Question

Quizplus · Accepted Answer

Very-low-birthweight infants are considered the most extreme case of prematurity as they weigh less than 1500 grams (3.3 pounds) at birth. They usually have a higher risk of health problems and developmental delays than other premature babies. Small-for-gestational-age infants, preterm infants, and low-birthweight infants may also have increased risks but do not necessarily have the same level of extreme prematurity as very-low-birthweight infants.
