There are many investigations that focus on women when it comes to relating the effects of tobacco with the respiratory health of the baby, but the role of man also influences, and much. And not only that the father smokes in pregnancy or in front of the baby, but also in the years prior to conception.
According to a study by researchers at the University of Bergen in Norway, smoking before becoming a parent increases the risk of asthma in the baby. It is the first human research that analyzes the link between a father's smoking habit before conception and the risk of his baby suffering from asthma.
It was performed with more than 13,000 men and women and several aspects were analyzed, such as the number of years a person had smoked before conceiving their baby, the incidence of asthma in children and if they had quit smoking before the conception of baby.
The conclusions showed that asthma was significantly more frequent in those children whose father had smoked before conceiving them. In addition, the risk increased if the father had smoked since he was 15 years old, and this increased as the years of being a smoker increased.
If a person smokes for a long time, their DNA is modified. Thus its genes are transmitted to the baby predisposing it to an increased risk of suffering respiratory conditions.
