Due to the multifactorial nature of falls in the elderly population, it is difficult to determine causal relationships for risk factors for falls. In some cases, other risk factors may play a role. For example, the association between poor nutrition status and falls has not been studied extensively. The association of commonly demonstrated nutritional deficiencies in the elderly with factors such as balance, gait, and mobility may lead to new insights into causes of falls in the elderly not previously established. In this article, we review how malnutrition can be a risk factor for falls, how falls can induce malnutrition, and the possible relationship between mobility and nutrition in the elderly.
