Abstract
OBJECTIVE: To assess height velocity and develop height velocity percentiles in 5-17-year-old Indian children; and to study the magnitude and age at peak height velocity. DESIGN: Mixed longitudinal study. SETTING: Private schools at Pune and Delhi. PARTICIPANTS/PATIENTS: 2949 children (1681 boys) belonging to affluent class aged 5-17 years (1473-Pune, 1476-Delhi). METHODS: Annual height and weight measurements from 2007 to 2013. Total 13214 height velocity measurements (7724 on boys). OUTCOME MEASURES: Height velocity percentiles (3rd, 10th, 25th, 50th, 75th, 90th and 97th) constructed using LMS chart maker. RESULTS: Age- and gender-specific height velocity percentiles were generated. Median height velocity in girls decreased from 5 to 8 years, increased to a peak of 6.6 cm at 10.5 years and then declined to 0.3 cm at 17.5 years. In boys, median height velocity reduced till 10.5, increased to a peak of 6.8 cms at 13.5 years and then declined to 1cm by 18 years. CONCLUSIONS: Height velocity percentiles in 5-17-year-old urban Indian children were constructed.
