Final answer:
A newborn weighing less than 1,000 grams would be considered underweight or low birth weight. These babies are more susceptible to disease and have a higher risk of mortality in infancy. They may also experience slow growth and developmental delays in early childhood.
Step-by-step explanation:
A newborn that weighs less than 1,000 grams would be considered underweight or low birth weight. Low birth weight is defined as a weight at birth of less than 2.5 kg (5.5 lb).
Low birth weight babies are more susceptible to disease and have a higher risk of mortality in infancy. They may also experience slow growth and developmental delays in early childhood.
In order to determine whether a baby is growing normally, their weight and length are measured and compared to standard values for infants of the same age during doctor visits.
