The size at birth was assessed of Saudi infants who were delivered in the main Maternity hospital in Riyadh and who represented a large proportion of infants born in the city. The mean (SD) weight, length and head circumference at birth of Saudi singletons were 3226 (534) g, 49.5 (2.0) cm and 34.5 (1.5) cm, respectively. Of all infants 5.9 percent were born preterm. The proportion of low birthweight infants was 7.9 percent, of which 44 percent were born at or past term. Teenage mothers had a low birthweight rate of 15.2 percent and primipara of 13.9 percent, however. Of all singletons 2.2 percent were small for gestational age and 3.7 percent of term infants had a Ponderal index less than 3rd percentile of the standard. During the final weeks of gestation the fetal growth rate was similar to that of Western populations. Compared with other developing countries the birth weight distribution was favorable and seemed to be influenced to a smaller extent than in these countries by socioeconomic and environmental factors.
对在利雅得主要妇产医院出生的沙特婴儿的出生时大小进行了评估，这些婴儿占该市出生婴儿的很大比例。沙特单胎婴儿出生时的平均（标准差）体重、身长和头围分别为3226（534）克、49.5（2.0）厘米和34.5（1.5）厘米。所有婴儿中5.9%为早产。低体重婴儿的比例为7.9%，其中44%为足月或过期产。然而，青少年母亲的低体重率为15.2%，初产妇为13.9%。所有单胎婴儿中2.2%为小于胎龄儿，3.7%足月儿的 ponderal 指数低于标准的第3百分位数。在妊娠最后几周，胎儿生长速度与西方人群相似。与其他发展中国家相比，出生体重分布较好，社会经济和环境因素对其影响程度似乎比这些国家小。
