Estimating the Period Prevalence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection During the Omicron (BA.1) Surge in New York City (NYC), 1 January to 16 March 2022.

In a population-based survey of adults in New York City, we assessed positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests (including via exclusive at-home testing) and possible cases among untested respondents. An estimated 27.4% (95% confidence interval [CI]: 22.8%-32.0%) or 1.8 million adults (95% CI: 1.6-2.1 million) had SARS-CoV-2 infection between 1 January and 16 March 2022.

The Epidemiology of Long Coronavirus Disease in US Adults.

BACKGROUND: We estimated the prevalence of long COVID and impact on daily living among a representative sample of adults in the United States. METHODS: We conducted a population-representative survey, 30 June-2 July 2022, of a random sample of 3042 US adults aged 18 years or older and weighted to the 2020 US population. Using questions developed by the UK's Office of National Statistics, we estimated the prevalence of long COVID, by sociodemographics, adjusting for gender and age. RESULTS: An estimated 7.3% (95% confidence interval: 6.1-8.5%) of all respondents reported long COVID, corresponding to approximately 18 828 696 adults. One-quarter (25.3% [18.2-32.4%]) of respondents with long COVID reported their day-to-day activities were impacted "a lot" and 28.9% had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection more than 12 months ago. The prevalence of long COVID was higher among respondents who were female (adjusted prevalence ratio [aPR]: 1.84 [1.40-2.42]), had comorbidities (aPR: 1.55 [1.19-2.00]), or were not (vs were) boosted (aPR: 1.67 [1.19-2.34]) or not vaccinated (vs boosted) (aPR: 1.41 [1.05-1.91]). CONCLUSIONS: We observed a high burden of long COVID, substantial variability in prevalence of SARS-CoV-2, and risk factors unique from SARS-CoV-2 risk, suggesting areas for future research. Population-based surveys are an important surveillance tool and supplement to ongoing efforts to monitor long COVID.

Severe Acute Respiratory Syndrome Coronavirus 2 Incidence and Risk Factors in a National, Community-Based Prospective Cohort of US Adults.

BACKGROUND: Prospective cohort studies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) incidence complement case-based surveillance and cross-sectional seroprevalence surveys. METHODS: We estimated the incidence of SARS-CoV-2 infection in a national cohort of 6738 US adults, enrolled in March-August 2020. Using Poisson models, we examined the association of social distancing and a composite epidemiologic risk score with seroconversion. The risk score was created using least absolute shrinkage selection operator (LASSO) regression to identify factors predictive of seroconversion. The selected factors were household crowding, confirmed case in household, indoor dining, gathering with groups of ≥10, and no masking in gyms or salons. RESULTS: Among 4510 individuals with ≥1 serologic test, 323 (7.3% [95% confidence interval (CI), 6.5%-8.1%]) seroconverted by January 2021. Among 3422 participants seronegative in May-September 2020 and retested from November 2020 to January 2021, 161 seroconverted over 1646 person-years of follow-up (9.8 per 100 person-years [95% CI, 8.3-11.5]). The seroincidence rate was lower among women compared with men (incidence rate ratio [IRR], 0.69 [95% CI, .50-.94]) and higher among Hispanic (2.09 [1.41-3.05]) than white non-Hispanic participants. In adjusted models, participants who reported social distancing with people they did not know (IRR for always vs never social distancing, 0.42 [95% CI, .20-1.0]) and with people they knew (IRR for always vs never, 0.64 [.39-1.06]; IRR for sometimes vs never, 0.60 [.38-.96]) had lower seroconversion risk. Seroconversion risk increased with epidemiologic risk score (IRR for medium vs low score, 1.68 [95% CI, 1.03-2.81]; IRR for high vs low score, 3.49 [2.26-5.58]). Only 29% of those who seroconverted reported isolating, and only 19% were asked about contacts. CONCLUSIONS: Modifiable risk factors and poor reach of public health strategies drove SARS-CoV-2 transmission across the United States.

Modeling angiogenesis in the human brain in a tissue-engineered post-capillary venule.

