Abstract:
Objective:To understand the status of anemia among rural children aged 3-6 in central China and its relationship with dietary behavior, and to provide reference for prevention and intervention of anemia in rural children.
Methods:From April to June 2021, stratified cluster sampling was used to select 1 246 preschool children aged 3 to 6 years old in rural areas in central China. Peripheral blood of the ring finger was collected. Dietary behaviors regarding consumption of cereals and potatoes, fruits, vegetables, soy products, milk, animal foods, food diversity, and drinking water were investigated. Logistic regression analysis was used to analyze the association between anemia and dietary behaviors.
Results:The detection rate of anemia in rural children aged 3-6 in central China was 13.88%. The anemia detection rate of left behind children (19.00%) was higher than that of non left behind children (11.27%), and the difference was statistically significant ( χ 2=13.93, P <0.01). Logistic regression analysis showed that the proportion of left behind children ( OR=1.28, 95%CI =1.16-1.56) with anemia was higher than that of non left behind children ( P <0.01). Consumption of animal food intake ≥3 times/week ( OR=0.82, 95%CI =0.69-0.91), and ≥2 kinds of vegetables ( OR= 0.86, 95%CI =0.71-0.93) were associated with lower rate of anemia ( P <0.05).
Conclusion:The detection rate of anemia in rural children aged 3-6 years in central China is relatively high, especially in left behind children. Dietary literacy of caregivers should be further improved regarding increased intake of animal foods and vegetables to reduce the risk for anemia in preschoolers.
