Objective: This analysis of previously published reports was performed to examine the effects of gonadotropin-releasing hormone (GnRH) agonist treatment on adult height and the factors associated with adult height outcomes. Context: GnRH agonists are first-line agents in the treatment of precocious puberty. However, studies regarding the treatment effect on subjects with early puberty have reported inconsistent results. Design: A total of 14 studies identified from a search of electronic databases (AMED, EMBASE, MEDLINE and RISS) were included. Controlled studies with girls who developed puberty before 10 years of age and measurements of the adult heights of the subjects were selected. Studies using only long-acting GnRH agonists to suppress puberty were included. Adult height, duration of the treatment, age at the start of treatment and bone age advancement were analysed. Results: The mean age of the subjects ranged from 6.3 to 9.0 years. The meta-analysis showed a pooled mean difference in adult height of 3.2 cm and a 95% confidence interval of 1.3-5.1 cm. The height difference between the treated subjects and controls was significantly associated with the duration of treatment (P =.005) rather than the age at the start of treatment (P =.084) or the difference between bone age and chronological age (P =.427). Conclusions: Administration of GnRH agonists in girls who develop early puberty and demonstrate advanced bone age may be effective for increasing adult height, especially if a sufficiently long treatment duration can be achieved.