Angiogenesis plays an essential role in embryonic development, organ remodeling, wound healing, and is also associated with many human diseases. The process of angiogenesis in the brain during development is well characterized in animal models, but little is known about the process in the mature brain. Here, we use a tissue-engineered post-capillary venule (PCV) model incorporating stem cell derived induced brain microvascular endothelial-like cells (iBMECs) and pericyte-like cells (iPCs) to visualize the dynamics of angiogenesis. We compare angiogenesis under two conditions: in response to perfusion of growth factors and in the presence of an external concentration gradient. We show that both iBMECs and iPCs can serve as tip cells leading angiogenic sprouts. More importantly, the growth rate for iPC-led sprouts is about twofold higher than for iBMEC-led sprouts. Under a concentration gradient, angiogenic sprouts show a small directional bias toward the high growth factor concentration. Overall, pericytes exhibited a broad range of behavior, including maintaining quiescence, co-migrating with endothelial cells in sprouts, or leading sprout growth as tip cells.

The prevalence of SARS-CoV-2 infection and long COVID in U.S. adults during the BA.4/BA.5 surge, June-July 2022.

Due to changes in SARS-CoV-2 testing practices, passive case-based surveillance may be an increasingly unreliable indicator for monitoring the burden of SARS-CoV-2, especially during surges. We conducted a cross-sectional survey of a population-representative sample of 3042 U.S. adults between June 30 and July 2, 2022, during the Omicron BA.4/BA.5 surge. Respondents were asked about SARS-CoV-2 testing and outcomes, COVID-like symptoms, contact with cases, and experience with prolonged COVID-19 symptoms following prior infection. We estimated the weighted age and sex-standardized SARS-CoV-2 prevalence, during the 14-day period preceding the interview. We estimated age and gender adjusted prevalence ratios (aPR) for current SARS-CoV-2 infection using a log-binomial regression model. An estimated 17.3% (95% CI 14.9, 19.8) of respondents had SARS-CoV-2 infection during the two-week study period-equating to 44 million cases as compared to 1.8 million per the CDC during the same time period. SARS-CoV-2 prevalence was higher among those 18-24 years old (aPR 2.2, 95% CI 1.8, 2.7) and among non-Hispanic Black (aPR 1.7, 95% CI 1.4,2.2) and Hispanic adults (aPR 2.4, 95% CI 2.0, 2.9). SARS-CoV-2 prevalence was also higher among those with lower income (aPR 1.9, 95% CI 1.5, 2.3), lower education (aPR 3.7 95% CI 3.0,4.7), and those with comorbidities (aPR 1.6, 95% CI 1.4, 2.0). An estimated 21.5% (95% CI 18.2, 24.7) of respondents with a SARS-CoV-2 infection >4 weeks prior reported long COVID symptoms. The inequitable distribution of SARS-CoV-2 prevalence during the BA.4/BA.5 surge will likely drive inequities in the future burden of long COVID.

Psychosocial Stressors and Maternal Mental Health in the U.S. During the First Wave of the COVID-19 Pandemic: A Cross-Sectional Analysis.

OBJECTIVES: The COVID pandemic has had widespread impacts on maternal mental health. This research aims to examine the relationship between psychosocial stressors and symptoms of depression and anxiety and the extent to which emotional support or resilient coping moderates the relationship between psychosocial stressors and maternal mental health during the first wave of the COVID pandemic. METHODS: This analysis includes data collected in October and November 2020 from a geographically and sociodemographically diverse sample of 776 mothers in the U.S. with children ≤ 18 years of age. Log binomial models were used to estimate the association between moderate or severe symptoms of anxiety and depression and psychosocial stressors. RESULTS: Symptoms of moderate or severe anxiety and depression were reported by 37.5% and 37.6% of participants, respectively. Moderate (aRR 2.76 [95% CI 1.87, 4.07]) and high (aRR 4.95 [95% CI 3.40, 7.20]) levels of perceived stress were associated with greater risk of moderate or severe anxiety symptoms. Moderate and high levels of parental burnout were also associated with greater prevalence of moderate or severe anxiety symptoms in multivariable models. Results were similar when examining the relationship among stress, parental burnout, and depressive symptoms. Neither resilient coping nor social support modified the relationship between psychosocial stressors and mental health. CONCLUSIONS FOR PRACTICE: Evidence-based strategies to reduce stress and parental burnout and improve the mental health of mothers are urgently needed. Strategies focused on bolstering coping and social support may be insufficient to improve maternal mental health during acute public health emergencies.

