Takeaway

  • Between 2008 and 2016, HIV diagnoses among men who have sex with men (MSM) increased annually by 3% among young persons, aged 13-29 years.
    • Rate is 4 times that of MSM aged >50 years.
  • Young blacks and Hispanics/Latinos accounted for disproportionate number of cases.
  • Diagnoses among MSM aged 30-49 years declined 4%, while rates stabilized among MSM >50 years.

Why this matters

  • MSM (especially younger, racial/ethnic groups) should be tested at least once yearly to reduce large numbers of HIV infections, initiate early treatment, and promote care linkage/adherence.
  • MSM testing negative should receive prevention services, including preexposure prophylaxis.

Key results

  • 236,150 MSM with HIV diagnoses; 45% (n=106,258) aged 13-29 years, 43% (n=100,857) aged 30-49 years, 12% (n=29,034) aged >50 years.
  • Annual percentage changes (APCs):
    • Ages 13-29 years: APC=2.9%, of which blacks accounted for 49%, Hispanics/Latinos 25%.
    • Ages 30-49 years, APC=−3.5%; blacks and Hispanics/Latinos each accounted for 28%.
    • Ages >50 years, APC stable (but increased in Asians [7.0%], Hispanics/Latinos [4.1%]); overall, blacks accounted for 25% of diagnoses.
  • Overall, number of MSM living with diagnosed HIV increased 4.5% annually.

Study design

  • National HIV Surveillance System report of age-driven HIV diagnosis, prevalence trends among MSM between 2008 and 2016.
  • Funding: CDC.

Limitations

  • Missing risk factor information.
  • Underestimations, duplicates.
