title: Are short normal children at a disadvantage? The Wessex growth study.
abstract: OBJECTIVE
  To examine whether short stature through childhood represents a disadvantage at around 12 years.
  
  
  METHODS
  Longitudinal non-intervention study of the physical and psychological development of children recruited from the community in 1986-7 after entry into primary school at age 5-6 years; this is the second psychometric assessment made in 1994-5 after entry into secondary school at age 11-13 years.
  
  
  METHODS
  Southampton and Winchester health districts.
  
  
  METHODS
  106 short normal children (< 3rd centile for height when recruited) and 119 controls of average stature (10th-90th centile).
  
  
  METHODS
  Psychometric measures of cognitive development, self concept development, behaviour, and locus of control.
  
  
  RESULTS
  The short children did not differ significantly from the control children on measures of self esteem (19.4 v 20.2), self perception (104.2 v 102.4), parents' perception (46.9 v 47.0), or behaviour (6.8 v 5.3). The short children achieved significantly lower scores on measures of intelligence quotient (IQ) (102.6 v 108.6; P < 0.005), reading attainment (44.3 v 47.9; P < 0.002), and basic number skills (40.2 v 43.5; P < 0.003) and displayed less internalisation of control (16.6 v 14.3; P < 0.001) and less satisfaction with their height (P < 0.0001). More short than control children, however, came from working class homes (P < 0.05). Social class was a better predictor than height of all measures except that of body satisfaction. Attainment scores were predicted by class and IQ together rather than by height. Height accounted for some of the variance in IQ and locus of control scores.
  
  
  CONCLUSIONS
  These results provide only limited support for the hypothesis that short children are disadvantaged, at least up until 11-13 years old. Social class seems to have more influence than height on children's psychological development.
