Lots of smoking during pregnancy, even a single cigarette a day, doubles the risk of a baby unexpectedly dying suddenly, according to a study by Microsoft data scientists and researchers from the Seattle Children's Research Institute (USA).

For women who smoked an average of 1 to 20 cigarettes By day, the odds of a sudden death increased by 0.07 with each additional smoked cigarette. If women do not smoke during pregnancy, the authors of the study estimate that in the United States every year 800 of the approximately 3,700 deaths from sudden deaths could be prevented, reducing the rate by 22 percent.

The habit of smoking contributes to the risk of sudden death in babies. The researchers used computer modeling methods to analyze the maternal smoking habits of cigarettes in all United States births between 2007 and 201


Nearly 20 million Of the live births included in their analysis, more than 19,000 deaths were attributed to sudden death or accidental asphyxiation and strangulation in bed. In addition to general cigarette smoking, the researchers also observed how pre-pregnancy smoking and how to reduce or stop smoking during pregnancy influenced this risk.

Compared to half of pregnant smokers who did not reduce their habit of smoking. Women who smoke during pregnancy experienced a 12 percent decline in cigarette consumption in the third quarter. Successful cessation was accompanied by a reduction of 23 percent.

Their analysis also showed that mothers who had smoked three months before pregnancy and quit smoking in the first trimester still had a higher risk of sudden death from nonsmokers. "The most important thing is that women understand that smoking before and during pregnancy largely leads to further risk reduction," said the scientists in detail.

Microsoft's Chief Data Scientist, AI For Good Research Lab, Juan Lavista, co-author of the study, explains how the research team used Microsoft's Artificial Intelligence technology to better address the phenomenon of sudden death understand and possibly save lives.

"Using AI, we have developed machine learning models that have analyzed millions of birth and infant mortality data, including mothers' smoker histories, which allows us to do something that has not been done before: the effects of each additional cigarette to evaluate the sudden death.
