Percentile growth charts for head circumference of Punjabi infants (male 86 and female 68) measured serially at monthly intervals during the first year of life are presented. Besides, constancy of sample size and strict adherence to time tolerance limit of +/- 3 days, on the day of monthly measurements other factors considered responsible for the natural smooth course of the percentile grids are highlighted. The presented data would enable easy detection of infants with abnormal course of head growth.
本文展示了旁遮普婴儿（86名男性和68名女性）在出生后第一年每月连续测量的头围百分位数生长图表。此外，除了样本量的稳定性以及在每月测量当天严格遵守±3天的时间容忍限度外，还强调了其他被认为对百分位数网格自然平滑过程有影响的因素。所呈现的数据将有助于轻松检测出头围生长过程异常的婴儿。
