OBJECTIVE
The aim of this study was to assess the rate of repeated pregnancy in adolescence and its association with early marriage and education level.
METHODS
This is a cross-sectional study conducted by searching the Live Births Data System. The study included all adolescents in the age group 10-19 years with live births from 2015 to 2019 (n=2,405,248), divided into three groups: G1: primiparas; G2: with 1 previous pregnancy; and G3: with two or more previous pregnancies.
RESULTS
Total repeated pregnancies remained stable, along the years. In the age group 10-14 years, the decrease in the period was from 5.0 to 4.7%, whereas in the age group 15-19 years, it was from 27.8 to 27.3%. Being married or in a stable union increases by 96% the chance of repeated pregnancy in the age group 10-14 years (p<0.001; OR=1.96; 95% confidence interval [CI] 1.85-2.09). In the age group 15-19 years, the chance of repeated pregnancy among the married or in stable union increased 40% (p<0.001; OR=1.40; 95%CI 1.39-1.41)). Girls aged 10-14 years with an education level of<8 years had a 64% higher chance of repeated pregnancy (p<0.001; OR=1.64; 95%CI 1.53-1.75), and among those aged 15-19 years, there was a 137% higher chance of repeated pregnancy (p<0.001; OR=2.37; 95%CI 2.35-2.38).
CONCLUSION
Repeated pregnancy in adolescence in Brazil remains very high over the years. There is an association between low education level and early marriage with repeated pregnancies in adolescence.
目的
本研究旨在评估青少年重复妊娠率及其与早婚和教育水平的关系。
方法
这是一项通过搜索活产数据系统进行的横断面研究。研究对象为 2015 年至 2019 年期间年龄在 10-19 岁之间的所有活产青少年（n=2,405,248），分为三组：G1：初产妇；G2：有 1 次既往妊娠；G3：有 2 次或更多次既往妊娠。
结果
多年来，总重复妊娠率保持稳定。在 10-14 岁年龄组，这一比例从 5.0%下降到 4.7%，而在 15-19 岁年龄组，这一比例从 27.8%下降到 27.3%。早婚或稳定的婚姻关系使 10-14 岁年龄组重复妊娠的机会增加了 96%（p<0.001；OR=1.96；95%置信区间 [CI] 1.85-2.09）。在 15-19 岁年龄组，已婚或稳定婚姻关系中重复妊娠的机会增加了 40%（p<0.001；OR=1.40；95%CI 1.39-1.41））。10-14 岁女孩受教育程度<8 年，重复妊娠的几率增加 64%（p<0.001；OR=1.64；95%CI 1.53-1.75），而 15-19 岁女孩重复妊娠的几率增加 137%（p<0.001；OR=2.37；95%CI 2.35-2.38）。
结论
多年来，巴西青少年重复妊娠率仍然很高。低教育水平和早婚与青少年重复妊娠有关。
