Study of the Final Height in Children with Constitutional Short Stature

Short stature is one of the common problems in children. One of the common forms of short stature is Constitutional. Usually early diagnosis and treatment is worthwhile. We studied children with Constitutional short stature who came to the out-patient clinic of Pediatric Endocrinology in Loghman hospital between 2002 and 2008. Their final height has evaluated after puberty. SDS for the first and final height of the patients and their parent's height was calculated. Forty-nine patients (35 boys and 14 girls) were studied. Mean chronological age at the time of referral was 13.4±1.4 years, mean delay of the bone age 2.6±1.4 years, mean height 141.9±7.5 cm, mean SDS of the first height -2.69±0.69, mean parental height 163.8±3.9 cm and SDS for parental height was -0.85±0.47. Mean age at the time of evaluating final height was 18.7±0.5 years and mean SDS for the final height was -1.23±0.89 cm. All patients in our study reached their excepted final height. In this study final height of 9 patients (18.4%) was over 2 standard deviation lower than the mean of the community. Although, all of the patients reached to the normal range of final height, it was in the lower limit of the range. It seems medical interventions could be implemented for patients, whose first height was much lower than the mean.
