FSHD scored worse than CTRL on the Insomnia Severity Index (P&lt;0.05). 25\u201363% and 50\u201381% of adults with MD reported poor sleep quality using the Insomnia Severity Index and PSQI, respectively. Accelerometery identified no difference in sleep quality between groups. Associations were identified between sleep measures (PSQI global and insomnia severity) with mental or physical QoL in LGMD, BMD and FSHD. Multiple regression identified associations between sleep impairment and fatigue severity (all MDs), body composition (BMD &amp; LGMD), upper and lower limb function (LGMD, FSHD) and age (FSHD).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>25\u201381% of men with MD, depending on classification, experience sleep impairment, using self-report sleep measures. Whilst BMD and FSHD showed worse sleep outcomes than CTRL, no group difference was observed between LGMD and CTRL, however all groups showed associations with sleep impairment and higher levels of fatigue. These findings, and associations with measures of health and wellbeing, highlight an area for further research which could impact QoL in adults with MD.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0274970","type":"journal-article","created":{"date-parts":[[2022,9,22]],"date-time":"2022-09-22T17:58:25Z","timestamp":1663869505000},"page":"e0274970","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":11,"title":["Objective and subjective measures of sleep in men with Muscular Dystrophy"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5261-2637","authenticated-orcid":true,"given":"Christopher I.","family":"Morse","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1466-3265","authenticated-orcid":true,"given":"Gladys","family":"Onambele-Pearson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryn","family":"Edwards","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sze Choong","family":"Wong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew F.","family":"Jacques","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,9,22]]},"reference":[{"issue":"2","key":"pone.0274970.ref001","doi-asserted-by":"crossref","first-page":"273","DOI":"10.1016\/0021-9681(60)90105-3","article-title":"Maintenance of ambulation in childhood muscular dystrophy","volume":"12","author":"PJ Vignos","year":"1960","journal-title":"Journal of chronic diseases"},{"issue":"11","key":"pone.0274970.ref002","doi-asserted-by":"crossref","first-page":"996","DOI":"10.1136\/jnnp.46.11.996","article-title":"Motor unit size in muscular dystrophy, a macro EMG and scanning EMG study","volume":"46","author":"P Hilton-Brown","year":"1983","journal-title":"Journal of Neurology, Neurosurgery & Psychiatry"},{"issue":"4","key":"pone.0274970.ref003","doi-asserted-by":"crossref","first-page":"546","DOI":"10.1302\/0301-620X.66B4.6746690","article-title":"The management of equinus deformity in Duchenne muscular dystrophy","volume":"66","author":"EA Williams","year":"1984","journal-title":"The Journal of bone and joint surgery British volume"},{"issue":"1","key":"pone.0274970.ref004","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1007\/BF00314217","article-title":"Muscle hypertrophy in Duchenne muscular dystrophy","volume":"236","author":"D Cros","year":"1989","journal-title":"Journal of neurology"},{"issue":"1","key":"pone.0274970.ref005","doi-asserted-by":"crossref","DOI":"10.1186\/s12955-019-1177-y","article-title":"Quality of life in adults with muscular dystrophy","volume":"17","author":"MF Jacques","year":"2019","journal-title":"Health and quality of life outcomes"},{"issue":"3","key":"pone.0274970.ref006","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1002\/mus.25991","article-title":"Chronic pain has a strong impact on quality of life in facioscapulohumeral muscular dystrophy","volume":"57","author":"G Mor\u00eds","year":"2017","journal-title":"Muscle & Nerve"},{"issue":"3","key":"pone.0274970.ref007","doi-asserted-by":"crossref","first-page":"391","DOI":"10.1016\/j.nut.2015.09.004","article-title":"Impact of corticotherapy, nutrition, and sleep disorder on quality of life of patients with Duchenne muscular dystrophy.","volume":"32","author":"G Jeronimo","year":"2016","journal-title":"Nutrition"},{"issue":"7","key":"pone.0274970.ref008","doi-asserted-by":"crossref","first-page":"879","DOI":"10.1177\/0883073815627879","article-title":"Factors associated with Health-Related Quality of Life in children with Duchenne muscular dystrophy","volume":"31","author":"Y Wei","year":"2016","journal-title":"Journal of child neurology"},{"issue":"5","key":"pone.0274970.ref009","first-page":"508","article-title":"Health\u2010related quality of life in patients with Duchenne muscular dystrophy: a multinational, cross\u2010sectional study.
