摘　　要：本文从初生新生儿体格发育四项指标(体重、身长、头围、胸围)探讨母亲较佳分娩年龄。研究结果表明≤23岁生育者,所分娩的新生儿体格发育四项指标均较>23岁各组落后;早产和过期产所占的百分率较>23岁各组增高。本文调查的结果,为我国制定优生与晚育的政策提供了一部分科学根据。A total of 24150 newborn infants and their mother's data collected from 15 cities of China were investigated by analysing the maternal age and the neonate birth weight, length, head circumference, chest circumference, crown-hip length and arm circumference. The purpose of this study is trying to find out a more scientific evidence for our government to draw up a proper policy for encouraging women to be pregnant at a mature age and eugenics. All the 24150 newborn infants were born in the hospitals of 15 cities including both north and south of China between Feb., 1986 and May, 1987. For comparison, five groups were divided according to the maternal age. The women who were delivered at age 20 or younger are illegal in China. The data were analysised by using ANOVA and X^2(?)test. The result'was showed in the Table. All the six indexes of neonatal physical development were the lowest in the illegal maternal age group as compared with the other groups. The difference were statistically significant (P<0.01). The indexes of length, head circumference, chest circumference and crown-hip length were lower in the younger maternal age group than those in the mature maternal age groups. The differences were statistically significant (P<0.05, P<0.01 respectively). All the indexes between the two mature maternal age groups were no significant difference (P>0.05). The percentage of premature infants was the lowest (5.73％) and mature infants was the highest (91.59％) in the mature maternal age group. Compared with the illagal maternal age group, the differences were respectively significant (P<0.05). The results of this study suggest that in the group of women aged 20 or younger, all physical development indexes of their babies were lower as compared with the women aged 21 or older, and the percentage of mature infant was the lowest as compared with the other age groups. In contrast, women aged 24 to 34, the neonatal physical development indexes were the best and the percentage of premature and postmature infants were the lo
