深圳市学龄前儿童硫胺素,核黄素及铁的营养状况

深圳市学龄前儿童缺铁性贫血检出率为10．6％，1～3岁年龄组（13．5％）高于4～6岁年龄组（9．72％）；男童（14．4％）明显高于女童（5．3％）．提示儿童的缺铁性贫血与性别有关。学龄前儿童中硫胺素缺乏者占20．4％．1～3岁年龄组（30．9％）高于4～6岁年龄组（17．2％）；核黄素不足者占13．2％，1～3岁年龄组（25．5％）高于4～6岁年龄组（9．4％）．核黄素不足儿童的缺铁性贫血检出率（16．1％）高于核黄素营养正常儿童（9．3％）硫胺素缺乏儿童的核黄素不足检出率（31．3％）明显高于硫胺素营养正常的儿童（8．6％），提示核黄素不足与硫胺素营养状况有关。

Thiamine, Riboflavin and Iron Nutriture of Shenzhen Preschool Children

The investigation on nutritional status of Shenzhen preschool children revealed that children with iron deficient anemia(IDA), thiamine deficlency(TD) and riboflavin insufficiency(RI ) accounted for 10. 6 %, 20. 4 % and 13.2 % respectively. IDA occurred more frequently in children ages 1~ 3 than in children ages 4 ~ 6(13. 5 % vs 9.7% ), as did TD(30. 9% vs 17.2% ) and RI (25. 5% vs 9.4% ). Boys were more likely to be at risk for IDA(14.4%) than girls (5. 3% ). IDA was more common among riboflavin insufficient children than among riboflavin normal children (16.1% vs 9. 3% ), The proportion of riboflavin insufficient children was greater in thiamine deficient children than in thiamine normal children. The findings suggest that RI is highly correlated with thiamine nutriture.
