Prevalence of Diagnosed and Undiagnosed Depression Among US Adults with Human Immunodeficiency Virus: Data from the Medical Monitoring Project.

People with human immunodeficiency virus (PWH) are disproportionately affected by depression, but the recent national estimates for US PWH encompassing both current symptoms and clinical diagnoses to assess missed diagnoses and lack of symptom remission are lacking. We used data from CDC's Medical Monitoring Project (MMP) to report nationally representative estimates of diagnosed and undiagnosed depression among US adult PWH. During June 2021 to May 2022, MMP collected interview data on symptoms consistent with major or other depression and depression diagnoses from medical records of 3928 PWH. We report weighted percentages and prevalence ratios (PRs) to quantify differences between groups on key social and health factors. Overall, 34% of PWH experienced any depression (diagnosis or Patient Health Questionnaire-8); of these, 26% had symptoms but no diagnosis (undiagnosed depression), 19% had both diagnosis and symptoms, and 55% had a diagnosis without symptoms. Among those with depression, persons with a disability (PR: 1.52) and food insecurity (PR: 1.67) were more likely to be undiagnosed. Unemployed persons (PR: 1.62), those experiencing a disability (PR: 2.78), food insecurity (PR: 1.46), or discrimination in human immunodeficiency virus (HIV) care (PR: 1.71) were more likely to have diagnosed depression with symptoms. Those with symptoms (undiagnosed or diagnosed) were less likely to be antiretroviral therapy (ART) dose adherent (PR: 0.88; PR: 0.73) or have sustained viral suppression (PR: 0.62; PR: 0.91) and were more likely to have unmet needs for mental health services (PR: 2.38, PR: 2.03). One-third of PWH experienced depression, of whom nearly half were undiagnosed or still experiencing clinically relevant symptoms. Expanding screening and effective treatment for depression could improve quality of life and HIV outcomes.

A resting state EEG study on depressed persons with suicidal ideation.

Background: Major Depressive Disorder (MDD) is a psychiatric illness that is often associated with potentially life-threatening physiological changes and increased risk for suicidal behavior. Electroencephalography (EEG) research suggests an association between depression and specific frequency imbalances in the frontal brain region. Further, while recently developed technology has been proposed to simplify EEG data acquisition, more research is still needed to support its use in patients with MDD. Methods: Using the 14-channel EMOTIV EPOC cap, we recorded resting state EEG from 15 MDD patients with and MDD persons with suicidal ideation (SI) vs. 12 healthy controls (HC) to investigate putative power spectral density (PSD) between-group differences at the F3 and F4 electrode sites. Specifically, we explored 1) between-group alpha power asymmetries (AA), 2) between-group differences in delta, theta, alpha and beta power, 3) between PSD data and the scores in the Beck's Depression Inventory-II (BDI-II), Beck's Anxiety Inventory (BAI), Reasons for Living Inventory (RFL), and Self-Disgust Questionnaire (SDS). Results: When compared to HC, patients had higher scores on the BAI (p = 0.0018), BDI-II (p = 0.0001) or SDS (p = 0.0142) scale and lower scores in the RFL (p = 0.0006) scale. The PSD analysis revealed no between-group difference or correlation with questionnaire scores for any of the measures considered. Conclusions: The present study could not confirm previous research suggesting frequency-specific anomalies in depressed persons with SI but might suggest that frontal EEG imbalances reflect greater anxiety and negative self-referencing. Future studies should confirm these findings in a larger population sample.

Attitudes and Beliefs About HIV Treatment as Prevention Among People Who are Not Engaged in HIV Care, 2018-2019.

Treatment as prevention (TasP) is an effective HIV prevention strategy. Our objectives were to explore TasP attitudes and beliefs among people with HIV (PWH) who are not engaged in care and to examine attitudes and beliefs by selected characteristics. We sampled PWH who had participated in the Medical Monitoring Project (MMP), a structured interview survey, from June 2018-May 2019 to participate in 60-minute semi-structured telephone interviews. We obtained sociodemographic and behavioral quantitative data from the MMP structured interview. We used applied thematic analysis to analyze the qualitative data and integrated the qualitative and quantitative data during analysis. Negative attitudes and beliefs, especially skepticism and mistrust, about TasP were pervasive. Only one participant who identified as female, was not sexually active, and had not heard of TasP held positive attitudes and beliefs about TasP. TasP messages should use clear and unambiguous language, address mistrust, and reach people who are not engaged in medical care.

