Abstract
- Background: Cow's milk protein allergy (CMPA) is commonly seen in children. There have been no reports of the true prevalence of CMPA in Chinese infants. The aim of this population-based study is to determine the prevalence, clinical characteristics, and outcome of CMPA in Chinese infants.<br />Methods: We carried out a prospective survey in 7 participating hospitals throughout southern China. We included infants ≤12 months of age during the survey. For those suspected of CMPA, oral food challenge with cow's milk protein (CMP) was performed. A follow-up telephone interview was conducted at 12 months after the diagnosis to assess the clinical outcome of CMPA.<br />Results: A total of 9910 questionnaire surveys were distributed and 7364 (74.3%) were returned. The eligible survey number of surveys was 6768 (91.9%). A total of 182 infants was confirmed with CMPA, including 13 with anaphylactic reactions, 28 with clinical symptoms and serum immunoglobulin E (sIgE) >3.5 IU/mL, and 141 with positive CMP challenge test. The prevalence of CMPA was 2.69%. Infants with confirmed CMPA had significantly stronger family history of either 1 or both parents with food allergy, higher Cesarean section rate, and lower rate of breastfeeding, compared with those without CMPA. At 12-month telephone follow-up of 176 CMPA infants, 136 infants (77.3%) had become tolerant to CMP.<br />Conclusions: The prevalence of CMPA was 2.69%. CMPA infants had a strong family history of food allergy and atopy. Both Cesarean delivery and formula feeding were risk factors for CMPA. At 12-month follow-up, the majority of CMPA infants had become tolerant to CMP.<br /> (© 2018 American Society for Parenteral and Enteral Nutrition.)
