1953年开始对爱丁堡妇产医院出生的不同出生体重的单胞胎和双胞胎的生长和发育进行前瞻性研究。样本选择、程序和前9年研究结果的细节在别处给出（Drillien，1964）。在1953年至1955年期间招募了596名婴儿的主要样本。因为体重1360克的婴儿比例很小。直到1960年，我继续收集这一极低出生体重组的幸存者，最后的样本是按出生体重分布的648名婴儿，如表1所示。现在，为了与现行惯例保持一致，重量组以公制单位表示。最终样品的约三分之一为2000 g。或出生时不足三分之一，2001-2500克，和三分之一正常体重对照组。按性别以及是否为单胎或多胎妊娠的样本分布见表II。表三列出了历年来样本的损失情况。最大的损失发生在生命的前2年。在1953-55年出生的原始组中，近80%的人在11-13岁时仍在调查中。本文描述了1953-55年出生的人在小学转学考试后，按出生体重、中学处理情况不同的障碍情况的发生率，并提供了1955-60年出生的人的小学处理和成绩的一些信息。
A prospective study of the growth and development of singletons and twins of different birthweights, born in Edinburgh maternity hospitals, was begun in 1953. Details of sample selection, procedure, and findings in the first 9 years of the study are given elsewhere (Drillien, 1964). The main sample of 596 infants was recruited in the years 1953-55. Because of the small proportion of infants weighing 1360 g. or less, I continued to collect survivors in this very low birthweight group until 1960, giving a final sample of 648 infants distributed by birthweight as shown in Table I. Birthweight groups are now given in metric measures to conform with current practice. Approximately one-third of the final sample was 2000 g. or less at birth, one-third 2001-2500 g., and one-third normal weight controls. Distribution of the sample by sex and whether resulting from single or multiple pregnancy is given in Table II. Table III gives losses from the sample over the years. The maximum losses occurred in the first 2 years of life. Of the original group born 1953-55 nearly 80% remained in the survey at 11-13 years. This paper describes the incidence of different handicapping conditions by birthweight, secondary school disposal following the transfer examination in primary school for those born 1953-55, and gives some information about primary school disposal and performance for those born 1955-60.
