0423 TYPE-SPECIFIC EFFECTS OF CHILDHOOD MALTREATMENT ON ADULT SLEEP PROBLEMS

Abstract

Introduction: Childhood maltreatment (CM) is a highly important but often overlooked predictor of adult sleep problems. Given approximately 40% of individuals experience CM, characterisation of the relationship between CM and adult sleep problems could be particularly useful for identification and early intervention of individuals at risk of developing insomnia. Method(s): 1219 individuals from the Netherlands Sleep Registry (age 19-89years, 915 females, 633 insomnia) completed the Insomnia Severity Index (ISI), Childhood Trauma Questionnaire and Hospital Anxiety and Depression Scale. First, we quantified the risk of developing insomnia following CM. Then using a partial least squares analysis, we examined the CM-subtype specific effects on adult insomnia symptoms (ISI components), as well as the moderating effects of age, gender, depressive symptoms and anxiety symptoms. Result(s): CM was related to a 1.54 fold increase in the risk of developing insomnia. Childhood physical neglect was associated with worse sleep patterns (ISI-4, beta=0.19, 0.008
