尽管有标准的儿科发育量表和女孩比男孩更早走路的流行传说，但之前还没有发表过关于独立行走开始年龄的大规模评估。这项研究的目的是对一大群异质性正常儿童进行前瞻性流行病学评估，以确定性别、种族、出生顺序和社会经济状况对独立行走开始年龄的影响。研究队列包括986名儿童(575名男性，471名女性)。使用多变量协方差分析模型检验种族、性别、收入和出生顺序对步行年龄的影响。在控制了模型中的其他变量后，种族是唯一具有统计学意义的预测步行年龄的因素(p<；0.0001)，黑人儿童行走的年龄(10.9±2.1月)比白人儿童(11.6±2.3月)小。总体而言，模型中包含的自变量只能解释步行时年龄变异的2.5%。
Despite the standard available pediatric developmental scales and popular lore that girls walk at an earlier age than boys, no large-scale evaluation of the age of onset of independent ambulation has been previously published. The purpose of this study was the prospective epidemiologic evaluation of a large heterogeneous group of normal children to determine the effect of gender, race, birth order, and socioeconomic status on the age of onset of independent ambulation. The study cohort consisted of 986 children (575 male, 471 female). A multivariable analysis of covariance model was used to examine the effects of race, gender, income, and birth order on age at ambulation. After controlling for the other variables in the model, race was the only statistically significant predictor of age at ambulation (p < 0.0001), with black children walking at a younger age (10.9 ± 2.1 months) than white children (11.6 ± 2.3 months). Overall, the independent variables included in the model were only able to explain 2.5% of the variance of age at ambulation.
