and ethnicity, as measured by the PER, grew early after availability of PrEP and persisted at a level substantially below equitable PrEP use. Interpretation: From 2012 to 2021, PrEP use increased among Americans, but PrEP equity for Black and Hispanic Americans decreased. The US South lagged all regions in equitable PrEP use. Improved equity in PrEP use will be not only just, but also impactful on the US HIV epidemic; persons most at-risk of acquiring HIV should have the highest levels of access to PrEP. Prevention programs should be guided by PrEP equity, not PrEP equality. Funding: National Institutes of Health, Gilead Sciences.

Association between the geographic accessibility of PrEP and PrEP use among MSM in nonurban areas.

PURPOSE: The US HIV epidemic has become a public health issue that increasingly affects men who have sex with men (MSM), including those residing in nonurban areas. Increasing access to pre-exposure prophylaxis (PrEP) in nonurban areas will prevent HIV acquisition and could address the growing HIV epidemic. No studies have quantified the associations between PrEP access and PrEP use among nonurban MSM. METHODS: Using 2020 PrEP Locator data and American Men's Internet Survey data, we conducted multilevel log-binomial regression to examine the association between area-level geographic accessibility of PrEP-providing clinics and individual-level PrEP use among MSM residing in nonurban areas in the United States. FINDINGS: Of 4,792 PrEP-eligible nonurban MSM, 20.1% resided in a PrEP desert (defined as more than a 30-minute drive to access PrEP), and 15.2% used PrEP in the past 12 months. In adjusted models, suburban MSM residing in PrEP deserts were less likely to use PrEP in the past year (adjusted prevalence ratio [aPR] = 0.35; 95% confidence interval [CI] = 0.15, 0.80) than suburban MSM not residing in PrEP deserts, and other nonurban MSM residing in PrEP deserts were less likely to use PrEP in the past year (aPR = 0.75; 95% CI = 0.60, 0.95) than other nonurban MSM not residing in PrEP deserts. CONCLUSIONS: Structural interventions designed to decrease barriers to PrEP access that are unique to nonurban areas in the United States are needed to address the growing HIV epidemic in these communities.

Trends in the use of oral emtricitabine/tenofovir disoproxil fumarate for pre-exposure prophylaxis against HIV infection, United States, 2012-2017.

PURPOSE: Pre-exposure prophylaxis (PrEP) with oral emtricitibine/tenofovir disoproxil fumarate (TDF/FTC) reduces the risk of HIV infection by >90% when taken as prescribed. Trends in prevalence of PrEP use, which account for persons who have stopped PrEP, increased through 2016, but have not been described since. METHODS: Annual prevalence estimates of unique, TDF/FTC PrEP users (individuals with ≥1 day of a filled PrEP prescription in a given year) in the United States (US) were generated for 2012-2017 from a national prescription database. A validated algorithm was used to distinguish users of TDF/FTC for HIV or chronic Hepatitis B treatment or postexposure prophylaxis from PrEP users. We calculated annual prevalence of PrEP use overall and by age, sex, and region. We used log-transformation to calculate estimated annual percent change (EAPC) in the prevalence of PrEP use. RESULTS: Annual prevalence of PrEP use increased from 3.3/100,000 population in 2012 to 36.7 in 2017 -a 56% annual increase from 2012 to 2017 (EAPC: +56%). Annual prevalence of PrEP use increased faster among men than among women (EAPC: +68% and +5%, respectively). By age group, annual prevalence of PrEP use increased fastest among 25- to 34-year olds (EAPC: +61%) and slowest among ≥55-year olds (EAPC: +52%) and ≤24-year olds (EAPC: +51%). In 2017, PrEP use was lowest in the South (29.8/100,000) and highest in the Northeast (62.3/100,000). CONCLUSIONS: Despite overall increases in the annual number of TDF/FTC PrEP users in the US from 2012 to 2017, the growth of PrEP coverage is inconsistent across groups. Efforts to optimize PrEP access are especially needed for women and for those living in the South.
