BMI, Body mass index; CI, confidence interval.

a

Model 1 – adjusted for age, age2 and age3; model 2 – additionally adjusted for BMI at age 11 years; model 3 – additionally adjusted for BMI at age 11 years and childhood and adult social class.

b

Profile 1=absence of symptoms; profile 2=adolescent-onset repeated symptoms; profile 3=adolescent-onset symptoms with good adult outcome; profile 4=adult-onset repeated symptoms.

c

Coefficients represent the mean difference in BMI at age 15 years between each profile and profile 1.

d

Coefficients represent the mean difference in BMI change per year (from 15 to 53 years) between each profile and profile 1.
