广州市外来人口膳食行为,营养知识及营养状况调查

抽样来广州打工6月以上人员274名，以问卷方式调查其营养知识和膳食行为，结果分别进行评分，完全正确的以10分计；以眼部、皮肤及口腔的营养缺乏体征作为判断营养缺乏的标准。结果表明，营养知识的平均得分为443±1．40分，膳食行为的平均得分为4．81±1．46分，后较低水平。营养知识得分越高者，正确膳食行为得分也越高，相关显著（r＝0．155，P＜0．05）。而学历高低与膳食行为没有相关性；此外，女性膳食行为得分高于男性（P＜001）。此外，被调查人员有不同程度营养素缺乏的临床体征，如皮肤粗糙发生率为76.6％，角膜干燥为1．82％，牙龈出血最多发，为20．1％。此提示外来人口的营养不良是值得注意的问题，同时亦表明营养知识普及的紧迫性和重要性。
