^aEstimates from longitudinal generalized estimating equations excluding biologically implausible self-reported values.

^bWeight classification according to Centers for Disease Control and Prevention age- and sex-specific BMI percentile cut-offs until age 20 years (underweight= <5; normal weight= ≥5, <85; overweight= ≥85, <95; obese= ≥95). From age ≥20 years, underweight=BMI <18.5; normal weight=BMI ≥18.5, <25; overweight=BMI ≥25, <30; obese=BMI ≥30.
