胎儿体重与宫高腹围孕龄的回归关系

REGRESSIONAL RELATIONSHIP BETWEEN FETAL WEIGHT AND HEIGHT OF UTERINE FUNDUS ABDOMINAL GIRTH AND GESTATIONAL AGE

本文根据逐步回归原理,用IBM微型计算机分别探查宫高、腹围、孕周与胎儿体重的关系,求得预测胎儿体重的回归方程:男性体重(克)=71.9×宫高+28.2×腹围+6.2×孕龄天数-3485;女性体重(克)=105.6×宫高+10.2×腹围+1.5×孕龄天数-1678;男女体重合并简化方程=87.5×宫高+20.4×腹围+3.7×孕龄天数-2624。为临床方便,应用后一方程可预测胎儿体重。

With the help of IBM microcomputer, authors, basing on the principle of gradual regression, investigated the relationship between the height of uterine fundus (H) , the abdominal girth (G), the gestational age (A) and the new—born babys weight (W), Thus they obtain the equations for estimating the weight of feotuses as fouows: 1. For male:W = 71.9×H + 28.2×G + 6.2×A- 3485 (g);2. For female: W= 105.6×H+10.2×G+1.5×A-1678(g);3. For male and female (simplified):W =87.5×H +20.4×G +3.7×A-2624(g) According to the equation 3, they give the table of estimational fetal weight for clinic convenience.
