Epidemiology of Pediatric Chronic Pain: An Overview of Systematic Reviews

Purpose of Review: Chronic non-cancer pain in children and adolescents represents a significant public health issue, affecting physical, psychological, and social well-being. Defined as pain persisting for over three months, this condition is influenced by developmental, socioeconomic, and cultural factors. However, its prevalence remains uncertain and debated. A comprehensive literature search was conducted across electronic databases, including Medline, Embase, CINAHL, PsycINFO, and the Cochrane Library. Eligible systematic reviews were critically appraised using the AMSTAR-2 tool to assess methodological quality. This overview synthesises evidence from existing systematic reviews to provide an updated understanding of the epidemiology and burden of paediatric non-cancer chronic pain. Recent Findings: Findings revealed substantial variability in the reported prevalence of specific pain types: headaches (4–83%), abdominal pain (4–53%), musculoskeletal pain (4–40%), and back/low-back pain (14–24%). Prevalence was generally lower in low- and middle-income countries, likely due to barriers in healthcare access. Methodological heterogeneity was observed across studies, and AMSTAR-2 assessment identified critical limitations in some systematic reviews, impacting the reliability of findings. Summary: This overview highlights the urgent need for standardised research methodologies to accurately monitor the prevalence of paediatric non-cancer chronic pain. Standardisation is essential for informing policies aimed at mitigating the long-term impact of chronic pain in children and adolescents. Addressing these issues, particularly in resource-limited settings, is crucial for improving health outcomes and reducing societal and economic burdens.
