To increase the protein intake of older adults, protein enrichment of familiar foods and drinks might be an effective and attractive alternative for oral nutritional supplements (ONS). We performed a pilot study to test whether these products could help institutionalized elderly to reach a protein intake of 1.2 gram per kg body weight per day (g/kg/d).
Intervention study with one treatment group (no control group). Dietary assessment was done before and at the end of a 10-day intervention.
Two care facilities in Gelderland, the Netherlands: a residential care home and a rehabilitation center.
22 elderly subjects (13 women, 9 men; mean age 83.0±9.4 years).
We used a variety of newly developed protein enriched regular foods and drinks, including bread, soups, fruit juices, and instant mashed potatoes.
Dietary intake was assessed on two consecutive days before and at the end of the intervention, using food records filled out by research assistants. Energy and macronutrient intake was calculated using the 2013 Dutch food composition database. Changes in protein intake were evaluated using paired t-tests.
Protein intake increased by 11.8 g/d (P=0.003); from 0.96 to 1.14 g/kg/d (P=0.002). This increase is comparable to protein provided by one standard portion of ONS. The intake of energy and other macronutrients did not change significantly. At the end of the intervention more elderly reached a protein intake level of 1.2 g/kg/d than before (9 vs 4). Protein intake significantly increased during breakfast (+3.7 g) and during the evening (+2.2 g).
Including familiar protein enriched foods and drinks in the menu helped to meet protein recommendations in institutionalized elderly.
为提高老年人的蛋白质摄入量，对常见食物和饮品进行蛋白质强化或许是口服营养补充剂（ONS）的一种有效且有吸引力的替代方式。我们开展了一项试点研究，以测试这些产品能否帮助机构养老的老年人达到每日每千克体重1.2克（g/kg/d）的蛋白质摄入量。
单治疗组的干预研究（无对照组）。在为期10天的干预前后进行饮食评估。
荷兰海尔德兰省的两家护理机构：一家养老院和一家康复中心。
22名老年受试者（13名女性，9名男性；平均年龄83.0±9.4岁）。
我们使用了多种新开发的富含蛋白质的常规食物和饮品，包括面包、汤、果汁和速食土豆泥。
在干预前后连续两天，由研究助理填写食物记录来评估饮食摄入量。使用2013年荷兰食物成分数据库计算能量和常量营养素摄入量。采用配对t检验评估蛋白质摄入量的变化。
蛋白质摄入量增加了11.8克/天（P = 0.003）；从0.96克/千克/天增至1.14克/千克/天（P = 0.002）。这一增加量与一份标准ONS提供的蛋白质相当。能量和其他常量营养素的摄入量没有显著变化。干预结束时，达到1.2克/千克/天蛋白质摄入量水平的老年人比之前更多（9人对4人）。早餐期间（增加3.7克）和晚餐期间（增加2.2克）蛋白质摄入量显著增加。
在菜单中加入常见的富含蛋白质的食物和饮品有助于机构养老的老年人满足蛋白质推荐摄入量。
