Data on heights and weights of 1150 children from 7 to 16 years of age of a Public School of Patiala have been utilized to show the existence of secular trend. The data were treated in five-yearly, decade-wise and twenty-five yearly groups. Heights show a positive trend of increase from 1950 to 1975. In weights, however, the trend of increase seems to have set in early 1970's. Therefore the present day children seem to have become linear as compared to their counterparts twenty-five years back.
已利用来自帕蒂亚拉一所公立学校1150名7至16岁儿童的身高和体重数据来表明长期趋势的存在。这些数据按五年、十年和二十五年分组处理。身高从1950年到1975年呈上升的积极趋势。然而，体重增加的趋势似乎在20世纪70年代初就已开始。因此，与25年前的同龄人相比，如今的儿童似乎变得更高了。
