SIgE reactivities to allergens in patients from different age
groups
In this paper, we classified the age into 10 groups as shown in Figure
1. Chi-square tests were conducted to test the differences among age
groups for each allergen. The analyzed results showed significant
differences (P<0.05 for tree pollen mix and P <
0.001 for the other eight allergens) among age groups for all allergens.
Furthermore, the prevalence of sIgE response to egg whites and cow’s
milk had very similar patterns among age groups. The positive rates
decreased as age increased. For crab, shrimp, house dust mites, dog
dander and German cockroaches, the positive rates are higher in the
middle age groups and lower in the upper and lower age extremes. The
troughs in prevalence of sensitization to these allergens were all
located in age group 0-3; however, it is the age group that has the
highest prevalence for egg whites and cow’s milk. The prevalence of sIgE
response to the mold mix was lowest in patients younger than 3 years
old, and the prevalence in other age groups was relatively stable.
