Clinical profile of patients of short stature presenting at endocrine clinic of national institute of child health Karachi

Objective: To determine the frequency of etiological factors in short statured patients presenting at endocrine clinic of National Institute of Child Health, Karachi.

Methods: This descriptive cross sectional study was conducted at Endocrine clinic of National Institute of Child Health, Karachi. One hundred children (48 boys and 52 girls) aged 3-15 years (mean 9.9±3.4) with short stature from January 2007 to July 2007 were evaluated during that period.

Results: Constitutional growth delay (CGD) and familial short stature (FSS) were identified as the most common, 55% of all short stature cases. Non-endocrinal causes as a single entity was detected in 17 children. Most common etiological factors in order of frequency were normal variant of growth (CGD, FSS), Hypothyroidism, Growth Hormone deficiency (GHD), and Celiac disease. GHD was found in 13% of total cases and it comprises 44% among endocrinal causes. Boys outnumbered girls with ratio of 2.7:1 (p < 0.05).

Conclusion: Most common cause of short stature was normal variants of growth as a group. Children with height falling below 0.4th percentile are more likely to have pathological cause.
