Our study results, taken together with existing literature, suggest an independent role of pre-pregnancy BMI as a determinant of infant birth weight, as well as complex relationships between pre-pregnancy BMI, gestational weight gain, and other maternal factors with fetal growth, as measured by size at birth. The results are of public health importance because pre-pregnancy BMI and gestational weight gain are modifiable risk factors of adverse pregnancy outcomes.
