After 10 y of urban settlement, 680 Bedouin Arab children, who had had anthropometric assessment from birth (1981-1982) through early childhood, were reassessed in 1991-1992 to compare the rates of stunting in early and later childhood as well as to describe the factors influencing current height-for-age. Stunting had dropped from 32.7% at 18 mo to 7.2% at 10 y in the 1981 birth cohort and dropped from 17.5% at 9 mo to 8.2% at 9 y in the 1982 birth cohort. Based on a multiple-linear-regression analysis, height in early childhood and maternal height were statistically significantly and positively associated with current mean height-for-age in both cohorts. In the 1982 cohort socioeconomic status in early childhood was positively and current family size was negatively and significantly associated with current mean height-for-age. Thus, conditions that were present in early childhood had the largest influence on current height. In 1992, 10% and 6% of the infant siblings of the 1981 and 1982 cohorts, respectively, were stunted compared with 17% and 1% of the siblings aged 1-2 y of the respective cohorts. Therefore, the high rates of early childhood stunting in 1981-1982 appeared to be a birth cohort-specific phenomenon.
在城市定居10年后，对680名贝都因阿拉伯儿童进行了重新评估，这些儿童自出生（1981 - 1982年）起便接受了人体测量评估直至幼儿期，此次重新评估于1991 - 1992年进行，目的是比较幼儿期和儿童后期发育迟缓的发生率，并描述影响当前年龄别身高的因素。在1981年出生队列中，发育迟缓率从18个月时的32.7%降至10岁时的7.2%；在1982年出生队列中，发育迟缓率从9个月时的17.5%降至9岁时的8.2%。基于多元线性回归分析，两个队列中幼儿期身高和母亲身高与当前年龄别平均身高在统计学上均呈显著正相关。在1982年队列中，幼儿期社会经济地位与当前年龄别平均身高呈正相关，而当前家庭规模与当前年龄别平均身高呈负相关且具有统计学意义。因此，幼儿期的状况对当前身高影响最大。1992年，1981年和1982年队列中婴儿兄弟姐妹的发育迟缓率分别为10%和6%，而相应队列中1 - 2岁兄弟姐妹的发育迟缓率分别为17%和1%。所以，1981 - 1982年幼儿期发育迟缓的高发生率似乎是特定出生队列的现象。
