Pregnant women who stop smoking with the habit during pregnancy gave birth to healthy children, and with the same weight as those of mothers who do not smoke. This goes on from a study of Nick Macklon University of Southampton (UK) at the European Society of Human Reproduction and Embryology meeting in Stockholm (Sweden), indicating that the negative effects of smoking, the baby on the way, you can "Cancel" if you quit the habit during pregnancy.
Decreased birth weight is the most common effect of smoking during pregnancy, which in some cases. Risk of preterm birth and disorders related to the development of the brain Mothers who smoke, the researchers said, have always been encouraged to give up smoking again and became pregnant, although until now there was little evidence that the object could have positive effects on the unborn child in the last minute.
The result comes from a study of 50 000 pregnant women from the University Medical Centre in Southampton from 2002 to 2010 were followed, the researchers identified seven groups of women - Non smoking, who for more than a year to before conception closing, which was less than a year before conception, which was confirmed after the pregnancy stopped, further comprising up to 10 cigarettes a day, between 10 and 20 per day, more than 20 stops per day -. and are the data collected, the parameters of the newborn
After adjusting the results for other factors known that the properties of the baby at birth - gestational age, weight and age of the mother and the socio-economic class - the researchers found that children whose mothers had stopped smoking during the period " periconceptional "- or the time when they thought they were pregnant or as soon as pregnancy is confirmed - they were was born with a birth weight were significantly higher in children who smoke whose mothers continue, and similar to the offspring of women who never even smoked. "Not only was birth weight is much higher than among children of mothers who had to continue to smoke, was - explained Macklon - but we also have found that babies born the same gestational age and the same head circumference than those achieved by women had never smoked.