Racial/Ethnic Disparities in Exposure, Disease Susceptibility, and Clinical Outcomes during COVID-19 Pandemic in National Cohort of Adults, United States.

We examined racial/ethnic disparities for COVID-19 seroconversion and hospitalization within a prospective cohort (n = 6,740) in the United States enrolled in March 2020 and followed-up through October 2021. Potential SARS-CoV-2 exposure, susceptibility to COVID-19 complications, and access to healthcare varied by race/ethnicity. Hispanic and Black non-Hispanic participants had more exposure risk and difficulty with healthcare access than white participants. Participants with more exposure had greater odds of seroconversion. Participants with more susceptibility and more barriers to healthcare had greater odds of hospitalization. Race/ethnicity positively modified the association between susceptibility and hospitalization. Findings might help to explain the disproportionate burden of SARS-CoV-2 infections and complications among Hispanic/Latino/a and Black non-Hispanic persons. Primary and secondary prevention efforts should address disparities in exposure, vaccination, and treatment for COVID-19.

Determinants and Trends of COVID-19 Vaccine Hesitancy and Vaccine Uptake in a National Cohort of US Adults: A Longitudinal Study.

We estimated the trends and correlates of vaccine hesitancy and its association with subsequent vaccine uptake among 5,458 adults in the United States. Participants belonged to the Communities, Households, and SARS-CoV-2 Epidemiology COVID (CHASING COVID) Cohort, a national longitudinal study. Trends and correlates of vaccine hesitancy were examined longitudinally in 8 interview rounds from October 2020 to July 2021. We also estimated the association between willingness to vaccinate and subsequent vaccine uptake through July 2021. Vaccine delay and refusal decreased from 51% and 8% in October 2020 to 8% and 6% in July 2021, respectively. Compared with non-Hispanic (NH) White participants, NH Black and Hispanic participants had higher adjusted odds ratios (aOR) for both vaccine delay (for NH Black, aOR = 2.0 (95% confidence interval (CI): 1.5, 2.7), and for Hispanic, 1.3 (95% CI: 1.0, 1.7)) and vaccine refusal (for NH Black, aOR = 2.5 (95% CI: 1.8, 3.6), and for Hispanic, 1.4 (95% CI: 1.0, 2.0)) in June 2021. COVID-19 vaccine hesitancy, compared with vaccine-willingness, was associated with lower odds of subsequent vaccine uptake (for vaccine delayers, aOR = 0.15, 95% CI: 0.13, 0.18; for vaccine refusers, aOR = 0.02; 95% CI: 0.01, 0.03 ), adjusted for sociodemographic factors and COVID-19 history. Vaccination awareness and distribution efforts should focus on vaccine delayers.

Engineering the human blood-brain barrier at the capillary scale using a double-templating technique.

In vitro blood-brain barrier (BBB) models have played an important role in studying processes such as immune cell trafficking and drug delivery, as well as contributing to the understanding of mechanisms of disease progression. Many biological and pathological processes in the cerebrovasculature occur in capillaries and hence the lack of robust hierarchical models at the capillary scale is a major roadblock in BBB research. Here we report on a double-templating technique for engineering hierarchical BBB models with physiological barrier function at the capillary scale. We first demonstrate the formation of hierarchical vascular networks using human umbilical vein endothelial cells. We then characterize barrier function in a BBB model using brain microvascular endothelial-like cells (iBMECs) differentiated from induced pluripotent stem cells (iPSCs). Finally, we characterize immune cell adhesion and transmigration in response to perfusion with the inflammatory cytokine tumor necrosis factor-alpha, and show that we can recapitulate capillary-scale effects, such as leukocyte plugging, observed in mouse models. Our double-templated hierarchical model enables the study of a wide range of biological and pathological processes related to the human BBB.

Menstrual Product Insecurity Resulting From COVID-19‒Related Income Loss, United States, 2020.

