Low bih weight baby is the one whose bih weight is?

Less than 2500 g REF: Nelson essentials of pediatrics, 17th edition Low bih weight (LBW) infants, defined as infants having bih weights of less than 2500 g, represent a dispropoionately large component of the neonatal and infant moality rates. Although bihs of LBW infants make up only about 6% to 7% of all bihs, they account for greater than 70% of neonatal deaths. IUGR is the most common cause of LBW in developing countries, whereas most LBW in infants in developed countries is secondary to prematurity. Very low bih weight (VLBW) infants, weighing less than 1500 g at bih, represent about 1% of all bihs, but account for 50% of neonatal deaths. Compared with infants weighing 2500 g or more, LBW infants are 40 times more likely to die in the neonatal period; VLBW infants have a 200-fold higher risk of neonatal death. Extremely low bih weight, weighing less than 1000 g at bih.
