Aim This systematic review and meta-analysis aims to characterize the nutritional status of geriatric rehabilitation patients and its association with functional parameters. Findings Malnutrition is prevalent in a relevant percentage of geriatric rehabilitation patients, whereas body mass index (BMI) is in the normal to overweight range. Furthermore, data suggest that protein and energy intake is reduced and vitamin D deficiency is prevalent in this population. Decreased physical function is associated with malnutrition according to Mini-Nutritional Assessment (MNA) and MNA short form, whereas BMI did not show any clear association. Message Nutritional status is reduced in a relevant percentage of geriatric rehabilitation patients and associated with decreased physical function which emphasizes the need for screening and targeted interventions.
Geriatric patients undergoing a rehabilitation program outside inpatient, ambulatory, or hospitalization care need an adequate supply of energy and nutrients. Malnutrition must be avoided, ideally before starting rehabilitation. Nutritional interventions are most beneficial in combination with exercise training.
In later life a high body mass index (BMI) is associated with the lowest age-related mortality rate. The BMI range used by the World Health Organization (WHO) to classify overweight, a BMI of 25-30 kg/m, can be regarded as normal weight in old age; nevertheless, obesity is associated with an increased risk of disability and of a deterioration in physical functionality, particularly among older age groups. This relationship to obesity has also been established for frailty. For this reason, a reduction in weight may be appropriate under functional aspects if BMI values exceed 30 kg/m; however, such a decision cannot be made on the basis of an individual BMI alone. The functional status, body composition, comorbidities and, in particular the life perspectives of the patient should also be taken into consideration. If weight loss is intended, it must always be performed under strict medical supervision involving optimized protein intake, a carefully calculated moderate reduction in calories and adequate physical training. In the case of chronically ill elderly patients, weight reduction is not usually appropriate. Restrictive diets of any kind should principally be critically viewed in old age because even temporary inadequate energy intake may lead to accelerated deterioration of muscle and bone structure.
The obesity pandemic has reached old age but the effect of obesity on functional recovery in geriatric rehabilitation patients has not been investigated to date. In this prospective cohort study, patients admitted into geriatric rehabilitation were consecutively included between September 2015 and September 2016, aged ≥ 70 years. Individual activities of daily living were documented by the Barthel index (BI, 0-100 points). Obesity was assessed by the measurement of body mass index (BMI, kg/m²), waist circumference (WC, cm) and percentage of body fat mass (%FM) based on triceps’ skinfold thickness at admission (t1), discharge (t2) and six months after discharge (t3). A total of 122 patients were included in the analysis. Prevalence of obesity according to BMI, WC and %FM was 33.6%, 83.6% and 71.3% respectively. Patients with a high WC and patients with a high BMI had lower BI values at t1, t2, t3 and the improvement in BI (t1 - t2, t2 - t3) was lower than in those with low WC and low BMI, but without statistical significance. In multiple regression analysis, BMI, WC and %FM were not associated with BI at t3 and improvement of BI (t2 - t3). Obesity was highly prevalent in geriatric rehabilitation patients, but it was not associated with BI during the 6-month follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
