Alcohol Reduction Interventions Show Promise for People Living with HIV, But Viral suppression Remains Unchanged
A recent study published in eClinicalMedicine reveals that while alcohol reduction interventions and incentives for isoniazid (INH) adherence improved health outcomes for people living with HIV (PWH), they did not significantly impact viral suppression rates. The research, which followed participants for a year, found that viral suppression remained consistently high regardless of the interventions.
Unhealthy alcohol use is a important concern for PWH, often linked to poor health outcomes and increased risk of tuberculosis (TB) in high-prevalence areas. The study aimed to evaluate whether financial incentives for reducing alcohol use and promoting INH adherence could sustain viral suppression six months after the incentives ended.
The trial, known as the Drinkers’ Intervention to Prevent Tuberculosis, included 680 participants aged 18 and older, all living with HIV and exhibiting unhealthy alcohol use. Participants were required to have a positive Alcohol Use Disorder Identification Test—Consumption score and a positive urine ethyl glucuronide test. Those with a history of active TB or pregnancy were excluded.
Participants were randomized into four groups: alcohol reduction incentives, no alcohol reduction incentives, INH adherence incentives, and no INH adherence incentives. After 12 months, 619 participants provided data on alcohol use and viral load. The results showed that 97.2% of participants maintained viral suppression, with minimal differences between the groups.| Group | Viral Suppression Rate |
|——————————–|—————————-|
| Alcohol Reduction Incentives | 96.7% |
| No Alcohol Reduction Incentives| 97.6% |
| INH Adherence Incentives | 98.3% |
| No INH Adherence Incentives | 96.0% |
The study also found that 71% of participants who reduced their alcohol use at 3 and 6 months maintained low-risk drinking at 12 months. However, only 6% of those who did not reduce alcohol use early on achieved low-risk drinking by the end of the study.
Despite these promising results, the study had limitations. Some participants did not complete the 12-month follow-up, and self-reported data on alcohol use and antiretroviral therapy (ART) adherence may have been affected by social desirability or recall bias.Additionally, the high baseline viral suppression among participants limited the ability to assess the interventions’ long-term impact.
The researchers concluded, “We found sustained lower levels of alcohol use at 12 months in the alcohol reduction intervention versus no alcohol intervention arms, suggesting that intervention effects persist after incentives are no longer provided.” This highlights the potential of such interventions to improve the overall health of PWH, even if viral suppression remains unchanged.

A recent study published in eClinicalMedicine reveals that while alcohol reduction interventions and incentives for isoniazid (INH) adherence improved health outcomes for people living with HIV (PWH), they did not considerably impact viral suppression rates. The research, which followed participants for a year, found that viral suppression remained consistently high nonetheless of the interventions.We spoke with Dr. Emily Carter, an expert in HIV and substance use, to delve deeper into the findings and their implications.
Understanding the Study’s Design and Objectives
Senior Editor: Dr. Carter, can you start by explaining the design of this study and what the researchers aimed to achieve?
dr. Emily Carter: Certainly. The study, known as the drinkers’ Intervention to Prevent Tuberculosis, involved 680 participants living with HIV who exhibited unhealthy alcohol use. The goal was to evaluate whether financial incentives for reducing alcohol consumption and promoting INH adherence coudl sustain viral suppression six months after the incentives ended. Participants were randomized into four groups: those receiving incentives for alcohol reduction, those without such incentives, those receiving incentives for INH adherence, and those without INH adherence incentives.
Senior Editor: what were the study’s most noteworthy findings regarding viral suppression and alcohol use reduction?
Dr. Emily Carter: The most striking finding was that 97.2% of participants maintained viral suppression after 12 months,with minimal differences between the intervention groups.This suggests that while incentives for alcohol reduction and INH adherence had other health benefits, they did not significantly impact viral suppression rates. However, the study did find that 71% of participants who reduced their alcohol use at 3 and 6 months maintained low-risk drinking at 12 months, compared to onyl 6% of those who did not reduce their alcohol use early on.
Implications for People Living with HIV
Senior Editor: How do these findings impact the approach to managing alcohol use among people living with HIV?
Dr. Emily Carter: These findings are important because they highlight the potential of alcohol reduction interventions to improve the overall health of people living with HIV, even if viral suppression remains unchanged. Unhealthy alcohol use is a critical concern for this population, as it is often linked to poor health outcomes and increased risk of tuberculosis in high-prevalence areas. The study underscores the importance of addressing both HIV and substance use concurrently to enhance overall well-being.
Limitations and Future Research
Senior Editor: what were the study’s limitations, and what further research is needed?
Dr.Emily Carter: One limitation is that not all participants completed the 12-month follow-up, and self-reported data on alcohol use and ART adherence could have been influenced by social desirability or recall bias. Additionally,the high baseline viral suppression among participants made it challenging to assess the long-term impact of the interventions. Future research should explore these interventions in settings with lower baseline viral suppression and consider objective measures to minimize bias.
Conclusion: the Path Forward
Senior Editor: what are the key takeaways from this study for healthcare providers and policymakers?
Dr. Emily Carter: The key takeaway is that alcohol reduction interventions can have sustained benefits for people living with HIV, even after the removal of financial incentives. While these interventions may not directly impact viral suppression, they play a crucial role in improving overall health outcomes. Healthcare providers should consider integrating alcohol reduction strategies into routine care for people living with HIV, and policymakers should support research and programs that address both HIV and substance use comprehensively.
