Research of influencing factors on neonatal body weight.

Objective:To discuss the possible influencing factors of neonatal body weight.Methods:To collect the data of body weight from 413 neonates,at the same time,the relations between pre-pregnant body mass index(BMI) and BMI again during pregnancy of mothers,the different educational attainments and the different age of mothers and nonatal body weight were analyzed.Results:(1) The BMI of mothers before giving birth and BMI again during pregnancy of mothers were statistically significantly correlated with the neonatal body weight(P0.05);(2) The differences between four neonatal groups came from different educational attainments of mothers weren't statistically significant during 12～14days(P0.05),While during other times it was statistically significant(P0.05);(3) The differences between four neonatal groups came from different age of mothers weren′t significant(P0.05).Conclusion:the body weight of neonatus increases along with the BMI of mothers before giving birth and the BMI again during pregnancy of mothers,mother′s educational attainments influence not only the neonatal body weight,but also the accumulative growth of body weight during neonate;The influence of mother′s age on neonatal body weight could be neglected.
