Women who smoke during pregnancy have a greater risk of having a baby with renal impairment than mothers who stay away from cigarettes. To such conclusion scientists from the University of Kyoto in Japan.
Previously Smoking and pregnancy was associated with birth of premature babies and underweight children, as well as a wide range of congenital abnormalities. The new study expanded the list with kidney disease.
In addition to nicotine, cigarettes contain other harmful substances such as nitrogen oxide, polycarbonate, and carbon monoxide. Some of them pass through the placenta and disrupt the formation of the kidneys in the unborn child, said the head doctor Maki of Shinzawa.
Shinzawa and his colleagues studied on the subject of elevated levels of protein in the urine tests 44 and a half thousand children. It is the high protein levels can indicate impaired kidney function. Data on Smoking mothers were collected during a prenatal examination, women. Overall, 79% of women said they never smoked, and 4% stopped Smoking during pregnancy, and about 17% continued to smoke.

Compared to children born to non-Smoking mothers, children whose mothers smoked during pregnancy have a 24% higher risk to kidney damage. Urine tests showed elevated levels of protein in 1.7% of children born to Smoking mothers; at 1.6% of children whose mothers smoked in the past, and that 1.3% of children whose mothers have never smoked.
A new study has highlighted yet another reason why women should not smoke during pregnancy. Scientists sincerely hope that this will be enough.
