OBJECTIVE
To study distance and velocity growth pattern of mid-upper-arm-circumference in Punjabi infants.
DESIGN
Longitudinal, monthly follow up.
SETTING
Growth clinic and homes of subjects.
SAMPLE
One hundred and fifty four (Male 86, Female 68) Punjabi infants weighing more than 2.5 kg at birth with gestation over 37 weeks.
METHODS
Every subject was measured for mid-upper-arm circumference between 1 to 12 months of age at one monthly intervals by the same investigator with a time tolerance of 3 days on the day of measurement.
RESULTS
Mid upper arm circumference showed rapid increase between 1 to 6 months whereafter, gain became slower during second half of infancy. It had grown by 34.9% in male and 40.2% in female infants between 1 to 12 months. Sex differences favoring male infants were statistically significant between 1 to 4 months. Monthly growth rates for arm-circumference depicted vascillatory pattern.
CONCLUSION
The values presented for arm circumference may be used as reference base to monitor growth of children during infancy.
目的
研究旁遮普邦婴儿上臂中部周长的增长距离和速度模式。
设计
纵向、每月随访。
地点
生长诊所及受试者家中。
样本
154名（男86名，女68名）旁遮普邦婴儿，出生时体重超过2.5千克，孕周超过37周。
方法
由同一名研究人员在婴儿1至12个月大时，每月测量一次上臂中部周长，测量时间误差在3天以内。
结果
上臂中部周长在1至6个月间增长迅速，此后在婴儿期后半段增长变缓。1至12个月间，男婴增长了34.9%，女婴增长了40.2%。1至4个月间，男婴在性别差异方面具有统计学意义。上臂周长的月增长率呈现出波动模式。
结论
所呈现的上臂周长数值可作为监测婴儿期儿童生长的参考依据。
