Assessment of short stature in very low birthweight children.
The aims of this study of short very low birthweight (VLBW) children at or after 8 years of age were to determine: (i) if there were any unsuspected organic causes for their growth failure; and (ii) whether any children might be suitable for treatment with synthetic growth hormone. Thirty-seven of 195 (19%) VLBW children seen at 8 years had heights < 10th centile, and of these only 40% (10/25) of families offered an assessment were concerned enough to have the child fully evaluated. No child had an unsuspected organic cause of short stature. The children's parents were significantly shorter than expected for Caucasians (mean parental height s.d. score = -1.06 (s.d. 0.72), t = -5.9, P < 0.001). On average, the bone age of the short children was delayed by 14.9 months (s.d. 18.8 months) compared with chronological age (t = -3.4, P < 0.01). When compared with their parents, the children's mean height s.d. score for their bone age was not significantly different (mean height s.d. score for bone age = -0.83 (s.d. 1.3), t = 0.6, NS). Only three children qualified for treatment with synthetic growth hormone; all three had been small for gestational age at birth and had birthweights < 1000 g. In conclusion, in short VLBW children, only a minority of families and children are likely to be concerned enough about short stature to be fully assessed; an unsuspected organic cause for growth failure is unlikely, and only a few will qualify for synthetic growth hormone therapy.
