Background/Purpose
In this study, our aim was to evaluate the effects of individual dietary counseling as part of a comprehensive geriatric assessment (CGA) on frailty status among community-dwelling people aged 75 years or older.Methods
Data were obtained from a subpopulation of participants in the population-based Geriatric Multidisciplinary Strategy for the Good Care of the Elderly (GeMS) intervention study in 2004 to 2007. In the present study, the population consisted of 159 persons at risk of malnutrition in the year 2005 in an intervention and a control group. Nutritional status was assessed with the Mini Nutritional Assessment (MNA). Frailty was defined according to the five frailty criteria used in the Cardiovascular Health Study (CHS). Assessment of nutritional status and frailty status was performed at the beginning of the study and at 1-year follow-up.
Results
At baseline the mean age of the 159 community-dwelling participants with risk of malnutrition was 83 years and 126 (79 % ) of them were female. The proportions of frail and pre-frail persons were 25 % (n?=?19) and 61 % (n?=?47) in the intervention group, and 26 % (n?=?21) and 61 % (n?=?50) in the control group. After the 1-year nutritional intervention, compared to the control group, the intervention group tended to have a better outcome of frailty and MNA (OR?=?1.89, 95 % CI: 1.08-3.54, OR?=?2.61, 95 % CI: 1.67-5.56, respectively) and was less likely to deteriorate as assessed with MNA (OR?=?0.23, 95 % CI: 0.14-0.87). In multivariate analysis, change in MNA (OR?=?1.12, 95 % CI: 1.03-1.31) was associated independently with improved frailty status.
Conclusion
It appears that multidisciplinary geriatric assessment including individual dietary counseling has a positive effect on frailty status. More emphasis on good nutrition in the older population might have a preventive effect on the incidence of frailty.
