Background One of the challenges that pediatricians face when examining birth defects is to understand the trends in its occurrence and provide clues to etiology. This study was undertaken to retrospectively assess the prevalence of 10 common neonatal congenital malformations by reviewing a database of all deliveries from 28 weeks up until 7 days of birth from January 1998 to December 2009 in Zhejiang Province, China. Methods Ten common neonatal congenital malformations were selected for analysis. The incidence and the Cochran-Armitage Trend were assessed via SAS9.2. A P value ≤0.05 was considered statistically significant. Results Of 83 888 perinatals, 374 (4.46‰) suffered from congenital heart diseases (CHD), 77 (0.92‰) from congenital hydrocephalus, 32 (0.38‰) from intestinal atresia/stenosis, 36 (0.43‰) from anorectal malformations, 149 (1.78‰) from kidney malformations, 139 (3.31‰) from hypospadias (male), 178 (2.12‰) from orofacial clefts (OFC), 188 (2.24‰) from polydactyly, 62 (0.74‰) from syndactyly, and 269 (3.21‰) from accessory auricle anomaly. Their trend of prevalence varied as follows: CHD, P =0.0026; hydrocephalus, P =0.0042; intestinal atresia/stenosis, P =0.0103; anorectal malformations, P =0.4332; kidney malformations, P
