Assessing Alzheimer's Disease Knowledge and Cognitive Risk Among a Rural Older Afro-Caribbean Cohort.

PURPOSE: Older, rural Afro-Caribbeans are a growing subset of the Black population who face increased risk for Alzheimer's disease and related dementias (ADRD), but research targeting ADRD is scarce in this group. The purpose of this study was to investigate dementia risk among older Afro-Caribbeans living in a rural area. We also examined age, sex, and years of education, and knowledge about Alzheimer's disease as potential predictors of dementia risk. DESIGN: A pre-post, correlational design was employed. METHODS: Cognitive screenings were conducted using Nasreddine's Mini-MoCA, with tests of language fluency/orientation/recall, and linear regression analysis. A basic knowledge of Alzheimer's disease survey (BKAD) was also administered. FINDINGS: A total of 55 Afro-Caribbean participants (67.0 +10.8y (M ± SD), 65.5% with 10y or less of education residing in a rural area within the last 20 years were included.Over 50% of the convenience sample scored in the cognitive risk range. Significant associations were found between Mini-MoCA Total and Language scores and education (p < 0.01). Further, there was a significant change from pretest to posttest in BKAD scores. BKAD pretest and posttest scores were also significantly higher for those without dementia risk based on the Mini-MoCA Total. CONCLUSION: While the Mini-MoCA showed good reliability in less-educated older Afro-Caribbeans, scores were strongly dependent on years of education. Offering a limited intervention resulted in increased BKAD scores in this Afro-Caribbean sample, and a low BKAD score was associated with a higher dementia risk category. CLINICAL EVIDENCE: This study contributes to the limited but growing body of research about Alzheimer's disease knowledge, cognitive risk, and dementia detection among Afro-Caribbeans. The use of language-neutral cognitive assessments is recommended among rural older immigrants.

Bon Sante (Good Health): Factors Influencing PrEP Use Among Haitians/Haitian Americans.

BACKGROUND: The HIV/AIDS epidemic has disproportionately affected Black individuals in the USA, and this health disparity has increased over time. Despite the effectiveness of pre-exposure prophylaxis (PrEP) as a prevention tool for HIV, there are disparities in its use, and uptake of this intervention remains low among racial and ethnic minorities, including Haitians/Haitian Americans. In this study, factors influencing PrEP use among Haitians/Haitian Americans in Miami, FL, are explored to provide necessary data to address disparities. METHODS: The research team collaborated with local organizations to recruit 30 individuals (Haitians/Haitian Americans) between February 4 and October 1, 2021, and conducted semi-structured interviews. All interviews were audio-recorded and transcribed, and NVivo® was used to analyze the transcripts for emergent themes. RESULTS: The study sample comprised 30 adults of Haitian descent in Miami, FL (50% female, approximately 67% with a high school education or more, mean age = 43.7 ± 13 years, and 74.2% born in Haiti). Four primary themes emerged from the analysis: (1) limited PrEP awareness, (2) underutilization of PrEP, (3) inadequate discussion of HIV prevention strategies, and (4) PrEP delivery encompassing barriers and facilitators for PrEP delivery and promotion strategies. CONCLUSION: This study indicated that there is a critical need to increase Haitians/Haitian Americans' knowledge regarding PrEP. Health communication interventions tailored specifically for Haitians/Haitian Americans that target stigma, attitudes toward HIV, and risk perception may be significant in increasing PrEP in this population.

Exploring Reasons for Differential Vulnerability and Alzheimer's Disease Risk in Racial and Ethnic Minorities.

BACKGROUND: African American and Hispanic older adults are reported to have up to a 2-fold higher risk of Alzheimer's disease and related disorders (ADRD), but the reasons for this increased vulnerability have not been fully explored. The Vulnerability Index (VI) was designed to identify individuals who are at risk of developing cognitive impairment in the future, capturing 12 sociodemographic variables and modifiable medical comorbidities associated with higher ADRD risk. However, a prior limitation of the VI was that the original study cohort had limited diversity. We examined the association of the VI within and between non-Hispanic White, African American, and Hispanic older adults with and without cognitive impairment and different socioeconomic strata enrolled in a community-based dementia screening study. OBJECTIVE: To explore reasons for reported higher ADRD vulnerability in African Americans and Hispanics. METHODS: In a cross-sectional study of 300 non-Hispanic White, African American, and Hispanic older adults with and without cognitive impairment, we studied the association between cognitive status, the VI, and socioeconomic status (SES). RESULTS: When considering race/ethnicity, the presence of more vascular comorbidities drove greater vulnerability. When considering SES, vascular comorbidities played a less prominent role suggesting resources and access to care drives risk. The VI had differential effects on cognitive performance with the greatest effect in the earlier stages of impairment. CONCLUSION: Findings from this study provide a deeper understanding of the differential risk of ADRD in multicultural older adults captured by the VI and how barriers to healthcare access may increase vulnerability in racial/ethnic minorities.

Testing the Efficacy of an HIV Prevention Intervention Among Latina Immigrants Living in Farmworker Communities in South Florida.

Latina immigrants living in farmworker communities are a population in need of HIV risk reduction interventions due to their high risk for HIV and their limited access to health care and prevention services. The present study is the first to evaluate the efficacy of SEPA intervention on a cohort of 234 pre-established Latina immigrants living in farmworker communities in South Florida. SEPA is a CDC evidenced-based and Latinx culturally tailored HIV risk reduction intervention. Data were collected through structured interviews at baseline and 6-months post intervention and were analyzed using generalized linear mixed modeling. Results showed that SEPA was effective on increasing condom use during vaginal and anal sex with male partners, self-efficacy for condom use, intentions to negotiate safe sex and HIV-related knowledge from baseline to 6-months post intervention. These findings contribute to the evidence supporting the efficacy of SEPA by confirming previous results and demonstrating the efficacy of this intervention for Latinas of diverse backgrounds.
