Serial data from studies of infants at the University of Iowa and from the Fels Longitudinal Study were used to develop sex-specific percentiles for increments in weight and recumbent length for selected intervals during the first 24 months of life. Weight increments are presented for 1-month intervals from birth to 6 months, 2-month intervals from birth to 12 months, and 3-month intervals from birth to 24 months. Length increments are presented for 2-month intervals from birth to 6 months, and for 3-month intervals from birth to 24 months of age. Weights and lengths at the target ages were obtained for the Iowa data by simple interpolation, and for the Fels data by fitting families of three-parameter mathematical functions to the serial data from ages 1 to 24 months. The tabular presentations are based on the Iowa data from birth to 3 months of age, on the combined Iowa and Fels data from 3 to 6 months of age, and on the Fels data from 6 to 24 months of age. We believe that these reference data will be useful in screening for deviations from normal growth and may aid in early detection of failure to thrive or excessive weight gain during early life.
爱荷华大学对婴儿的研究以及费尔斯纵向研究的系列数据，被用于制定出生后头24个月内特定时间段体重和身长增长的性别特异性百分位数。体重增长数据呈现的是从出生到6个月每1个月的间隔、从出生到12个月每2个月的间隔以及从出生到24个月每3个月的间隔情况。身长增长数据呈现的是从出生到6个月每2个月的间隔以及从出生到24个月每3个月的间隔情况。目标年龄的体重和身长数据，对于爱荷华大学的数据通过简单插值法获取，对于费尔斯的数据则通过将三参数数学函数族拟合到1至24个月的系列数据来获取。表格呈现的数据基于爱荷华大学从出生到3个月的数据、爱荷华大学和费尔斯数据合并后的3至6个月的数据以及费尔斯从6至24个月的数据。我们认为这些参考数据将有助于筛查偏离正常生长的情况，并可能有助于早期发现生命早期的生长发育迟缓或体重过度增加。
