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).
In 2008 the rate of low birth weight was the highest in babies born to women younger than 15 years old (12.4%). [23] Women aged 40–54 had a rate of low birth weight at 11.8 percent. The lowest rates of low birth weight happened among babies whose mothers were between the ages of 25–29 years (4.4%) and 30–34 years (7.6%). [23]
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.
The rate of low birth weights in the Southeast could be partially due to the region's more significant Black population, whose infants are more likely to have low birth weight. Between 2020 and ...
Typically, people with primordial dwarfism are born with very low birth weights. After birth, growth continues at a much slower rate, leaving individuals with primordial dwarfism perpetually years behind their peers in stature and in weight. Most cases of short stature are caused by skeletal or endocrine disorders. The five subtypes of ...
Adults born preterm have higher all-cause mortality rates as compared to full-term adults. Premature birth is associated with a 1.2x to 1.6x increase in all-cause mortality rates during early to mid-adulthood. Those born extremely prematurely (22–27 weeks) have an even higher mortality rate of 1.9x to 4.0x. [3]
Weight-based classification further recognizes Very Low Birth Weight (VLBW) which is less than 1,500 g, and Extremely Low Birth Weight (ELBW) which is less than 1,000 g. [206] Almost all neonates in these latter two groups are born preterm.
Viability depends upon factors such as birth weight, gestational age, and the availability of advanced medical care. In low-income countries, more than 90% of extremely preterm newborns (less than 28 weeks gestational age) die due to a lack of said medical care; in high-income countries, the vast majority of these newborns survive.
