Objective: The objective of this study was to describe the prevalence of obesity, obesity-related conditions (ORCs), and antiobesity medication (AOM) eligibility and prescribing practice among eligible patients in a large health care system.
Methods: In this cross-sectional analysis of the multicenter Mass General Brigham health care system (Boston, Massachusetts) spanning 2018 to 2022, adults eligible for AOMs (BMI ≥ 30 kg/m2 or BMI 27-29.9 kg/m2 with ≥1 ORC) were identified. Among those AOM-eligible, the prevalence of prescriptions for AOMs approved for long-term weight management was evaluated.
Results: Of 2,469,474 adults (mean [SD], age 53 [19] years; 57% female; BMI 28.1 [6.3] kg/m2), a total of 1,110,251 (45.0%) were eligible for AOMs. Of these, 69.4% (31.2% of overall cohort) had BMI ≥ 30 kg/m2. AOM prescription was observed in 15,214 (1.4%) of all eligible patients, with female sex, younger age, higher BMI, commercial insurance, and greater ORC burden associated with higher prevalence of AOM prescriptions. Musculoskeletal disorders (54%) were the most common ORCs, with ≥2 ORCs observed in 62% of patients. Liraglutide 3.0 mg and semaglutide 2.4 mg were the most frequently prescribed AOMs (58% and 34% of all AOMs, respectively).
Conclusions: Although nearly one-half of all patients in a large health care system were AOM-eligible by guidelines and regulatory labeling, only 1% of those who were eligible were prescribed AOMs.
