Background: It is not yet clear whether the adult height (AH) is affected by the onset of puberty at 6 or 7 years old in girl in China.

Objective and hypotheses: To evaluate AH in girl with the onset of puberty at 6 or 7 years old.

Method: The standard of AH in girl was considered that their bone ages were equal to (or greater than) 15 years old or they were at least 3 years post-menarche. Eighty-two girls with the onset of puberty at 6 years old (A group, n=32) and 7 years old (B group, n=50) met the standard of AH, who received no treatment. AH of 69 girls with normal puberty were assigned to normal control group (C group). And above-mentioned girls were from Wuxi City, Jiangsu Province, China.

Results: The chronological ages in A and B group were (6.46±0.35) years and (7.59±0.25) years respectively. And the target heights were (158.66±3.83) cm and (159.33±3.93) cm respectively. And the AH were (161.73±5.60) cm and (161.24±4.99) cm respectively. The target heights and AH in C group were (158.33±4.02) cm and (161.43±4.51) cm respectively. There was no difference (P>0.05) for AH or target heights between C group and A group, or C group and B group.

Conclusion: AH is not affected by the onset of puberty at 6 or 7 years old in girl in Wuxi City, Jiangsu Province, China.
