Low birthweight


we don't hope we are baby birth with low weight, is dangerous!!
Low birthweight.
A baby’s low weight at birth is either the result ofpreterm birth (before 37 weeks of gestation) or of restricted foetal (intrauterine) growth.5 Low birthweight is closely associated with foetal and neonatal mortality and morbidity, inhibited growth andcognitive development, and chronic diseases later in life. Many factors affect the duration of gestation and of foetal growth, and thus, the birthweight. They relate to the infant, the mother or the physical environmentand play an important role in determining the infant’s birthweight and future health.

• For the same gestational age, girls weigh less
than boys, firstborn infants are lighter than
subsequent infants, and twins weigh less than
singletons;
• Birthweight is affected to a great extent by the
mother’s own foetal growth and her diet from
birth to pregnancy, and thus, her body
composition at conception;
• Women of short stature, women living at high
altitudes, and young women have smaller babies;
• Once pregnant, the mother’s nutrition and diet,
lifestyle (e.g., alcohol, tobacco or drug abuse)
and other exposures (e.g., malaria, HIV or
syphilis), or complications such as hypertension
can affect foetal growth and development, as
well as the duration of pregnancy;
• Mothers in deprived socio-economic conditions
frequently have low birthweight infants. In those
settings, the infant’s low birthweight stems
primarily from the mother’s poor nutrition and
health over a long period of time, including
during pregnancy, the high prevalence of specific
and non-specific infections, or from pregnancy
complications underpinned by poverty. Physically
demanding work during pregnancy also contributes
to poor foetal growth.
Low birthweight thus defines a heterogeneousgroup of infants: some are born early, some are born growth restricted, and others are born bothearly and growth restricted. It is generally recognized that being born with low birthweight is a disadvantage for the baby. see more information on http://www.who.int
