AbstractBackground: Separate lines of research have linked hypertension and alcohol use disorder to cognition among adults. Despite known sex differences in both of these conditions, studies examining associations on cognition are limited. We aimed to determine whether hypertension impacts the relationship between alcohol use and everyday subjective cognition and whether sex moderates this relationship in middle-aged and older adults. Materials and Methods: Participants (N = 275) 50+ years of age, who reported drinking, completed surveys measuring alcohol use (Alcohol Use Disorder Identification Test consumption items), self-reported history of hypertension, and everyday subjective cognition (Cognitive Failures Questionnaire [CFQ]). Regression was used to test a moderated moderation model examining independent and interactive roles of alcohol use, hypertension, and sex on cognition (CFQ scores: total, memory, distractibility, blunders, and names). Analyses controlled for age, years of education, race, body mass index, smoking status, depressive symptoms, global subjective sleep quality, number of prescription medication used, and number of comorbid medical conditions. Results: Sex moderated the interactive associations of hypertension and alcohol use frequency on CFQ-distractibility. Specifically, in women with hypertension, more alcohol use was associated with greater CFQ-distractibility (B = 0.96, SE = 0.34, p = 0.005). Discussion: Sex moderates the interactive association of hypertension and alcohol use on some aspects of subjective cognition in mid-to-late life. In women with hypertension, alcohol use may exacerbate problems with attentional control. Further exploration of sex- and or gender-specific mechanisms underlying these is warranted.
