The present study investigated the presence of sleep disturbances in a group of children and adolescents with DS and their cognitive and behavioral correlates. Seventy-one children and adolescents with DS underwent a neuropsychological evaluation, whereas parents completed questionnaires for the screening of the child\u2019s sleep, emotional and behavioral problems. We found no association between sleep disturbances and sex, nonverbal IQ, nor adaptive abilities. However, we found that age was positively associated with disorders in initiating and maintaining sleep (DIMS) and disorders of excessive somnolence (DOES), while body mass index was related with DOES. We also detected a relationship between visual-motor integrations and DIMS, as well as multiple associations between sleep disturbances and psychopathological and behavioral problems, mainly externalizing symptoms. The present study provided a detailed characterization of sleep problems in relation to several features of youths with DS. The proper identification of sleep disturbances profile in the DS population could support the process of clinical evaluation, in particular for psychopathological aspects.<\/jats:p>","DOI":"10.3390\/ijerph18095001","type":"journal-article","created":{"date-parts":[[2021,5,9]],"date-time":"2021-05-09T21:32:46Z","timestamp":1620595966000},"page":"5001","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Characterization of Sleep Disturbances in Children and Adolescents with Down Syndrome and Their Relation with Cognitive and Behavioral Features"],"prefix":"10.3390","volume":"18","author":[{"given":"Elisa","family":"Fuc\u00e0","sequence":"first","affiliation":[{"name":"Child and Adolescent Neuropsychiatry Unit, Department of Neuroscience, Bambino Ges\u00f9 Children\u2019s Hospital, IRCCS, 00165 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0877-9691","authenticated-orcid":false,"given":"Floriana","family":"Costanzo","sequence":"additional","affiliation":[{"name":"Child and Adolescent Neuropsychiatry Unit, Department of Neuroscience, Bambino Ges\u00f9 Children\u2019s Hospital, IRCCS, 00165 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Celestini","sequence":"additional","affiliation":[{"name":"Child and Adolescent Neuropsychiatry Unit, Department of Neuroscience, Bambino Ges\u00f9 Children\u2019s Hospital, IRCCS, 00165 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Mandarino","sequence":"additional","affiliation":[{"name":"Child and Adolescent Neuropsychiatry Unit, Department of Neuroscience, Bambino Ges\u00f9 Children\u2019s Hospital, IRCCS, 00165 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Vicari","sequence":"additional","affiliation":[{"name":"Child and Adolescent Neuropsychiatry Unit, Department of Neuroscience, Bambino Ges\u00f9 Children\u2019s Hospital, IRCCS, 00165 Rome, Italy"},{"name":"Department of Life Science and Public Health, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"747","DOI":"10.1002\/bdra.20294","article-title":"National estimates and race\/ethnic-specific variation of selected birth defects in the United States, 1999\u20132001","volume":"76","author":"Canfield","year":"2006","journal-title":"Birth Defects Res.
