Abstract:
Objective : To explore the pregestational and gestational risk factors associated with small for gestational age infant (SGA) by dif-ferent degrees. Methods ¡¤ Mothers and single newborns delivered at Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from September 2013 to December 2016 were included. Multivariate Logistic regression was used to analyze the correlation between maternal preg-nancy and pre-pregnancy risk factors and the occurrence of SGA by different degrees. Results ¡¤ There were no statistically significant differ-ences in maternal age, number of birth, education level, incidence of preterm birth and fetal sex in SGA. Maternal body mass index (BMI), gesta-tional hypertension and accepting assisted reproduction were significantly correlated with SGA (all P<0.05). The incidence of moderate SGA in mothers with low pre-pregnancy BMI and gestational hypertension were 3.6 and 4.0 times higher than that of the mothers with normal BMI and blood pressure. The incidence of severe SGA in mothers receiving assisted reproduction was 6.4 times higher than that in those who did not. Mild SGA was not associated with the above risk factors. Conclusion ¡¤ Maternal low BMI and hypertension are the risk factors of moderate SGA and accepting assisted reproduction are the risk factors of severe SGA, and the risk factors of SGA by different degrees are not the same.
