Reference data for 1 month increments in weight, recumbent length, and head circumference, at ages 1 to 12 months, have been derived from serial data for 351 full-term Canadian infants. This derivation was achieved by (1) fitting a family of three parameter mathematical models to the data for each infant, (2) using these models to estimate values 1 month apart (3) calculating 1 month increments from the status values of 1 month intervals, (4) obtaining the distributions of these increments, and (5) presenting the percentiles of these increments in tables and in figures. The 1 month increments decreased with age during infancy in each sex, and these increments tended to be more rapid for boys than for girls. It is suggested that these reference data are suitable for the assessment of growth rates in infants born at term in Canada or in the United States. They can be used to assist the early identification of deviations from expected growth rates for individuals and to compare population samples.
1至12个月龄婴儿体重、身长和头围每月增加量的参考数据，来自351名加拿大足月婴儿的系列数据。这一推导过程如下：(1) 对每个婴儿的数据拟合一组三参数数学模型；(2) 使用这些模型估计相隔1个月的值；(3) 根据1个月间隔的状态值计算每月增加量；(4) 获得这些增加量的分布；(5) 在表格和图表中呈现这些增加量的百分位数。在婴儿期，各性别每月的增加量均随年龄增长而下降，且男孩的增加量往往比女孩更快。建议这些参考数据适用于评估加拿大或美国足月出生婴儿的生长速度。它们可用于协助早期识别个体与预期生长速度的偏差，并比较不同人群样本。
