采用整群随机抽样方法，对贵阳市524名40～60岁的中年知识分子进行膳食营养状况调查。结果表明：受试者的热能、维生素A、维生素B2、Ca等多种营养素摄入不足，每人每日平均摄入热量占供给标准的81．66％，而Ca的摄入仅达59．38％RDA。蛋白质、脂肪和碳水化合物的生热比分别为14．71％，26．79％，58．50％，优质蛋白占总蛋白的50．02％；动物脂肪占总脂肪的51．11％；膳食铁的72．54％来源于植物铁；计算体质指数(BMI)表明肥胖发生率较全国低；生化检验显示男性贫血患病率为8．3％，女性为21．9％。由此可见，贵阳市中年知识分子某些营养素的摄入还不足，膳食结构亦不合理，应进行营养指导提出改进措施，以改善他们的营养状况和健康状况。

The results showed that intake of energy, protein, VA, VB2, calcium were 81.66%, 99.57%,75.55%,70.83%, 59.38% of Chinese RDA respectively. These in dicated the intakes of energy, VA, VB2, Ca were insufficient. Protein provided 14.71%, fat 26.79%, carbohydrate 58.5% of total energy in take. The consumption of cereal and vegetabls was obvious inadequate. 72.54% of iron originated from vegetal sources. The incidence of anemia was 8.3% in men and 21.9% in wonen.
