Levels of vitamin A , ferritin and bone calcium protein and nutritional status of infants in Qinba mountainous area

Objective To study the malnutritional status of micronutrients in infants in Qinba mountainous area.Methods By using stratified multistage sampling in Qinba mountainous area(including 3 countries and 10 rural areas),425 infants were investigated and analyzed(<3years) for physical status and dietetic structure.Serum ferritin(SF),bone calcium protein(BGP) and hemoglobin(Hb) were measured in 144 infants and serum vitamin A was measured in 123 infants.Results The abnormal incidence of serum ferritin,bone calcium protein,growth hormone,serum vitamin A and hemoglobin were 32.3%,28.6%,31.6% and 25.6%,respectively.The incidence of stunting,underweight and wasting were19.8%,24.3% and 7.6%,respectively.Conclusion The deficiency of infant's vitamin A,ferritin are related to the status of family economy,nanny's nutritional status,improper structure of diet and custom.
