Age-specific incidence of obesity by sex, race, baseline weight status, and period. Shown is the age-specific incidence rate of obesity as cases per 1000 person-years (PYs) with 95% CIs, according to sex (A) (n: 6621 males; 7267 males); race (B) (n: 9118 Whites; 3917 Blacks; 853 Other Races); weight status at first anthropometric record (C) (n: 7379 with normal weight; 6509 with overweight); and by period (D) (n: 8959 in 2001–2005; 9217 in 2005–2009; 9437 in 2009–2013; 9136 in 2013–2017). Incidence rates were calculated using Poisson models. Normal weight is defined as a BMI <25 kg/m2, overweight is defined as a BMI ≥25 kg/m2 and <30 kg/m2, and obesity is defined as the first time a person has a BMI ≥30 kg/m2.
