The paper analyses growth velocity data of infants aged 0-11 months from Madura, Indonesia, with the aim of identifying the time of onset of linear growth retardation. Velocities were calculated as average velocities from mid-point intervals, so that they can serve as comparative information for further studies. Secondly, the relation between weight and length velocities is tested. Thirdly, growth velocities are related to birthweight, length at birth and ponderal index (PI = weight/height3 x 100 in g/cm3. The anthropometric information of infants is taken from two large longitudinal studies, East Java Pregnancy Studies Phase I and Phase II (EJPS I and II). These were conducted from August 1981 to December 1985 and January 1987 to December 1989, respectively, in two villages in Madura, Indonesia. The results support the following hypotheses: linear growth in the first year in Madurese infants shows two periods of deceleration. The early phase starts in the first month and is related to intra-uterine growth. It lasts up to about 4-6 months. Children with normal birthweight but with a low PI grow slowest in length after birth. The second period is towards the second half of the first year, when differences in linear velocity decrease with the references and velocity distribution change. Differences in weight velocity increase during this period. Factors outside the intricate fetal mother-child relationship could start to play a role.
本文分析了来自印度尼西亚马都拉的0至11个月婴儿的生长速度数据，目的是确定线性生长迟缓的开始时间。速度被计算为中点间隔的平均速度，以便它们可以作为进一步研究的比较信息。其次，测试了体重速度和身长速度之间的关系。第三，生长速度与出生体重、出生时身长和 ponderal 指数（PI = 体重/身高³×100，单位为g/cm³）相关。婴儿的人体测量信息取自两项大型纵向研究，即东爪哇孕期研究第一阶段和第二阶段（EJPS I和II）。这两项研究分别于1981年8月至1985年12月以及1987年1月至1989年12月在印度尼西亚马都拉的两个村庄进行。结果支持以下假设：马都拉婴儿第一年的线性生长显示出两个减速期。早期阶段始于第一个月，与宫内生长有关。它持续到大约4至6个月。出生体重正常但PI值低的儿童出生后身长增长最慢。第二个时期是在第一年的下半年，此时线性速度的差异随着参考值的变化而减小，速度分布也发生变化。在此期间体重速度的差异增加。复杂的胎儿与母亲关系之外的因素可能开始起作用。
