Natural births better for babies

Bacteria ... A scientist says babies benefit from being born
vaginally.


BABIES born by caesarean section are more vulnerable to asthma,
allergies and infection as they miss out on receiving their mothers'
good bacteria during birth, a scientist says.

Professor Patricia Conway, of the School of Biotechnology and
Biomolecular Sciences at the University of NSW, said babies delivered
vaginally received protective bacteria as they passed through the
birth canal. Left on the baby's skin, this bacteria could then
colonise the intestine and help inoculate newborns against hospital
bugs. Gut flora was also crucial for developing a balanced immune
system, Professor Conway said. "With a C-section, the newborn baby
misses an opportunity to pick up a lot of mum's good bacteria," she
said.

"This can have long-term health implications, as the development of a
good intestinal ecosystem is necessary for health and immunity to
allergies, from childhood right through to adulthood."

Professor Conway said emergency caesareans, performed after labour had
begun, meant babies did receive some of the beneficial bacteria,
particularly if the waters had broken. But elective caesareans were
''sterile'' and gave babies no chance to pick up any of the mother's
good bacteria.

However babies had other chances to receive their mother's bacteria,
during skin-to-skin contact directly after birth and if they were
breastfed.

Australian College of Midwives vice-president Hannah Dahlen said
babies born vaginally had the advantage of hormonal surges during
labour, which made them more wide-eyed and able to connect with their
mothers.

Both mother and baby experienced a surge in catecholamines - the fight-
or-flight hormone - during labour, making babies more alert at birth.

Recent studies had shown white blood cells in babies born by caesarean
were different to those born vaginally, potentially altering the way
their bodies responded to attacks on their immune systems for the rest
of their lives.

The studies could explain dramatic increases in rates of diabetes,
testicular cancer, leukaemia and asthma among babies born surgically,
Dr Dahlen said.
