Secular trend in stature and age at menarche among Punjabi Aroras residing in New Delhi, India.

The study was conducted on Punjabi Arora girls (n = 159) and their mothers to see the phenomenon of secular trend in stature and age at menarche. An increase in stature and decrease in age at menarche was reported when the data of daughters was compared with that of their mothers thereby indicating secular trend in these two parameters. Better living conditions, improved nutrition and medical facilities, changes in environmental and socio-economic factors may account for increase in stature and early biological maturation.
