Abstract:
ObjectiveTo study specific allergic IgG antibody test and its impact factors.MethodsA total of 1770 Qingdao residents were recruited in this cross-sectional study from January to October 2011.ELISA was used to test specific allergic IgG antibodies.Logistic regression was used for multifactor analysis.Results Of 1770 participants,9 individuals had insufficient data,resulting in a response rate of 99.5％.Identification rate of specific allergic IgG antibody was 60.0％ (1056/1761 ),and the most commonly seen allergic foods were crab (49.4％ ),egg (44.80％ ),ling (38.0％ ),shrimp ( 30.4％ ) and soy ( 22.2％ ).Intolerance to crab,egg,shrimp,creamery,com,and tomato showed gender difference ( x2 =18.978,P＜0.05 ).Serum level of allergic IgG antibody was increased with age [20 - 40 years:( 118.61 ±45.67) U/ml; 41-60 years:(166.57 ±55.82) U/ml; ＞60 years:(183.67 ±49.34) U/ml; x2=13.597,P＜0.01].In logistic regression,difference between individuals with normal body weight and obesity population ( OR =1.897,95％ CI 1.215 - 2.578 ) or between those with or without allergic history ( OR =0.780,95％ CI 0.648 - 0.912) was found.Conclusions Impact factor of food intolerance includes gender,age,constitution and body mass index.Six kinds of food intolerance are more common in women.41 -60 year group shows peak of food intolerance.No exposure to allergic food and antianaphylaxis may reduce the risk of food intolerance.