Objectives. To identify key effects of the pandemic and its economic consequences on menstrual product insecurity with implications for public health practice and policy. Methods. Study participants (n = 1496) were a subset of individuals enrolled in a national (US) prospective cohort study. Three survey waves were included (March‒October 2020). Menstrual product insecurity outcomes were explored with bivariate associations and logistic regression models to examine the associations between outcomes and income loss. Results. Income loss was associated with most aspects of menstrual product insecurity (adjusted odds ratios from 1.34 to 3.64). The odds of not being able to afford products for those who experienced income loss was 3.64 times (95% confidence interval [CI] = 2.14, 6.19) that of those who had no income loss and 3.95 times (95% CI = 1.78, 8.79) the odds for lower-income participants compared with higher-income participants. Conclusions. Pandemic-related income loss was a strong predictor of menstrual product insecurity, particularly for populations with lower income and educational attainment. Public Health Implications. Provision of free or subsidized menstrual products is needed by vulnerable populations and those most impacted by pandemic-related income loss.(Am J Public Health. 2022;112(4):675-684. (https://doi.org/10.2105/AJPH.2021.306674).

Missed routine pediatric care and vaccinations in US children during the first year of the COVID-19 pandemic.

The COVID-19 pandemic has decreased uptake of pediatric preventive care, including immunizations. We estimate the prevalence of missed pediatric routine medical visits and vaccinations over the first year of the COVID-19 pandemic. We conducted a cross-sectional online survey of 2074 US parents of children ≤12 years in March 2021 to measure the proportion of children who missed pediatric care and vaccinations over the first 12 months of the COVID-19 pandemic. Poisson regression models were fitted to estimate adjusted prevalence ratios (aPR). All analyses were weighted to represent the target population. Overall, 41.3% (95%CI 38.3-43.8) of parents reported their youngest child missed a routine medical visit due to the COVID-19 pandemic. Missed care was more common among children ≥2 years compared to <2 years (aPR 1.82; 95%CI 1.47-2.26) and Hispanics compared to non-Hispanic Whites (aPR 1.31; 95%CI 1.14-1.51). A third of parents (33.1%; 95%CI 30.7-35.5) reported their child had missed a vaccination. Compared to the 2019-20 flu season, pediatric influenza vaccination decreased in 2020-21 (51.3% vs. 62.2%; p < 0.0001). A high proportion of US children ≤12 years missed routine pediatric care during the COVID-19 pandemic. Catch-up efforts are needed to ensure continuity of preventive care for all children.

Sex in the Era of COVID-19 in a U.S. National Cohort of Cisgender Men, Transgender Women, and Transgender Men Who Have Sex with Men: April-May 2020.

Since the emergence of the COVID-19 pandemic, there has been an increasing body of research focused on the effects that measures like stay-at-home orders and social distancing are having on other aspects of health, including mental health and sexual health. Currently, there are limited extant data on the effects of the pandemic on sexual and gender minorities. Between April 15, 2020, and May 15, 2020, we invited participants in an ongoing U.S. national cohort study (Together 5000) to complete a cross-sectional online survey about the pandemic, and its effects on mental and sexual health and well-being (n = 3991). Nearly all (97.7%) were living in an area where they were told they should only leave their homes for essentials. Most (70.1%) reported reducing their number of sex partners as a result of the pandemic. Among the 789 participants prescribed HIV pre-exposure prophylaxis (PrEP), 29.9% said they stopped taking their PrEP entirely, and 14.2% started selectively skipping doses. For those who had been taking PrEP, discontinuing PrEP was associated with having no new sex partners (ß = 0.90, 95% CI 0.40-1.40). Among the 152 HIV-positive participants, 30.9% said they were unable to maintain an HIV-related medical appointment because of the pandemic and 13.8% said they had been unable to retrieve HIV medications. Additionally, 35.3% of participants were experiencing moderate to severe anxiety because of the pandemic and 36.7% reported symptoms of depression. In a multivariable logistic regression, reporting a new sex partner in the prior 30 days was significantly associated with being aged 30 or older (vs. not, AOR = 1.21), being Black (AOR = 1.79) or Latinx (AOR = 1.40, vs. white), and being unsure if they had been in close contact with someone diagnosed with COVID-19 (AOR = 1.32, vs. no contact). It was unassociated with COVID-19-induced anxiety, depression, or knowing someone hospitalized with COVID-19. The pandemic has caused disruptions in sexual behavior (partner reduction) as well as difficulties navigating PrEP and HIV care continua. Findings will guide more comprehensive public health responses to optimize HIV prevention and treatment in the era of COVID-19.

