A Recent Study Links Second Hand Smoke to Eczema in Children and Severity of Eczema.
Babies born to mothers exposed to secondhand smoke during pregnancy raises their risk for developing eczema. Children in elementary school that were exposed to tobacco smoke while in their mother’s womb had a 50% higher chance at developing eczema and other skin diseases.
Scientists in South Korea studied elementary school children and determined through blood testing and questionaires that prenatal exposure to tobacco smoke raised the risk by 50% for allergic skin diseases such as eczema and dry itchy rashes.
Scientist drew blood from 3,639 children between the ages of 7-8 years old. The scientists discovered the children that had certain variant genes that affect immune proteins (TNF-alpha and TLR-4) had an even higher risk for eczema if they were exposed to second hand smoke while in their mother’s womb. Blood samples from 3,639 children ages 7 or 8 years old revealed that those carrying certain variant forms of genes that encode the immune proteins TNF-alpha and TLR-4 were even more prone to have eczema if they were exposed to second hand tobacco smoke.
Researchers also found that having one of the above variant genes and being exposed to second hand smoke can also cause the eczema to be more severe. This study was recently presented to the American Academy of Allergy, Asthma & Immunology by Soo-Jong Hong. Dr. Soo-Jong Hong is a pediatric allergist at the University of Ulsan in Seoul.
How do you apply this study to your life if you have eczema or your child has eczema? Quit smoking if you are pregnant or have a child or baby. Remove second hand smoke from your environment or your child’s environment. It is best to avoid homes that contain second hand smoke. It is also beneficial to avoid second hand smoke while you are pregnant.
