The aim of the present study was to measure the proportion of adolescent pregnancies in Montes Claros, Minas Gerais, Brazil. From a total of 7,672 live births in 2001, the estimated proportion of births by adolescent mothers was 21.5%. In addition to the limited presence of adequate frequency in prenatal visits, especially in the 10-14-year bracket (12.0%), the study identified an increase in the number of complications, inversely related to age, and these differences were significant in relation to prematurity and low birth weight, which did not occur with the 5-minute Apgar score. Confirming the hypothesis of greater frequency of these complications when the number of prenatal visits was inadequate, the outcomes also signal an age-associated risk, particularly in early adolescence (10-14 years). These results, together with the data on an increase in adolescent pregnancy in the region from 1997 to 2001, point to teenage pregnancy as a public health problem.
本研究的目的是测定巴西米纳斯吉拉斯州蒙特斯克拉罗斯市青少年怀孕的比例。在2001年总计7672例活产中，青少年母亲所生孩子的估计比例为21.5%。除了产前检查次数充足的情况有限，尤其是在10至14岁年龄段（12.0%），该研究还发现并发症数量有所增加，且与年龄呈负相关，这些差异在早产和低出生体重方面具有显著性，而5分钟阿氏评分方面则未出现此类差异。研究结果证实了产前检查次数不足时这些并发症发生率更高的假设，同时也表明了与年龄相关的风险，尤其是在青春期早期（10至14岁）。这些结果，连同该地区1997年至2001年青少年怀孕增加的数据，表明青少年怀孕是一个公共卫生问题。
