A new US study finds the biggest risk factor gay men face when it comes to acquiring HIV is whether they regularly use crystal meth.
The drug increases sexual risk-taking, among other effects. The study was published this month in the JAIDS (Journal of Acquired Immune Deficiency Syndromes).
It tracked almost 4,786 gay and bi men in the US over 12 months. The men, recruited through dating apps, were aged between 16-49 and were not on PrEP.
They were all tested for HIV at the start of the study and monthly thereafter. The study found: 2.5% (115) of those in the study acquired HIV during the 12 months.
