Washington: Babies born to mothers with obesity and exposed to passive smoking are at a greater healthrisk because they reduce oxygen supply to the unborn child,doctors have said. A team led by pediatricians from the National ResearchCentre in Cairo have found that obesity and passive smokingare risk factors for the unborn child, Science Daily reported.
The researchers found that NRBC count was higher ingroups I and II compared to the control group III. They alsofound that maternal body mass index (BMI) and infant birthweight were significantly higher in group I. "Raised levels of NRBCs are indicative of a degradedoxygen supply to the baby during the pregnancy," ElBaky said.Tobacco smoke inhalation whether direct or indirect mayaffect the amount of oxygen reaching the unborn child, becausehaemoglobin is poorly oxygenated. Nicotine can also cause narrowing of blood vessels,vasoconstriction, and so reduce oxygen supply through thatmechanism too. The team speculates that even apparently healthy newbornsof obese mothers and passive smokers may suffer subtleeffects of the reduced oxygen levels during pregnancy. "We recommended that every effort to control maternalobesity and prevent exposure to tobacco smoke be made," theteam said. "Smoking regulations in the workplace and at home shouldbe enforced strictly for the well-being of our infants," theyadded. PTI
