0945 SLEEP RHYTHMIC MOVEMENTS IN CHILDHOOD: ASSOCIATED BEHAVIORAL, PSYCHOLOGICAL AND MATERNAL CHARACTERISTICS
Notice bibliographique
Résumé
Sleep rhythmic movements (SRM) are stereotyped behaviors (mainly head-banging, body rocking and head-rolling) occurring during sleep or in the transition between wake and sleep. This parasomnia occurs primarily in childhood and its etiology remains unknown. It has been described as self-soothing mechanism, but evidences remain sparse. While associations between SRM and depression, anxiety, hyperactivity-inattention symptoms and maternal depression were documented, most studies used a retrospective design, which is subject to recall biases. The present study aims to (1)assess the prevalence of SRM in children from 12 to 60 months, and (2)document the association between SRM and psychological problems in children as well as maternal characteristics. Mother-child dyads (N=455, 245 boys) were part of the Maternal Adversity, Vulnerability and Neurodevelopment cohort. Presence or absence of SRM was assessed by annual report between ages 12 and 60 months: the mother was asked how frequently her child rocked himself/herself while falling asleep. Maternal sensitivity was assessed at 6 months with the Maternal Behaviour Q-Sort Revised version (MBQS-R). Behavioral problems were assessed at 48 and 60 months with the Children’s Behavioral Checklist (CBCL). Maternal depressive symptoms were assessed with the Center for Epidemiologic Studies Depression scale at each time point. Independent samples t-tests were used to assess differences between children with and without SRM. Results show that the highest prevalence of SRM is at 12 months(6.7%) and the lowest at 60 months(3.8%). Mothers of SRM children had lower scores of sensitivity and cooperation on the MBQS, as well as more depressive symptoms than mothers of non-SRM children. SRM children obtained higher mean total score on the CBCL and higher mean score for internalizing problems. These preliminary results show associations of SRM with lower maternal sensitivity and higher maternal depression, supporting the possible self-soothing component of SRM. Additionally, results show that SRM children present more internalizing problems. Mechanisms linking SRM, maternal well-being and children characteristics along with the evolution of these associations throughout development remain to be determined and will be further explored.
