Common questions
How many prescribers treat obesity & weight management?
12,845 active Type 1 NPIs in the treating specialties (obesity medicine and endocrinology), 7,744 of them matched to a home address for CTV, streaming and display. Another 705,983 referring prescribers are counted separately. Counts come from the CMS NPPES registry, September 2026.
How was the obesity & weight management patient audience validated?
In Semcasting's Audience Quality Test, the obesity & weight management audience held 1.63x more high-fit households than the U.S. population (score 68 or higher) and 1.47x more qualified households (score 64 or higher). During a campaign the same comparison runs every week on the households actually reached.
Does the obesity & weight management audience use diagnosis, claims or prescription data?
No. Patient audiences are built from peer-reviewed, population-level public health reporting and population surveys, scored against Semcasting's national adult file. No diagnosis records, claims, prescriptions or PHI are used, and the score says nothing about any one person's health.

How the audience is built
Patient counts for obesity & weight management come from physician-reported registries, diagnostic population surveys, and federal (CDC, CMS, NIH) and disease-association reporting, listed above. Each of 251.7M U.S. adult records is scored 0 to 100 for fit to those published patient profiles by age, gender and income, weighted by geographic prevalence (CDC PLACES: Obesity (OBESITY)). Qualified means a score of 64 or higher. High-fit means 68 or higher.
How quality is confirmed
Audience quality has historically been confirmed through holdout sampling: a delivered audience is compared with the full national panel at the same fixed score cutoffs, and the difference is reported as lift. During a campaign, the same comparison runs every week on the households actually reached.
What it is not
Qualified audiences are not built from modeled claims data extrapolated from a few locations. They come from peer-reviewed, population-level public health reporting on patient profiles and population surveys. No diagnosis records, claims, prescriptions or PHI are used, and the score says nothing about any one person's health.
