Low birth weight is a result of preterm birth (PTB, short gestation <37 completed weeks), intrauterine growth restriction (IUGR, also known as fetal growth restriction), or both. The term low birth weight refers to an absolute weight of <2500 g regardless of gestational age.

Prevalence by birth weight (BW) of LBW babies. The primary causes of VLBW are premature birth (born <37 weeks gestation, and often <30 weeks) and intrauterine growth restriction (IUGR), usually due to problems with placenta, maternal health, or to birth defects.

2023年8月9日 · Very-low-birth-weight (VLBW) infants - those infants born weighing less than 1.5 kg - are particularly vulnerable to the these adverse outcomes. Most LBW and VLBW is a consequence of preterm birth, small size for gestational age, or both.

Low birth weight is caused by intrauterine growth restriction, prematurity or both. It contributes to a range of poor health outcomes; for example, it is closely associated with fetal and neonatal mortality and morbidity, inhibited growth and cognitive development, and NCDs later in life.

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 …

The term low birth weight (LBW) is defined by the World Health Organization as neonatal weight of less than 2500 g and can be further categorized into very low birth weight (VLBW, <1000 g) and micro preemie (birth weight of ≤500 g) [1]. The birthweight of an infant is an important indicator of maternal health and a useful marker of neonatal ...

极低出生体质量(very low birth weight，VLBW)儿是指出生体质量为1 000～1 499 g的新生儿，超低出生体质量(extremely low birth weight, ELBW)儿是指出生体质量<1 000 g的新生儿 。由于VLBW儿和ELBW儿出生体质量低且各脏器发育均不成熟，机体调节功能和存活能力低下，易发生 …

Very low birth weight is a term used to describe babies who are born weighing less than 3 pounds, 4 ounces. The main cause of very low birth weight is being born too early, called premature birth. Treatment for very low birth weight babies includes care in the NICU, temperature-controlled beds, and special feedings.

To examine the relationships between growth (birth to age 2 years) and developmental outcomes in children born with very low birthweight (VLBW). Motor and mental development in children born with VLBW were regressed on anthropometric measurements at birth, 9 months and 2 years using multivariable regression.
