Researchers found that for women who did not smoke at start of either pregnancy, there was no extra risk of small for gestational age baby in the second pregnancy compared to non-smokers, even if they smoked between pregnancies.
Published in 'PLOS One Journal', the findings of the study show women who smoked at the start of their first pregnancy were more likely to have a baby born smaller than expected in their second pregnancy compared to non-smokers. This was even the case where they reported quitting by the start of their second pregnancy.
The biological relationship between smoking during pregnancy and a baby's birth weight from the same pregnancy is well established. However, until now there has been limited evidence on the impact of maternal smoking on following pregnancies.
In this study, the researchers found that for women who did not smoke at the start of either pregnancy, there was no extra risk of a small for gestational age (SGA) baby in the second pregnancy compared to non-smokers, even if they smoked between pregnancies.
