BACKGROUND: Hypertension control in Hispanics/Latinos lag behind general US trends by 10-15%. Intensive systolic blood pressure (SBP) management <120 mm Hg may significantly reduce morbidity/mortality risk in adults with hypertension; less is known about cognition. We investigated cross-sectional associations of cognition with observed hypertension control at currently recommended (SBP < 140 mm Hg) and more intensive (SBP < 120 mm Hg) levels using baseline data from the Hispanic Community Health Study/Study of Latinos.
METHODS: From this multicenter cohort study, we focused on 1,735 Hispanic/Latino men and women ages 45-74 years with hypertension and verified antihypertensive use. Verbal fluency, information processing speed, learning, and memory were tested in Spanish or English.
RESULTS: Separate linear regressions revealed that being on 1 vs. >1 antihypertensive medication was not associated with cognition; however, individuals with SBP controlled to currently recommended levels outperformed individuals with uncontrolled SBP on verbal fluency [Beta = 1.44 (0.52), P < 0.01] and information processing speed [Beta = 3.01 (0.89), P < 0.001] in age-adjusted regression analyses; only information processing speed remained significant (P < 0.05) after additional adjustments including acculturation, health insurance, and other cardiovascular disease risk factors. When regrouping individuals based on more intensive SBP control, individuals with levels <120 mm Hg outperformed individuals with higher SBP on verbal fluency regardless of adjustments (P < 0.01). More intensive rather than currently recommended levels of control associated with higher verbal fluency performance regardless of adjustments (P < 0.05).
CONCLUSIONS: Individual cognitive test scores related to distinct SBP management with more intensive management appearing more robust against confounders. While cognitive associations with hypertension in Hispanics/Latinos may be multifactorial, different levels of SBP control should be considered in future prospective intervention studies.
