Determining malnutrition and associated variables in the elderly.
A cross-sectional study was conducted among elderly people vaccinated against influenza in order to evaluate their nutritional status. Nutritional assessment was performed with the Mini Nutritional Assessment. To verify association of studied variables with the outcome, odds ratios was estimated using multiple logistic regression.
A total of 236 elderly patients were recruited. The Mini Nutritional Assessment identified three patients (1.3%) with malnutrition and 59 (25%) at risk of malnutrition. Factors with a positive association to the outcome were psychological stress or acute disease in the past three months, weight loss (< 3 kg) during the last three months and sores or skin ulcers. On the other hand, consuming two or more servings of fruits or vegetables daily, eating meat, fish or poultry every day and drinking more than three cups of fluids per day were negatively associated to malnutrition and risk of malnutrition.
The low prevalence of malnutrition found in this study may be due to the study sample of elderly individuals in good health. Some factors related to a recent health problem (psychological stress or acute disease) seem to be positively associated while regular consumption of fluids and certain foods seem to be negatively associated with malnutrition.
确定老年人的营养不良及相关变量。
对接种流感疫苗的老年人进行横断面研究,以评估他们的营养状况。采用微型营养评定法进行营养评估。为验证研究变量与结果之间的关联,使用多元逻辑回归估计比值比。
共招募了236名老年患者。微型营养评定法确定了3名(1.3%)营养不良患者和59名(25%)有营养不良风险的患者。与结果呈正相关的因素包括过去三个月的心理压力或急性疾病、过去三个月体重减轻(<3千克)以及溃疡或皮肤溃疡。另一方面,每天食用两份或更多份水果或蔬菜、每天吃肉、鱼或家禽以及每天饮用三杯以上液体与营养不良及营养不良风险呈负相关。
本研究中发现的营养不良低患病率可能归因于健康状况良好的老年研究样本。一些与近期健康问题相关的因素(心理压力或急性疾病)似乎呈正相关,而定期饮用液体和食用某些食物似乎与营养不良呈负相关。
