To analyze the risk factors of high-risk pregnancy, the change factor conversion rate and pregnancy outcomes, summarize the experience of high-risk pregnancy management, make it rationalized and standardized, improve the health of pregnant women and perinatal children, and guarantee the safety of mother and baby.

The 6 472 pregnant women who were admitted to the hospital from January 2016 to March 2017 were screened for high-risk factors according to the relevant management methods and implementation rules of high-risk pregnancies, and systematic management of high-risk pregnant women was conducted.

Among 6 472 pregnant women, 1 610 pregnant women were high-risk pregnancies, and the incidence rate was 24.88%. Three or more high-risk factors accounted for 163 cases (10.12%), two high risk factors accounted for 391 (24.29%) , one risk factors accounted for 1056 cases (65.59%). The top five risk factors were abortion history, age, gestationathe or mild pre-eclampsia, preterm prematurity, and premature rupture of fetal membranes at more than 34 weeks. Among pregnant women with high risk, 249 cases (11.29%) were between 19 and 25 years old; 441 cases (18.27%) of 26-30 years old; 536 cases (36.49%) of 31-34 years old; 384 cases (100.00%) of the 35-year old. The incidence of high-risk pregnancy was closely related to age, and the incidence of high-risk pregnancy was 100% in patients over 35 years old, with the increase of age. The risk factors of hypertension, preterm birth, endocrine disease and prenatal hemorrhage could be change normal rates were 32.77% (58/177), 83.21% (109/131), 46.88% (45/96) and 83.13% (69/83) respectively. The age group with the highest cesarean section rate was ≥35 years old. The c-section rate gradually decreased with age. The age group with the highest vaginal assist rate was 31-34 years old high-risk pregnant women without obviously differences between groups; the highest perinatal mortality rate was ≥35 years old (P <0.05). The risk of eclampsia, puerperal infection and postpartum hemorrhage was significantly higher in maternal ≥35 years old than in other age groups (P <0.05).

There are many influencing factors of high risk pregnancy, screening, identification and management of the influence factors, attention to health education, to promote the hospital management and community management cooperation, strengthen the management of high-risk pregnancies, helps to reduce the risk of maternal severe adverse pregnancy outcomes, and improve maternal and infant prognosis.
