Parents smoke, children are prone to miscarriage

Their parents and their daughters may be at risk of miscarriage later . A new finding by the University of Michigan School of Public Health.

According to research by US experts, girls who are exposed to cigarette smoke from their parents can grow to 80% more likely to miscarry when compared to children whose parents do not smoke.

Scientists have known for a long time that cigarette smoke can harm babies and children, such as low fetal body weight, asthma-born babies . But according to Dr. John Meeker, assistant professor Professor of Environmental Health at the University of Michigan School of Public Health, this is the first study to show a link between tobacco smoke exposure in adolescence and the risk of adult miscarriage.

This study was conducted for 2,162 pregnant women, non-smokers and have received supportive treatment for reproduction. The results showed that pregnant women who had been exposed to tobacco smoke from their parents had an 80% increased risk of miscarriage compared to women whose parents did not smoke.

Speaking to Reuters news agency, Dr. Meeker said that the finding is consistent with many previous studies that show that children exposed to harmful agents, including smoke, will cause effects. obvious health in adulthood.

The team found that the risk of miscarriage in women increased relative to the level of smoking of a parent, and the highest risk was recorded in girls with both parents smoking.

There is still no clear mechanism to cause miscarriage in children exposed to cigarette smoke, passive smoking. However, Mr. Meeker said in cigarette smoke contains thousands of chemicals, including those known or suspected to be harmful to reproductive health, such as lead, benzene and cadmium.

According to the research team, children are the most vulnerable reproductive health object when exposed to these toxic substances, because in the teenage years, the reproductive system of humans is in the development and completion stages. good.

Meeker explained: 'Childhood is a very sensitive period of physical development. During that period, the body is easily affected by toxic substances in the living environment. ' 'Children of smokers can be exposed to very high levels of tobacco smoke in their homes, in cars or elsewhere'.

According to Meeker, there have been ' enough ' scientific evidence to say that children need to be protected from the risk of passive smoking. He stressed: ' Preventing exposure to cigarette smoke not only protects our children's health, but also our children' children .

The study of Mr. Meeker and colleagues was published in the American Journal of Epidemiology on September 1, 2007.
