Abstract
Introduction: Chronic inflammation in the elderly is associated with various age-related diseases and may contribute to functional decline and reduced quality of life. An imbalance in body composition, characterized by an excess of fat and inadequate levels of muscle mass, has been identified as an underlying cause of inflammation. Numerous prognostic factors, such indexes are employed to measure inflammation. The Systemic Immune-Inflammation Index (SII) is a reliable indicator of inflammation and has been found to have a substantial correlation with mortality in numerous investigations. The goal of this paper is to examine the relationship between body composition, mortality, and SII. Methods: This cross-sectional design utilized data from the Neyshabur Longitudinal Study on Ageing (NeLSA). The participants included in the study were 60 years old or older. SII scores were calculated using data from individual blood bank records. Data analysis involved analytical techniques such as correlation coefficient, logistic regression, and linear regression. Results: A total of 3,534 individuals took part, with 1,858 being male. The median age of participants was 65.71. The study revealed a notable association between the percentage of body fat and SII (p<0.001). The overall mortality rate was 0.93 in 1000. Mortality was linked to SII after adjusting for confounding variables (OR = 1.001, 95% CI = 1.000 to 1.002, P = 0.047). Conclusion: SII only correlated with blood pressure and body fat. A weak correlation observed between SII and hs-CRP, which was linked to overall mortality in the elderly.
