In Chile, 14 to 16% of births occur in teenage mothers. These mothers apparently have a higher frequency of premature labor, low birth weight and congenital malformations.
To assess the frequency of prematurity, congenital malformations and weight at birth among the offspring of adolescent mothers.
The births occurred in a hospital between 1982 and 2001, were analyzed using the Latin American Collaborative Study for Congenital Malformations (ECLAMC) data base. Mothers were classified as teenagers when their age ranged between 10 and 19 years old and older when their age was over 20 years old. All women were subdivided as cases and controls.
The sample was formed by 894 teenage and 806 older mothers. Seven percent of both teenage and older mothers had offspring with one or more malformations. The incidence of low birth weight newborns and of prematurity was also similar in both groups of mothers.
In this sample, offspring of teenage mothers do not have a higher frequency of malformations, low birth weight or prematurity.
在智利，14%至16%的婴儿由青少年母亲所生。这些母亲早产、低体重出生和先天性畸形的发生率明显较高。
评估青少年母亲后代的早产、先天性畸形和出生体重的发生率。
对1982年至2001年在一家医院出生的婴儿进行分析，使用拉丁美洲先天性畸形协作研究（ECLAMC）数据库。母亲年龄在10至19岁之间的被归类为青少年母亲，年龄超过20岁的为年长母亲。所有女性被细分为病例组和对照组。
样本由894名青少年母亲和806名年长母亲组成。青少年母亲和年长母亲中均有7%的后代患有一种或多种畸形。两组母亲中低体重新生儿和早产的发生率也相似。
在这个样本中，青少年母亲的后代畸形、低体重出生或早产的发生率并不更高。
