Methods 144 cases of RRTI were compared with the same number of non-RRTI children and some investigative tables were draw in which there were 22 possible factors related with RRTI and then finished.The greater impacting factors have been selected gradually with regression and then were analyzed with conditional logistic regression.The immune function and microelement of 81 cases RRTI and 56 cases non-RRTI were tested and the consults were analyzed. Results The main factors for children RRTI have close relations with passive smoking during pregnancy ,suspected asthma ,erective care ,malnutrition and weather changes.IgG ,CD3 ,CD4 ,CD8 and 3 microelements such as calcium ,zinc and forum in blood obviously low.
