Article Abstract
Background: Gastroschisis is a common abdominal wall defect that increases infant mortality risk and health care costs. However, recent epidemiological data on gastroschisis in China is limited.
Methods: Using 2007-2020 data from the Chinese Birth Defects Monitoring Network (CBDMN), we analyzed gastroschisis prevalence rates stratified by birth year, maternal age group, residence area, geographical region, and infant sex. We also examined the temporal variations in prevalence, pregnancy outcomes of affected infants, prenatal diagnoses, and co-occurring anomalies.
Results: From 2007 to 2020, a total of 6,813 cases of gastroschisis were identified among 25,909,000 births, comprising 4,675 isolated and 2,138 non-isolated cases. Prevalence rates per 10,000 live and still births were 2.63, 1.80, and 0.83 for the overall, isolated, and non-isolated gastroschisis, respectively, all showing a decreasing trend over the study period. The prevalence of overall gastroschisis varied significantly by maternal age (< 20 years, 9.88/10,000; 20-24 years, 4.17/10,000; 25-29 year, 2.08/10,000; 30-34 years, 1.88/10,000;≥35 years, 2.24/10,000), maternal residence (urban, 2.45/10,000; rural, 2.85/10,000), geographic region (central, 2.54/10,000; east, 2.57/10,000; west, 2.80/10,000), and infant sex (male, 2.13/10,000; female, 1.79/10,000). Non-isolated gastroschisis cases had a higher early neonatal mortality rate than isolated cases (41.91% vs. 28.10%) and frequently co-occurred with musculoskeletal anomalies.
Conclusions: This study highlights a declining trend in gastroschisis prevalence in Chinese population, a contrast to previous studies, and underscores the need for improved perinatal management due to adverse pregnancy outcomes associated with this condition.

Association between maternal sexually transmitted diseases and birth defects in the United States: A nationwide population-based study.

Purpose: We estimated the association between maternal sexually transmitted diseases (STDs) and the risk of specific birth defects among live singleton births in the United States (US).
Methods: We conducted a population-based study using data from birth certificates for 14,602,822 live singleton births occurring from 2016 to 2019 in the US. We used logistic regression to estimate the associations between three maternal STDs (chlamydia, gonorrhea, and syphilis) and the risk of four specific birth defects (gastroschisis, cleft lip with or without cleft palate, spina bifida, and hypospadias), adjusting for socio-demographic and pregnancy-related factors.
Global birth prevalence of major congenital anomalies: a systematic review and meta-analysis.

Background: There is a lack of systematic review on the global prevalence of major congenital anomalies. We performed a systematic review and meta-analysis of population-based studies on global birth prevalence of eight major congenital anomalies (esophageal atresia, congenital diaphragmatic hernia, duodenal atresia, intestinal atresia, gastroschisis, omphalocele, Hirschsprung's disease and anorectal malformation).
Methods: Population-based studies reporting the birth prevalence of these anomalies were included from 1969 to 2024.

Background: Birth defects constitute a significant public health issue worldwide, yet there is a lack of comprehensive population-based data for the Chinese population.
Methods: We analyzed data from the China National Population-based Birth Defects Surveillance System from 2007 to 2021, we calculated the prevalence rates of selected birth defects, stratified by maternal residence, geographic region, maternal age, and infant sex. The Joinpoint regression model was utilized to assess trends and annual percent changes in prevalence.

Article Synopsis
- The study investigates the prevalence of birth defects using data from Hunan Province, China, between 2016-2020, highlighting the need for surveillance to inform preventive measures.
- Data analysis indicated that out of 847,755 births, there were 23,420 birth defects, revealing significant differences in total, perinatal, and livebirth prevalence rates.
- The total prevalence rate was identified as 27.63‰, while perinatal and livebirth prevalence rates were 17.06‰ and 13.52‰ respectively, with significant underestimations of these rates compared to total prevalence.
