title: Low birth weight text: Low birth weight Low birth weight (LBW) is defined by the World Health Organization as a birth weight of a infant of 2,499 g or less, regardless of gestational age. Subcategories include very low birth weight (VLBW), which is less than 1500 g (3 pounds 5 ounces), and extremely low birth weight (ELBW), which is less than 1000 g (2 pounds 3 ounces). Normal weight at term delivery is 2500–4200 g (5 pounds 8 ounces – 9 pounds 4 ounces). LBW is either caused by preterm birth (that is, a low gestational age at birth, commonly defined as younger than title: Pound (mass) text: Pound (mass) The pound or pound-mass is a unit of mass used in the imperial, United States customary and other systems of measurement.

Although uncommon, it is occasionally also considered a unit of weight, equal to 1000 pounds, i.e., one half of a short ton. One use is as a unit of deadweight to compute shipping charges. The name comes from combining the words "kilo" and "pound"; it is occasionally called a "kilopound". Its symbol is kip, or less frequently, klb. When it is necessary to clearly distinguish it as a unit of force rather than mass, title: Birth weight text: requires special care. In the United States nearly half a million babies are born preterm because of this many of these babies also have low birth weights. There are four levels of care in the neonatal care units. Intensive Care, High Dependency Care, Low Dependency, and Transitional Care are the four levels: Children born with an abnormally low birth weight can have significant problems within the first few years of life. They may have trouble gaining weight, obtaining adequate nutrition, and supporting a strong immune system. They also have higher risks for mortality, behavior problems, and mental deficiencies.
