Stature, sitting height and subischial length in a cross-sectional sample of 502 Jat-Sikh and 510 Bania females of Punjab ranging in age from 20 to 80 years, have been studied. It has been possible to separate out statural decrease due to ageing from secular effects by taking into consideration the subischial length, which is least affected by ageing. The rate of loss in stature obtained due to ageing is 0.0997 +/- 0.012 cm/yr in Jat-Sikh females and 0.127 +/- 0.012 cm/yr in Bania females. After adjusting the stature for ageing, the secular estimate obtained is 0.051 +/- 0.022 cm/yr in Jat-Sikh and 0.047 +/- 0.021 cm/yr in Bania females. The ageing and secular estimates obtained per year in both the communities are significantly different from zero at 5% level. The ageing estimate obtained per year is more in Bania females, whereas the secular estimate per year is larger in Jat-Sikh females, although non-significant.
对旁遮普邦502名年龄在20至80岁之间的贾特 - 锡克族女性和510名班尼亚族女性的横断面样本的身高、坐高和坐骨下长度进行了研究。通过考虑受衰老影响最小的坐骨下长度，有可能将衰老导致的身高下降与长期影响区分开来。贾特 - 锡克族女性因衰老导致的身高损失率为0.0997±0.012厘米/年，班尼亚族女性为0.127±0.012厘米/年。在对衰老因素进行身高调整后，贾特 - 锡克族女性的长期估计值为0.051±0.022厘米/年，班尼亚族女性为0.047±0.021厘米/年。两个群体每年获得的衰老和长期估计值在5%的水平上均显著不同于零。每年获得的衰老估计值在班尼亚族女性中更高，而每年的长期估计值在贾特 - 锡克族女性中更大，尽管不显著。
