ABSTRACT

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.
