To investigate the malnutrition prevalence in Dutch care home residents with dementia over the years. Secondly, to examine the relationship of malnutrition and dementia and the role of care dependency and co-morbidity within this relationship.
This study is a secondary analysis of data of the annual independent Dutch National Prevalence Measurement of Care Problems of Maastricht University. The design involves a cross-sectional, multicenter point prevalence measurement.
Care homes.
75399 residents older than 65 years (4523 resident with dementia) participated over 5 years (2006-2010). Sixty organizations measured 4 times, 31 organizations 3 times, 68 organizations 2 times, 511 organizations 1 time.
A standardized questionnaire was used to register amongst others data of weight, height, nutritional intake, undesired weight loss, comorbidity, dementia, and care dependency.
The study was able to show that there is a significant decline in malnutrition prevalence in the group of non-demented residents over the years (Non-demented group p <0.001). The prevalence of malnutrition in the demented group showed no significant reduction over the years. GEE analysis showed that malnutrition and dementia are related and that care dependency and age are important influencing factors in this relation.
The results show that compared to the non-demented residents, the prevalence of malnutrition does not decline in demented care home residents over the years. Moreover, the findings of this study stress that malnutrition and dementia are related, while care dependency and age are confounding factors in this relationship.
调查多年来荷兰养老院痴呆症患者的营养不良患病率。其次，研究营养不良与痴呆症的关系，以及在这种关系中护理依赖和合并症的作用。
本研究是对马斯特里赫特大学荷兰国家独立年度护理问题患病率测量数据的二次分析。该设计涉及横断面、多中心时点患病率测量。
养老院。
超过 5 年（2006-2010 年），有 75399 名 65 岁以上居民（4523 名痴呆症患者）参与。60 个组织测量了 4 次，31 个组织测量了 3 次，68 个组织测量了 2 次，511 个组织测量了 1 次。
使用标准化问卷登记了体重、身高、营养摄入、非预期体重减轻、合并症、痴呆症和护理依赖等数据。
研究表明，非痴呆组居民的营养不良患病率在多年间呈显著下降（非痴呆组 p<0.001）。痴呆组的营养不良患病率多年间无显著下降。广义估计方程分析表明，营养不良和痴呆症之间存在关联，而护理依赖和年龄是这种关系中的重要影响因素。
结果表明，与非痴呆居民相比，痴呆症养老院居民的营养不良患病率多年间并未下降。此外，本研究的发现强调了营养不良和痴呆症之间存在关联，而护理依赖和年龄是这种关系中的混杂因素。
