The relationship between birthweight (BW) and gestational age (GA) in 14,276 Danish children with GA of 35 to 42 completed weeks was illustrated employing 10%, 50% and 90% percentile curves. The curves were sex-specific. The number of light for dates (LFD) children defined by means of the 10% percentile (BW below 10th percentile) was 1,351 compared to 848 children when using the curve currently employed. The latter curve was based upon foreign children and moreover was not sex-specific. It is concluded that sex-specific and updated curves representing the population studied are mandatory in the diagnosis of LFD-children.
利用第10百分位、第50百分位和第90百分位曲线，对14276名孕龄在35至42足周的丹麦儿童的出生体重（BW）与孕龄（GA）之间的关系进行了说明。这些曲线是按性别区分的。通过第10百分位（出生体重低于第10百分位）定义的小于胎龄儿（LFD）数量为1351名，而使用当前采用的曲线时这一数字为848名儿童。后一种曲线是基于外国儿童的，而且没有按性别区分。得出的结论是，在诊断小于胎龄儿时，代表所研究人群的按性别区分的最新曲线是必不可少的。
