Changes in Sensitization Rate to Weed Allergens in Children with Increased Weeds Pollen Counts in Seoul Metropolitan Area
 
The prevalence of allergic diseases in children has increased for several decades.
We evaluated the correlation between pollen count of weeds and their sensitization rate in
Seoul, 1997-2009. Airborne particles carrying allergens were collected daily from
3 stations around Seoul. Skin prick tests to pollen were performed on children with allergic
diseases. Ragweed pollen gradually increased between 1999 and 2005, decreased after
2005 and plateaued until 2009 (peak counts, 67 in 2003, 145 in 2005 and 83 grains/m3/
day in 2007). Japanese hop pollen increased between 2002 and 2009 (peak counts, 212 in
2006 and 492 grains/m3/day in 2009). Sensitization rates to weed pollen, especially
ragweed and Japanese hop in children with allergic diseases, increased annually (ragweed,
2.2% in 2000 and 2.8% in 2002; Japanese hop, 1.4% in 2000 and 1.9% in 2002). The age
for sensitization to pollen gradually became younger since 2000 (4 to 6 yr of age, 3.5% in
1997 and 6.2% in 2009; 7 to 9 yr of age, 4.2% in 1997 and 6.4% in 2009). In conclusion,
sensitization rates for weed pollens increase in Korean children given increasing pollen
counts of ragweed and Japanese hop.
