High temperatures could have an affect on babys' birth weights

Say scientists

Raw meat, pate and shellfish are all things that we are told to avoid during pregnancy.

However, it now seems something we can’t really get away from could also affect our unborn babies.

According to the latest research there is a link between air temperature and birth weight with an increase of 8.5 °C (47.3°F) in the last trimester associated with a 0.6 ounce (17g) decrease in birth weight of babies born full term.

To come up with this conclusion scientists at Ben-Gurion University of the Negev (BGU) and Harvard University used a ‘high resolution air temperature estimation model’ technique to predict daily air temperature in regions.

This was then used to analyse how women were exposed to differing temperatures from the minute they became pregnant to the birth of their babies.

Dr Itali Kloog at BGU said, ‘With the increase in temperatures over the last century and continued emissions from greenhouse gases, more attention is being focused on effects from heat.’

He said this piece of research was important with the climate becoming warmer as a result of these factors.
