A study in The Lancet medical journal found that
while the impact of anti-smoking laws varies between countries, the
overall effect on child health around the world is positive.
"Our research shows that smoking bans are an effective way to
protect the health of our children," said Jasper Been of the
University of Edinburgh's Centre for Population Health Sciences, who
led the study.
He said the findings should help to accelerate the introduction of
anti-smoking legislation in cities, countries and districts which
have yet to do so.
Laws banning smoking in public places such as bars, restaurants,
offices and other workplaces have already been proven in previous
studies to protect adults from the health threats associated with
According to the World Health Organisation (WHO), tobacco already
kills around 6 million people a year worldwide, including more than
600,000 non-smokers who die from exposure to second-hand smoke. By
2030, if current trends continue, it predicts tobacco's death toll
could be 8 million people a year.
Only 16 percent of the world's population is covered by
comprehensive smoke-free laws, and 40 percent children worldwide are
regularly exposed to second-hand smoke, the WHO says.
Public health experts hope that as more and more countries in Europe
and around the world adopt stricter legislation on smoking in public
places, the health benefits will swiftly start to become evident.
Friday's research in The Lancet, which analyzed data on more than
2.5 million births and almost 250,000 hospital attendances for
asthma attacks, was the first comprehensive study to look at how
anti-smoking laws affect children's health.

With results from five North American studies of local bans and
six European studies on national bans, it found rates of both
pre-term births and hospital attendance for asthma fell by 10
percent within a year of smoke-free laws coming into effect.
"Together with the known health benefits in adults, our study
provides clear evidence that smoking bans have considerable public
health benefits for perinatal and child health," said Been.
He said it also provided "strong support for WHO recommendations to
create smoke-free public environments on a national level."
