背景资料：世界各地频繁发生的地震和其他灾难性事件可被视为异常值，因此越来越迫切需要提高我们对此类灾害造成的负面影响的认识。地震可以强烈影响出生结果后的心理和形态发育的未出生的children，虽然详细的特点仍然hobby.Methods和Findings：我们利用出生记录在都江堰和彭州县调查的出生结果，作为一个大地震发生在汶川，中国在2008年5月12日。共记录新生儿13,003例，其中地震前6638例，地震后6365例。震后组低出生体重儿发生率高，新生儿Apgar评分低。出生性别比、出生身长、妊娠期长短差异无统计学意义。地震后出生缺陷率（1.18%）明显高于震前（0.99%），尤其是孕早期（1.47%）。出生缺陷谱在地震后发生了显着变化，耳部畸形的发生率显着增加。地震后早产率（7.41%）较震前（5.63%）显著增加。结论：汶川地震对出生结局影响显著，地震对出生结局有重要影响，地震是长期妊娠结局的重要监测指标。
Background: Earthquakes and other catastrophic events frequently occurring worldwide can be considered as outliers and cause a growing and urgent need to improve our understanding of the negative effects imposed by such disasters. Earthquakes can intensively impact the birth outcomes upon psychological and morphological development of the unborn children, albeit detailed characteristics remain obscure.Methods and Findings: We utilized the birth records at Du Jiang Yan and Peng Zhou counties to investigate the birth outcomes as a consequence of a major earthquake occurred in Wenchuan, China on May 12, 2008. Totally 13,003 of neonates were recorded, with 6638 and 6365 for pre- and post-earthquake, respectively. Significant low birthweight, high ratio of low birthweight, and low Apgar scores of post-earthquake group were observed. In contrast, the sex ratio at birth, birth length and length of gestation did not show statistical differences. The overall ratio of birth-defect in the post-earthquake (1.18%) is statistically high than that of pre- earthquake (0.99%), especially for those in the first trimester on earthquake day (1.47%). The birth-defect spectrum was dramatically altered after earthquake, with the markedly increased occurrences of ear malformations. The ratio of preterm birth post-earthquake (7.41%) is significant increased than that of pre- earthquake (5.63%). For the birth outcomes of twins, significant differences of the ratio of twins, birth weight, ratio of low birthweight and birth-defect rate were observed after earthquake.Conclusion: A hospital-based study of birth outcomes impacted by the Wenchuan earthquake shows that the earthquake was associated with significant effects on birth outcomes, indicating it is a major monitor for long-term pregnant outcomes.
