Pregnancy syphilis epidemic trends, clinical features, APOs risk factors, pregnancy-induced hypertension epidemics and related factors, in Northeast China Jilin Maternity Hospital 2013-2017

Abstract

Background. It is of great public health significance to monitor the global meiosis mother-to-child transmission plan proposed by WHO and monitor the prevalence of maternal syphilis and the factors affecting mother-to-child transmission. Methods. We collected 271 medical records of prenatally diagnosed (from 87286 pregnant women) of syphilis among pregnant women a maternity hospital in Jilin Province China from 2013 to 2017. The chi-square test and Logistic multiple regression analysis were used to describe the clinical characteristics of pregnant women with syphilis and the related factors of adverse pregnancy outcome. Results. The average prevalence of maternal syphilis is 0.31% (95%[CI]: 0.27%-0.35%). The mean age of 271 pregnant women with syphilis is 27.62±5.4 years old. The maternal syphilis prevalence of absence of paid occupation is 73.8%; rural population accounts for 43.6%. Maternal women with a history of abortion accounted for 43.1%, of which 53.1% had abortion ≥2; The average rate of treatment in pregnancy is 25.5% (95%[CI]: 25.4%-25.6%). The prevalence rate of APOs are 43.9% (95%[CI]: 38.1%-49.9%), declined in five years (P<0.05). APOs was significantly higher in women at 30–34 age group than that in 0-24 age group (OR= 2.916, 95%CI: 1.298-6.549) and higher in Un-treatment in pregnancy than that in receive treatment (OR=2.469, 95%CI:1.225-4.975). PROM occurrence (OR=2.702, 95%CI:1.219-5.988); CRP elevation (≥10 mg/L) and RPR high titer (≥1:8) are related to the occurrence of APOs. Abortion, prematurity and low birth weight are associated with no treatment during pregnancy (P<0.05). Comparison of 42 cases of pregnancy-induced hypertension and non-pregnancy-induced hypertension, Dysmenorrhea (OR= 3.654, 95%CI:1.812-7.369) and elevated urine protein (OR= 2.259, 95%CI:1.161-4.394) are the influencing factors of maternal syphilis complicated with pregnancy-induced hypertension. Conclusions. The prevalence of maternal syphilis in northern China is lower than that of 10 years ago, but the decline is still lower than that in the economically developed regions of the south. The rate of non-treatment of syphilis during pregnancy is high, and should be alert to the rebound of maternal syphilis.
