Abstract:Objective To investigate the distribution of birth weight and selected prenatal risk factors associated with the risk of low birth weight and macrosomia. Methods Birth weight data were drawn from electric medical records of Jishuitan Hospital. Prenatal factors including gestational age, baby sex, maternal age, gravidity, the month of birth, maternal ethnicity and residence region were analyzed for the association with the risk of low birth weight and macrosomia. Results A total of 1 857 singleton live births born from April 2013 to March 2014 were included. The mean birth weight was (3 360.8±435.6)g. The proportion of low birth weight was 1.9%, while macrosomia was 7.5%. Preterm birth was the main risk factor for low birth weight (odds ratio 121.75, 95% CI 54.62-271.39), and male newborns were more likely to be macrosomia (odds ratio 1.74, 95% CI 1.21-2.50). Conclusion This investigation suggests that macrosomia is a common medical problem.
