All singleton live births occurring in Singapore in the three years 1981-3 were computed, and birthweight was examined in the different ethnic groups (Chinese, Malay, and Indian). Overall the proportions of babies of very low birthweight (less than 1500 g) and low birthweight (less than 2500 g) were: Chinese 0.3% and 6.1%, Malays 0.4% and 8.5%, and Indians 0.5% and 10.0%. The important finding was that in all gestational periods and virtually all maternal age and live birth order groups Indians had the highest proportion of very low and low birthweight babies. However for prematurity Indians at 6.7% had a higher rate than Chinese (5.1%) but lower than Malays (9.9%). Likewise for neonatal mortality Indians at 8.7 per 1000 live births were between Chinese (7.1) and Malays (9.1). The evidence seems to indicate that the reason for Indians having a higher proportion of low birthweight babies is partly ethnic/genetic, and the cut-off point of 2500 g should perhaps be lowered for babies from the Indian subcontinent when international comparisons are being made.
统计了1981年至1983年新加坡所有单胎活产情况，并对不同种族（华人、马来人和印度人）的出生体重进行了检查。总体而言，极低出生体重（低于1500克）和低出生体重（低于2500克）婴儿的比例分别为：华人0.3%和6.1%，马来人0.4%和8.5%，印度人0.5%和10.0%。重要的发现是，在所有孕周以及几乎所有产妇年龄和活产顺序组中，印度人极低和低出生体重婴儿的比例最高。然而，就早产率而言，印度人为6.7%，高于华人（5.1%）但低于马来人（9.9%）。同样，就新生儿死亡率而言，印度人每1000例活产中有8.7例，介于华人（7.1）和马来人（9.1）之间。证据似乎表明，印度人低出生体重婴儿比例较高的部分原因是种族/遗传因素，在进行国际比较时，对于来自印度次大陆的婴儿，2500克的临界值或许应该降低。
