OBJECTIVE
To analyze the temporal trends in the fertility rate, proportion of antenatal consultations and caesarean sections in Brazilian adolescents aged 15 to 19, between 2000 and 2015. Methods: The fertility rate, proportion of prenatal consultations and proportion of routes of birth were calculated using data from DATASUS. The trend analysis was performed using the Prais-Winsten regression model and the annual percentage change.
RESULTS
There was a trend of reduction of 3.5% per year in the fertility rate among adolescents (p<0.05), in addition to an increasing trend of 6% per year in the proportion of more than six antenatal consultations (p <0.0001) and an increasing trend of 6.8% per year in the proportion of caesarean sections (p<0.0001).
CONCLUSION
Despite the decreasing trend in fertility rates among Brazilian adolescents, they remain high. Also noteworthy is the growing trend for caesarean sections, even with improved access to antenatal care.
目的
分析 2000 年至 2015 年巴西 15 至 19 岁青少年的生育率、产前检查比例和剖宫产率的时间趋势。
方法
利用 DATASUS 的数据计算生育率、产前检查比例和分娩途径比例。采用 Prais-Winsten 回归模型和年变化百分比进行趋势分析。
结果
青少年生育率呈每年下降 3.5%的趋势（p<0.05），此外，每年接受六次以上产前检查的比例呈 6%的上升趋势（p<0.0001），剖宫产率呈每年上升 6.8%的趋势（p<0.0001）。
结论
尽管巴西青少年的生育率呈下降趋势，但仍处于较高水平。值得注意的是，即使产前保健的可及性有所改善，剖宫产率也呈上升趋势。
