20-Year income volatility and cognitive function in the National Longitudinal Survey of Youth (1979) cohort: A replication and extension of CARDIA findings.

ABSTRACT: Grasset et al. previously reported that income volatility throughout early-to-mid adulthood (occurring during 1990-2010) in the CARDIA cohort was associated with worse midlife cognitive function. However, CARDIA lacked earlier-life cognition data, a major potential confounder. We replicate and extend this study in the National Longitudinal Survey of Youth (1979), which collected cognition measures in approximate adolescence. Following Grasset, we estimated associations between 20-year income volatility throughout early-to-mid adulthood (mean ages 27-47 in 1990-2010) and midlife cognitive function using confounder-adjusted linear regression models. Income volatility was assessed as the standard deviation (SD) of the percent change in income between successive annual or biennial surveys and
