In addition, these children have impaired autonomic control, which may be exacerbated by sleep apnoea. The aim of this study was to compare autonomic control using heart rate variability and nocturnal dipping of heart rate in children with Prader\u2013Willi syndrome and typically developing children. We identified 50 children with Prader\u2013Willi syndrome and matched them for age, obstructive and central apnoea\u2010hypoponea index, body mass index and sex to 50 typically developing children. All children underwent overnight polysomnography. Time and frequency domain heart rate variability were analysed during N2, N3, REM and total sleep, and nocturnal dipping of heart rate from wake was calculated. Children with Prader\u2013Willi syndrome had reduced time domain heart rate variability in REM, reduced low frequency power in N2, higher heart rate in REM and total sleep (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05 for all) and reduced fall in heart rate from wake to REM (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05). When stratified into age groups, similar results were found in children \u2264\u20091 and &gt;\u20091\u2009\u2264\u20096\u2009years, with no differences between groups in children &gt;\u20096\u2009years of age. The significant reduction in LF power and nocturnal dipping indicates children with Prader\u2013Willi syndrome have delayed maturation of autonomic control, particularly below 6\u2009years of age. Investigating the impact of age on heart rate variability longitudinally and treatments such as growth hormone remains to be elucidated.\n                  <\/jats:p>","DOI":"10.1111\/jsr.70094","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T05:33:58Z","timestamp":1746768838000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Autonomic Control of Heart Rate During Sleep Is Depressed in Young Children With Prader\u2013Willi Syndrome"],"prefix":"10.1111","volume":"35","author":[{"given":"Okkes R.","family":"Patoglu","sequence":"first","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1158-493X","authenticated-orcid":false,"given":"Lisa M.","family":"Walter","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2351-6336","authenticated-orcid":false,"given":"Georgina","family":"Plunkett","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margot J.","family":"Davey","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"},{"name":"Melbourne Children's Sleep Centre Monash Children's Hospital  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gillian M.","family":"Nixon","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"},{"name":"Melbourne Children's Sleep Centre Monash Children's Hospital  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bradley A.","family":"Edwards","sequence":"additional","affiliation":[{"name":"Department of Physiology Biomedicine Discovery Institute and School of Psychological Sciences, Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3575-0461","authenticated-orcid":false,"given":"Rosemary S.