Using Semistructured Telephone Interviews to Collect Qualitative Data From People With HIV Who Are Not in Medical Care: Implementation Study.

BACKGROUND: The Medical Monitoring Qualitative (MMP-Qual) Project was designed to collect qualitative data from people with HIV not engaged in medical care that would complement quantitative data collected by the Medical Monitoring Project (MMP)-a national surveillance system-and inform the MMP's recruitment and data collection methods. OBJECTIVE: Our objectives were to describe the methodology of this project, reflect on the challenges and lessons learned from conducting qualitative telephone interviews at a national level, and describe how we used and plan to use the qualitative data to evaluate our recruitment procedures and quantitative data collection instrument as well as knowledge of HIV care engagement. METHODS: We used stratified purposive sampling to identify and recruit participants who had participated in the structured MMP interview into the MMP-Qual Project. To be eligible, participants must have had an HIV diagnosis, be aged ≥18 years, have lived in an MMP jurisdiction, and have not been engaged in HIV medical care. From August 1, 2018, to May 31, 2019, we conducted semistructured telephone interviews with 36 people with HIV across the United States about several topics (eg, facilitators and barriers to care and experience with surveys). Four trained interviewers conducted semistructured 60-minute telephone interviews with 36 participants. Data collection lasted from August 1, 2018, to May 31, 2019. RESULTS: From 2018 to 2019, 113 people were eligible to participate in the MMP-Qual Project. Of the people recruited, 28% (22/79) refused to participate. Of those who agreed to participate, 63% (36/57) were interviewed, and 37% (21/57) were no-shows. Of the 34 participants for whom we had complete data, 15 (44%) were aged ≥50 years, 26 (76%) identified as male, 22 (65%) were Black or African American, and 12 (35%) lived in the Southern United States. CONCLUSIONS: We learned that it is possible to obtain rich qualitative data from people with HIV who are not in care via telephone interviews and that this mode might be conducive to talking about sensitive topics. We also learned the importance of flexibility, communication, and coordination because we relied on health department staff to perform recruitment and had difficulty implementing our original sampling strategy. We hope that other projects will learn from our experience conducting qualitative telephone interviews with people with HIV on a national level.

The Boundary of HIV Care: Barriers and Facilitators to Care Engagement Among People with HIV in the United States.

Treating people with HIV (PWH) quickly and effectively to achieve viral suppression is a key strategy for Ending the HIV Epidemic. Understanding barriers and facilitators to HIV care engagement could improve outcomes among PWH and reduce HIV infections. We sampled PWH who participated in the Medical Monitoring Project from June 2018 to May 2019 and were not engaged in HIV care to participate in 60-min semistructured telephone interviews on barriers and facilitators to HIV care engagement. We used applied thematic analysis and placed codes into themes based on their frequency and salience. Participants reported various intrapersonal, health system, and structural barriers to care. We conceptualize the boundary of care as the space between the stages of the HIV care continuum, where PWH may find themselves when they lack intrapersonal, health system, and structural support. Research and interventions tackling these barriers are needed to improve outcomes among PWH and reduce HIV infections.

Assessing concordance of HIV risk behaviors collected by different surveillance systems.

