Abstract

Objective To investigate the prevalence of anemia and related risk factors in infants aged 6-12 months from rural areas of southern Shaanxi Province. Methods A questionnaire survey was used to collect the basic information on infants aged 6-12 months and their families from rural areas of southern Shaanxi Province, China. The content of hemoglobin was measured in these infants. A multivariate logistic stepwise regression analysis was performed to determine the risk factors for the development of anemia in infants. Results A total of 1 802 infants and their families participated in the survey, and there were 1 770 valid samples. A total of 865 infants (865/1 770, 48.87%) were found to have anemia. The multivariate logistic stepwise regression analysis showed that breastfeeding after birth (lack of scientific supplementary food) increased the risk of anemia in infants (OR=1.768, P < 0.01). Addition of supplementary food which met the criteria for minimum feeding frequency recommended by WHO (OR=0.779, P < 0.05) and formula milk feeding (OR=0.658, P < 0.01) were protective factors against anemia in infants. Conclusions In the rural areas in southern Shaanxi Province, anemia in infants aged 6-12 months is still a serious public health problem. Improper feeding can increase the risk of anemia in infants, and scientific addition of supplementary food is the key to reducing anemia in infants.
