Subjects and methods: A cross-sectional study was performed on 375 nine years old children who were not puberty in 3 primary schools in Haiduong city. Subjects were measured body weight, height and examined for vitamin D deficiency based on serum 25(OH)D concentration. Results: Prevalence of underweight, stunting, and wasting was , and , respectively. Prevalence of overweight and obesity was . There was no significant difference about prevalence of underweight, stunting, wasting and overweight-obesity between boys and girls. Overall prevalence of vitamin D deficiency was (in girls , in boys ). Prevalence of vitamin D insufficiency was , higher in girls () compared to boys (), p +2SD. * Classification of vitamin D serum status: Assessement of vitamin D deficiency was based on serum 25(OH)D concentration. Vitamin D was deficient when 25(OH)D concentration Weight (kg) ± 5,4 ± > Height (cm) ± ± > WAZ (Zsore) ± ± > HAZ (Zscore) ± ± > BAZ (Zsore) ± ± > Study results showed that there was no significant difference about anthropometric characteristics between boys and girls: age, weight, height, Zscore WAZ, Zscore HAZ, Zscore BAZ.
