NEW YORK (Reuters Health) – Smoking a mother during pregnancy puts her children at risk of developing dementia and visual impairment, a recent Chinese study suggests.
The study was conducted by researchers at the Huazhong University of Science and Technology in China and published its findings Wednesday in the journal Acta Ophthalmologica.
The ulcer is an optical defect that makes the eyes in an unbalanced state, so that each eye turns to a different direction. One eye can focus forward, while the other eye deflects to the inside, outside, up, or down.
This imbalance can also be noticed in the eyes, and sometimes it sometimes disappears or disappears. This imbalance may be transmitted between the eyes.
Eyes also cause vision impairment, sometimes double vision and impaired vision, as well as "blurring" or "lazy eyes" resulting from the neglect of vision in one eye.
To investigate the relationship between maternal smoking and childhood injury, the team reviewed the results of 11 scientific studies conducted in this regard.
They found that maternal smoking during pregnancy was associated with a 46 percent increase in the risk of neonatal deaths, one of the most common eye diseases among children.
Maternal smoking was associated with 10 cigarettes a day during pregnancy, an increase of 79 percent in the risk of developing a disease among their children, researchers said.
"Smoking a mother is a public health problem, especially in developing countries, and has a major impact on birth control," said Dr Zukson Lo, head of the research team.
Previous studies have shown that women who smoke during pregnancy are more likely to have children with health problems, notably low birth weight, premature birth, birth defects and sudden infant death syndrome.
She pointed out that maternal smoking also affects the efficiency of the lungs in babies, which are major causes of infant mortality, as well as its negative impact on physical growth and maturity in adolescence.
For its part, the World Health Organization reported in its latest report that tobacco kills nearly 6 million people in the Eastern Mediterranean Region each year, including more than 5 million former and current tobacco users and about 600,000 non-smokers exposed to secondhand smoke. Smoking is one of the main causes of many chronic diseases, including cancer, lung disease, heart disease, and blood vessels.
