Anti-inflammatory diet and low muscle mass among older adults: a cohort study based on clhls

There is limited evidence on a longitudinal association between an anti-inflammatory diet (AID²) and low muscle mass (LMM³) in older adults. This study used data from the 2011-2017 Chinese Longitudinal Survey of Health and Longevity (CLHLS) to analyze the association between AID and LMM risk using cox regression models. At the same time, restricted cubic spline analysis and subgroup analysis were carried out. The study involved 675 elderly people in China. The incidence of low muscle mass was 34.67 %. The anti-inflammatory diet had a significant protective effect on muscle mass in older adults (HR = 0.82, 95 % CI: 0.70-0.96). In addition, the LMM risk was 32 % lower in the high AID rating group (T2) compared to the low AID rating group (T1). We encourage older adults to improve muscle mass by increasing their anti-inflammatory dietary intake to prevent or delay the onset of sarcopenia.
