Low birthweight

Children and adults with a low birthweight have been reported to be at increased risk of wheezing, respiratory infection and lung function abnormalities. This is true regardless of whether the low birthweight was the result of in utero growth retardation or premature birth. Despite antenatal and post-natal prophylaxis, small-for-gestational age infants, compared with those born with an appropriate birthweight for their gestational age, had worse neonatal and infant respiratory outcomes. There are modifiable risk factors of respiratory disease in those born with low birthweight: for instance, smoking has been reported to be more common in low birthweight adults.
