调查钢铁厂高温作业工人的膳食摄入情况及体内营养水平，为高温作业工人的营养状况的改善提供依据.采用整群随机抽样方法，选取唐山市某钢铁厂高温作业工人226 人，按高温作业等级分为Ⅲ级和Ⅳ级两组，进行一般状况、体格检查、膳食状况调查、体内营养素水平检测.钢铁高温作业工人存在营养缺乏和失衡的问题，核黄素、维生素A、钙的摄入量分别占推荐摄入量的85.7％、95.6％、64.6％，低于一般人群推荐摄入量；抗坏血酸、核黄素、维生素A、钾、钙分别占高温建议摄入量的56.7～78.5％、52.2～70.6％、51.0％、76.6～89.1％、64.6％，低于高温建议摄入量，为摄入不足；抗坏血酸、核黄素、维生素A、钾、钠的体内不足和缺乏率为95.3％、30.9％、41.7％、53.3％、39.4％，为严重不足和缺乏.其中Ⅳ级高温作业工人抗坏血酸、核黄素、钾、钠、钙、铁、锌、铜的体内水平低于Ⅲ级工人，且差异具有统计学意义(p＜0.01)；Ⅳ级高温作业工人核黄素、钾、钠、钙、铁、锌的体内不足和缺乏率高于Ⅲ级工人，且差异具有统计学意义(p＜0.01).唐山市钢铁高温作业工人膳食营养存在营养缺乏和失衡的问题，且体内营养素水平普遍存在不足或缺乏的问题.
