本文报道了广东地区105例胎儿4～8个月(太阴月)五个胎龄组的体重、身长、坐高、手长、脚长、枕额径、双顶径、头围、胸围和腹围等指标的数据。并对14～35周胎儿上述各项指标与受精龄的关系进行相关回归分析,表明这些指标与受精龄之间有着很好的线性回归关系,相关系数从0.87到0.95。多数大于0.91,t 检验表明,P 均<0.01。此外,体重分别与身长、坐高及头围之间亦有着很好的线性回归关系,相关系数均大于0.94,t 检验表明P<0.01。
This article reports the body weight, length, height, length, length, head length, occipitofrontal diameter, biparietal diameter, head circumference, chest circumference and abdomen of 105 fetuses of 4 ~ 8 months (lunar month) Wai and other indicators of the data. Correlation analysis was made between the above indexes and fertilization age in 14-35 weeks fetuses, which showed that there was a good linear regression relationship between these indexes and fertilization age. The correlation coefficient ranged from 0.87 to 0.95. Most were greater than 0.91, t test showed that P <0.01. In addition, there was a good linear regression relationship between body weight and body length, sitting height and head circumference. The correlation coefficients were all greater than 0.94, t test showed P <0.01.
