Incidence is calculated as the incidence rate of new cases of obesity per 1000 person-years of follow-up and shown with 95% CIs using Poisson models. Obesity is defined as the first time a person has a BMI ≥30 kg/m2.
Overall incidence rates are adjusted for sex, race, and age. Sex-specific rates are adjusted for age and race. Age-specific rates are adjusted for race and sex. Race-specific rates are adjusted for sex and age. All incidence rates are shown as adjusted and weighted using survey weights, stratum, and cluster to reflect the US population in the period 2001–2017.
