Salivary Biomarkers in Pediatric Metabolic Disease Research.
The increasing prevalence of childhood obesity and obesity-related metabolic disorders is now considered a global pandemic. The main goal of the pediatric obesity research community is to identify children who are at risk of becoming obese before their body mass index rises above age norms. To do so, we must identify biomarkers of metabolic health and immunometabolism that can be used for large-scale screening and diagnosis initiatives among at-risk children. Because blood sampling is often unacceptable to both parents and children when there is no direct benefit to the child, as in a community-based research study, there is a clear need for a low-risk, non-invasive sampling strategy. Salivary analysis is now well recognized as a likely candidate for this purpose. In this review, we discuss the physiologic role of saliva and its strengths and limitations as a fluid for biomarker discovery, obesity screening, metabolic disease diagnosis, and response monitoring after interventions. We also describe the current state of the salivary biomarker field as it pertains to metabolic research, with a special emphasis on studies conducted in children and adolescents. Finally, we look forward to technological developments, such as salivary "omics" and point of service diagnostic devices, which have the potential to accelerate the pace of research and discovery in this vitally important field.
