According to study men who smoke since their adolescence may have chances of heart attack and nut just they also put their future children at more than 3 times higher risk of an early onset of asthma.
In this study more than 24,000 children were observed and it was found that father’s early smoking habits and smoking duration before conception increased non allergic onset asthma in kids. So it is advisable that if you a regular smoker than quit this habit else chances of asthma in your future children would be more and i am sure that no one want this situation to occur.
Professor Cesilie Svanes at the University of Bergen Norway said that the greatest increased risk for their children having asthma was found for fathers having their smoking debut before age 15. Also time of quitting before conception was not independently associated with offspring asthma.
It was also found in this study that the mothers who smoke during their pregnancy period had more chances of having asthma in offspring. However, no effect of maternal smoking only prior to conception was identified in the study and the difference from father’s smoking suggests effects through male sperm cells.
Cecilie further said that smoking is a known for causing genetic and epigenetic damage to spermatozoa and these are transmissible to offspring and also have potential to induce developmental abnormalities.
So it is advisable to men to quit this bad habit if they want their kids to be asthma free and have healthy baby. This study also investigated whether potential parental exposure to welding influenced asthma risk in offspring and the results suggested that they do have effect so smoking and welding both independently increased offspring asthma risk and any mutual adjustments done may not have any effect or did not alter the estimates of either.
