14 DAY TRIAL // After looking into the medical records of 600 mother-child pairs from China, researcher Jianghong Liu and his colleagues came to understand that kids exposed to secondhand smoke while still in the womb were more likely to develop various behavioral problems by the age of five.
Thus, Jianghong Liu and his fellow researchers are quite convinced that, should a mother be exposed to secondhand smoke for up to 30 minutes per day throughout the entire duration of her pregnancy, her offspring's chances of displaying behavioral problems later in life pretty much double.
The behavioral problems this research focused on referred to either the children's ability to pay attention, or to their being rather aggressive towards those around them, ZeeNews says.
Just for the record, these researchers neither asked mothers if they smoked during pregnancy, nor took into consideration the fact that some of these children were directly exposed to secondhand smoke shortly after being born.
