Adult outcome of normal children who are short or underweight at age 7 years.
OBJECTIVE
To evaluate the adult growth outcome (at age 23) of children who are short or underweight at age 7 years in whom no identifiable pathological cause exists for their poor growth.


METHODS
Longitudinal follow up of a birth cohort.


METHODS
The national child development study (1958 birth cohort) of Great Britain.


METHODS
523 children with a height or a weight below the fifth centile at age 7. Of these, 70 (13.4%) were excluded because they had a longstanding illness that could account for their poor growth. The remaining 453 subjects, who were followed to age 23, provided the base group from which those with additional data, such as parental height, were obtained.


RESULTS
55/174 (31.6%) boys who were short at age 7 became short men; 60/211 (28.4%) girls who were short at age 7 became short women. Among boys who were underweight at age 7, 46/160 (28.7%) were still underweight at age 23, while 61/200 (30.5%) girls underweight at age 7 became underweight women. Having short parents did not increase the probability of being small as an adult. Children with delayed puberty were as likely to remain small as those in whom puberty was not delayed.


CONCLUSIONS
One in three normal children who was short or underweight at age 7 became a short or underweight adult. This informs the management of short children and may be valuable when prolonged growth hormone treatment for short stature is being considered.
