"Me Dieron Vida": The Effects of a Pilot Health Promotion Intervention to Reduce Cardiometabolic Risk and Improve Behavioral Health among Older Latinos with HIV

Preventing Cognitive Decline in Older Latino Adults With HIV Through a Culturally Tailored Health Promotion Intervention: Protocol for a Single-Arm Pilot Trial

BACKGROUND

Older Latino adults with HIV are at increased risk for mild cognitive impairment and earlier onset of aging-related cognitive decline. Improvements in cognitive functioning and cognitive outcomes are possible among people with HIV who adopt health promotion behaviors. However, health promotion interventions for older Latino adults with HIV have not been extensively used or widely recognized as viable treatment options. Happy Older Latinos are Active (HOLA) is a multicomponent, health promotion intervention that is uniquely tailored for older Latino adults with HIV.

OBJECTIVE

This study aims to (1) determine the feasibility and acceptability of an adapted version of HOLA aimed at improving cognitive functioning among older Latino adults with HIV; (2) explore whether HOLA will produce changes in cognitive functioning; (3) explore whether HOLA will produce changes in activity, psychosocial functioning, or biomarkers of cognition; and (4) explore whether changes in activity, psychosocial functioning or cognitive biomarkers correlate with changes in cognition, while accounting for genetic risk for dementia.

METHODS

A single-arm pilot trial with 30 Latino (aged 50 years and older) men and women with HIV was conducted to assess feasibility, acceptability, and preliminary effects on cognition. Participants were assessed at 2 time points (baseline and postintervention) on measures of neurocognitive and psychosocial functioning. In addition, blood samples were collected to determine biomarkers of cognition at baseline and postintervention. Successful recruitment was defined as meeting 100% of the targeted sample (N=30), with 20% (n=6) or less of eligible participants refusing to participate. Adequate retention was defined as 85% (n=25) or more of participants completing the postintervention assessment and acceptability was defined as 80% (n=38) or more of sessions attended by participants.

RESULTS

Participant recruitment began on February 22, 2022, and was completed on August 15, 2022. The last study visit took place on February 20, 2023. Data analysis is currently ongoing.

CONCLUSIONS

Encouraging findings from this exploratory study may provide a blueprint for scaling up the HOLA intervention to a larger cohort of older Latino adults with HIV who may be currently experiencing or are at risk for HIV-related cognitive challenges.

Prioritizing recruitment: the benefits to using a disease registry to recruit older adults with HIV and intersecting identities

The success of a study hinges on its recruitment procedures, however there is a paucity of papers focused on innovative recruitment strategies, especially as it relates to the recruitment and retention of marginalized populations. This paper aims to outline how consent-to-contact databases can be used as an effective tool for recruitment. First, we begin by describing the consent-to-contact databases we used. Then, we offer insight into how a consent-to-contact database was utilized to recruit Latino older adults with HIV participants for an interdisciplinary behavioral and physical health promotion intervention. We outline barriers and challenges to recruitment and research participation with a specific emphasis on the unique hurdles associated with recruiting and retaining racial/ethnic minority older adults with HIV in behavioral health studies. Finally, we provide final recommendations for future researchers interested in how to best employ this type of recruitment tool in their own research.
