Identifying intervention opportunities in the continuum of cognitive impairment among persons aging with HIV - PROJECT SUMMARY / ABSTRACT Specific Aims: This proposal aims to identify opportunities to improve the prevention and mitigation of risks associated with cognitive impairment among people aging with HIV. Aim 1 will estimate the proportion of cognitive impairment cases potentially attributable to psychosocial and behavioral risk factors to prioritize those, which if intervened upon, could hypothetically result in the greatest prevention of cognitive impairment. Aim 2 will determine whether cognitive impairment increases the risk of losing one’s durable (sustained) viral suppression so we may mitigate this adverse outcome. Significance: As people with HIV (PWH) live longer due to treatment advances, they face a growing burden of age-related conditions, including cognitive impairment. PWH experience higher rates of cognitive impairment than people without HIV despite widespread viral suppression, which implicates non-HIV-related factors in their cognitive risk. Focusing on psychosocial and behavioral risk factors, which are prevalent in PWH and causally linked to cognitive impairment, can help to prioritize fruitful prevention strategies. In addition, cognitive impairment may threaten the durability of viral suppression, which could hinder cognitive maintenance and prevention of HIV transmission. Considering these issues in tandem can inform preparations for the long-term healthcare needs of people aging with HIV. Approach: These aims will leverage the Multicenter AIDS Cohort Study (MACS) (Aim 1), which includes 10 years of longitudinal cognitive screening data, and the Johns Hopkins HIV Clinical Cohort (JHHCC) (Aim 2), an urban cohort of PWH with rich clinical data. In Aim 1, we will estimate population attributable fractions for incident cognitive impairment, using longitudinal data and methods to account for time-varying risk factors, censoring, and competing risks. In Aim 2, we will employ a longitudinal closed cohort design to estimate the risk ratio for loss of durable viral suppression in PWH by cognitive impairment status. Training Information: The proposed research encompasses the dissertation of Madeline Brooks, a PhD student in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health. The training plan consists of coursework, mentorship, and professional development to support the successful completion of these aims and prepare Ms. Brooks to become an independent research epidemiologist. These aims address priorities of the NIH Office of AIDS Research to address the role of non-infectious comorbidities in central nervous system complications and subsequent implications for HIV transmission.
