HealthDay News — Many patients with obesity, as classified according to body mass index (BMI), have not received a formal diagnosis using International Classification of Diseases, Ninth Revision (ICD-9) documentation, according to a study presented at the annual meeting of The Obesity Society (ObesityWeek), held from October 31 to November 4 in New Orleans.
Bartolome Burguera, MD, PhD, from the Cleveland Clinic, and colleagues used electronic health record data to create a cross-sectional summary of patients. Data were included for 324,199 active patients, stratified according to BMI category.
The researchers found that 37.4% of patients were overweight (BMI ≥25 and <29.9 kg/m²), and 23.2, 10.5, and 7.8%, respectively, had obesity class 1, 2, and 3 (BMI: 30 to 34.9, 35 to 39.9, and ≥40 kg/m², respectively). The prevalences of type 2 diabetes, hypertension, and cardiovascular disease were increased within higher versus lower BMI categories (P<0.0001). Only 48% of patients with a BMI >30 kg/m² had a documentation of an ICD-9 code for obesity. Only 75% of patients with a BMI >40 kg/m² had an ICD-9 code for obesity.
“The disease of obesity is very prevalent yet too often underdiagnosed, which could be an important barrier to getting initial care,” Burguera said in a statement. “By providing a formal diagnosis, we may be able to help people get the treatment they need to lose weight and get healthy.”
The study was funded by Novo Nordisk.
