Abstract

It is unknown whether relations between early-life factors and overall health in later life apply to burden of cerebral small vessel disease (cSVD), a major cause of stroke and dementia. We explored relations between early-life factors and cSVD in the Lothian Birth Cohort, a healthy aging cohort. Participants were recruited at age 70 (N = 1091); most had completed a test of cognitive ability at age 11 as part of the Scottish Mental Survey of 1947. Of those, 700 participants had brain MRI that could be rated for cSVD conducted at age 73. Presence of lacunes, white matter hyperintensities, microbleeds, and perivascular spaces were summed in a score of 0-4 representing all MRI cSVD features. We tested associations with early-life factors using multivariate logistic regression. Greater SVD score was significantly associated with lower age-11 IQ (OR higher SVD score per SD age-11 IQ =.78, 95% CI 0.65-.95, p=.01). The associations between SVD score and own job class (OR higher job class, .64 95% CI.43-.5, p=. 3), age-11 deprivation index (OR per point deprivation score, 1.08, 95% CI 1.00-1.17, p=.04), and education (OR some qualifying education, .60 95% CI.37-.98, p=.04) trended towards significance (p