OBJECTIVES: Assess concordance of assigned transmission category between National HIV Surveillance System (NHSS) and Medical Monitoring Project (MMP); assess persistence of behaviors by comparing transmission category to current behavior. DESIGN: Retrospective analysis of HIV surveillance data. METHODS: For 4034 participants in the 2016 MMP cycle, transmission category was assigned in NHSS and MMP by applying a hierarchy to acquisition risk behaviors and selecting the most likely risk behavior that led to HIV acquisition. We assessed concordance of transmission category between systems, the number of persons with an updated transmission category in NHSS after incorporating MMP data, and concordance of transmission category and current behavior. RESULTS: Concordance of transmission category between NHSS and MMP was 87% for men with evidence of male-to-male sexual contact and ranged from 27% to 62% in persons with other transmission categories. Transmission category in NHSS was updated for 9% of persons after incorporating MMP data, mostly affecting those with no identified risk in NHSS. Current behavior aligned with updated NHSS transmission category in 56% of men with a transmission category of male-to-male sexual contact. However, only 8% of men and 5% of women with a transmission category of injection drug use had recently injected drugs. CONCLUSION: HIV surveillance systems can better inform prevention efforts with more complete risk information. Sexual behaviors are more persistent over time than injection drug use. In addition to promoting viral suppression, routinely assessing risk and tailoring prevention activities accordingly can improve health outcomes.

National Clinical Programme for Eating Disorders: a pragmatic review of a new national eating disorder service in Ireland.

OBJECTIVE: The Health Service Executive National Clinical Programme for Eating Disorders (NCPED) launched a Model of Care for Eating Disorder Services in Ireland in 2018. Currently, one adult and two child and adolescent eating disorder services are operational out of a total of sixteen recommended. The three objectives of this paper are to describe the early (1) referral pattern, (2) level of service activity and (3) the level of service user satisfaction. METHOD: Monthly submitted service activity data from each service to the NCPED between March 2018 and October 2020 were retrospectively analysed. One hundred and fifty-nine carers and service users completed an experience of service questionnaire (ESQ). A descriptive analysis of referral pattern, level of service activity and ESQ was performed. A thematic analysis was performed on three qualitative questions on the ESQ. RESULTS: There was substantial referral numbers to eating disorder services by 18 months (n = 258). The main referral source was community mental health teams. The majority (n = 222, 86%) of referrals were offered an assessment. The most common age profile was 10-17 years of age (n = 120, 54.1%), and anorexia nervosa was the most common disorder (n = 96, 43.2%). ESQ results demonstrate that most service users were satisfied with their service, and the main themes were carer involvement, staff expertise, therapeutic alliance and service access. CONCLUSIONS: This preliminary service activity and service user satisfaction data highlight several issues, including trends when setting up a regional eating disorder service, potential pitfalls of pragmatic data collection and the need for adequate information-technology infrastructure.

Characteristics of Adults With Diagnosed HIV Who Experienced Housing Instability: Findings From the Centers for Disease Control and Prevention Medical Monitoring Project, United States, 2018.

ABSTRACT: People living with HIV (PLWH) who experience homelessness have poorer clinical outcomes than people with HIV who are not homeless; however, there is limited information on PLWH who experience other forms of housing instability. We used interviews and medical record abstraction data from the Medical Monitoring Project, collected 2018-2019 (N = 4,050), to describe sociodemographic characteristics and clinical outcomes of adults with HIV by whether people experienced unstable housing in the past 12 months. Overall, 21% were unstably housed, of which 55.2% were unstably housed but not homeless. People who were unstably housed were more likely to be younger, have lower educational attainment, be previously incarcerated, live at or below the poverty level, and have poorer mental health and clinical outcomes, independent of homelessness. Interventions to address housing instability, integrated with clinical care, could benefit not just PLWH who are homeless but also those who are unstably housed.

Sociodemographic Correlates of Self-reported Discrimination in HIV Health Care Settings Among Persons With Diagnosed HIV in the United States, Medical Monitoring Project, 2018-2019.

