ABSTRACT
OBJECTIVES:
Malnutrition, particularly protein insufficiency, is common in institutionalised older adults and increases morbidity, mortality, and costs. We aimed to determine whether 12 months supplementation using high-protein foods (milk, cheese, yoghurt) prevents malnutrition in older adults.DESIGN:
Cluster randomised control study.SETTING:
Sixty Australian aged care facilities.PARTICIPANTS:
Older adults living in aged care homes (n=654, mean age 86.7±7.2 years, 72% females). Intervention Facilities randomly allocated to a high-protein (n=30 intervention) or regular (n=30 controls) menu. MEASUREMENTS Nutritional status assessed using the Mini Nutrition Assessment (MNA) tool and fasting morning blood samples (n=302) assayed for haemoglobin (Hb) and albumin. Food intake was monitored 3-monthly using visual plate waste assessment. Measurements at baseline and month 12 were analysed using random effects model accounting for clustering (facility), repeated measure and confounders.RESULTS:
Addition of 11g of protein as 1.5 servings of high-protein foods daily preserved nutritional status that deteriorated in controls [MNA screen (-0.68, 95%CI -1.03, -0.32, p<0.001) and total (-0.90, 95%CI -1.45, -0.35, p=0.001) scores], resulting in group differences in MNA screen (0.62, 95%CI 0.17, 1.06, p=0.007) and total (0.81, 95%CI 0.11, 1.51, p=0.023) scores and group difference in Hb (3.60g/L, 95%CI 0.18, 7.03, p=0.039), the net result of preservation with intervention (0.19g/L, 95%CI -2.04, 2.42, p=0.896) and a decline in controls (-3.41g/L, 95%CI -6.01, -0.82, p=0.010). No group differences were observed for serum albumin.CONCLUSION:
Consumption of high-protein foods is a pragmatic approach to maintaining nutritional status in older adults in aged-care.Palavras-chave
