This report deals with cross-sectional growth of sitting height (SH), subischial length (SL, estimated as height minus sitting height), height of the anterior superior iliac spine (HIS), and total arm length (TAL) of Bengali school boys (Calcutta), aged 7.0-16.0 years. Preece-Baines model 1 (PB1) fits to the cross-sectional means of the four traits estimate the average ages at maximum increment at 12.41 years for SL, at 12.43 years for HIS, at 12.97 for TAL, and at 13.74 years for SH. Maximum increment of the upper and lower segment of the body are reached at an earlier age in the present study than in a longitudinal analysis of semi-urban Bengali boys from the suburban area of Calcutta. Socioeconomic differences and secular trend might explain this shift towards earlier maturation.
本报告涉及7.0至16.0岁孟加拉男学生（加尔各答）的坐高（SH）、坐骨下长度（SL，估计为身高减去坐高）、髂前上棘高度（HIS）和总臂长（TAL）的横断面生长情况。Preece - Baines模型1（PB1）适用于这四个特征的横断面均值，估计SL在12.41岁、HIS在12.43岁、TAL在12.97岁、SH在13.74岁时达到最大增长的平均年龄。本研究中身体上下段的最大增长年龄比来自加尔各答郊区的半城市孟加拉男孩的纵向分析结果更早。社会经济差异和长期趋势可能解释了这种向早熟转变的现象。
