Data on 147 emerging adults (age\u2009=\u200919.4\u2009\u00b1\u20091.3\u2009years; body mass index\u2009=\u200926.4\u2009\u00b1\u20097.0\u2009kg\u2005m<jats:sup>\u22122<\/jats:sup>; 59% female; 65% White) from RIGHT Track Health were used. Actigraphy\u2010based sleep measures included sleep duration, sleep efficiency, sleep timing midpoint, day\u2010to\u2010day sleep duration and sleep timing midpoint variability. Combined sleep duration and sleep timing behaviours were also derived (early\u2010bed\/late\u2010rise, early\u2010bed\/early\u2010rise, late\u2010bed\/late\u2010rise, late\u2010bed\/early\u2010rise). Outcomes included body mass index and BodPod\u2010assessed fat mass index, fasting serum leptin, C\u2010reactive protein, and homeostatic model assessment\u2010insulin resistance. Sleep duration was 5.4\u2009h per night. We noted an inverse association between sleep duration and homeostatic model assessment\u2010insulin resistance. The early\u2010bed\/early\u2010rise group had greater body mass index, C\u2010reactive protein and homeostatic model assessment\u2010insulin resistance compared with the early\u2010bed\/late\u2010rise group (referent). Sex modified associations of sleep efficiency with C\u2010reactive protein; stratified results revealed positive association between sleep efficiency and C\u2010reactive protein in males, but not females. Race modified associations of sleep duration with body mass index and leptin, and of sleep duration variability with C\u2010reactive protein. Stratified analyses revealed inverse associations between sleep duration with body mass index and leptin in Black, multiracial\/other race individuals only. Positive association between sleep duration variability and C\u2010reactive protein was noted in White individuals only. Shorter sleep duration, particularly when combined with earlier sleep timing, is associated with greater adiposity and serum cardiometabolic outcomes. Additional studies are needed to assess individual\u2010 and contextual\u2010level factors that may contribute to sex and race differences in sleep health and cardiometabolic risk in emerging adults.<\/jats:p>","DOI":"10.1111\/jsr.14068","type":"journal-article","created":{"date-parts":[[2023,10,8]],"date-time":"2023-10-08T03:16:26Z","timestamp":1696734986000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Associations of actigraphy\u2010assessed sleep variables with adiposity and serum cardiometabolic outcomes in emerging adults"],"prefix":"10.1111","volume":"33","author":[{"given":"Jessica","family":"McNeil","sequence":"first","affiliation":[{"name":"Department of Kinesiology University of North Carolina at Greensboro  Greensboro North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathaniel T.","family":"Berry","sequence":"additional","affiliation":[{"name":"Department of Kinesiology University of North Carolina at Greensboro  Greensboro North Carolina USA"},{"name":"Under Armour, Inc., Innovation  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica M.","family":"Dollar","sequence":"additional","affiliation":[{"name":"Department of Kinesiology University of North Carolina at Greensboro  Greensboro North Carolina USA"},{"name":"Department of Psychology University of North Carolina at Greensboro  Greensboro North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lenka H.","family":"Shriver","sequence":"additional","affiliation":[{"name":"Department of Nutrition University of North Carolina at Greensboro  Greensboro North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan P.","family":"Keane","sequence":"additional","affiliation":[{"name":"Department of Psychology University of North Carolina at Greensboro  Greensboro North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilly","family":"Shanahan","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Zurich  Zurich Switzerland"},{"name":"Jacobs Center for Productive Youth Development University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurie","family":"Wideman","sequence":"additional","affiliation":[{"name":"Department of Kinesiology University of North Carolina at Greensboro  Greensboro North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,10,6]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1530\/joe-21-0155"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1037\/0003-066X.55.5.469"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.orcp.2020.03.004"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.4278\/ajhp.121012-QUAN-500"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/zsx156"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajhb.23056"},{"key":"e_1_2_10_8_1","unstructured":"Casper\u2010Gallop.
