Total Sleep Time Interacts With Age to Predict Cognitive Performance Among Adults.

ABSTRACT:

Study objectives

To investigate interactions between high and low amounts of sleep and other predictors of cognitive performance.

Methods

We used four cognitive tests to determine whether sleep time interacted with age, personal history of a memory problem, parental history of a memory problem, or personal concerns about memory and were associated with cognitive performance. Data were collected from an internet-based cohort study. We used an ordinary least squares regression with restricted cubic splines, controlling for demographic variables and comorbidities.

Results

We found significant nonlinear interactions between (1) total sleep time and age and (2) total sleep time and personal history of a memory problem and cognitive performance. Short and long sleep duratio
