It was to develop smoothed height and weight percentiles for boys and girls with IDs between 7 and 17 years old.
The sample consisted of 1,047 young people (645 boys and 402 girls; 7-17 years old) with ID. A total of 4,059 measurements (height: n = 2,041; weight: n = 2,018) were retrospectively obtained from the period between 2013 and 2018. Smoothed height and weight percentiles were developed using the LMS method. Local and global diagnosis of percentiles were evaluated with Q statistics and detrended Q-Q plots.
Percentiles (5, 10, 25, 50, 75, 90, and 95) for height-to-age and weight-to-age were developed with satisfactory modeling in boys and girls between 7 and 17 years old. Boys showed a linear trend in height up to 11 or 12 years old, an increment from 13 to 15 years old and a deceleration from 15 or 16 years old. For the girls, height was linear between the ages of 7 and 11, followed by a deceleration from the age of 12 and without substantial changes from the ages of 15 to 17. Regarding weight, girls showed a linear trend of weight gain until the age of 13 and deceleration at the age of 14 or 15. Boys, however, showed a linear tendency to gain weight from 7 to 17 years old.
The height and weight percentiles developed in this study can help monitor the growth of young people with ID.
为7至17岁的智力残疾男孩和女孩制定平滑的身高和体重百分位数。
样本包括1047名7至17岁的智力残疾青少年（645名男孩和402名女孩）。回顾性收集了2013年至2018年期间的4059次测量数据（身高：n = 2041；体重：n = 2018）。使用LMS方法制定平滑的身高和体重百分位数。通过Q统计量和去趋势Q-Q图对百分位数进行局部和整体诊断评估。
为7至17岁的男孩和女孩制定了年龄别身高和年龄别体重的百分位数（第5、10、25、50、75、90和95百分位数），建模效果良好。男孩在11或12岁之前身高呈线性增长趋势，13至15岁身高增加，15或16岁后身高增长减速。对于女孩，7至11岁身高呈线性增长，12岁后身高增长减速，15至17岁身高无显著变化。关于体重，女孩在13岁之前体重呈线性增长趋势，14或15岁时体重增长减速。然而，男孩在7至17岁期间体重呈线性增长趋势。
本研究制定的身高和体重百分位数有助于监测智力残疾青少年的生长发育情况。
