Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 2
Abstract
Objective To explore the influence of maternal blood donation before pregnancy on neonatal birth weight. Methods A total of 6 428 full-term (gestational age ≥37 weeks) singleton pregnant women in Ningbo Medical Center Lihuili Hospital and Ningbo Women and Children′s Hospital from January 2020 to October 2020 were enrolled in this study. The cumulative whole blood donations before pregnancy were obtained through Alipay software. The relevant data of parturients and their fetuses were collected from electronic medical records. Results The maternal blood donation rate in Zhejiang Province before pregnancy was 14.69%. The average age of women was 29 (27-32), and the median of cumulative blood donation (except 0 mL) before pregnancy was 300 mL. Univariate analysis showed that there was no significant difference in neonatal gender, neonatal birth weight, proportion of low birth weight infants and proportion of macrosomia among non blood donation group, low blood donation group and high blood donation group (P>0.05). After multiple linear regression analysis, it was found that there was no correlation between blood donation before pregnancy and the neonatal birth weight (B=0.123, 95%CI: -1.013-8.461, P>0.05). Multivariate Logistic regression analysis showed that, compared with the non blood donation group, the occurrence of macrosomia was higher in both the low blood donation group and the total blood donation group (OR=1.366, 95%CI: 1.007-1.766, P<0.05; OR=1.369, 95%CI: 1.019-1.851, P<0.05). Conclusion Maternal blood donation before pregnancy may not be related to neonatal birth weight, but may be related to the probability of macrosomia in their offspring.
