Background: Pediatric obesity is a growing concern in the United States and has been linked to negative psychological health outcomes such as depression, anxiety, and decreased quality of life. Obesity is a complex disease that is influenced by several environmental and social factors that are often out of an individuals' control. The etiology of pain in youth with obesity is not well understood. There are likely many factors that overlap and influence each other, including those related to functional limitation, sleep quality, and psychological health that exacerbate symptoms as a whole. Methods: This study examined the relationship between obesity level (BMI z-score) and youth self reports of: pain, functional limitation, sleep quality, depressive symptoms, and health-related quality of life (HRQoL). Ninety-eight patients completed validated surveys of pain, pain burden, functional disability, sleep, depression, and HRQoL as standard of care during their initial visit in Weight Management Program at Connecticut Children's Medical Center. Indirect effects of pain measures (pain scores and pain burden) on HRQoL through functional limitation, sleep quality, and depressive symptoms, respectively, were tested using bootstrapping according to Hayes.34 Results: Significant indirect effects and full mediation for both models were found. Conclusions: This study uniquely contributes to existing research through the discovery of the serial mediating effects of these variables in the relationship between youth pain and HRQoL. Although these variables have been studied independently as influential in this relationship in past research, this is the first study to examine how they interact through serial mediation models.
