摘　　要：目的比较营养干预前后老年人群的饮食行为以及抗氧化酶的活性以及脂质过氧化损伤指标的变化,探讨营养宣教能否通过饮食行为改变而影响机体抗氧化功能。方法随机抽取某市227名老年人实施各种措施的综合营养干预,包括宣教和营养素补充。干预前后进行饮食行为等调查,测定血清抗氧化指标。结果干预前老年人的营养知识水平比较低,老年人的营养知识水平得到了提高,但干预后抗氧化指标没有变化。结论本次营养宣教对老年机体饮食行为有促进作用,但对机体抗氧化功能影响不大。Objective We compared the antioxidant enzyme activity of lipid peroxidation before and after the nutrition education in order to investigate whether the changes of the dietary behavior affected body anti-oxidation function.Methods 227 elderly people in a city were randomly selected to implement a comprehensive nutrition education measure before and after eating behavior missionary survey and measure the serum antioxidant index.Results The nutritional knowledge level of elderly people was relatively low before the nutrition education.After the intervention antioxidant index had not changed,but the elderly increased nutritional knowledge.Conclusion Nutrition education can promote the healthy dietary behaviors for the elderly,but had little effect on antioxidant function.
