Analysis of Correlation between Serum Biotin Level and Fetal Growth and Premature Delivery in Pregnant Women

Objective To explore the correlation between serum biotin level and fetal growth and premature delivery in pregnant women.Methods A total of 90 pregnant women admitted to the Tongchuan People’s Hospital from January to October 2019 were included in the observation group.In addition,90 healthy and non-pregnant women in the hospital were selected as the control group.The observation group was divided into early,middle and third trimesters according to different gestation periods.According to different pregnancy outcomes,the observation group was divided into the term infants group,the premature infants group and the SGA group,and the mean age,Body Mass Index(BMI)and the first delivery of the term infants,the premature infants group and the SGA group were compared.Biotin levels in peripheral blood serum and cord blood serum were detected by enzyme-linked immunosorbent assay(ELISA),and Pearson correlation analysis was used to explore the correlation between biotin levels and fetal growth and premature delivery.Results The serum biotin level of pregnant women remained low from the first trimester of pregnancy and was significantly lower than that of the control group(F=14.39,P<0.001).The serum biotin level in the full-term infant group was higher than that in the premature infant group and the SGA group,and the difference between the two groups was statistically significant(F=70.387,P<0.001).The serum biotin level in the peripheral blood of the term infant group was higher than that of the premature infant group and SGA group,and the difference between the two groups was not statistically significant(F=1.294,P=0.279).Biotin levels in cord blood were higher in the term infant group,premature infant group and SGA group than in peripheral blood,and the difference were statistically significant(t=4.214~12.188,all P<0.001).Pearson correlation analysis showed that serum biotin level was positively correlated with fetal gestational age(r=0.32,P=0.01).Conclusion During pregnancy,pregnant women may take appropriate biotin supplements to prevent abnormal fetal growth.
