老年人是最大的人口群体，他们面临着饮食不足和营养不良的极大风险。老龄化与许多生理功能的下降有关，这些功能可能影响营养状况，包括瘦体重减少和由此导致的基础代谢率下降、消化液的胃分泌减少和口腔变化、感觉功能缺陷、液体和电解质调节变化以及慢性疾病。药物治疗、住院治疗和其他社会决定因素也会造成营养不足。老年人的营养状况是生活质量、发病率和死亡率的一个重要决定因素。这篇评论批判性地审查了导致老年人营养不良的因素，并考虑了营养不良的后果。
The older population is the single largest demographic group at disproportionate risk of inadequate diet and malnutrition. Ageing is associated with a decline in a number of physiological functions that can impact nutritional status, including reduced lean body mass and a resultant decrease in basal metabolic rate, decreased gastric secretion of digestive juices and changes in the oral cavity, sensory function deficits, changes in fluid and electrolyte regulation and chronic illness. Medication, hospitalization and other social determinants also can contribute to nutritional inadequacy. The nutritional status of older people is an important determinant of quality of life, morbidity and mortality. This review critically examines the factors that contribute to the development of poor nutritional status in older people and considers the consequences of malnutrition.
