| Abstract: | INTRODUCTION: The Lifestyle for Brain Health (LIBRA) index evaluates modifiable dementia risk, mainly in midlife and older adults. We examined the frequency of LIBRA factors and their individual and combined associations with cognitive functioning across adulthood (20-75 years), considering age, sex, and socioeconomic status (SES). METHODS: Data came from the population-based German National Cohort (NAKO baseline; n = 149,948). We calculated proportions for LIBRA factors, tested frequency trends, and analyzed cross-sectional associations with cognitive functioning using cluster-adjusted regression controlling for confounders. RESULTS: Behavioral and psychosocial risks (smoking, physical inactivity, depression) were more common in younger adults, while cardiovascular risks (hypertension, coronary heart disease, hypercholesterolemia) predominated in older age. Men had higher LIBRA scores. Higher scores were consistently linked to lower cognitive functioning and lower SES across age groups. DISCUSSION: Dementia risk factors were frequent and already associated with poorer cognition in younger adults, underscoring the need for early, targeted, and equity-oriented prevention. |
