摘要
目的了解山东省青岛市农村老年人群的膳食营养状况。方法采用24h膳食回顾法调查农村500名老年人的食物消费、营养素摄入和膳食构成的情况。结果男、女老年人平均每人日摄入能量分别为推荐摄入量(RNI)的91.8%和85.2%,蛋白质摄入量达到RNI的91.4%和87.1%,维生素A的摄入量为RNI的64.0%和583%,维生素C的摄入量为RNI的63.9%和56.2%,维生素E的摄入量为适宜摄入量(AI)的60.7%和53.9%;老年人膳食能量的60%以上来自植物性食品,其中谷类食品占56.5%;蛋白质的食物来源中,谷类食品占39.7%,动物性食物占38.7%;男、女老年人膳食中碳水化合物提供的能量分别占总能量的66.2%和69.0%,脂肪占17.5%和15.8%,蛋白质占16.3%和15.2%。结论老年人膳食中蛋类和水产品的摄入充足;水果、蔬菜、谷类的摄入量较低;摄入的能量基本能够满足机体的需要,蛋白质的食物来源较好;维生素E、C和A等抗氧化维生素摄入不足;三大营养素的供能比中脂肪提供的能量偏低。
Objective To know the nutrition status of the rural elderly by a diet survey. Methods A 24hr diet recall in 500 elderly people was used to survey and analyze total quantity of food consumption, nutrients intake and the constitution of diet. Results The average daily intake of energy of the investigated males and females was 91.8% and 85.20% of RNI （Recommended Nutrient Intake）, the intake of protein was 91.4% and 87.1% of RNI, the retinol was 64.0% and 58.3% of RNI and the Vit C was 63.9 % and 56.2 % of RNI, respectively. The intake of Vit E was 60.7 % and 53.9 % of AI（Ade- quate Intake）, respectively. More than 60 % of the source of energy was from vegetation, in which 56.5 % was grains. 39.7% of the protein was from grain, and 38.7% from animal food. For male and female subjects, 66.2% and 69.7% of the total energy was provided by carbohydrate, 17.5 % and 15.8 % by fat, and 16.3 % and 15.2 % by protein, raspectively. Conclusion The intakes of eggs and aquatic food were enough in the diet of the elderly people, while the intakes of fruits, vegetables and grains were lower. The intake of protein was ideal, but the intakes of Vit E, Vit C and retinol were insufficient. The ratio of energy provided by fat was lower than by carbohydrate or protein.
