Abstract

Objective: To analyze, at national and regional levels, the trend of proxy indicators for the progress toward the elimination of the vertical transmission of syphilis in Brazil.

Methods: This is an ecological study that assessed the annual percent change (APC) of indicators related to gestational and congenital syphilis.

Results: An APC of 11.15% was observed in the detection rate of gestational syphilis (95% confidence interval - 95%CI 2.78-23.19), with stability in congenital syphilis across all regions. There was a reduction of prenatal care coverage among pregnant women with syphilis (APC=-7.34%; 95%CI -10.15; -5.33), and also a decrease in late diagnosis of the infection (APC=-10.77%; 95%CI -14.29; -8.79).

Conclusions: We evidenced challenges in achieving the 2030 elimination targets, highlighting the need for adjustments in current public policies on syphilis prevention and control.

巴西妊娠期和先天性梅毒指标的时间分析：到2030年消除垂直传播？

目的：分析巴西在国家和地区层面上消除梅毒垂直传播进展的代理指标趋势。方法：这是一项生态学研究，评估了与妊娠期和先天性梅毒相关的指标的年变化百分比（APC）。结果：妊娠期梅毒检出率APC为11.15%(95%可信区间- 95% ci 2.78 ~ 23.19)，各地区先天性梅毒检出率稳定。梅毒孕妇的产前护理覆盖率下降(APC=-7.34%；95%可信区间-10.15;-5.33)，感染晚期诊断率下降(APC=-10.77%；95%可信区间-14.29;-8.79)。结论：我们证明了实现2030年消除目标所面临的挑战，强调了调整当前梅毒预防和控制公共政策的必要性。
