目的了解辽宁省≥50岁居民营养素摄入水平,为政府制定相应社会发展政策提供依据。方法在2009年辽宁省居民膳食营养与健康调查数据中选取536名≥50岁居民资料进行分析。结果辽宁省≥50岁居民每人每天摄入的能量平均为8 510.05 kJ(2 040.78 kCal),占推荐摄入量(RNI)的92.76%,从食物中获得的能量基本得到满足,蛋白质摄入量平均为66.83 g,占推荐摄入量的95.47%,脂肪、碳水化合物、膳食纤维的摄入量分别为68.35、274.60、13.01 g;≥50岁居民维生素A、B1、B2平均摄入水平严重不足,分别为557.94μg视黄醇当量、0.95 mg、0.83 mg,仅占RNI的74.39%、73.08%、59.29%,钠、铁、磷、锰的摄入量分别为4 808.03、21.27、984.14、4.14 mg,远高于适宜摄入量(AI),分别是AI的2.19、1.42、1.41、1.72倍;钙的摄入量为454.89 mg,远低于AI,仅占AI的45.49%。结论辽宁省≥50岁居民营养素摄入不平衡,应加强营养知识的宣传教育,引导居民合理膳食,以有效预防与营养有关慢性病的发生。

Nutrition intake among middle-aged and elderly residents in Liaoning province, 2009

Objective To assess nutrition intake among middle-aged and elderly residents in Liaoning province and to provide evidence for making social development stratigies by the government.Methods The data of 536 residents at or above the age of 50 years were collected from the data of the Survey on Dietary Nutrition and Health in Residents of Liaoning Province,2009 and analysed.Results Among the residents,the standardized average daily energy intake was 8 510.05 kJ(2 040.78 kCal).The energy intake was 95.47% of recommended nutrient intake(RNI) and mainly from food.The daily average intake of protein,fat,carbonhydrate,and dietary fiber was 66.83 g(95.47% of RNI),68.35 g,274.60 g,and 13.01 g,respectively.There were seriously insufficient average intakes of vitamin A(557.94 μg retinol equiavlent,74.39% of RNI),vitamin B1(0.95 mg,74.39% of RNI),and vitamin B2(0.83 mg,59.29% of RNI).There were higher average daily intakes than the adequake intake(AI) for sodium(4808.03 mg,2.19 times of AI),iron(21.27 mg,1.42 times of AI),phosphorus(984.14 mg,1.41 times of AI),and maganese(4.14 mg,1.72 times of AI),but the average daily intake of calcium was only 454.89 mg(45.49% of AI).Conclusion There was an imbalance in average daily nutrition intake among the residents at or above the age of 50 years in Liaoning province and health education on reasonable diet needs to be promoted to prevent malnutrition-related diseases among the residents.
