Abstract：Objective To investigate the prevalence of allergic diseases in children aged 0-24 months in the Wuhu urban area of Anhui Province and risk factors for allergic diseases. Methods Cluster random sampling was performed to select 600 children aged 0-24 months and their mothers from the Wuhu urban area, and a questionnaire survey was conducted to collect the data of disease history, family history, mothers' conditions during pregnancy, and child-rearing situation. Univariate analysis and multivariate logistic regression analysis were performed for such data. Results Among the 597 children included in the analysis, 56 (9.4%) were diagnosed with allergic diseases in the past. The univariate analysis showed that the age, use of antipyretic and analgesic drugs, a history of allergy in the father or grandparents, and the consumption of fish, shrimps, crabs, and shellfish during pregnancy were significantly associated with past allergic diseases (P < 0.05). The multivariate logistic regression analysis showed that the age and a history of allergy in the father or grandparents were positively associated with past allergic diseases (OR=4.0-4.9, 2.7, and 2.4 respectively; P < 0.05), while frequent consumption of fish, shrimps, crabs, and shellfish during pregnancy was negatively associated with past allergic diseases (OR=0.3; P < 0.05). Conclusions A family history of allergy is an independent risk factor for allergic diseases in children aged 0-24 months in the Wuhu urban area of Anhui Province, while frequent consumption of fish, shrimps, crabs, and shellfish during pregnancy is a protective factor.