BACKGROUND: HIV-related discrimination in health care settings is associated with negative health outcomes among persons with HIV (PWH). This article describes and compares differences in the prevalence of self-reported experiences with discrimination in health care settings by sociodemographic and clinical care factors among persons with diagnosed HIV in the United States. METHODS: We analyzed interview and medical record data collected during June 2018-May 2019 from 3850 PWH who had received HIV care in the past 12 months. We calculated weighted percentages and associated 95% confidence intervals and assessed the association between any experience of discrimination and selected sociodemographic and clinical characteristics using prevalence ratios with predicted marginal means. RESULTS: Approximately 25% of PWH who had an HIV care visit in the past 12 months reported experiencing any discrimination. Experiences with discrimination were significantly more prevalent among persons aged 18-29 years (34%); transgender persons (41%); persons of gay (25%), bisexual (31%), or other (40%) sexual orientations; and persons who did not have a regular provider (39%), lived at/below poverty level (28%), were homeless (39%) or incarcerated (37%) in the past 12 months. PWH who experienced discrimination were more likely to have missed at least one HIV care visit, not be taking antiretroviral therapy, and have missed antiretroviral therapy doses. Recent and sustained viral suppression were not significantly associated with experiencing any discrimination. CONCLUSIONS: Interventions that address the sociocultural and structural factors associated with discrimination in all health care settings are needed to improve health outcomes among PWH and end the HIV epidemic in the United States.

Intimate Partner Violence Experienced by Adults With Diagnosed HIV in the U.S.

INTRODUCTION: Intimate partner violence is associated with adverse health consequences among people with diagnosed HIV, which could have implications for disease progression and transmission. However, nationally representative estimates of intimate partner violence among people with diagnosed HIV are lacking. Investigators used nationally representative data to estimate the prevalence of physical violence by an intimate partner among adults with diagnosed HIV and examine the differences by selected characteristics. METHODS: This analysis included interview and medical record data from the 2015-2017 cycles of the Medical Monitoring Project, analyzed in 2019. Weighted percentages and 95% CIs were used to report the prevalence of intimate partner violence among people with diagnosed HIV (N=11,768). Bivariate and multivariate differences in intimate partner violence by sociodemographic, behavioral, and clinical characteristics were examined using Rao-Scott chi-square tests (p<0.05). RESULTS: Among people with diagnosed HIV, 26.3% reported having ever experienced intimate partner violence, and 4.4% reported having experienced intimate partner violence in the past 12 months. The prevalence of intimate partner violence differed by gender and gender/sexual identity. People who experienced intimate partner violence in the past 12 months were more likely to engage in behaviors associated with elevated HIV transmission risk and have unmet needs for supportive services. People who recently experienced intimate partner violence were less likely to be engaged in routine HIV care but were more likely to seek emergency care services and have poor HIV clinical outcomes. CONCLUSIONS: This study's findings support the need for screening people with diagnosed HIV for intimate partner violence and offering linkage to supportive services. Screening for intimate partner violence among people with diagnosed HIV, coupled with supportive services and counseling, may lead to improved safety and HIV clinical outcomes and decreased need for emergency and inpatient medical services.

Barriers to HIV Care by Viral Suppression Status Among US Adults With HIV: Findings From the Centers for Disease Control and Prevention Medical Monitoring Project.

ABSTRACT: Failure to maintain viral suppression may be attributed to suboptimal care engagement. Using data collected during 2015-2018, we describe nationally representative estimates of engagement in care among US adults with diagnosed HIV, overall and by viral suppression. Of those who felt they did not receive enough care, we described detailed information on barriers to care by viral suppression. We reported weighted percentages and evaluated differences between groups using Rao-Scott chi-square tests (p < .05). Persons who were not virally suppressed were less likely to be retained in care (57.3 vs. 90.8%). Common barriers to care included life circumstances that impeded receipt of care (50.0%), financial barriers (34.5%), and not feeling sick enough to take medicine (32.0%). Barriers to care varied by viral suppression status, and people who were not virally suppressed were more likely to report more than one barrier to care. These findings demonstrate that barriers can be multifaceted; addressing barriers to care by expanding comprehensive care models in HIV care settings could improve clinical outcomes among people with HIV.

Limited English proficiency among adults with HIV in the United States - Medical Monitoring Project, 2015-2018.

