【Abstract】 Objective To survey the status of cow milk protein allergy (CMPA) in school age children, and to provide scientific basis for monitoring food allergy. Methods A total of 5 720 students from Xiangfang district in Harbin elementary schools were surveyed by questionnaire, skin prick test and German allergy screen test as a preliminary diagnosis. After that, influential factors related to milk protein allergy were analyzed by use of the collected data. Results One hundred and nintysix students had ever suffered CMPA at least once, 47 students showed positive reaction in skin prick test and German allergy screen test. The prevalence of CMPA was 0.82%. The major symptoms of CMPA were rash, followed by gastrointestinal allergy. In addition to CMPA, they were allergic to other food at the same time. Related factors on CMPA are feeding mode, other food allergy and parental allergy. Conclusion Comprehensive measures including breastfeeding,recommending low allergy baby for mula powder should be taken to prevent and control CMPA.
