Abstract: Objective To analyze the clinical features and etiology of malnutrition infants, in order to improve clinical diagnosis and treatment, and to reduce the incidence of malnutrition in infants. Methods Clinical data such as basic information, symptoms, complication and auxiliary examination were retrospectively analyzed among 847 infants aged 0 to 3-year-old with medium and severe malnutrition in 2012-2015. Results Totally 395(46.6%) infants were in moderate malnutrition,and 452(53.4%) infants were in severe malnutrition.The birth weights of two groups were(2.95±0.58) kg and(2.64±0.67) kg respectively, both of which were lower than that of normal infants.Breast-feeding rates of two groups were 54.8% and 40.7%, and the complementary feeding was improper in some cases.The chief complaints were cough(46.9％),fever(28.9％),diarrhea(16.4％) and polypnea(15.7％).Children with moderate and severe malnutrition often are more likely to develop respiratory and digestive infection, congenital heart disease(CHD), congenital laryngeal cartilage dysplasia, cerebral palsy and electrolyte disturbance in the same time. Conclusions Malnutrition is a multifaceted disease.Attention should be paid to the prevention and treatment of infection and electrolyte disorders while actively seeking etiological factor for hospitalized children.
