LONDON: Curbing outdoor air pollution may help prevent 2.7 million premature births a year, a condition that threatens children’s lives and increases their risk of long-term physical and neurological problems, scientists said on Thursday.

Fine particles in the air from diesel fumes, fires and other sources, may increase the risk of premature births — alongside other risks including a mother’s age and health — according to a study published in the Environment International journal.

“Air pollution may not just harm people who are breathing the air directly - it may also seriously affect a baby in its mother’s womb,” said Chris Malley, lead author of the study which is based on data for 2010.

The majority of premature births linked to air pollution occur in South and East Asia, the researchers said. India alone accounts for about 1 million premature births, and China for another 500,000.

Diesel vehicles, forest fires, crop burning, and cooking with wood, dung or charcoal, are major contributors to the problem, the researchers said.