Research suggests that language barriers in health care settings may adversely affect clinical outcomes and patient satisfaction. We describe the characteristics of adults with limited English proficiency (LEP) and diagnosed HIV in the United States. The Medical Monitoring Project is a complex sample survey of adults with diagnosed HIV in the United States that uses two-stage, probability-proportional-to-size sampling. We analyzed weighted interview and medical record data collected from June 2015-May 2018. The prevalence of LEP among adults with HIV was 10%. Higher percentages of adults with LEP, compared with adults with English proficiency (EP), were female, Hispanic/Latino, less educated and poor, only had Ryan White HIV/AIDS Program (RWHAP) health care coverage, attended RWHAP-funded facilities, were satisfied with their HIV medical care, were prescribed antiretroviral therapy (ART), were virally suppressed and received testing for sexually transmitted diseases. We found no statistical difference in ART adherence among adults with LEP and EP. Despite the association between LEP and the risk for health disparities, more persons with LEP were virally suppressed compared with persons with EP. One possible explanation is attendance at RWHAP-funded facilities by adults with LEP; however, future studies are needed to explore other possible explanations.

Disability among adults with diagnosed HIV in the United States, 2017.

In the United States, one in four adults is living with a disability. Age-related changes, disease-related pathology and treatments can place a person with HIV at risk for a disability. We analyzed nationally representative data to describe disability status among adults ≥18 years with diagnosed HIV in the United States and Puerto Rico by demographic characteristics, health behaviors, quality of care, clinical outcomes and mental health status. We reported weighted percentages and prevalence ratios with predicted marginal means to evaluate significant differences between groups (P < .05). Overall, 44.5% reported any disability; the most frequently reported disabilities were related to mobility (24.8%) and cognition (23.9%). Persons who lived in households at or below the poverty level or who experienced homelessness in the last 12 months reported a higher prevalence of any disability than persons who were not poor or not homeless (60.2% vs. 33.4% and 61.8% vs. 42.8%, respectively). Prevalence of depression and anxiety was higher among persons with any disability compared with those with no disability (32.8% and 26.6% versus 10.1% and 7.0%, respectively). Enhancing support from clinicians and ancillary providers may help optimize long-term health outcomes among HIV-positive persons with disabilities.

Using Resting State Heart Rate Variability and Skin Conductance Response to Detect Depression in Adults.

Depression is the leading cause of disability worldwide, yet rates of missed- and mis-diagnoses are alarmingly high. The introduction of objective biomarkers, to aid diagnosis, informed by depression's physiological pathology may alleviate some of the burden on strained mental health services. Three minutes of eyes-closed resting state heart rate and skin conductance response (SCR) data were acquired from 27 participants (16 healthy controls, 11 with major depressive disorder (MDD)). Various classifiers were trained on state-of-the-art and novel features. We are aware of no previous studies analysing the utility of multimodal vs. individual modalities for classification. We found no improvement using multimodal classifiers over using heart rate variability (HRV) alone, which achieved 81% test accuracy. The best multimodal and SCR only classifiers were only slightly less accurate at 78%. Despite not improving depression detection, SCR features did show stronger correlation with suicidal ideation than HRV. SD1/SD22 is a novel HRV feature proposed in this paper, similar to the commonly used ratio SD1/SD2 but with more marked separation between classes, having the largest Rank Biserial Correlation of all examined features (p-value = 0.002, RBC = -0.73). We recommend further studies in this area.

Is Patient Navigation Used by People with HIV Who Need It? An Assessment from the Medical Monitoring Project, 2015 - 2017.

