智力低下儿童骨龄与体格发育的研究

本文对93例智力低下儿童与305例智力正常儿童的体格发育及骨龄进行了对照分析,结果发现,约有半数智力低下儿童体格发育低下。骨龄延迟也多于对照组。智力低下越严重,体格发育低下越多。体格发育低下在环境及经济条件差的地区明显高于条件较好的地区,男性较女性多。另外,年龄越小,骨龄及体格发育低下越多,达青春期,部分可减轻或恢复正常。结合流行病学调查及临床x线检查,认为营养及环境可能是影响智力与体格发育的重要因素。

INVESTIGATION OF BONE AGE AND STATURE DEVELOPMENT IN MENTAL RETARDATION CHILDREN

A comparative analysis of bone age and stature development between 93 cases of mental retardation and 305 cases of mentally ormal children was made. About 50% of the cases mental retardation were associated with stature depression, The delay of bone age was longer in the mental retardation group than in the control group. The more severe mental retardation, the higher frequency the stature depression. Stature depression was more often seen in the areas where the environment and economic conditions are poor and in boys than in girls. The younger the mote frequency of the stature depression. When patients reached the age of puberty, some of the bone age delay and stature depression tended to get mild or could return to normal. Integrating the epidemiological investigation with the clinicoradiologic examination, we found that poor environment and undernutrition are significant factors for mental retardatio.
