Abstract:

Objective: To investigate the incidence and influencing factors of pregnancy complications in China. Methods: We recruited and interviewed women who had a live birth between 13 and 24 months after childbirth at 60 hospitals in 15 provinces (regions and cities) in the estern, central and western regions of China. Information on women′s demographic characteristics, occurrences of pregnancy complications, previous pregnancy and disease history, etc. was collected. We performed unordered multicategorical logistic regression to identify the influencing factors of pregnancy complications. Results: A total of 18 045 maternal cases were interviewed. The incidence of pregnancy complications was 25.04%. 8.98% women had internal diseases and/or surgical operations during pregnancy, 7.99% experienced abnormal fetus and/or appendages, 6.79% suffered pregnancy complications only, and 1.29% had abnormal labor and/or puerperium. The risk of pregnancy complications in Chinese women is associated with the age of pregnant women, the number of abortions, the number of deliveries and delivery method. Moreover, the probability of pregnancy complications varied between geographical regions in China. Conclusions: The incidence of maternal pregnancy complications in pregnant women in China is relatively high. Strengthening contraceptive services, reducing induced abortions, increasing the frequency of prenatal examinations for high-risk pregnancy patients, and strengthening pregnancy health care are recommended. It is recommended that those with severe pregnancy complications seek medical treatment/referral to tertiary hospitals, which can help reduce the risk of pregnancy complications and the severity of complications.
