OBJECTIVE
To develop new gender-specific regression formulae to estimate fetal weight focusing on a particular weight range from 2,501 to 3,999 g.
METHODS
3,254 singleton pregnancies were included to generate new regression formulae for female and male fetuses, and to evaluate their accuracy.
RESULTS
In comparison with commonly used formulae, the new gender-specific and weight-range-specific method of fetal weight estimation provided greater accuracy. The mean absolute error was less than 7%.
CONCLUSIONS
When properly used, the new formulae can improve the accuracy of weight estimations in fetuses between 2,501 and 3,999 g.
目的
开发新的针对特定性别的回归公式，以估算体重在2501至3999克这一特定范围内的胎儿体重。
方法
纳入3254例单胎妊娠，以生成针对女性和男性胎儿的新回归公式，并评估其准确性。
结果
与常用公式相比，新的针对特定性别和特定体重范围的胎儿体重估算方法具有更高的准确性。平均绝对误差小于7%。
结论
正确使用时，新公式可提高体重在2501至3999克之间胎儿体重估算的准确性。
