广西不同胎龄儿生长指标的测量研究

A Research in the Growth Indexes of Perinatalas of Various Gestation in Guangxi

目的 探讨广西不同胎龄儿生产发育的状况 ,研究制定生长指标的参考值 ,为提高人口素质 ,降低不良儿的出生提供科学依据。方法 对广西 936 4例孕 14～ 42周单胎妊娠胎龄儿的身长、体重、顶臀长、手长、足长、双顶径、枕额径、头围、胸围、腹围进行测量研究 ,统计分析。结果 各项指标均随着胎龄的增长而增加 ,增长速度在孕 2 4周前大部份指标女稍大于男 ,2 5～ 2 9周发育基本平衡 ,30周以后男大于女 ,在孕 37周后各项指标增长速度减缓 ,41周停止 ,体重出现负值 ,32、 34周出现一个体重增长峰。结论 本研究结果基本反映了广西目前胎龄儿的体格发育现状 ,可作为今后监测广西胎龄儿发育状况的参考标准。

Objective Research in growth and development of different fetus physical growth in Guangxi Set up referential growth indexes,make the scientific basis for raising the quality of population and reducing unhealthy birth Method choosing 9346 single-pregnant fetus ranging from 14~42 weeks Measuring their body length,weight,hand length,foot length, biparietal diameter, occipitofrantal diameter,head circumference,chest circumference,abdomen circumference, diameter from head to buttocks,and processing the data with a computer Result The measurements showed that every index grows as the gestations grow, and mostly the growing rate of female is higher than that of the male before 24 weeks,They reach to the balance from 25 to 29 weeks,but after 30 weeks,the male is higher than the female There will be a regrowing summit behind 32 and 34 week regnancy After 37 weeks,the growth of all indexes slower,and stop after 41 weeks, the perinatals weight show negative Conclusion the result of the research can basically reflect the present physical growth situation of fetus in Guangxi So it can be regarded as referential standard supervising the different in perinatals growth in Guangxi
