RESUMO
To study the effect of multi-micronutrients supplementation on nutritional status of children, 220 students aged 8-12 years were observed for 6 months. A half of them were given the supplements, another half placebo. The results showed that in comparison with the placebo, the supplemented children had a higher urine excretion of vitamin B2 and vitamin C after loading; a higher concentration of serum 25-OH-D3, a high content of hydroxy-proline and hydroxy-proline/creatinine ratio in fast urine, and a higher bone mineral content and bone mass density of the mid-ulna. The supplemented children performed significantly better than the placebo in reading speed, learning capacity and arithmetic examinations. It is concluded that micronutrients supplementation played a notable rule in resulting better nutritional status and learning ability of school children.

In order to investigate the effect of vitamins-minerals supplementation on the nutritional status of Chinese women, 252 villagers aged 20-50 years old were selected as the participants in the study in Longli County, Guizhou Province. Within Twenty two weeks, half of the participants received the supplements and half had placebo. The results showed that in comparison with the control, the women with supplementation represented a higher urine excretion of vitamin B1 and B2 after a loading dosage and, a higher concentration of serum iron and zinc and a lower prevalence of anemia. They kept their facial moisture and grease better than those of the controls. They also felt better in sleeping, having appetite, and doing physical activities. The results indicated that the supplementation of vitamins-minerals might improve the nutritional status of rural Chinese women.
