Taking account of the gestational age (28th to 42nd completed week of pregnancy) the sex-related ratio of birth weight to length (g/cm) for newborn infants is reported. This shows that observation of the correlation between birth weight and length with reference to gestational age makes a more accurate classification of newborn infants possible, rather than using a two dimensional classification (birth weight week of gestation).
考虑到孕周（妊娠满28周至42周），报告了新生儿出生体重与身长（克/厘米）的性别相关比例。这表明，参照孕周观察出生体重与身长之间的相关性，相较于使用二维分类法（出生体重×孕周），能够更准确地对新生儿进行分类。
