Neurocognitive Function Among Middle-aged and Older Hispanic/Latinos: Results from the Hispanic Community Health Study/Study of Latinos

We sought to examine and describe neurocognitive function among middle-aged and older Hispanic/Latino Hispanic Community Health Study/Study of Latinos (HCHS/SOL) participants. We analyzed baseline cross-sectional data from the middle-aged and older (ages 45–74 years old) participants (n = 9,063) to calculate neurocognitive function scores and their correlates. Older age and higher depressive symptoms scores were associated with lower average neurocognitive performance, whereas greater educational attainment and household income were associated with higher neurocognitive performance. Hispanic/Latino heritage groups significantly varied in neurocognitive performances. Some neurocognitive differences between Hispanics/Latinos were maintained after controlling for language preference, education, household income, and depressive symptoms. We found notable differences in neurocognitive scores between Hispanic/Latino heritage groups that were not fully explained by the cultural and socioeconomic correlates examined in this study. Further investigations into plausible biological and environmental factors contributing to the Hispanic/Latino heritage group differences in neurocognitive found in the HCHS/SOL are warranted

Describe prevalence and relationships to cardiovascular morbidity of depression, anxiety and medication use among Hispanic/Latinos of different ethnic backgrounds

Obstructive sleep apnea and neurocognitive function in a Hispanic/Latino population.

ObjectiveWe evaluated the association between obstructive sleep apnea (OSA) and neurocognitive function among community-dwelling Hispanic/Latino individuals in the United States.MethodsCross-sectional analysis of the Hispanic Community Health Study/Study of Latinos middle-aged and older adults, aged 45 to 74 years, with neurocognitive test scores at baseline measurements from 2008 to 2011. Neurocognitive scores were measured using the Word Fluency (WF) Test, the Brief-Spanish English Verbal Learning Test (SEVLT), and the Digit Symbol Substitution (DSS) Test. OSA was defined by the apnea-hypopnea index (AHI). Multivariable linear regression models were fit to evaluate relations between OSA and neurocognitive scores.ResultsThe analysis consisted of 8,059 participants, mean age of 56 years, 55% women, and 41% with less than high school education. The mean AHI was 9.0 (range 0-142; normal AHI <5/h). There was an association between the AHI and all 4 neurocognitive test scores: Brief-SEVLT-sum (β = -0.022) and -recall (β = -0.010), WF (β = -0.023), and DSS (β = -0.050) at p < 0.01 that was fully attenuated by age. In the fully adjusted regression model, female sex was a moderating factor between the AHI and WF (β = -0.027, p < 0.10), SVELT-sum (β = -0.37), SVELT-recall (β = -0.010), and DSS (β = -0.061) at p < 0.01.ConclusionOSA was associated with worse neurocognitive function in a representative sample of Hispanic/Latino women in the United States
