To construct centile charts for birth weight, length and head circumference for infants born from 24 to 42 weeks of gestation and to compare with the other national and international growth charts.
Observational descriptive study.
All consecutively live born singleton infants from 24 to 42 weeks of gestation.
Data were retrieved for the birth weight, length and head circumference of infants born from July 1999 to October 2009. Smoothened percentile curves were created separately for the male and female infants by Lambda Mu Sigma (LMS) method. The new curves were compared with the other Indian and international growth charts.
Raw and smoothened curves for weight, length and head circumference centiles at birth were created from 31,391 (males: 16,054 and females: 15,337), 28,812, (males: 14,730 and females: 14,082), and 28,790 (males: 14,724 and females: 14,066) infants, respectively. Females infants were lighter than the male infants, especially from 35 weeks onwards. On comparing the study curves with the other Indian growth curves, for infants less than 35 weeks, the mean birth weight for the study infants were similar or lower and for infants greater than 35 weeks, they were higher. On comparison of our weight centiles with the international data, across all gestations and across all centiles, our birth weights are lower.
The updated centile charts in this study may be used as reference charts for the birth weight, length and head circumference for the local population. Using earlier growth charts or the Western charts would misclassify the infants at birth into SGA or LGA.
构建孕24至42周出生婴儿的出生体重、身长和头围百分位数图表，并与其他国家和国际生长图表进行比较。
观察性描述性研究。
所有孕24至42周连续出生的单胎活产婴儿。
检索1999年7月至2009年10月出生婴儿的出生体重、身长和头围数据。采用Lambda Mu Sigma（LMS）方法分别为男婴和女婴绘制平滑百分位数曲线。将新曲线与其他印度和国际生长图表进行比较。
分别根据31391名（男婴：16054名，女婴：15337名）、28812名（男婴：14730名，女婴：14082名）和28790名（男婴：14724名，女婴：14066名）婴儿创建了出生时体重、身长和头围百分位数的原始曲线和平滑曲线。女婴比男婴轻，尤其是从35周起。将研究曲线与其他印度生长曲线进行比较，对于小于35周的婴儿，研究婴儿的平均出生体重相似或更低，对于大于35周的婴儿，平均出生体重更高。将我们的体重百分位数与国际数据进行比较，在所有孕周和所有百分位数中，我们的出生体重更低。
本研究中更新的百分位数图表可作为当地人群出生体重、身长和头围的参考图表。使用早期生长图表或西方图表会在出生时将婴儿错误分类为小于胎龄儿或大于胎龄儿。
