Autism linked to Grandmother's smoking habits

A study was performed on participants all born in the 90's. There were a total of 14,500 participants in the expirement done by The Univeristy of Bristol. The research found that if a girl's maternal grandmother had smoked during pregnancy, she was 67% more likely to display traits found in Autism like poor communication skills and repitive behavior. This disovery shows that if a female is exposed to cigarette smoke while still in the womb, it could affect the developg eggs. Since the expirement was carried out over many years on these specific children, other factors could be ruled out such as environmental and/or lifestyle. Professor Marcu Prembay stated " thered is DNA damage that is transmitted to the grandchildren or there is some adaptive response to the smoking that leaves the grandchild more vulnerable to ASD." Therefore, the affect of smoking is more powerful on the mother's child's offspring, then their own.

This is interesting because the results show the ability of a health concern to be passed down not only to offspring, but the next generation. This is relevant because while most people believe it to be wrong to smoke while being pregnant, some people still do it because it does not always have obvious effects on their children. From this study we can now know that it will make grandchildren more succeptable to having autism all to smoking. Alot of people would not think of this at the time because they do not have their grandchildren in mind at the time they are pregnant with the child of that future grandchild. Also interesing to me is, that with this new research, scientists were unable to conclude why it was differentiated between sexes. Perhaps it may be linked to the different growth patterns within male and female adolesence. Hopefully, research such as this will better recognise the effects of exposures during reproduction for multiple generations. This article can be found on
