Abstract

A systematic review and meta-analysis was conducted to comprehensively examine the association between Dietary Inflammatory Index (DII®) score and risk of frailty. Frailty risk were available from five studies comprising 13,908 older adults. Furthermore, frailty related parameters were extacted from two studies with 7,539 individuals. A pooled adjusted odds ratio analysis indicated that there was an association between DII® score and frailty risk (OR = 1.24, 95%CI: 1.6–1.33, P < 0.001, I2 = 0.0%). The results of frailty related parameters demonstrated that DII® score was associated with weakness risk (OR = 1.12, 95%CI: 1.05–1.19, P = 0.014, I2 = 0.0%), but not other frailty-related parameters including exhaustion, low BMI or low physical activity. The results of this meta-analysis suggest that older adults who exhibit higher DII® scores have an increased frailty risk. Further prospective cohort studies with longer follow-up periods, are needed to support this possible association between DII® score and frailty risk. © The Author(s) 2020.
