根据中华儿科杂志1987年制定的小于胎龄儿的临床分型方法,对50例小于胎龄儿(SGA)进行了临床分型的分析。按照重量指数及身长与头围的比值两种方法进行分型,本组有43例分型为匀称型SGA,7例为非匀称型SGA。两种分型方法的符合率为86％。在匀称型SGA的43例中27例头围在正常范围,19例身长在正常范围,15例头围和身长均在正常范围。这似乎与匀称型SGA的情况不符合。因此,对目前SGA的临床分型方法尚需作进一步的观察。
According to the clinical classification of children less than gestational age established in 1987 by China Pediatrics, clinical classification of 50 small gestational age children (SGA) was analyzed. In accordance with the weight index and the ratio of length and head circumference of the two methods of classification, the group of 43 cases classified as symmetrical SGA, 7 cases of non-symmetric SGA. The coincidence rate of the two typing methods is 86%. Of the 43 cases with symmetrical SGA, 27 cases had head circumference in the normal range, 19 cases were in the normal range, 15 cases had head circumference and body length in the normal range. This does not seem to match the well-proportioned SGA. Therefore, the current SGA clinical classification method needs further observation.
