Impact of sleep duration on executive function and brain structure nature.com Mar 3, 2022 8 facts
procedureThe researchers deconfounded age from the Executive Function measure by using age residuals within fixed-age quantile bins of 20% (7.1 years).
procedureMultiple regression analysis was used to test the relationship between sleep duration and the Executive Function latent variable while controlling for age, cardiovascular comorbidity, smoking pack years, BMI, genetic risk, and socioeconomic status.
claimIn the multiple regression model used in the study 'Impact of sleep duration on executive function and brain structure', age was the strongest predictor of Executive Function by an order of magnitude compared to other variables.
claimThe sliding window approach used to study the relationship between age, Executive Function, and sleep duration does not assume a linear relationship between variables.
claimThe multiple regression model examining the relationship between sleep duration and Executive Function controlled for age, sleep characteristics (chronotype, insomnia), obstructive sleep apnoea traits (daytime sleepiness, snoring), vascular co-morbidity, smoking, BMI, APOE ε4 genotype, and socioeconomic status.
procedureThe researchers applied a mean smoothing factor of one hour for sleep duration and two years for age when visualizing the relationship between sleep duration and Executive Function.
claimAge is the strongest predictor of Executive Function by an order of magnitude compared to other predictors in the regression model.
procedureThe researchers used a sliding window approach with an age window of fixed age-quantile widths and a smoothing Gaussian kernel of five to analyze the relationship between age, Executive Function, and sleep duration.
