Maternal pre-pregnancy body mass index and pregnancy outcome

Abstract

The mother's nutritional status both before and during pregnancy is an important factor that influences the evolution of pregnancy and the condition of the fetus and the newborn. Maternal weight, either through excess or deficit, is associated with a number of adverse pregnancy outcomes that can affect both mother and fetus. Knowing the maternal body mass index (BMI) and how it can influence the outcome of pregnancy is an important step in preconception care, and prompt nutritional intervention can prevent possible complications.
