摘要

The objective of the study was to assess the prevalence of sub clinical vitamin A deficiency and anemia in Vietnamese children. For this, a cross-sectional survey was conducted in 40 villages (clusters) of four ecological regions in Vietnam during Apr-May 2001. In total 1657 children less than 5 years old were included by a cluster random sampling method. The prevalence of sub clinical vitamin A deficiency (serum retinol ＜0.70 μmol/L) was 12.0% and the prevalence of anemia (hemoglobin ＜110g/L) was 28.4 %. In the children under 6 months the prevalence of sub clinical vitamin A deficiency was 35.1 % whereas the prevalence of anemia in this group was as high as 61.7%. The prevalence of children with both sub clinical vitamin A deficiency and anemia was 6.1%. Sub clinical vitamin A deficiency and anemia prevalence differed significantly across the regions, with highest prevalence in the Northern Mountainous areas for vitamin A deficiency and in the Northern Mountainous area and Mekong River Delta for anemia. It is concluded that sub clinical vitamin A deficiency and anemia are still important public health problems in Vietnam. Sustainable strategies for combating vitamin A deficiency and nutritional anemia are needed and should concentrate on target groups, especially infants and malnourished children in high risk regions.
