abstract = {The LIfestyle for BRAin Health (LIBRA) index is a
well-validated tool for assessing modifiable dementia risk
in midlife and older adults. Less is known about LIBRA in
younger adults. Thus, we investigated the occurrence of
LIBRA factors and associations between the LIBRA index and
cognitive functioning across adulthood, spanning ages 20 to
75. We considered variations by age decade, sex, and
socioeconomic status (SES).The data source was the
population-based mega-cohort 'German National Cohort'
(NAKO). Proportions and Cochran-Armitage trend tests were
calculated for 10 out of 12 LIBRA factors (coronary heart
disease, diabetes, hypercholesterolaemia, hypertension,
depression, obesity, smoking, physical inactivity, chronic
kidney disease, and low-to-moderate alcohol consumption; no
information available on healthy diet and high cognitive
activity). Cluster-adjusted (for study sites) linear
regression analysis was used to assess associations of LIBRA
scores and cognitive functioning (composite
neuropsychological test score), adjusted for age, age2, sex,
education, SES, employment status, marital status, household
size, migration status, and German language proficiency, for
the total and stratified samples.The analytical sample of
149,948 participants had a mean age of 50.1 (13.6) years;
$50.4\%$ were women, and education levels were high
$(56.2\%$ had tertiary education). Behavioural risk factors
(smoking, physical inactivity, depression) occurred more
frequently in younger adults, while risk factors related to
vascular health conditions (hypertension, diabetes, coronary
heart disease) were more common in older adults (Figure 1).
Higher LIBRA scores were consistently associated with lower
cognitive functioning across adulthood. An SES gradient in
LIBRA scores was observed across age decades and sexes
(Figure 2). Men had lower LIBRA scores, but associations
with cognitive functioning were more pronounced in women.Our
findings provide novel evidence suggesting that LIBRA is a
useful tool in younger adulthood (20-39 years), a group
still neglected in dementia risk research. Modifiable risk
factors were already frequent in this age range and
associated with lower cognitive functioning. The observed
sex/gender and socioeconomic disparities indicate compounded
disadvantages faced by lower SES groups and women,
emphasising the need for tailored, ideally early
interventions possibly targeting behavioural risk factors.
Longitudinal studies could help to disentangle life-course
dynamics of LIBRA factors and cognitive functioning.},
