Abstract: Anaemia is a public health problem that can lead to various harmful effects on physical and neurodevelopment in infants and young children (IYC). This study aimed to investigate trends of anaemia and haemoglobin concentration among 6- to 23-month-old Chinese IYC from 2016 to 2018. We used data from the China Nutrition Improvement Project on Children in Poor Areas (CNIPCPA), conducted in 142 national-level poor counties of 20 provinces, autonomous regions, and municipalities from 2016 to 2018. Our study included 103,621 6- to 23-month-old IYC selected by a stratified multistage cluster sampling design. There were 26,303, 33,443, and 43,875 IYC in the survey in 2016, 2017, and 2018, respectively. The overall prevalence of anaemia was 27.0% in the three years. The prevalence of anaemia was 28.0%, 27.2%, and 26.2%, and the mean haemoglobin (Hb) was 11.82, 11.81, and 11.88 g/dL in 2016, 2017, and 2018, respectively. The prevalence of anaemia was highest in 6- to 11-month-olds, and declined with age. There was a gap in the education level between parents. However, the percentage of education improved in the rural areas of China. The prevalence of anaemia decreased significantly in the three years, which shows that prevention and control actions achieved the initial results.
