对贵州省５个中、下经济水平县（市）农村２０个乡（镇）的４３４５名０～６岁儿童进行核黄素缺乏、血红蛋白与体格发育以及１０％的３～５岁儿童膳食调查的结果表明：膳食构成植物性食物来源摄入量占９３．８％，核黄素摄入量仅占供给量推荐标准（ＲＤＡ）的３１．６％，铁摄入量超过ＲＤＡ达１１０％。核黄素缺乏率均达１４．４％，贫血率均达３９．１％，身材矮小率高达４３．３％，低体重儿为２６．６％（Ｆ值Ｐ＜０．０１，ｑ值Ｐ＜０．０１）。提示由于喂养问题，核黄素缺乏与贫血、生长发育有一定的关联性。
Riboflavin deficiency, hemoglobin and physical development, and 10% of children aged 3-5 were surveyed on 4345 children aged 0-6 in 20 rural (township) rural areas of five middle and lower economic levels in Guizhou Province The results showed that dietary intake of plant-based food accounted for 93.8%, riboflavin intake accounted for only 31.6% of the recommended supply standard (RDA), and iron intake exceeded RDA by 110%. Riboflavin deficiency rate reached 14.4%, anemia rate reached 39.1%, short stature rate as high as 43.3%, low birth weight children was 26.6% (F value P <0.01, q value P <0.01). Tip Due to feeding problems, riboflavin deficiency and anemia, growth and development have a certain relevance.
