Rationale: Malnutrition is a common problem in older adults, particularly those receiving home care services. Although its association with adverse outcomes is well known in hospitalized older adults, the prognostic significance of malnutrition risk in home-cared octogenarians remains insufficiently explored. This study examined whether baseline malnutrition risk predicts all-cause mortality in this frail group.
Methods: This cohort study included patients aged ≥80 years followed by a geriatric home-care outpatient clinic. A comprehensive geriatric assessment was performed.Nutritional status was assessed using the Mini Nutritional Assessment Short Form.
Results: A total of 238 patients over 80 years old were included (median age 86.1 (IQR: 83.0–90.3) years; 63.6% female). The median (IQR) follow-up duration was 15.7 (11.5-27.6) months. Overall mortality rate was 24.7% Overall mean ± SE survival time was 27.3 ±0.78 months. Patients who died were more older, frail, dependent in activities of daily living, more likely to have dementia, cerebrovascular diasese and malnutrition risk (MNA-sf<12). In the Kaplan Meier survival analyses the mean survival time for patients with malnutrition risk was significantly lower. (p=0.001). In the cox regression analyses, malnutrition risk at the baseline assessment was significantly related to 2.6 fold increased all-cause mortality regardless of age, sex, dementia, cerebrovascular disease and frailty. (HR (95%CI: 2.64 (1.34 – 5.20) p =0.005))

Conclusion: In home-cared octogenarians, baseline malnutrition risk assessed by MNA-SF was independently associated with a 2.6-fold increase in all-cause mortality, even after adjusting for age, frailty, dementia, and cerebrovascular disease. Nutritional screening at the time of geriatric assessment may help identify patients at heightened mortality risk within this specific cohort.