We (1) estimated the prevalence of not getting patient navigation despite feeling a need for the service (unmet subjective need) or despite having unsuppressed viral load (unmet objective need) among people with HIV (PWH), (2) determined reasons why PWH did not use the service, and (3) determined factors associated with unmet need for patient navigation. We used combined data from the 2015 to 2017 cycles of the Medical Monitoring Project, an HIV surveillance system designed to produce nationally representative estimates of the characteristics of adults with diagnosed HIV infection in the United States. Six percent reported unmet subjective need and 28% had unmet objective need for patient navigation. When needs were combined, more than a third had unmet need for the service. Among PWH with unmet subjective need for patient navigation, 77% reported lack of knowledge about patient navigation as a reason for nonuse. Younger age, female gender, racial/ethnic minority status, limited health literacy, homelessness, incarceration history, lack of health insurance/coverage, noninjection drug use, depression, and recent HIV diagnosis were associated with unmet subjective or objective need for patient navigation. One in three PWH did not use patient navigation despite needing the service. Lack of knowledge about patient navigation was a barrier to use, calling for increased availability, and promotion of such services. PWH with social and economic vulnerabilities were less likely to get patient navigation when needed. It is important to address the question of how to make this service available to everyone who needs it.

Characteristics of Sexual Partnerships Among Men With Diagnosed HIV Who Have Sex With Men, United States and Puerto Rico-2015-2019.

BACKGROUND: Understanding sexual partnerships of HIV-positive persons, particularly at the dyad level, can help in quantifying HIV transmission risk. We described sexual partnerships among HIV-positive men who have sex with men (MSM), including partnerships with a high risk for sexual HIV transmission. SETTING: The Medical Monitoring Project is an annual, cross-sectional study that reports representative estimates on U.S. HIV-positive adults. METHODS: During 2015-2019, we assessed sexual behaviors by interview, and viral load results from medical records. Among sexually active HIV-positive MSM (n = 4923), we described prevalence of high-risk sex, defined as: (1) not having sustained viral suppression, and (2) having condomless sex with an HIV-negative partner not known to be taking pre-exposure prophylaxis or an HIV-unknown partner. We described sexual partnerships among HIV-positive MSM (n = 13,024 partnerships among 4923 MSM). For HIV-discordant partnerships (n = 7768), we reported the proportion involved in high-risk sex, and associations with high-risk sex using prevalence ratios with predicted marginal means, controlling for age of the HIV-positive partner (P < 0.05). RESULTS: More than half (66%) of sexually active HIV-positive MSM had condomless sex; 11% had high-risk sex. Blacks were more likely to have detectable viral loads, but less likely to have condomless sex, making prevalence of high-risk sex comparable between racial/ethnic groups. Dyad-level analyses among HIV-discordant partnerships indicated that prevalence of high-risk sex was higher among partnerships with HIV-positive white MSM, which was not observed using person-level data alone. CONCLUSIONS: In the context of ending the HIV epidemic, behavioral and clinical surveillance data can help monitor HIV transmission risk and target prevention efforts to reduce transmission among populations at disproportionate risk.

Reported preexposure prophylaxis use among male sex partners of HIV-positive men: 2016-2018.

OBJECTIVE: To estimate the proportion of US HIV-positive men who report a male HIV-negative/unknown status (HIV-discordant) sexual partner taking preexposure prophylaxis (PrEP), and the use of multiple HIV prevention strategies within partnerships. DESIGN: The Medical Monitoring Project is a complex sample survey of US adults with diagnosed HIV. METHODS: We used data collected during June 2016 to May 2018 among sexually active HIV-positive men who had at least one HIV-discordant male partner (N = 1871) to estimate the weighted prevalence of reporting at least one partner taking PrEP. Among HIV-discordant partnerships (N = 4029), we estimated PrEP use, viral suppression among HIV-positive partners, and condomless anal sex. We evaluated significant (P < 0.05) differences between groups using prevalence ratios with predicted marginal means. RESULTS: Twenty-eight percent of sexually active HIV-positive MSM reported at least one HIV-discordant male partner taking PrEP. Twenty percent of HIV-discordant partners were reported to be taking PrEP; 73% were taking PrEP or the HIV-positive partner was virally suppressed. PrEP use was lower among black and Hispanic partners compared with white partners (12% and 19% vs. 27%). Fewer black than white MSM were in partnerships in which PrEP was used or the HIV-positive partner had sustained viral suppression (69% vs. 77%). Condomless anal intercourse was more prevalent in partnerships involving PrEP use and in partnerships involving either PrEP use or sustained viral suppression among the HIV-positive partner. CONCLUSION: PrEP use was reported among one in five partners, with disparities between black and white partners. Increasing PrEP use and decreasing racial/ethnic disparities could reduce disparities in HIV incidence and help end the US HIV epidemic.

