Prevalence of doctor-diagnosed arthritis in U.S. adults in 2019-2021, by weight

Doctor-diagnosed arthritis was defined as an affirmative response to the question “Have you ever been told by a doctor or other health professional that you have some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia?"
Age adjusted to the 2000 U.S. projected adult population, using three age groups: 18–44, 45–64, and ≥65 years.
Self-reported height and weight were used to calculate BMI [weight (kg)/(height [m])2].