Tracing-corrected estimates of disengagement from HIV care and mortality among patients enrolling in HIV care without overt immunosuppression in Tanzania.

In the era of "test and treat", it is important to understand HIV care outcomes and their determinants in patients presenting to care with early-stage disease. We surveyed 924 adults newly enrolling in HIV care at four clinics in Tanzania before the adoption of universal treatment eligibility, and collected longitudinal clinical data. Participants who defaulted from care were tracked in the community. Cumulative incidence of disengagement from care and death was estimated using competing risk methods. By 12 months after enrollment, 18.2% of patients had disengaged from care and 6.9% had died. Factors associated with disengagement included male sex (adjusted subhazard ratio [aSHR] versus female = 1.75, 95% confidence interval [CI]: 1.06-2.89), provider-initiated HIV diagnosis (aSHR versus self-referred = 1.71, 95% CI: 1.03-2.86), ineligibility for antiretroviral treatment (ART) at enrollment (aSHR versus eligibility = 2.82, 95% CI: 1.84-4.32) and increased anticipated stigma score (aSHR = 1.04 per 5-point increase, 95% CI: 1.02-1.05). Higher life satisfaction score (aSHR = 0.97 per 5-point increase, 95% CI: 0.95-0.99) and having 1-2 close friends (aSHR versus none = 0.58, 95% CI: 0.47-0.71) were protective. The findings highlight the continued importance of social environment for HIV care outcomes and the potential of universal ART eligibility to reduce HIV care attrition.

HIV Care Coordination promotes care re-engagement and viral suppression among people who have been out of HIV medical care: an observational effectiveness study using a surveillance-based contemporaneous comparison group.

BACKGROUND: Medical care re-engagement is critical to suppressing viral load and preventing HIV transmission, morbidity and mortality, yet few rigorous intervention studies address this outcome. We assessed the effectiveness of a Ryan White Part A-funded HIV Care Coordination Program relative to 'usual care,' for short-term care re-engagement and viral suppression among people without recent HIV medical care. METHODS: The Care Coordination Program was launched in 2009 at 28 hospitals, health centers, and community-based organizations in New York City. Designed for people with HIV (PWH) experiencing or at risk for poor HIV outcomes, the Care Coordination Program provides long-term, comprehensive medical case management utilizing interdisciplinary teams, structured health education and patient navigation. The intervention was implemented as a safety-net services program, without a designated comparison group. To evaluate it retrospectively, we created an observational, matched cohort of clients and controls. Using the HIV surveillance registry, we identified individuals meeting program eligibility criteria from December 1, 2009 to March 31, 2013 and excluded those dying prior to 12 months of follow-up. We then matched clients to controls on baseline status (lacking evidence of viral suppression, consistently suppressed, inconsistently suppressed, or newly diagnosed in the past 12 months), start of follow-up and propensity score. For this analysis, we limited to those out of care at baseline (defined as having no viral load test in the 12 months pre-enrollment) and still residing within jurisdiction (defined as having a viral load or CD4 test reported to local surveillance and dated within the 12-month follow-up period). Using a GEE model with binary error distribution and logit link, we compared odds of care re-engagement (defined as having ≥ 2 laboratory events ≥ 90 days apart) and viral suppression (defined as having HIV RNA ≤ 200 copies/mL on the most recent viral load test) at 12-month follow-up. RESULTS: Among 326 individuals out of care at baseline, 87.2% of clients and 48.2% of controls achieved care re-engagement (Odds Ratio: 4.53; 95%CI 2.66, 7.71); 58.3% of clients and 49.3% of controls achieved viral suppression (Odds Ratio: 2.05; 95%CI 1.30, 3.23). CONCLUSIONS: HIV Care Coordination shows evidence of effectiveness for care and treatment re-engagement.

