A review in the Journal of the American Geriatrics Society, based on four studies with 5,789 older adults, found adherence to a Mediterranean diet was linked to a reduced risk of incident frailty. Researchers called for additional studies to confirm the results.
Gotaro Kojima, M.D., from University College London, and colleagues conducted a systematic review to examine incident frailty risk associated with adherence to a Mediterranean diet among community-dwelling adults aged 60 and older. Data were included from four studies with 5,789 older people and mean follow-up of 3.9 years.
The researchers found that greater adherence to a Mediterranean diet was correlated with a significantly reduced risk of incident frailty compared with poorer adherence (pooled odds ratios, 0.62 and 0.44 for Mediterranean diet scores of 4 to 5 and 6 to 9 versus 0 to 3). There was no evidence of significant heterogeneity or publication bias.
“Future studies should confirm these findings and evaluate whether adherence to a Mediterranean diet can reduce the risk of frailty, including in non-Mediterranean populations,” the authors write.
