Abstract

Abstract

Objective To investigate the current status of iron deficiency(ID) and anemia among students in the nutrition improvement programme areas of Hunan Province in 2023, and to explore the the potential factors. Methods During the period October-December 2023, a total of 4 652 students were included in this study using a multistage stratified whole cluster random sampling method, out of which 1 108 students were tested for serum ferritin (SF). Logistic regression was used to analyze the factors influencing anemia, ID and iron deficiency anemia (IDA). Results The average hemoglobin (Hb) level of students in the 2023 nutrition improvement program area of Hunan Province was (131.49±12.92) g/L, and the prevalence of anemia was 11.54% (95% CI: 10.62-12.46); the average SF level was 53.47 (34.53, 81.35) μg/L, and the prevalence of ID and IDA was 5.23% (95% CI: 3.92-6.55) and 1.35% (95% CI: 0.67-2.04), respectively. Multifactorial analysis showed that girls (OR=1.482, 95% CI: 1.125-1.778) and students whose school location was a township or village (OR=1.420, 95% CI: 1.138-1.771) had a higher risk of anemia, while students aged 10-15 years had a lower risk of anemia compared to those aged 6-10 years (OR=0.806, 95% CI: 0.656-0.992). In the analysis of ID and IDA, girls and junior high school students had a higher risk of the diseases (ID: OR_female=3.523, 95% CI: 1.898-6.542, OR_{junior high school}=4.120, 95% CI: 2.251-7.541; IDA: OR_female=6.933, 95% CI: 1.551-130.984, OR_{junior high school}=8.837, 95% CI: 1.979-39.462). Conclusions Nutrition Improvement Program areas in Hunan Province still need to further increase the prevention and control of ID and IDA among students, strengthen nutritional monitoring, pay attention to the health of key populations, and give targeted dietary guidance and health education.
