Indian Pediatrics. 1999 Mar; 36(3): 257-62http://imsear.searo.who.int/handle/123456789/8794OBJECTIVE: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.engAge FactorsAnthropometryArm --growth & developmentChild Development --physiologyChild, PreschoolFemaleFollow-Up StudiesHumansIndiaInfantLongitudinal StudiesMaleSex FactorsJournal Article
