Growth of mentally retarded children differs from that of normal children. However, the adolescent growth and development of Indian mentally retarded children has not been studied.
This study was conducted to evaluate the physical growth and sexual development of adolescent mentally retarded girls in North Indian population and to compare it with that of normal girls of same age group.
One hundred mentally retarded (intelligence quotient (IQ) less than 70) and 100 normal girls between 10 and 20 years of age were categorized into 1-year age groups. Their height was measured and the sexual development was assessed based on breast development (BD) and pubic hair growth (PH) stages 1-5 on the basis of Tanner scale. The data was then compared between the two groups using Student's t-test. The mean age of menarche was calculated by applying Probit analysis.
The mean height of mentally retarded girls was significantly retarded as compared to normal girls at all ages; however, the mean height gain during 11-20 years was same in both the groups. The mentally retarded girls also showed significant retardation in PH growth at 15-17 years and in BD at 15-16 years of age.
The physical growth and sexual development of adolescent mentally retarded girls was retarded as compared to the normal girls. The physical growth retardation occurred during early childhood (before 11 years), however the retardation in sexual maturity occurred during middle adolescence, between 15-17 years of age.
智障儿童的生长发育与正常儿童不同。然而，印度智障儿童的青春期生长发育尚未得到研究。
本研究旨在评估印度北部人群中青春期智障女孩的身体生长和性发育情况，并将其与同年龄组的正常女孩进行比较。
将100名智障（智商低于70）和100名10至20岁的正常女孩按1岁年龄组进行分类。测量她们的身高，并根据坦纳量表基于乳房发育（BD）和阴毛生长（PH）的1 - 5期评估性发育情况。然后使用学生t检验对两组数据进行比较。通过应用概率分析计算初潮的平均年龄。
在所有年龄段，智障女孩的平均身高均显著低于正常女孩；然而，两组在11至20岁期间的平均身高增长相同。智障女孩在15至17岁时的阴毛生长和15至16岁时的乳房发育也明显滞后。
与正常女孩相比，青春期智障女孩的身体生长和性发育滞后。身体生长迟缓发生在幼儿期（11岁之前），而性成熟迟缓发生在青春期中期，即15至17岁之间。
