100名老年妇女和男子的营养状况进行了评估，他们的膳食营养素摄入量和选择的生化指标。钙、维生素A和硫胺素是最有可能缺乏的膳食营养素，尤其是女性。27名受试者服用的营养补充剂一般不适当，而且经常过量。41%的人血清蛋白浓度低。90%的受试者的红细胞压积、血红蛋白、血清铁和抗坏血酸、血浆维生素A和胡萝卜素值在可接受范围内。除血红蛋白与日粮铁、血清抗坏血酸与日粮抗坏血酸相关外，其他生化指标与日粮营养素无显著相关性。在20人的子样本中，饮食和血清叶酸值都很低。生活在退休社区的20名受试者每天提供一顿大餐，比那些完全独立但生化值相似的人消耗更少的食物。
The nutritional status of 100 elderly women and men was evaluated in terms of their dietary nutrient intakes and selected biochemical measurements. Calcium, vitamin A, and thiamin were the dietary nutrients most likely to be deficient, especially with women. Nutrient supplements, taken by 27 subjects, were generally inappropriate and frequently excessive. Forty-one percent of the group had low serum protein concentrations. Values for hematocrit, hemoglobin, serum iron and ascorbic acid, plasma vitamin A and carotene were in acceptable ranges for 90% of the subjects. Biochemical values were not significantly correlated with dietary nutrients except for hemoglobin with dietary iron and serum ascorbic acid with dietary ascorbic acid. In a subsample of 20 persons, both dietary and serum folate values were low. Twenty subjects who lived in a retirement community that provided one major meal daily consumed less food than those who were completely independent but had similar biochemical values.
