摘要
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。