Gender, HIV-Related Stigma, and Health-Related Quality of Life Among Adults Enrolling in HIV Care in Tanzania.

HIV-related stigma has been associated with worse health-related quality of life (HRQoL) among people living with HIV (PLWH). Little is known about how different types of HIV-related stigma (i.e., anticipatory, internalized, or enacted HIV-related stigma) influence HRQoL and whether these relationships differ by gender. The sample included 912 PLWH aged 18 years or older enrolling in HIV care at four health facilities in Tanzania. HRQoL was assessed with the life satisfaction and overall function subscales of the HIV/AIDS-Targeted Quality of Life (HAT-QoL) instrument. Sex-stratified multivariable logistic regression modeled the association of anticipatory, internalized, and enacted HIV-related stigma on poor HRQoL. Across all participants, the mean life satisfaction score was 63.4 (IQR: 43.8, 81.3) and the mean overall function score was 72.0 (IQR: 58.3, 91.7). Mean HRQoL scores were significantly higher for women compared to men for overall function (5.1 points higher) and life satisfaction (4.3 points higher). Fourteen percent of respondents reported recent enacted HIV-related stigma and 13% reported recent medium or high levels of internalized stigma. In multivariable models, high internalized and high anticipatory stigma were significantly associated with higher odds of poor life satisfaction and poor overall function in both men and women. Psychosocial interventions to prevent or reduce the impact of internalized and anticipatory stigma may improve HRQoL among persons in HIV care. Future research should longitudinally examine mechanisms between HIV-related stigma, poor HRQoL, and HIV care outcomes.

Gender Differences and Psychosocial Factors Associated with Problem Drinking Among Adults Enrolling in HIV Care in Tanzania.

Problem drinking is commonly reported among people living with HIV (PLWH), associated with suboptimal HIV care outcomes and differs by gender. Psychosocial factors associated with problem drinking among PLWH remain poorly understood, including whether they differ by gender. This analysis examines the relationship between psychosocial factors and problem drinking separately by gender among PLWH in Tanzania. Cross-sectional data were collected from 812 men and non-pregnant women living with HIV aged 18 or older enrolling in HIV care at four health facilities in Tanzania. Problem drinking was assessed with the CAGE Questionnaire and defined as responding yes to two or more items. Sex-stratified multivariable logistic regression modeled the association of social support, HIV-related stigma, and physical or sexual violence on problem drinking, controlling for age, relationship status, employment, having been away from home for more than  one month, and timing of first HIV-positive diagnosis. Thirteen percent of the sample reported problem drinking, with problem drinking significantly more commonly reported among men than non-pregnant women (17.6% vs. 9.5%). Among men and non-pregnant women, in multivariable analyses, enacted and internalized HIV-related stigma were significantly positively associated with problem drinking. Screening and treatment of problem drinking should be integrated into HIV care. Evidence-based substance abuse interventions should be adapted to address HIV-related stigma. Future research should longitudinally investigate the interrelationships between stigma, violence, and problem drinking among PLWH.

Psychosocial Factors Associated with Food Insufficiency Among People Living with HIV/AIDS (PLWH) Initiating ART in Ethiopia.

Food insufficiency is associated with suboptimal HIV treatment outcomes. Less is known about psychosocial correlates of food insufficiency among PLWH. This sample includes 1176 adults initiating antiretroviral therapy at HIV clinics in Ethiopia. Logistic regression modeled the association of psychological distress, social support, and HIV-related stigma with food insufficiency. Among respondents, 21.4% reported frequent food insufficiency. Psychological distress [adjusted odds ratio (aOR) 2.61 (95% CI 1.79, 3.82)], low social support [aOR 2.20 (95% CI 1.57, 3.09)] and enacted stigma [aOR 1.69 (95% CI 1.26, 2.25)] were independently associated with food insufficiency. Food insufficiency interventions should address its accompanying psychosocial context.

Using Registry Data to Construct a Comparison Group for Programmatic Effectiveness Evaluation: The New York City HIV Care Coordination Program.

