Secondhand Smoke and Pregnancy

Every time, a pregnant woman is exposed to smoking, her foetus is precariously exposed to meet with intra-uterine deaths, say experts. The pulmonologists testify that in a state like Kerala where the prevalence rate of smoking is high, such premature deaths will definitely be a recurring phenomenon.

“Around 1.5 lakh people die of passive smoking in the country. Hence, it will not be wrong to presume that intra-uterine deaths are happening in the state which has topped the country with high prevalence smoking rate than the national average,” said Dr Babu John Mathew, consultant general physician, Medical Trust Hospital.

Intra-uterine deaths usually happen when the mother is an excessive smoker. “But here, the scenario is different. Here, the prevalence of smoking in women is not as high as it is in other parts of the country. But if the child’s father is an active smoker, it is beyond doubt that the mother will be highly exposed to smoking,” he pointed out.

Dr Praveen Valsalan, secretary, Cochin Thoracic Society, pointed out that, when the world scenario is taken into account, almost half of the children regularly breathe air polluted by tobacco smoke in public places. “Over 40 per cent of children have at least one smoking parent and active smoking causes more than 6,00,000 premature deaths a year.

The scenario will not be much different in the state which is known for smoking. The curse of our state is that an in-depth study has not been initiated here so far,” he said. The medical literature states that intra-uterine foetal demise can happen due to smoking, said Dr Sheila Scaria, a gynaecologist based in Kochi . “Though we cannot identify such incidents easily, the chances of premature deaths in babies are high due to both active and passive smoking. The scenario will not be different in any part of the world which is exposed to smoking,” she said.

Asked if such deaths have been reported in any parts of the state, they said: “It is not easy to identify such deaths which is a major hurdle. No research or studies have been undertaken in this regard so far. Besides, it is a long-winding procedure. If any such death happens, the whole family history will have to be traced,” said Dr Babu John. He added that while most of the smokers are honest about smoking in Western countries, Keralites try to cover it up when it comes to initiating any study in this regard.
