Abstract

Vitamin D deficiency among school-age children is a significant public health issue in Vietnam, especially for children with stunting and at risk of stunting. A cross-sectional study was conducted in 2018 on 384 female students aged 11-13 in 6 communes of Van Chan and Van Yen districts, Yen Bai province to describe vitamin D deficiency. The results indicated the prevalence of Vitamin D deficiency and insufficiency (25(OH)D <50 nmol/L) was 57%; the prevalence of at-risk low, low, and insufficient vitamin D (25(OH)D < 75 nmol/L) was 97.4%; the average of 25(OH)D was 49.2 nmol/L, at the deficiency level. The prevalence of Vitamin D deficiency and insufficiency at Van Yen and Van Chan districts was, respectively, 53.6% and 60.2%. Additionally, the prevalence of vitamin D deficiency and insufficiency was highest at H’mong ethnic (61,9%),  following by Kinh ethnic (56.1%), Tay ethnic (54.5%), and Dao ethnic (53.4%). The results indicated no significant association between the prevalence of vitamin D deficiency and insufficiency and aged groups, communes, districts, and ethnicities (p > 0.05). This study showed the prevalence of vitamin D and insufficiency was significantly high among female students, therefore, It is necessary to have timely intervention solutions to improve vitamin D deficiency for girls 11-13 in Yen Bai as well as in the Northern mountainous region in general.
