Background: Antiretroviral therapy (ART) adherence is still suboptimal among some key populations, highlighting the need for innovative tailored strategies. This randomized controlled trial (RCT) aimed to evaluate the effect of a differentiated digital intervention on ART adherence among men who have sex with men (MSM) living with HIV in China.Methods: The two-armed parallel RCT was conducted at one HIV clinic in Jinan of China from October 19, 2020, to June 31, 2021. Men were referred by health providers to join the study and then choose one of three digital strategies-text message, only instant message, or instant message plus social media. They were assigned in a 1:1 ratio to the intervention arm or control arm using block randomization, and inside each arm, there were three groups depending on the type of delivering the message. The groups were divided according to participants' preferred digital strategies. The intervention arm received ART medication messages, medication reminders, peer education, and involved in online discussion. The control arm received messages on health behavior and nutrition. The primary outcome was self-reported optimal ART adherence, defined as not missing any doses and not having any delayed doses within a one-month period. Secondary outcomes included CD4 T cell counts, viral suppression, HIV treatment adherence self-efficacy, and quality of life. Intention-to-treat analysis with generalized linear mixed models was used to evaluate the intervention's effect.Results: A total of 576 participants were enrolled, including 288 participants assigned in the intervention arm and 288 assigned in the control arm. Most were ≤ 40 years old (79.9%) and initiated ART ≤ 3 years (60.4%). After intervention, the proportion of participants achieving optimal ART adherence in the intervention arm was higher than in the control arm (82.9% vs 71.1%). The differentiated digital intervention significantly improved ART adherence (RR = 1.74, 95%CI 1.21-2.50). Subgroup analysis showed one-to-one instant message-based intervention significantly improved ART adherence (RR = 2.40, 95% CI 1.39-4.17).Conclusions: The differentiated digital intervention improved ART adherence among MSM living with HIV in China, which could be integrated into people living with HIV (PLWH) management and further promoted in areas where PLWH can access text messaging and instant messaging services.Trial Registration: ChiCTR2000041282.

Pre-exposure prophylaxis (PrEP) is an important and highly effective HIV prevention strategy, but its uptake remains low, particularly among marginalized populations at high risk of HIV. Innovative and community-driven promotion strategies, such as open contests, are needed to address disparities. This directed content analysis uses a PrEP-specific adaptation of the Information-Motivation-Behavioral Skills (IMB) model to identify themes related to PrEP use reflected in community-generated submissions (n = 73) from an open contest conducted to elicit crowdsourced health promotion messages on PrEP in Baltimore, Maryland. In addition to identifying eight of the themes from the adapted IMB model, this analysis also identified two novel salient themes in the motivation category: self-worth/self-love and self-care practice. Findings from this analysis can inform PrEP promotion efforts by pointing to salient themes identified from a community-driven approach that are less well represented in existing research.
