Although efficient at a population-level, body mass index (BMI) has been criticized as a poor indicator of obesity and associated risk factors at the individual level. In 2009, Sharma & Kushner proposed the Edmonton Obesity Staging System (EOSS). The EOSS classifies obesity in stages according to risk factors and comorbidities alongside anthropometric measures.
Recently, Canadian leaders in the field of childhood obesity developed the EOSS for Pediatrics (EOSS-P), which captures the severity of obesity in children based on four domains of health – metabolic, mechanical, mental health, and social milieu. This tool may help health care providers to identify children with obesity at differential risk for chronic diseases and prioritize care accordingly.
