摘要

本研究是收集臺灣中部某教學醫院1976年至1987年（缺1980年）間，35919名活產新生兒中不同懷孕週數的低出生體重兒（LBW）及極低出生體重兒（VLBW）之比率及出生體重／身長比。根據結果顯示，LBW及VLBW的比率分別為百分之6.3及百分之1.1。就LBW的比率而言，由懷孕第33週起快速降低至38週時已降至百分之6.9。而VLBW自懷孕28週後快速降低，自32週後已降至百分之9.3。出生體重（公克）／身長（公分）比由懷孕第28週的2.94增至第39週的6.25。男嬰與女嬰間無顯著差異。本研究嘗試由低出生體重／身長比率提出一檢定之常模。

A study of 35,919 live neonates was conducted from 1976 to 1987 (excluding 1980) at a teaching hospital in Central Taiwan. Our goal was to determine the proportions of low birth weight (LBW) and very low birth weight (VLBW) and birth weight/birth length ratios by gestational week.
The results showed that LBW and VLBW neonates were 6.3% and 1.1%, respectively . In LBW neonates groups, there was a rapid decline after the 33rd gestational week, then as low as 6.9% by the 38the gestational week. After the 28th gestational week, there was a rapid decline in VLBW proportion, then a further decline to 9.3% at the 32nd gestationa1 week. Birth weight/birth length ratios were 2.94 and 6.25 at the 28th and 39th gestational weeks, respectively. There were no differences in birth weight/birth length ratios between male and female babies. Based on the above findings, we tried to set a norm from birth weight/birth length ratios by gestational week.
