Socioeconomic status is identified as a critical confounding variable that must be controlled for when analyzing the relationship between sleep duration and cognitive outcomes, such as brain volume and executive function, as evidenced by [1], [2], and [3].

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.

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.

claimSleeping between six and eight hours remained predictive of higher brain volume in a regression model that controlled for baseline sleep characteristics, obstructive sleep apnoea traits, smoking, vascular co-morbidity, APOE ε status, body mass index, and socio-economic status.

claimA multiple regression model using Executive Function as the dependent variable confirmed a quadratic relationship between sleep duration and cognitive performance, controlling for age, chronotype, insomnia, obstructive sleep apnoea traits, vascular co-morbidity, smoking, BMI, APOE ε4 genotype, and socioeconomic status.
