The level of observed daily functioning in psychogeriatric nursing home patients may be related to nutrient intake and body weight.
Relationships between nutrient intake, weight and daily functioning were assessed in nursing home residents.
A descriptive, correlational design added by a experimental (repeated measurements) model was used to compare 3-day food records of 90 elderly psycho-geriatric residents filled in by the caretakers every 8 weeks during a period of 6 months. Nutrient intakes and cognitive scores were averaged over the total investigation period and studied separately at week 0, 8, 16 and 24. High and a low nutrient intake groups were compared with respect to daily functioning, which was measured by a Dutch geriatric nursing scale, the Zorg Index geriatrie (ZIG).
Body weight was higher in the high niacin, high vitamin B-6 and high vitamin C intake groups. Unexpectedly, higher vitamin intakes were associated with a worse daily functioning. Results are explained by the fact that patients with a lower cognitive level are more dependent on their caregivers, thereby receiving more help with eating. Consequently, more severely demented patients have a higher intake of energy and nutrients.
In order to optimize the effect of dietary vitamin supplementation in the total severity range of psycho-geriatric residents, caregivers should also pay attention to the eating habits of less dependent patients.
老年精神病护理院患者的日常功能水平可能与营养摄入和体重有关。
评估护理院居民营养摄入、体重与日常功能之间的关系。
采用描述性、相关性设计，并附加实验（重复测量）模型，比较90名老年精神病护理院居民在6个月期间由护理人员每8周填写一次的3天食物记录。在整个调查期间对营养摄入量和认知得分进行平均，并在第0、8、16和24周分别进行研究。就日常功能而言，将高营养摄入组和低营养摄入组进行比较，日常功能通过荷兰老年护理量表——老年护理指数（ZIG）进行测量。
烟酸、维生素B-6和维生素C高摄入量组的体重较高。出乎意料的是，较高的维生素摄入量与较差的日常功能相关。较低认知水平的患者更依赖护理人员，因此在进食方面得到更多帮助，这一事实解释了上述结果。因此，痴呆程度更严重的患者能量和营养摄入量更高。
为了在老年精神病护理院居民的整个严重程度范围内优化膳食维生素补充的效果，护理人员还应关注较少依赖他人的患者的饮食习惯。
