The Relationship Between Sleep-Disordered Breathing and Memory in Early Childhood

  • This dissertation consists of two related studies that examine children’s sleep in the first three years of life. The literature pointed to a need for more objective data concerning sleep in young children (Gokdemir & Ersu, 2016). However, it was not feasible to conduct lab polysomnography (PSG) on all participants. Therefore, the first study was developed to examine the reliability and validity of a home sleep recording device to diagnose sleep-disordered breathing (SDB) in 25 children with typical development. Results showed that the T3 home sleep device is a valid tool when compared to the in-hospital lab PSG. The T3 machine’s performance was comparable to PSG for several indexes but less effective for moderate apnea-hypopnea index (AHI) and oxygen desaturation index (ODI). For the second study, participants were recruited through the Canadian Healthy Infant Longitudinal Development (CHILD) Study in Edmonton. In this study I examined the relationships between sleep duration, SDB and several variables that influence the development of memory in 501 children at three years of age. CHILD cohort study participants were administered the Developmental NEuroPSYchological Assessment – Second Edition (NEPSY–II). Sleep was only associated with memory at age three in univariate analysis. The final model that best explained the primary outcome measure (NEPSY–II sentence repetition) included the following predictors: female, screen time, maternal fruit intake and neighbourhood crime index. These studies contribute to the pertinent literature in the area under study and emphasize the need for further research into the specificities of sleep disorders and the most important factors that affect early cognitive development.
