  1. aScores are as follows: Baseline is parent class (I=1, II=2, IIInm=3, IIIm=4, IV=5, V=6); 2nd measurement is own educational and occupational status (full-time education=1, non-manual occupation=2, manual occupation=3, not in education or employment=4); 3rd-5th measurements are own current class (I=1, II=2, IIInm=3, IIIm=4, IV=5, V=6, not in employment=7).
  2. bValues for the second visit count only those not in education or employment.
  3. cAt baseline poor mental health is indicated by a GHQ-12 score ≥2, at all other visits by HADS sub-scale scores ≥8.
