Neonates of low birth weight (LBW) have a birth weight of less than 2,500 g (5 lb 8 oz) and are mostly but not exclusively preterm babies as they also include small for gestational age (SGA) babies. Weight-based classification further recognizes Very Low Birth Weight (VLBW) which is less than 1,500 g, and Extremely Low Birth Weight (ELBW) which ...
Baby weighed as appropriate for gestational age. Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2] On average, babies of Asian descent weigh about 3.25 kilograms ...
Normal weight at term delivery is 2,500–4,200 g (5 lb 8 oz – 9 lb 4 oz). [citation needed] SGA is not a synonym of low birth weight, very low birth weight, or extremely low birth weight. For example, with a 35-week gestational age delivery, a weight of 2,250 g (4 lb 15 oz) is appropriate for gestational age but is still low birth weight.
Low birth weight may be a result of preterm birth. Low birth weight (LBW) is defined by the World Health Organization as a birth weight of an infant of 2,499 g (5 lb 8.1 oz) or less, regardless of gestational age. [1] Infants born with LBW have added health risks which require close management, often in a neonatal intensive care unit (NICU ...
A preterm birth, also known as premature birth, is defined as babies born alive before 37 weeks of pregnancy are completed. [40] There are three types of preterm births: extremely preterm (less than 28 weeks), very preterm (28 to 32 weeks) and moderate to late preterm (32 to 37 weeks). [40]
Weighing 11.9 ounces at 21 weeks, Richard Scott William Hutchinson, of Minnesota, broke the Guinness record as the most premature baby to survive.
A chart that allowed clinicians to plot a baby's birth weight against its gestational age became informally known as the "Lulagram". Before Lubchenco began her work, babies with low birth weights were referred to as premature.
Intrauterine growth restriction can result in a baby being small for gestational age (SGA), which is most commonly defined as a weight below the 10th percentile for the gestational age. [8] At the end of pregnancy, it can result in a low birth weight.
