BMI measured: derived from measured height and weight collected in MoMo
BMI reported: derived from self-reported height and weight collected in the telephone interview from KiGGS Wave 1 participants which also participated in MoMo
I1 … I5: i-th category for BMI and j-th category for BMIreported (i.e., 1 = extremely underweight, 2 = underweight, 3 = normal weight, 4 = overweight, 5 = obese)
I6: Missing value for self-reported height and/or weight
Q jk Prevalence rates of weight status categories j derived from self-reported height and weight according to body perception = k in KiGGS Wave 1
∝ijk = P (BMI measured ∈ I i | BMI reported ∈ I j , BP = k)
