Cochran Q and R\u00fccker Q heterogeneity tests are conducted using IVW and MR-Egger methods, with the Egger-intercept method for pleiotropy testing, leave-one-out sensitivity analysis, and calculation of F-statistics to assess the presence of weak instrument bias.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study reveals that genetically predicted insomnia significantly increases the risk of unspecified pain, chest pain, gum pain, upper abdominal pain, and lower abdominal pain occurrence. Daytime napping is associated with a moderate reduction in the likelihood of joint pain but may concomitantly elevate the risk of chest pain, upper abdominal pain, and generalized abdominal pain. Neither sleep chronotype nor sleep duration demonstrated a definitive causal relationship with pain perception.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study elucidates the causal relationships between four sleep characteristics and pain across 10 different body regions. Overall, the contribution of insomnia and sleep deficiency to pain in multiple body regions is more pronounced. Conversely, the association between adequate sleep and the likelihood of somatic pain is relatively lower and less significant.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnins.2024.1428951","type":"journal-article","created":{"date-parts":[[2024,8,15]],"date-time":"2024-08-15T20:25:37Z","timestamp":1723753537000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["The causal relationship between sleep characteristics and multi-site pain perception: a two-sample Mendelian randomization study"],"prefix":"10.3389","volume":"18","author":[{"given":"Yulai","family":"Yin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyu","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,8,13]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"363","DOI":"10.1016\/S0304-3959(96)03226-5","article-title":"Sequential daily relations of sleep, pain intensity, and attention to pain among women with fibromyalgia","volume":"68","author":"Affleck","year":"1996","journal-title":"Pain"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"1147","DOI":"10.1007\/s11325-020-02188-w","article-title":"Sleep quality, sleep latency, and sleep duration: a national comparative study of university students in Jordan","volume":"25","author":"Albqoor","year":"2021","journal-title":"Sleep Breath."},{"key":"ref3","doi-asserted-by":"publisher","first-page":"703","DOI":"10.1016\/j.nurt.2009.07.009","article-title":"Preclinical and early clinical investigations related to monoaminergic pain modulation","volume":"6","author":"Bannister","year":"2009","journal-title":"Neurotherapeutics"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"132","DOI":"10.1016\/j.sleep.2022.05.006","article-title":"Does sleep quality modify the relationship between common mental disorders and chronic low back pain in adult women?","volume":"96","author":"Barazzetti","year":"2022","journal-title":"Sleep Med."},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1101\/cshperspect.a041302","article-title":"Mendelian Randomization","volume":"12","author":"Birney","year":"2022","journal-title":"Cold Spring Harb.
