Objective: To ascertain suspicious influential factors of child
food hypersensitivity (FH), to provide a clue of finding high-risk children
of FH and preventing it in early life.
Method: The
standard questionnaires were answered by the parents and the food skin
prick test (SPT) was taken for all 970 subjects. 11 indexes designed in the
questionnaires were analyzed with the unconditional Logistic regression
model.
Results: In the single factor analysis, 5 of 11
indexes were obviously significant and they were also significant in the
multi-factor stepwise regression analysis (P<0.05). Our study indicated that atopic
family history (OR95%CI =
1.157~2.336), suffering from cutaneous symptoms (OR95%CI = 1.278~2.902) and
use of supplementary food before 4 months (OR95%CI = 1.107~1.650) were the
risk factors of SPT; while the age (OR95%CI = 0.946~ 0.988)and the
knowledge of child FH in the parents (OR95%CI
= 0.160~0.411) were protective factors. There were no relationship
between sex, birth-weight, feeding pattern during the first three days of
life, mother smoking during pregnancy and the result of SPT.
Conclusions: Avoiding
all kinds of suspicious risk factors, reinforcing the management of
high-risk infants of atopic family history and educating people about FH
should be done in order to reduce the incidence of child FH.
