Figure Lengend Snippet: Weighted distributions of sociodemographic, behavioral, health, and sleep characteristics among the analytic sample measured at Wave 2 in the National Social Life, Health and Aging Project (NSHAP) from August 2010 to May 2011 a .

Article Snippet: Both actigraph-measured sleep fragmentation (β = 0.02; 95% confidence interval [CI] = 0.01 to 0.04) and WASO (β = 0.26; 95% CI = 0.09 to 0.43) were significantly and positively associated with individual-level cortisol effects in the unadjusted models such that those with more sleep disruption showed higher levels of daytime cortisol ( ).

Techniques: Activity Assay, Modification

Unadjusted linear regression models of individual-level cortisol effect regressed on sleep measures for the National Sleep Life, Health and Aging (NSHAP) project Wave 2 from August 2010 to May 2011 a .
