Although research has extensively explored the association between sleep and chronic conditions, few studies have investigated the association between multiple co-existing chronic conditions on sleep duration. This study examines the association between sleep duration and the prevalence of chronic conditions in the Canadian adults from four provinces and two territories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methodology<\/jats:title>\n                    <jats:p>Canadian Community Health Survey (CCHS) 2017\u20132018, a population-based cross-sectional survey, was used for this study. The outcome variable, sleep duration, was assessed based on the question \u201cNumber of hours per night usually spent sleeping?\u201d and categorized into three groups: \u201cIn between 7 and 9 h,\u201d \u201cShort sleep duration (&amp;lt; 7 h),\u201d and \u201cLong sleep duration (&amp;gt;9 h).\u201d The primary predictor, chronic conditions, was aggregated with a response of \u201cyes\u201d and subsequently categorized into no chronic condition, one chronic condition, two chronic conditions, and three or more chronic conditions, based on 12 recorded chronic conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Approximately 41% of respondents reported short sleep duration, while 7.73% reported long sleep duration. Compared with respondents with fewer or no chronic conditions, those with three or more co-existing chronic conditions had significantly higher odds of reporting abnormal sleep duration. Specifically, respondents with three or more chronic conditions were 1.70 times more likely to report short sleep duration (95% CI: 1.52\u20131.91) and 2.58 times more likely to report long sleep duration (95% CI: 1.96\u20133.41). The odds of both short and long sleep duration increased progressively with a higher number of chronic conditions, indicating a graded association between chronic conditions and abnormal sleep duration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The study underscores a strong association between the number of chronic conditions and sleep duration among adults, highlighting that multimorbidity is associated with abnormal sleep patterns.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/frsle.2026.1714511","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T04:42:31Z","timestamp":1788928951000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Association between sleep duration and co-existing chronic conditions in adults: insights from the 2017\u20132018 Canadian Community Health Survey"],"prefix":"10.3389","volume":"5","author":[{"given":"Shirmin Bintay","family":"Kader","sequence":"first","affiliation":[{"name":"Department of Community Health and Epidemiology, University of Saskatchewan","place":["Saskatoon, SK, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jubayer","family":"Mumin","sequence":"additional","affiliation":[{"name":"Department of Global Public Health, Karolinska Institute","place":["Stockholm, Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nahin","family":"Shakurun","sequence":"additional","affiliation":[{"name":"Department of Community Health and Epidemiology, University of Saskatchewan","place":["Saskatoon, SK, Canada"]},{"name":"Directorate General of Health Services (DGHS), Ministry of Health and Family Welfare","place":["Dhaka, Bangladesh"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumsun Nahar","family":"Zinia","sequence":"additional","affiliation":[{"name":"Department of Community Health and Epidemiology, University of Saskatchewan","place":["Saskatoon, SK, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zoe","family":"Schipper","sequence":"additional","affiliation":[{"name":"Department of Community Health and Epidemiology, University of Saskatchewan","place":["Saskatoon, SK, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nusrat Sharmin","family":"Ritu","sequence":"additional","affiliation":[{"name":"NISPOM RT-PCR Lab, National Institute of Preventive and Social Medicine (NIPSOM)","place":["Dhaka, Bangladesh"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheikh Ahmedul","family":"Haque","sequence":"additional","affiliation":[{"name":"Research Division, Platform Doctors Foundation","place":["Dhaka, Bangladesh"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Md.
