County-level School Quality Education Measures During Ninth Grade and Brain Health Imaging Markers in Late Life.

ABSTRACT:

Objectives

Education quality varies across the United States, both by state and by race/ethnicity, and it is unclear what impacts, if any, this may have on the brain in later life. In this study, we investigated the association between ninth-grade county-level education quality and brain health in 2 racially/ethnically diverse cohorts of older adults (n = 450, ages 61 to 102).

Methods

Historical county-level measures of education quality (percentage attendance, teacher-student ratio, and term length) were linked to total gray matter volume, ventricular volume, hippocampal volume, white matter hyperintensities, free water, and fractional anisotropy using linear regression models with robust SEs, adjusting for demographic factors, childhood socioeconomic status, state history
