To analyze the temporal trend and factors associated with adolescent pregnancy during ten years in Brasil.
Data were extracted from the Live Births Information System, of the Brazilian Health System and included information regarding live births from adolescent mothers from 2006 to 2015. The overall proportion of gestation in adolescence and the specific proportions according to the characteristics analyzed were calculated using the standardized reporting coefficients and the simple linear regression method. The study was approved by the ethics committee of the University of Southern Santa Catarina (UNISUL).
The general proportion of Live Births from adolescent mothers varied from 21.4% in 2006 to 18.1% in 2015. This reduction occurred because of the negative variation observed among mothers aged 15 to 19 years. The indigenous group was the only that did not present a reduction. There was an increase in the proportion of adolescents with between four and seven years of formal education and in the proportion of adolescents living with partners. There was a reduction in all Brazilian Regions and in large part of the Federation Units.
The analysis of the temporal trend identifies a reduction in the proportion of live births among adolescent mothers in Brasil. However, there is a growing trend among some specific groups.
分析巴西十年间青少年怀孕的时间趋势及相关因素。
数据取自巴西卫生系统的活产信息系统，包括2006年至2015年青少年母亲的活产信息。使用标准化报告系数和简单线性回归方法计算青少年妊娠的总体比例以及根据所分析特征的具体比例。该研究得到了南圣卡塔琳娜大学（UNISUL）伦理委员会的批准。
青少年母亲的活产总体比例从2006年的21.4%降至2015年的18.1%。这种下降是由于15至19岁母亲中观察到的负向变化。原住民群体是唯一没有下降的群体。接受四至七年正规教育的青少年比例以及与伴侣同住的青少年比例有所增加。巴西所有地区以及大部分联邦单位的比例都有所下降。
对时间趋势的分析表明，巴西青少年母亲的活产比例有所下降。然而，一些特定群体中存在增长趋势。
