Abstract

Objective To analyze the relationship between vitamin D and ferritin nutritional status with physical indicators in primary and secondary school students in the key nutrition monitoring counties of Xinjiang, so as to provide reference for early prevention and intervention of students' nutrition issues. Methods From November to December 2023, 1 071 students aged 6-18 from key nutrition monitoring counties in the Xinjiang Nutrition Improvement Plan area were selected via stratified random sampling for physical and biochemical tests. The U test and Kruskal-Wallis H test were used to compare the differences in physical indicators and the distribution of vitamin D and ferritin levels. Chi-square test was used to compare the prevalence of vitamin D and ferritin deficiencies among different groups of primary and secondary school students. Pearson correlation was used to analyze the relationship between the nutritional levels of vitamin D and ferritin and physical indicators. Results The median vitamin D level was 14.7 (10.7, 19.0)ng/mL, with deficiency and insufficiency rates of 30.8% and 37.4% among primary and secondary school students in the key nutrition monitoring counties of Xinjiang Nutrition Improvement Plan area. Ferritin levels were 57.4 (37.7, 83.9)μg/L, with a deficiency rate of 5.7%. Males, primary school students, and rural residents had higher vitamin D and ferritin levels than females, secondary school students, and urban residents (U=-11.35, -6.88, -4.52; -3.94, -9.17, -5.23, P < 0.05). Vitamin D deficiency was more prevalent in females, secondary school students, and urban students (χ²=97.52, 49.01, 21.89, P < 0.05), while ferritin deficiency was higher in primary school students and urban areas (χ²=34.11, 5.63, P < 0.05). Significant differences in body mass index (BMI) and waist circumstance (WC) were observed across vitamin D/ferritin statuses (U/H=35.47, 22.82; -4.19, -5.36, P < 0.05). Vitamin D and ferritin levels negatively correlated with age, BMI, and WC but positively with waist-to-height ratio (WHtR) (r=-0.31, -0.19, -0.19, 0.20; -0.32, -0.13, -0.21, 0.08, P < 0.05). Conclusions Vitamin D and ferritin levels in primary and secondary school students in key nutritional monitoring counties in Xinjiang are correlated with age, BMI, WC and WHtR, and there are nutrient deficiencies. Targeted measures are recommended to improve nutritional status and physical health.
