According to Imperial College-based Prof. Philip Steer, the Editor-in-Chief of the ‘British Journal of Obstetrics and Gynaecology’ chemicals in cigarettes change a pregnant woman’s body chemistry and distort the results of screening for disability in the fetus.
This puts women at high risk of miscarriage as they then have to undergo a further screening test for abnormality.
“The findings were further proof of damaging effects of smoking during pregnancy.
“Babies of mothers who smoke during pregnancy are small for gestational age and tend also to deliver earlier.
This research indicates smoking may also cause over-estimation of the risk of Down’s (Syndrome), thus exposing the mother to a higher risk of an unnecessary amniocentesis.”
