Daily intakes of protein and energy were estimated in a group of 417 apparently healthy elderly Chinese subjects aged 60 years and over, living independently in the community. The mean protein intake was 1.2 g/kg body weight, well above the WHO/FAO/UNU recommendation of 0.8 g/kg, and comparable to intakes of elderly Americans and Britons. Plasma total protein, albumin, prealbumin, retinol binding protein and transferrin concentrations were also measured. No age- or sex-related differences were found and the values were comparable to published values for elderly Caucasians. Plasma prealbumin and retinol binding protein concentrations correlated with protein intake and with arm muscle area. Protein nutritional status appears adequate for elderly Chinese living in the community.
对一组417名60岁及以上、独立生活在社区的明显健康的中国老年人估计了蛋白质和能量的每日摄入量。平均蛋白质摄入量为1.2克/千克体重，远高于世界卫生组织/联合国粮农组织/联合国大学推荐的0.8克/千克，与美国和英国老年人的摄入量相当。还测量了血浆总蛋白、白蛋白、前白蛋白、视黄醇结合蛋白和转铁蛋白浓度。未发现与年龄或性别相关的差异，这些值与已发表的老年白种人的值相当。血浆前白蛋白和视黄醇结合蛋白浓度与蛋白质摄入量和手臂肌肉面积相关。对于生活在社区中的中国老年人来说，蛋白质营养状况似乎是充足的。
