Downloaded from 2 1 2 3 ABSTRACT 4 5 6 Introduction: Chronic pain, defined as persistent or recurring pain lasting longer than three 7 8 months, is a common childhood problem and can profoundly impact children’s physical, 9 10 psychological, and social functioning. The last comprehensive systematic review estimating the 11 12 prevalence of chronic pain in children and adolescents was published in 2011. Since then, the 13 14 15 literature on pediatric chronic pain has grown substantially. This manuscript outlines a protocol 16 For peer review only 17 for an updated systematic review to provide updated estimates of the prevalence of various forms 18 19 of chronic pain in children and adolescence. The review will also examine the relationship 20 21 22 between sociodemographic and psychosocial factors related to chronic pain prevalence. 23 24 Methods and Analysis: This review will follow PRISMA guidelines. We will search EMBASE, 25 26 PubMed, CINAHL, and PsycINFO for observational studies published in English between 2009 27 28 29 and 2020 reporting population-based estimates of chronic non-disease-related pain prevalence in 30 31 children or adolescents (age 19 years). Two independent reviewers will screen the titles and 32 33 abstracts retrieved from the search based on predefined eligibility criteria. The full texts of http://bmjopen.bmj.com/ 34 35 36 relevant studies will then be assessed by two reviewers. Studies meeting inclusion criteria will be 37 38 categorized according to the type of pain investigated: headache only, abdominal pain only, back 39 40 pain only, musculoskeletal pain, combined pain, and other/general pain. Data will be extracted 41 on September 23, 2021 by guest. Protected copyright. 42 43 using customized forms and studies will be assessed for risk of bias using a 10-item tool 44 45 developed by Hoy et al. (2012). A narrative synthesis will summarize the prevalence estimates of 46 47 pediatric chronic pain and associated sociodemographic and psychosocial correlates. Meta- 48 49 analyses and meta-regressions will be performed if the data permit. 50 51 52 Ethics and dissemination: Ethical approval is not required. Findings will be disseminated 53 54 through publication in an academic journal, presentations at conferences, and in various media. 55 56 57 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 4 of 20 BMJ Open: first published as 10.1136/bmjopen-2020-043675 on 16 February 2021.
