SECOND-HAND SMOKE AND CHILDHOOD ASTHMA #19


We all know that smoking and asthma do not go together well. We see commercials on TV showing children (assumed asthmatics) breathing in second-hand smoke and not being able to go to school that day. According to a study reported in Pediatric Academic Societies, 53% of the asthmatic children in a survey conducted between 2003 and 2010 were exposed to second-hand smoke. The study also analyzed laboratory data which measured exposure to second-hand smoke in 972 children ages 6-19. Their findings were as follows:

v     Smoke exposure was associated with a 40% increase in the risk of having limitations on activity,. And there was a 40% increase in the risk of having one or more nights a week of disturbed sleep (compared with none) owing to wheezing.
v     Exposure was associated with a 20% increase in the risk of having one or two visits to the doctor’s office or emergency room because of wheezing in the past 12 months.
v     Smoke exposure was associated with a 40% increase in have one or more nights a week of disturbed sleep due to wheezing.
