The study aimed to examine the rate of HIV sero-conversion among men who have sex with men (MSM) in Beijing and identify related risk factors.
A cohort of 809 sero-negative MSM was monitored over 18 months, with follow-ups revealing varying HIV incidence rates: 5.47, 12.37, and 6.86 per 100 person-years at 6, 12, and 18 months, respectively.
Key risk factors for increased HIV incidence included being younger than 25, having multiple partners, lower income, and certain health conditions, highlighting the need for enhanced prevention strategies in this demographic.
