The reasons of anorexia of ageing are multiple and not well-known. One of them is loss of appetite. We aimed to know the prevalence of self-reported appetite-loss in the elderly and its relationship with nutritional status, muscle strength and functional capacity.
A population based cross-sectional study in which 236 non-institutionalized subjects over 70 years were randomly selected. Hand grip, functional capacity and nutritional status were assessed and a specific questionnaire was administered to assess appetite. Anorexia or loss of appetite was considered when subjects declared none or low usual appetite both in breakfast and lunch time.
A 30.0% global prevalence of anorexia was observed (37.1% in females and 17.9% in males; p = 0.001). Loss of appetite was related to higher risk of malnutrition (41% in anorexic vs 27% in non-anorexic; p = 0.039), lower muscular strength and poorer functional capacity.
Loss of appetite in the elderly has a high prevalence and must alert about frailty.
衰老导致厌食的原因多种多样且尚不明确。其中一个原因是食欲减退。我们旨在了解老年人自我报告的食欲减退的患病率及其与营养状况、肌肉力量和功能能力的关系。
一项基于人群的横断面研究，随机选取了236名70岁以上的非机构化受试者。评估了握力、功能能力和营养状况，并使用一份特定问卷来评估食欲。当受试者宣称早餐和午餐时均无食欲或食欲较低时，即视为厌食或食欲减退。
观察到厌食的总体患病率为30.0%（女性为37.1%，男性为17.9%；p = 0.001）。食欲减退与营养不良风险较高（厌食者中为41%，非厌食者中为27%；p = 0.039）、肌肉力量较低和功能能力较差有关。
老年人食欲减退的患病率较高，必须对虚弱状况予以警惕。
