To investigate the relationship between Dietary Inflammatory Index (DII) and sarcopenia in older adults and to provide a scientific basis for the prevention and treatment of sarcopenia.
From January 2022 to January 2023, 253 older adults over 60 years old were recruited in Chengdu. DII were calculated according to the semi-quantitative food frequency questionnaire, and the groups were divided into Q1-Q4 according to the DII from low to high, sarcopenia was diagnosed according to Asian Working Group for sarcopenia 2019. The relationship between DII and sarcopenia was estimated by logistic regression analysis.
After controlling confounding factors, compared with the Q1 group, the risk of sarcopenia in the Q3 group and Q4 group was 3.94 times and 7.02 times higher than that in the Q1 group (P<0.05), and the risk of sarcopenia increases in older adults with higher DII.
Higher DII increases the risk of sarcopenia, and it is recommended to provide dietary guidance for older adults to reduce the risk of sarcopenia affected by DII.