Mental health, substance use and HIV risk behaviors among HIV-positive adults who experienced homelessness in the United States - Medical Monitoring Project, 2009-2015.

Homelessness is a challenge to retention in HIV care and adherence to antiretroviral therapy. We describe the sociodemographic and behavioral characteristics of HIV-positive adults who reported recent homelessness. The Medical Monitoring Project is a complex sample survey of HIV-positive adults receiving medical care in the United States. We used weighted interview and medical record data collected from June 2009 to May 2015 to estimate the prevalence of depression, substance use, and HIV risk behaviors among adults experiencing recent homelessness. From 2009 to 2015, 8.3% of HIV-positive adults experienced recent homelessness. Homeless adults were more likely than housed adults to have major depression, to binge drink, use non-injection drugs, use injection drugs, and smoke. Over 60% of homeless adults were sexually active during the past year, with homeless adults reporting more condomless sex with an HIV-negative or unknown status sex partner than housed adults. Programs attempting to improve the health outcomes of HIV-positive homeless persons and reduce ongoing HIV transmission can focus on providing basic needs, such as housing, and ancillary services, such as mental health counseling or substance abuse treatment and counseling.

Socioeconomic, Behavioral, and Clinical Characteristics of Persons Living with HIV Who Experience Homelessness in the United States, 2015-2016.

Homelessness is a substantial barrier to consistent, recommended HIV care, access and adherence to antiretroviral therapy (ART), and sustained viral suppression, thus increasing the risk for morbidity and transmission. We used data from the Medical Monitoring Project for June 1, 2015-May 31, 2017 to estimate the weighted prevalence of homelessness among persons with diagnosed HIV (PWH) (N = 7665) overall and by selected sociodemographic, behavioral, and clinical characteristics. Prevalence of homelessness was 8.5%. PWH experiencing homelessness were > 3 times as likely to have needed and not received shelter or housing services (32% vs. 10%), > 4 times as likely to inject drugs (9% vs. 2%), and > 7 times as likely to engage in exchange sex (10% vs. 1%), respectively, compared with PWH who did not experience homelessness. Homelessness was associated with lower HIV care retention, ART dose adherence, and sustained viral suppression. This analysis demonstrates substantial need for enhanced treatment, care, and service delivery for PWH experiencing homelessness. Research has demonstrated that housing assistance programs improve HIV-related outcomes and diminish HIV risk behaviors; therefore, housing assistance for PWH should be prioritized in public health policies and practice.

A National Behavioral and Clinical Surveillance System of Adults With Diagnosed HIV (The Medical Monitoring Project): Protocol for an Annual Cross-Sectional Interview and Medical Record Abstraction Survey.

BACKGROUND: The Medical Monitoring Project (MMP) is a national population-based behavioral and clinical surveillance system of adults with diagnosed HIV in the United States, and it is sponsored by the Centers for Disease Control and Prevention (CDC). Its purpose is to provide locally and nationally representative estimates of factors affecting HIV transmission risk and clinical outcomes. OBJECTIVE: This study aimed to describe the rationale for and methodology of the MMP, in addition to its contribution to evaluating and monitoring HIV prevention, care, and treatment efforts in the United States. METHODS: MMP employs a stratified 2-stage sample design to select annual samples of persons living with diagnosed HIV from the National HIV Surveillance System and conducts interviews and medical record abstractions with participating persons. RESULTS: MMP data are published routinely via annual reports, conference presentations, and scientific publications. Data may be accessed upon request from the CDC, contingent on the guidelines established for the security and confidentiality of HIV surveillance data. CONCLUSIONS: MMP is the only source of annual population-based data on the behaviors and clinical care of persons with diagnosed HIV in the United States. It provides essential information for monitoring progress toward national treatment and prevention goals and guiding efforts to improve the health of persons with diagnosed HIV and prevent HIV transmission.
