Low birth weight is defined as birth weight below how many grams?

• A. Less than 3000 grams
• B. Less than 2000 grams
• C. Less than 2500 grams
• D. Less than 3500 grams

Answer: (C)

Low birth weight is defined as birth weight below 2500 grams (about 5 pounds 8 ounces). This cutoff is used because infants under 2500 g have a higher risk of neonatal complications and mortality, making it a practical marker for identifying babies who may need closer monitoring and care. LBW can occur because the infant is preterm or because fetal growth was restricted, so the same weight threshold applies regardless of gestational age. The other options don’t define LBW: weights at or above 2500 g are not considered low birth weight, and much lower cutoffs describe more severe categories like very low birth weight or extremely low birth weight.
