Bias and agreement were assessed using the Bland-Altman method and a novel application of criterion cut-point analysis. Objective measurements of wake after sleep onset (WASO) and sleep efficiency were evaluated.<\/p>\n\n\n\n<p id=\"st0035\"><strong>Results<\/strong><br>Sri Lankans have short sleep duration; averaging 6.4h (SD 1.5) self-reported and 6.0h (SD 0.9) actigraphically. Poor sleep quality was prevalent with an average WASO of 49 min., and sleep efficiency &lt;85%. Bias was observed, with self-report consistently over-reporting sleep on average by 27.6 min (95% CI: -0.68, -0.24) compared to objective measures, but wide individual variation in disagreement, ranging from over-reporting by 3.34h to under-reporting by 2.42h. A criterion cut-point method also failed to define agreed definitions of short and long sleep duration.<\/p>\n\n\n\n<p id=\"st0040\"><strong>Conclusions<\/strong><br>Sleep in Sri Lankan adults, whether measured subjectively or objectively, is of short duration and suboptimal objective quality by High Income Country consensus standards. Given the high cardiometabolic&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/nursing-and-health-professions\/morbidity\">morbidity<\/a>&nbsp;in Sri Lanka and poor measurement agreement observed, this warrants further investigation and supports the need for culturally appropriate, reliable, and valid assessment for analytic&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/medicine-and-dentistry\/cohort-effect\">epidemiology<\/a>&nbsp;in non-Western settings.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-uagb-container uagb-block-8b71c1c5\">\n<div class=\"wp-block-uagb-container uagb-block-68630121\">\n<div class=\"wp-block-uagb-container uagb-block-5e518491\">\n<p>Website:<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-uagb-container uagb-block-87ee0c4a\">\n<p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S2352721818301578?via%3Dihub\">Agreement between subjective and objective measures of sleep duration in a low-middle income country setting &#8211; ScienceDirect<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Describe sleep duration in adult Sri Lankans and determine the bias and agreement of self-report and actigraphic assessments.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_uag_custom_page_level_css":"","footnotes":""},"categories":[10,4],"tags":[],"class_list":["post-1072","post","type-post","status-publish","format-standard","hentry","category-papers","category-publication"],"translation":{"provider":"WPGlobus","version":"3.0.0","language":"si","enabled_languages":["en","si","ta"],"languages":{"en":{"title":true,"content":true,"excerpt":true},"si":{"title":false,"content":false,"excerpt":false},"ta":{"title":false,"content":false,"excerpt":false}}},"uagb_featured_image_src":{"full":false,"thumbnail":false,"medium":false,"medium_large":false,"large":false,"1536x1536":false,"2048x2048":false},"uagb_author_info":{"display_name":"admin","author_link":"https:\/\/sltr.ird.lk\/si\/author\/admin\/"},"uagb_comment_info":0,"uagb_excerpt":"Describe sleep duration in adult Sri Lankans and determine the bias and agreement of self-report and actigraphic assessments.","_links":{"self":[{"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/posts\/1072","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/comments?post=1072"}],"version-history":[{"count":2,"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/posts\/1072\/revisions"}],"predecessor-version":[{"id":1557,"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/posts\/1072\/revisions\/1557"}],"wp:attachment":[{"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/media?parent=1072"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/categories?post=1072"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sltr.ird.lk\/si\/wp-json\/wp\/v2\/tags?post=1072"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
