Hypothesis: A sleep study of 10 h will provide equivalent information compared to a 20-h study to detect significant cardio-respiratory abnormalities in this population. Methods: Single-center retrospective study of 50 infants with 20-h sleep study. Studies were evaluated for periodic breathing, obstructive, central, mixed apnea, desaturations, and bradycardia. Each study was partitioned into two 10-h epochs, compared to one another and the 20-h study. Results: Differences were detected at the level of individual sleep studies when each epoch was compared to each other and a total 20-h study. 10-h study missed 17\u201331% of breathing abnormalities detected over 20 h adjusted for study time. Group analysis showed no statistical difference in the number and duration of events between epochs. Conclusions: A 20-h sleep study improves the detection of breathing abnormalities missed with a 10-h study.<\/jats:p>","DOI":"10.3390\/children12010074","type":"journal-article","created":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T09:30:45Z","timestamp":1736328645000},"page":"74","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Study-Duration and Time of Day on Multichannel Sleep Study Findings in Former Preterm Infants"],"prefix":"10.3390","volume":"12","author":[{"given":"Allison","family":"Sadowski","sequence":"first","affiliation":[{"name":"Connecticut Children\u2019s Medical Center\u2014Hartford, 282 Washington Street, Hartford, CT 06106, USA"},{"name":"Division of Neonatology, Department of Pediatrics, University of Connecticut School of Medicine, Hartford, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1809-5760","authenticated-orcid":false,"given":"Naveed","family":"Hussain","sequence":"additional","affiliation":[{"name":"Connecticut Children\u2019s Medical Center\u2014Hartford, 282 Washington Street, Hartford, CT 06106, USA"},{"name":"Division of Neonatology, Department of Pediatrics, University of Connecticut School of Medicine, Hartford, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonard I.","family":"Eisenfeld","sequence":"additional","affiliation":[{"name":"Connecticut Children\u2019s Medical Center\u2014Hartford, 282 Washington Street, Hartford, CT 06106, USA"},{"name":"Division of Neonatology, Department of Pediatrics, University of Connecticut School of Medicine, Hartford, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariann","family":"Pappagallo","sequence":"additional","affiliation":[{"name":"Connecticut Children\u2019s Medical Center\u2014Hartford, 282 Washington Street, Hartford, CT 06106, USA"},{"name":"Division of Neonatology, Department of Pediatrics, University of Connecticut School of Medicine, Hartford, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet","family":"Schwenn","sequence":"additional","affiliation":[{"name":"Department of Nursing, UCONN Health, Farmington, CT 06030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ted S.","family":"Rosenkrantz","sequence":"additional","affiliation":[{"name":"Connecticut Children\u2019s Medical Center\u2014Hartford, 282 Washington Street, Hartford, CT 06106, USA"},{"name":"Division of Neonatology, Department of Pediatrics, University of Connecticut School of Medicine, Hartford, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"E388","DOI":"10.1111\/jpc.12247","article-title":"Current definitions for neonatal apnoea: Are they evidence based?","volume":"49","author":"Elder","year":"2013","journal-title":"J.
