目的：探讨矮小症患儿的病因分类及其骨龄落后情况。方法回顾性分析2009年1月至2014年12月住院治疗2132例矮小症患儿的临床资料。结果2132例矮小症患儿中男1333例、女799例，平均年龄(9.03±3.04)岁，平均骨龄(6.81±3.05岁)；完全性生长激素缺乏症324例(15.20%)，部分性生长激素缺乏症780例(36.58%)，多垂体激素缺乏症27例(1.27%)，甲状腺功能减低症13例(0.61%)，特发性矮小893例(41.89%)，低出生体质量儿19例(0.89%)；骨骼发育障碍8例(0.38%)，颅内肿瘤13例(0.61%)，慢性系统性疾病15例(0.70%)，染色体疾病40例(1.88%)。ANOVA分析显示，不同病因组骨龄落后情况不同，多垂体激素缺乏症、颅内肿瘤导致的矮小症骨龄落后较其余各病因组明显。生长激素峰值与骨龄落后值之间存在负相关关系。结论生长激素缺乏症是矮小症最常见病因。矮小症患儿普遍存在骨龄落后，骨龄落后值与生长激素峰值之间存在负相关关系，联合激素缺乏对骨龄的影响更为显著。%ObjectiveThe aim of this study is to analyze the etiology and status of bone age of children with short stat-ure.MethodsAnthropological and physical examination data were retrospectively collected and studied in 2132 children with short stature in the department of endocrinology between 2009 and 2014. Growth hormone (GH) levels were determined by ar-ginine-clonidine test. Bone age was determined by CHN scoring.ResultsAmong the 2132 patients, 1333 were males and 799 were females. Mean age is 9.03 ± 3.04 years old, mean bone age is 6.81 ± 3.05 years. Of them, 324 cases (15.2%) were diagnosed complete GH deifciency, 780 cases (36.59%) were partial GH deifciency, 27cases (1.27%) were multiple pituitary hormone de-ifciency, 13 cases (1.64%) were hypothyroidism, 893 cases (41.89%) were idiopathic short stature, 19 cases (0.89%) were small for gestational age (SGA), 40 cases (1.88%) were chromosomal disorders, etc. Signiifcant difference in age and bone age was found using t test (P<0.05). Signiifcant differences in Δage were found between etiological categories using ANOVA (P=0.000). Δage was signiifcantly and negatively associated with peak GH using Pearson's correlation.ConclusionsGH deifciency is the most common cause of short stature. Bone age of children with short stature is commonly delayed. Δage was signiifcantly and negatively associated with peak GH. Multiple pituitary hormone deifciency has a signiifcant effect on bone age. The etiology of patients with short stature cannot be determined just by bone age.
