Previous studies show skin-to-skin contact (SSC) improves stress resiliency; however, linkages between SSC and HF-HRV on outcomes have not been assessed. We aimed to test the hypothesis that increased SSC frequency would enhance HF-HRV, reduce neonatal morbidity, and improve developmental outcomes.<\/jats:p>\n                  <jats:p>Study Design\u2003Weekly electrocardiograms and clinical data were obtained from 101 preterm neonates. SSC frequency was determined from the electronic medical record.<\/jats:p>\n                  <jats:p>Results\u2003At postnatal week 1, frequency of SSC and HF-HRV were positively correlated (p =.02); further, multiple stepwise regressions showed higher HF-HRV and SSC predicted reduced days on ventilation and oxygen, and shorter hospital stay (p\u2009&lt;\u20090.001). Higher HF-HRV predicted lower postmenstrual age (PMA) at discharge (p\u2009&lt;\u20090.01).<\/jats:p>\n                  <jats:p>Conclusion\u2003Higher SSC frequency was associated with increased HF-HRV during the first postnatal week. SSC and HF-HRV uniquely predicted diminished neonatal morbidity throughout hospitalization. Additionally, HF-HRV uniquely predicted earlier PMA at discharge. Augmenting SSC early in life enhances stress resiliency and improves health outcomes.<\/jats:p>","DOI":"10.1055\/s-0038-1669946","type":"journal-article","created":{"date-parts":[[2018,9,7]],"date-time":"2018-09-07T18:47:16Z","timestamp":1536346036000},"page":"505-510","source":"Crossref","is-referenced-by-count":27,"title":["Increased Frequency of Skin-to-Skin Contact Is Associated with Enhanced Vagal Tone and Improved Health Outcomes in Preterm Neonates"],"prefix":"10.1055","volume":"36","author":[{"given":"Megan","family":"Marvin","sequence":"additional","affiliation":[{"name":"Division of Neonatal-Perinatal Medicine, Department of Pediatrics, The Pennsylvania State University, College of Medicine, Hershey, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiyuki","family":"Gardner","sequence":"additional","affiliation":[{"name":"Division of Neonatal-Perinatal Medicine, Department of Pediatrics, The Pennsylvania State University, College of Medicine, Hershey, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristin","family":"Sarsfield","sequence":"additional","affiliation":[{"name":"Division of Neonatal-Perinatal Medicine, Department of Pediatrics, The Pennsylvania State University, College of Medicine, Hershey, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Travagli","sequence":"additional","affiliation":[{"name":"Department of Neural and Behavioral Sciences, The Pennsylvania State University, College of Medicine, Hershey, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kim","family":"Doheny","sequence":"additional","affiliation":[{"name":"Division of Neonatal-Perinatal Medicine, Department of Pediatrics, The Pennsylvania State University, College of Medicine, Hershey, Pennsylvania"},{"name":"Department of Neural and Behavioral Sciences, The Pennsylvania State University, College of Medicine, Hershey, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2018,9,7]]},"container-title":["American Journal of Perinatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1669946.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T18:44:39Z","timestamp":1554230679000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1669946"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,7]]},"references-count":0,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2019,4,2]]},"published-print":{"date-parts":[[2019,4]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1669946","relation":{},"ISSN":["0735-1631","1098-8785"],"issn-type":[{"value":"0735-1631","type":"print"},{"value":"1098-8785","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,9,7]]}}}
