Exposure to cigarette smoke as kids could lead to having children with asthma, a recent study shows. The findings of the study also indicate that the risk of asthma in childrenis increased even further if their fathers were previously exposed to second-hand smoke and subsequently took up smoking themselves.
The findings of the study, according to the researchers, emphasize how smoking can impair not just the healthof smokers and their children, but also the health of the smokers' grandchildren. Mr. Jiacheng Liu and Dr. Dinh Bui, both of the University of Melbourne in Australia, were the primary researchers of this study.
Data from the Tasmanian Longitudinal Health Study (TAHS), which was directed by Professor Shyamali Dharmage, served as the foundation for this study. The TAHS has been going on since 1968, making it one of the largest and longest running respiratory studies in the world.
For the purpose of this study, researchers looked at 1,689 Tasmanian children, as well as their dads and their grandfathers and grandmothers on their fathers' sides. They matched the data on whether the dads had grown up with parents who smoked when they were under the age of 15 with the data on whether the children had gotten asthmaby the age of seven years. They also included information regarding whether or not the dads smoked at any point throughout their lives.
According to Jiacheng Liu:
We found that the risk of non-allergic asthma in children increases by 59% if their fathers were exposed to secondhand smoke in childhood, compared to children whose fathers were not exposed. The risk was even higher, at 72%, if the fathers were exposed to secondhand smoke and went on to smoke themselves.
Shymali Dharmage also stated:
We can't be certain of how this damage is passed on through generations, but we think it may be to do with epigenetic changes. This is where factors in our environment, such as tobacco smoke, interact with our genes to modify their expression. These changes can be inherited, but may be partially reversible for each generation.
"It's possible that tobacco smoke is creating epigenetic changes in the cells that will go on to produce sperm when boys grow up," Dharmage added. "These changes can then be passed on to their children."
The next step for the researchers is to determine whether or not fathers who were exposed to second-hand smoke as children pass on an elevated risk of allergies or other lung problems to their children, as well as whether or not the increased risk of asthma remains into adulthood.


Professor Jonathan Grigg, who was not involved in the research but serves as the Chair of the Tobacco Control Committee for the European Respiratory Society, said:
Asthma is a common, long-term lung condition that affects children and adults and usually requires ongoing treatment. We already know that smoking and being exposed to second-hand smoke can increase asthma risk. This study adds to growing evidence that the damage caused by tobacco smoke can be passed on to children and even to grandchildren. We need to protect children from this damage with measures to discourage smoking and support to help smokers quit.

He regularly writes science articles and blogs for science news website and open access publishers OA Publishing London and Scientific Times. He loves to keep himself updated on scientific developments and convert these developments into everyday language to update the readers about the developments in the scientific era. His primary research focus is Plant sciences, and he contributed to this field by publishing his research in scientific journals and presenting his work at many Conferences. Shah graduated from the University of Agriculture Faisalabad (Pakistan) and started his professional carrier with Jaffer Agro Services and later with the Agriculture Department of the Government of Pakistan. His research interest compelled and attracted him to proceed with his carrier in Plant sciences research. So, he started his Ph.D. in Soil Science at MNS University of Agriculture Multan (Pakistan). Later, he started working as a visiting scholar with Texas A&M University (USA). Shah’s experience with big Open Excess publishers like Springers, Frontiers, MDPI, etc., testified to his belief in Open Access as a barrier-removing mechanism between researchers and the readers of their research. Shah believes that Open Access is revolutionizing the publication process and benefitting research in all fields.
