Abstract: In this study, we assessed the hemoglobin levels and anemia status of Chinese children and adolescents from the Chinese National Nutrition and Health Survey (CNNHS) in 2010–2012 and analyzed the factors associated with anemia. The hemoglobin concentration and prevalence of anemia for children and adolescents aged 6–17 years from both CNNHS 2010–2012 and CNNHS 2002 were analyzed. Multi-variable logistic regression analysis was used to assess the factors associated with anemia. The mean hemoglobin concentration increased among Chinese children and adolescents, from 135.2 ± 13.9g/L in CNNHS 2002 to 141.2 ± 15.8 g/L in CNNHS 2010–2012, with the prevalence of anemia decreasing from 12.6% to 6.6% ( p < 0.0001). Anemia was specifically related to girls ( p < 0.0001); children aged 6–8 years ( p = 0.0175), 12–14 years ( p = 0.0007), and 15–17 years ( p < 0.0001); ordinary rural areas ( p = 0.0009) and poor rural areas ( p < 0.0001);spring ( p < 0.0001), autumn ( p < 0.0001), and winter ( p < 0.0001);underweight individuals ( p < 0.0001); and an annual average income per capita of less than 20,000 RMB ( p < 0.0001).The prevalence of anemia in Chinese children and adolescents has improved significantly in comparison to 10 years prior; however, it remains a public health problem in this population. Further research is required to understand the determinants of iron status, which could then lead to strategies to alleviate iron deficiency for Chinese children and adolescents, especially for girls, those living in rural areas, underweight individuals, and those with a low family income.
