Malnutrition and Malnutrition Risk Can Be Associated with Systolic Orthostatic Hypotension in Older Adults

Background: Malnutrition and orthostatic hypotension(OH) are the two important geriatric syndromes, which have similar negative outcomes such as falls. The aim of the study is to detect whether there is any relation between malnutrition and OH. Methods: 862 geriatric patients, who had undergone comprehensive geriatric assessment (CGA), were included in the retrospective study. OH was identified as 20 and/or 10 mmHg dropped for systolic and/or diastolic blood pressures with the active standing test when patients got up from supine to standing position. Nutritional status was checked according to Mini Nutritional Assesment-Short Form(MNA-SF). Results: The mean age of the patients was 74 +/- 8.05, and %66.3 of them were female. The prevalence of malnutrition, malnutrition-risk and OH were detected as 7.7%, 26.9% and 21.2%, respectively. When OH, systolic OH, diastolic OH and control group were compared with CGA parameters and the effects of age and gender were removed, the frequency of falls and Timed-Up and Go Test were higher, activity daily living indexes and TINETTI-Balance scores were lower in systolic OH than without it (p0.05). OH was only higher in malnutrition-risk group than robust (p<0.05). Conclusion: Our findings suggest that not only malnutrition but also malnutrition-risk may be associated with systolic OH, which leads to many negative outcomes in older adults. Because malnutrition/malnutrition risk is preventable and reversible, nutritional status should be checked during the evaluation of OH patients
