A recent study in Peru is shining a light on how technology can help address rising HIV rates among men who have sex with men (MSM). Researchers tested a smartphone app built for ecological momentary assessment (EMA)—a method that collects real-time, discreet data about daily health risk behaviors. The results, published earlier this week, are promising: over a 10-day field test, MSM with HIV using the app logged an impressive 93% compliance rate (93 out of 100 expected reports) and gave it a mean usability rating of 6.4 out of 7 (standard deviation 0.62). This suggests the new tool is not only feasible for real-world use, but also highly acceptable to its target users.
The Power of Real-Time, Private Tracking
Why does this matter? Peru has seen HIV incidence climb among MSM, despite ongoing prevention efforts. Stigma, risky behaviors, and low medication adherence remain key challenges. EMA via smartphones offers a unique solution—by allowing participants to log sensitive behaviors privately and in real time, it reduces the risk of recall bias and increases accuracy. Privacy is a big deal for many MSM living with HIV, making this high compliance rate even more noteworthy.
Smartphones aren’t just convenient; they’re powerful research tools. The app tested in Peru uploaded data via wireless networks, protected against data loss, and automatically timestamped and geocoded entries for better monitoring. Studies have shown that similar mobile tracking methods work well for collecting data on substance use and health behaviors among HIV-positive individuals globally.
Fitting Technology into Everyday Life
Participants in the Peruvian study rated the EMA app as both easy to use and useful, with most reporting high satisfaction. These are important metrics, especially as modern HIV therapy increasingly focuses on fitting seamlessly into daily routines. As one HIV care campaign puts it, quality of life often comes down to the “small, practical things”—like whether a therapy (or a tracking app) integrates smoothly into everyday life. With EMA apps, people living with HIV have a confidential way to track behaviors that might affect their health and treatment outcomes, making it easier to have tailored, productive conversations with their healthcare providers.
As mobile technology continues to evolve, its role in public health—and specifically in HIV prevention and care—looks set to expand. The Peruvian results suggest that well-designed apps can help overcome barriers of stigma and privacy, encouraging more MSM living with HIV to take an active role in their health.
