We examined birthweight distribution in relation to gestational age from 25 to 42 weeks in a series of 3.526 single newborns and in whom reliability of gestational age was rigorously controlled. To verify the distribution normality the Shapiro-Wilk and the Kolmogorov tests have been applied. Birthweight data follow a gaussian distribution for each gestational age week. Therefore in the birthweight standards estimation the parametric method can safely be applied also when the series includes pathologic and preterm newborns.
我们在3526例单胎新生儿中研究了孕25至42周时出生体重与胎龄的关系，这些新生儿的胎龄可靠性得到了严格控制。为验证分布的正态性，应用了夏皮罗-威尔克检验和柯尔莫哥洛夫检验。每个孕周的出生体重数据均呈高斯分布。因此，在出生体重标准估计中，即使该系列包括病理状态和早产新生儿，也可安全应用参数方法。
