We established a prospective cohort of women to determine incident sleep issues and their adverse health outcomes during pregnancy and beyond, and present here the baseline cohort profile. Antenatal women in gestational weeks 8\u201312 were recruited (n = 535) and followed-up in each trimester and at 5\u20136 weeks postpartum (no attrition). Sleep symptoms and disorders were measured using STOP-Bang and Berlin questionnaires and Pittsburgh Sleep Quality Index. Incident health outcomes were extracted from clinical records. At the time of recruitment, habitual snoring was present in 13.8% of participants; \u201cexcessive sleepiness during the day\u201d (EDS) in 42.8%; short (&lt;7 h) sleep duration in 46.4%; \u201chaving trouble sleeping\u201d in 15.3%; and \u201cpoor subjective sleep quality\u201d in 8.6%. Habitual snoring was strongly associated with irregular menstrual periods for one year preceding pregnancy (p = 0.014) and higher BMI (p &lt; 0.001). Higher age was associated with less \u201ctrouble sleeping\u201d (OR 0.9, p = 0.033) and longer sleep duration was associated with better \u201csubjective sleep quality\u201d (OR 0.8, p = 0.005). Sleep issues were highly prevalent at baseline and associated with age, irregular menstruation, and obesity. This cohort will provide a robust platform to investigate incident sleep disorders during pregnancy and their effects on adverse pregnancy outcomes and long-term health of women and their offspring.<\/jats:p>","DOI":"10.3390\/ijerph20032070","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T04:19:22Z","timestamp":1674447562000},"page":"2070","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Longitudinal Sleep Study in Pregnancy: Cohort Profile and Prevalence and Risk Factors for Sleep Symptoms in the First Trimester"],"prefix":"10.3390","volume":"20","author":[{"given":"Chamara V.","family":"Senaratna","sequence":"first","affiliation":[{"name":"Allergy and Lung Health Unit, Melbourne School of Population and Global Health, The University of Melbourne, Melbourne, VIC 3010, Australia"},{"name":"Non-Communicable Diseases Research Centre, University of Sri Jayewardenepura, Nugegoda 10250, Sri Lanka"},{"name":"Department of Community Medicine, University of Sri Jayewardenepura, Nugegoda 10250, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nirmala","family":"Priyadarshanie","sequence":"additional","affiliation":[{"name":"Department of Nursing & Midwifery, Faculty of Allied Health Sciences, General Sir John Kotelawala Defence University, Dehiwala-Mount Lavinia 10390, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6586-1034","authenticated-orcid":false,"given":"Sharaine","family":"Fernando","sequence":"additional","affiliation":[{"name":"Department of Physiology, University of Sri Jayewardenepura, Nugegoda 10250, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3368-7959","authenticated-orcid":false,"given":"Sampatha","family":"Goonewardena","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, University of Sri Jayewardenepura, Nugegoda 10250, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1266-9014","authenticated-orcid":false,"given":"Pramodya","family":"Piyumanthi","sequence":"additional","affiliation":[{"name":"Non-Communicable Diseases Research Centre, University of Sri Jayewardenepura, Nugegoda 10250, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Perret","sequence":"additional","affiliation":[{"name":"Allergy and Lung Health Unit, Melbourne School of Population and Global Health, The University of Melbourne, Melbourne, VIC 3010, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Lodge","sequence":"additional","affiliation":[{"name":"Allergy and Lung Health Unit, Melbourne School of Population and Global Health, The University of Melbourne, Melbourne, VIC 3010, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1744-2839","authenticated-orcid":false,"given":"Garun S.","family":"Hamilton","sequence":"additional","affiliation":[{"name":"Monash Lung, Sleep, Allergy and Immunology, Monash Health, Melbourne, VIC 3168, Australia"},{"name":"School of Clinical Sciences, Monash University, Melbourne, VIC 3800, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6063-1937","authenticated-orcid":false,"given":"Shyamali C.","family":"Dharmage","sequence":"additional","affiliation":[{"name":"Allergy and Lung Health Unit, Melbourne School of Population and Global Health, The University of Melbourne, Melbourne, VIC 3010, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1186\/1742-4755-11-61","article-title":"Maternal and perinatal health research priorities beyond 2015: An international survey and prioritization exercise","volume":"11","author":"Souza","year":"2014","journal-title":"Reprod.
