“Every cigarette counts,” stated Tatiana Anderson, a neuroscientist at Seattle Children’s Research Institute and a head author of a new study published relating SUID, sudden unexpected infant death, to smoking during pregnancy. The research analyzed more than 20 million births which included 19,000 SUID cases and concluded that one cigarette a day smoked by a pregnant woman can double the risk of SUID for her baby. In the United States, there are approximately 338,000 women each year who self-report they smoke during their pregnancy. The study also found that “if no woman smoked in pregnancy, SUID rates in the United States could be reduced substantially.” Ongoing studies analyzing exactly how SUID and smoking are related are being conducted and one possible theory is that smoking increases serotonin levels in infants during sleep which may affect the ability of the brain stem to regulate the respiratory system and therefore leads to SUID. There is also evidence that cigarette usage during pregnancy poses an increased possibility of childhood asthma, infantile colic, and childhood obesity. Women who my face addiction to smoking during pregnancy are encouraged to reach out and get help and support in order to prevent the increased risk of SUID for their child.
