Association of maternal age with adverse pregnancy outcomes
Background: Although maternal age might affect pregnancy outcomes, it remains unclear whether this relationship is linear or curvilinear and if it differs between nulliparous and multiparous women. We aimed to characterize the relationship between maternal age and risks of pregnancy outcomes in a diverse sample of Chinese singleton pregnant women and to evaluate whether the relationship varied by parity. Methods: We based this prospective multice…
Hospital variations in caesarean delivery rates
Background: The impact of China's use of caesarean delivery on global public health has been a long-term concern. The number of private hospitals is increasing in China and likely driving up caesarean delivery rates, yet specifics remain unknown. We aimed to investigate variations in caesarean delivery rates across and within hospital types in China. Methods: We retrieved data on hospital characteristics and national hospital-level annually aggre…
Cesarean delivery on maternal request and common child health outcomes
Background: Cesarean delivery vs vaginal delivery was reported to increase the risks of childhood obesity, pneumonia, anemia, and neurobehavioral disorders, but few studies were able to deal with the confounding biases associated with medical conditions indicating cesareans. This prospective cohort study aims to investigate the associations of non-medically indicated cesarean delivery on maternal request (CDMR) with these child health outcomes. M…
Gestational Diabetes Mellitus as an Effect Modifier of the Association of Gestational Weight Gain with Perinatal Outcomes
The association of gestational weight gain (GWG) with perinatal outcomes seems to differ between women with and without gestational diabetes mellitus (GDM). Whether GDM is an effect-modifier of the association has not been verified. This study aimed to assess the modifying effect of GDM on the association of GWG with perinatal outcomes. Data on 12,128 pregnant women (3013 with GDM and 9115 without GDM) were extracted from a prospective, multicent…
Effects of prenatal micronutrients supplementation timing on pregnancy‐induced hypertension
In this secondary analysis of data from a double-blind randomized controlled trial (clinicaltrials.gov identifier: NCT00133744) of micronutrient supplementation (multiple micronutrients [MMN], iron-folic acid [IFA] and folic acid [FA] alone), we examined the potential modifying effect of gestational age at enrolment on the association of antenatal supplementation and pregnancy-induced hypertension (PIH). We included 18,775 nulliparous pregnant wo…
Demographic variations and temporal trends in prenatal use of multiple micronutrient supplements in Beijing, 2013–2017
Objective: To provide updated information about demographic variations and temporal trends in the prenatal use of multiple micronutrient (MMN) supplements in the metropolitan areas of China. Design: Descriptive analysis of routine prenatal healthcare data between 2013 and 2017. Setting: Chaoyang District, Beijing, China. Participants: A total of 197 346 pregnant women who attended their first prenatal care visit and provided information about MMN…
Association between gestational weight gain and exclusive breast-feeding for the first 6 months postpartum in Chinese women
Objective The association between gestational weight gain (GWG) and exclusive breast-feeding (EBF) practices remains unclear. The present study evaluated the association between GWG and EBF in the first 6 months postpartum among primiparas in rural China. Design The study population was drawn from a previous randomized controlled trial, and the relevant data were obtained from an electronic, population-based perinatal system and a monitoring syst…
The Rates and Medical Necessity of Cesarean Delivery in the Era of the Two-Child Policy in Hubei and Gansu Provinces, China
Objectives. To describe the cesarean rates in different child policy periods and assess the medical necessity of cesareans during the 2-child policy period. Methods. We collected hospital-level aggregate data on 93 745 deliveries and individual-level data on 27 977 deliveries from 6 hospitals in the Hubei and Gansu provinces of China from 2013 to 2016. Experts in gynecology and obstetrics assessed the medical necessity of 1024 randomly selected c…
Prevalence of Oral Clefts among Live Births in Gansu Province, China
Background: Oral clefts (OCs) are common human birth defects. Children with OCs in underdeveloped regions are more likely to suffer from poverty and hardship in their future lives. Here, we attempted to estimate the prevalence of OCs among live births in Gansu Province in 2008 to understand the epidemiologic pattern of the disease. Methods: A cross-sectional study was conducted from January 2008 to December 2008 in Gansu Province. The live births…
C‐reactive protein increases with gestational age during pregnancy among Chinese women
OBJECTIVE: To examine the concentration of C-reactive protein (CRP) in relation to gestational weeks during pregnancy among Chinese women. METHODS: From a randomized control trial of prenatal supplementation with folic acid, iron-folic acid, and multiple micronutrients in China, we examined 834 pregnant women with CRP measured initially between 5 and 20 weeks and at follow-up between 28 and 32 weeks gestation. We calculated and plotted CRP geomet…
