背景：西方国家报道了许多双胞胎出生体重标准，而日本则很少。本研究的目的是提供出生体重、出生身长、胸围和头围参考值，阐明与这些身体尺寸参数相关的特征，并将我们的出生体重参考值与最近使用生命统计数据得出的日本双胞胎出生体重标准报告进行比较。方法：研究对象共1061对双胞胎，出生年份为1968年至1990年。数据来源于《双胞胎协议调查表》，询问双胞胎婴儿期生长发育情况，以及卫生福利部颁发的《母婴健康手册》。使用至少包含胎龄和四个项目之一的数据计算并平滑统计平均值、标准差和按胎龄选定的百分位数。结果：当未测量三个附加参数，尤其是胸围和头围时，出生体重明显轻于单胎。对于男女来说，孕龄均与体重、身长、胸围和头围依次相关。与单胎相比，双胞胎的出生体重差异显着，身长略有差异，而胸围和头围则无差异。目前的出生体重结果始终与日本使用生命统计数据得出的双胞胎出生体重标准相似。结论：双胞胎的生长标准，特别是出生体重，对于了解和评估双胞胎的宫内生长至关重要。
BACKGROUND: Numerous birth weight standards for twins have been reported in western countries, whereas little is in Japan. The aim of this study is to present birth weight, birth length, chest circumference, and head circumference references, clarifying features related to these body size parameters, and to compare our birth weight references with recent report of birth weight norms of Japanese twins using the vital statistics. METHODS: The subjects consisted of 1,061 twin pairs in total, with birth years ranging from 1968 through 1990. Data was obtained from the Twins Protocol Questionnaire, which asked for information about twins’ growth and development in infancy, and the “Maternal and Child Health Handbook,” which was presented by Ministry of Health and Welfare. Statistical means, standard deviations, and selected percentiles by gestational age were calculated and smoothed using data that contained at least gestational age and one of the four items. RESULTS: Birth weight was significantly lighter than that of singletons when three additional parameters, especially chest and head circumference, were not measured. Gestational age was correlated with weight, length, chest circumference, and head circumference, in that order, for both sexes. Compared with singletons, birth weight difference in twins was marked and slight difference was observed as to length, whereas no difference was observed as to chest and head circumference. The present results as to birth weight were consistently similar to the birth weight norms of twins using vital statistics in Japan. CONCLUSION: Growth standards for twins, especially as to birth weight, are essential to understand and evaluate intrauterine growth of twins.
