Linear growth is best estimated by serial anthropometric data or height velocity (HV). In the absence of recent data on growth velocity, we undertook to establish normative data in apparently healthy North Indian children.
Prospective longitudinal study in a representative sample of 7710 apparently healthy children, aged 3-17 years from different regions of Delhi. Height was measured at baseline and at 12 months while pubertal examination was performed at baseline in a subset of children.
The data on HV and puberty were available in 5635 participants (73.08%; 2341 boys and 3294 girls) and 1553 participants (622 boys; and 931 girls), respectively. The mean peak height velocity (PHV) was 7.82 ± 2.60 cm in boys seen at 12-12.9 years and 6.63 ± 1.81 cm in girls at 10-10.9 years Although late maturing boys had a greater HV than early or normal maturers, it did not vary with the age of pubertal maturation in girls. HV correlated with parental height in prepubertal boys, girls, and pubertal boys ( < 0.01) while no correlation was seen in girls.
The study presents normal height velocities in North Indian children. A secular trend was observed in achieving PHV in both boys and girls.
线性生长最好通过系列人体测量数据或身高速度（HV）来估计。在缺乏近期生长速度数据的情况下，我们着手建立明显健康的北印度儿童的规范数据。
对来自德里不同地区的7710名年龄在3至17岁的明显健康儿童的代表性样本进行前瞻性纵向研究。在基线时和12个月时测量身高，同时在一部分儿童的基线时进行青春期检查。
分别有5635名参与者（73.08%；2341名男孩和3294名女孩）和1553名参与者（622名男孩和931名女孩）获得了身高速度和青春期的数据。男孩在12至12.9岁时的平均峰值身高速度（PHV）为7.82±2.60厘米，女孩在10至10.9岁时为6.63±1.81厘米。虽然晚熟男孩的身高速度比早熟或正常成熟的男孩高，但在女孩中，它与青春期成熟年龄无关。在青春期前的男孩、女孩以及青春期男孩中，身高速度与父母身高相关（<0.01），而在女孩中未观察到相关性。
该研究给出了北印度儿童的正常身高速度。在男孩和女孩达到峰值身高速度方面均观察到了长期趋势。
