Impact of Cigarette Smoke In Lungs

Lungs Girls Easier Damaged Smoke

Cigarette smoke is known to be bad for the body, including children. But recent studies find negative effects of cigarette smoke to the lungs will be worse in girls than in boys.

Recent research conducted by the University of Cincinnati College of Medicine found that negative health effects from exposure to tobacco smoke in children affects girls more than boys, especially if from the beginning was to have allergic sensitization.





Epidemiologist who are members of the UC's Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) found that children who had allergic sensitization early (age 2) and exposed to cigarette smoke high level will be at greater risk of decline in lung function at age 7 years ,

In addition lung function in girls will be 6 times worse than boys although he was exposed to cigarette smoke exposure levels are the same and have the allergen sensitization.

"This study shows children who are sensitized by age 2 more likely to suffer the greatest lung deficits during childhood as a result of exposure to secondhand smoke," said Kelly Brunst, researchers from the division of epidemiology and biostatistics at UC, as quoted by ScienceDaily, Wednesday (28/3 / 2012).

This is the first study to look at the influence of gender on secondhand smoke exposure using an internal biomarker for secondhand smoke are cotinine (product of nicotine metabolism) in the hair.
The study was published online on March 21, 2012 in the scientific journal Pediatric Allergy and Immunology involves 476 children from birth do have the risk of allergies based on family history and look at the effects of environmental exposures on respiratory health.

After the researchers collected hair samples of each child at ages 2 and 4 years to measure the concentration of cotinine. At the age of 7 years carried out an examination of lung function and asthma. This is because exposure to secondhand smoke during childhood kankak has been linked to respiratory problems, decreased lung function and asthma.
"There may be a complex interaction between cigarette smoke and loss of lung function in children, it depends on the time of exposure and the 'total load' children receive," said Grace Lemasters, PhD, profesors environmental health and principal investigator at UC CCAAPS.