Many nonrandomized interventions rely upon a pre-post design to evaluate effectiveness. Such designs cannot account for events external to the intervention that may produce the outcome. We describe a method to construct a surveillance registry-based comparison group, which allows for estimating the effectiveness of the intervention while controlling for secular trends in the outcome of interest. Using data from the population-based, human immunodeficiency virus Surveillance Registry in New York City, we created a contemporaneous comparison group for persons enrolled in the New York City human immunodeficiency virus Care Coordination Program (CCP) from December 2009 to March 2013. Inclusion in the Registry-based (non-CCP) comparison group required meeting CCP eligibility criteria. To control for secular trends in the outcome, we randomly assigned persons in the non-CCP, Registry-based comparison group a pseudoenrollment date such that the distribution of pseudoenrollment dates matched the distribution of enrollment dates among CCP enrollees. We then matched CCP to non-CCP persons on propensity for enrollment in the CCP, enrollment dates, and baseline viral load. Registry-based comparison group estimates were attenuated relative to pre-post estimates of program effectiveness. These methods have broad applicability for observational intervention effectiveness studies and programmatic evaluations for conditions with surveillance registries.

HIV-Related Stigma, Social Support, and Psychological Distress Among Individuals Initiating ART in Ethiopia.

Recent World Health Organization HIV treatment guideline expansion may facilitate timely antiretroviral therapy (ART) initiation. However, large-scale success of universal treatment strategies requires a more comprehensive understanding of known barriers to early ART initiation. This work aims to advance a more comprehensive understanding of interrelationships among three known barriers to ART initiation: psychological distress, HIV-related stigma, and low social support. We analyzed cross-sectional interview data on 1175 adults initiating ART at six HIV treatment clinics in Ethiopia. Experience of each form of HIV-related stigma assessed (e.g., anticipatory, internalized, and enacted) was associated with increased odds of psychological distress. However, among those who reported enacted HIV-related stigma, there was no significant association between social support and psychological distress. Interventions to improve mental health among people living with HIV should consider incorporating components to address stigma, focusing on strategies to prevent or reduce the internalization of stigma, given the magnitude of the relationship between high internalized stigma and psychological distress. Interventions to increase social support may be insufficient to improve the mental health of people living with HIV who experienced enacted HIV-related stigma. Future research should examine alternative strategies to manage the mental health consequences of enacted HIV-related stigma, including coping skills training.

Psychological distress, health and treatment-related factors among individuals initiating ART in Oromia, Ethiopia.

HIV diagnosis may be a source of psychological distress. Late initiation of antiretroviral therapy (ART) and treatment-related beliefs may intensify psychological distress among those recently diagnosed. This analysis describes the prevalence of psychological distress among people living with HIV (PLWH) and examines the association of recent HIV diagnosis, late ART initiation and treatment-related beliefs with psychological distress. The sample includes 1175 PLWH aged 18 or older initiating ART at six HIV clinics in Ethiopia. Psychological distress was assessed with Kessler Psychological Distress Scale. Scores ≥ 29 were categorized as severe psychological distress. Individuals who received their first HIV diagnosis in the past 90 days were categorized as recently diagnosed. Multivariable logistic regression modeled the association of recent diagnosis, late ART initiation and treatment-related beliefs on severe psychological distress, controlling for age, sex, education, area of residence, relationship status, and health facility. Among respondents, 29.5% reported severe psychological distress, 46.6% were recently diagnosed and 31.0% initiated ART late. In multivariable models, relative to those who did not initiate ART late and had longer time since diagnosis, odds of severe psychological distress was significantly greater among those with recent diagnosis and late ART initiation (adjusted OR [aOR]: 1.9 [95% CI 1.4, 2.8]). Treatment-related beliefs were not associated with severe psychological distress in multivariable models. Severe psychological distress was highly prevalent, particularly among those who were recently diagnosed and initiated ART late. Greater understanding of the relationship between psychological distress, recent diagnosis, and late ART initiation can inform interventions to reduce psychological distress among this population. Mental health screening and interventions should be incorporated into routine HIV clinical care from diagnosis through treatment.
