Behavioral and Clinical Characteristics of Persons Living with Diagnosed HIV Infection—Medical Monitoring Project, United States, 2019 Cycle: Commentary
At year-end 2018, an estimated 1,040,352 persons in the United States and 6 dependent areas were living with diagnosed HIV infection . In 2019, the number of new HIV diagnoses was 37,881 . Although the National HIV Surveillance System (NHSS) collects information about persons with diagnosed HIV infection , other surveillance systems provide more detailed information about care seeking, health care use, use of ancillary services, and other behaviors . In 2005, in response to an Institute of Medicine (IOM) report outlining the need for representative data on persons with HIV , the Centers for Disease Control and Prevention (CDC) implemented the Medical Monitoring Project (MMP), which from 2009 to 2014 collected data from a 3-stage probability sample of adults receiving HIV medical care . In 2015, in response to recommendations stemming from an IOM review of national HIV data systems , MMP sampling and weighting methods were revised to include all adults with diagnosed HIV infection regardless of HIV care status. MMP is a cross-sectional, nationally representative, complex sample survey that assesses the behavioral and clinical characteristics of adults with diagnosed HIV infection in the United States. MMP also provides information on behaviors and clinical outcomes affecting the risk of HIV transmission, morbidity, and mortality that are critical for achieving the goals of the HIV National Strategic Plan  and the Ending the HIV Epidemic in the U.S. (EHE) initiative , which seeks to reduce new HIV infections in the United States by 90% by 2030.
The 2019 MMP sample was selected in 2 consecutive stages: (1) U.S. states, the District of Columbia, and Puerto Rico and (2) persons aged ≥18 years with diagnosed HIV infection reported to NHSS as of December 31, 2018. A total of 23 project areas from 16 states and Puerto Rico were funded to conduct data collection for the 2019 cycle (Table 1).
This report presents unweighted frequencies and weighted prevalence estimates with 95% confidence intervals for selected characteristics. The estimates describe the characteristics of adults with diagnosed HIV infection who are living in the United States, hereafter referred to as persons with diagnosed HIV or persons. The period referenced for estimates is the 12 months before the participants’ interviews and medical record abstractions unless otherwise noted. Statistical software (SAS, version 9.4) was used for analysis of weighted data . Data are not reported for estimates derived from a denominator size < 30 or with a coefficient of variation ≥ 0.30.
Estimates with an absolute confidence interval width ≥ 30, estimates with an absolute confidence interval width between 5 and 30 and a relative confidence interval width > 130%, and estimates of 0% or 100% are marked with an asterisk and should be interpreted with caution. No statistical tests were performed. Additional information on MMP is available at https://www.cdc.gov/hiv/statistics/systems/mmp/.
Highlights of Analyses
All 16 states, including 6 separately funded jurisdictions within those states, and the 1 territory sampled for MMP participated (Figure 1). In total, 9,700 persons were sampled from NHSS and 4,100 participated (Table 1). Adjusted for eligibility, the response rate was 45% (data not shown in table).
An estimated 75% of persons were male, 23% were female, and 2% were transgender (Figure 2; Table 2). Nearly half (46%) identified themselves as heterosexual or straight; 42% as lesbian or gay; 9% as bisexual; and 3% as another sexual orientation. An estimated 42% were Black or African American, 29% were White, and 22% were Hispanic or Latino. Nearly three-quarters (74%) were aged at least 40 years, and 68% had received an HIV diagnosis at least 10 years earlier.

The estimated average geometric mean CD4 count among all persons was 637 cells/µL, and the median geometric mean CD4 count was 602 cells/µL (range, 1–2,650) (data not shown in table).
An estimated 67% of persons had an undetectable (< 200 copies/mL) viral load at the most recent measurement, while 61% had undetectable viral loads at all measurements during the past 12 months (sustained viral suppression) (Figure 4; Table 3).

Self-reported ART Medication Use and Adherence
An estimated 98% of persons had ever taken ART and 94% of persons were currently taking ART, based on self-report (Table 7). Among the estimated 4% of persons with a history of ART use but who were not currently taking ART, 51% were not taking ART due to money or insurance problems and 29% were not taking ART because the person’s health care provider never discussed restarting ART with them (Table 7).

*Responses to the items on the PHQ-8 were used to define “major depression” and “other depression” according to criteria from the DSM-IV. “Major depression” was defined as having at least 5 symptoms of depression; “other depression” was defined as having 2–4 symptoms of depression. The PHQ-8 classification “other depression” comprises the DSM-IV categories of dysthymia and depressive disorder, not otherwise specified, which includes minor or subthreshold depression.
†Responses to the GAD-7 were used to define “mild anxiety,” “moderate anxiety,” and “severe anxiety,” according to criteria from the DSM-IV. “Severe anxiety” was defined as having a score of ≥ 15; “moderate anxiety” was defined as having a score of 10–14; and “mild anxiety” was defined as having a score of 5–9.
