摘要
目的了解深圳市外来劳务工膳食结构和营养状况,为开展营养教育和营养改善工作提供科学依据。方法采用分层随机抽样方法抽取工业区集体食堂14所、830名劳务工进行膳食调查;用记账法获得每个集体食堂的调味品的消费量,连续3d 24h回顾法获得每个调查对象各类食物的进食量,与推荐摄入量(Recommended nutrientintakes,RNIs)、2002年广东省居民膳食调查结果进行比较,评价深圳市劳务工的膳食营养状况。结果每标准人日摄入畜禽类、食用油、食盐分别为124.0g、28.1g、7.8g,均高于推荐食物摄入量;水果、鱼虾类、奶类摄入量分别为39.3g、17.4g、23.2g,低于推荐食物摄入量。每标准人日摄入能量2 566.0kcal,占RNIs的107.0%;蛋白质、脂肪、碳水化合物的摄入量分别为75.8g、73.3g、389.0g,提供能量的比例分别为12.0%、26.3%、61.8%。维生素A、硫胺素、核黄素、维生素B6、叶酸和维生素C摄入量分别为514.0μgRE、0.9mg、0.8mg、0.3mg、60.6μg、85.9mg,分别仅占RNIs的64.3%、64.3%、57.1%、25.0%、15.2%、85.9%。钙、镁和锌摄入量分别为418.0mg、315.0mg、12.2mg,分别仅占RNIs的52.3%、90.0%、81.3%。结论深圳市外来劳务工人员膳食结构不尽合理。需加强合理营养、平衡膳食的宣传教育,防止营养相关慢性病发病率持续上升。
