Corrigendum to “Socioeconomic status in childhood predicts sleep continuity in adult Black and White men” Sleep Health. 4 (2018) 49–55

      The authors regret that three men should not have been included in the data set because of malfunctioning actigraphs and that some decision rules for scoring the actigraphy for sleep intervals and naps had not been followed consistently. Table 3, Table 5 present results that have been corrected after rescoring all actigraphy data and removal of three participants with suspect data. The corrected model 1 Table 5 shows that men who had lower socioeconomic status (SES) at age 7 and smaller increases in SES from ages 7 to 16 years had more minutes awake after sleep onset (WASO). However, based on multivariate analyses that included adult SES (model 2) and other covariates (model 3), men with more WASO did not have lower SES at age 7 as originally reported. Several univariate correlations between sleep measures and other variables change. Readers interested in copies of all corrected tables and figures should contact Matthewska@upmc.edu. The authors would like to apologize for any inconvenience caused.
