Systemic Inflammation Markers Associated with Bone Mineral Density in perimenopausal and Postmenopausal Women.

OBJECTIVE

The aim of this research was to determine whether systemic inflammatory indicators, including aggregate index of systemic inflammation (AISI), neutrophils lymphocyte to platelet ratio (NLPR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI), are related to bone mineral density (BMD) in perimenopausal and postmenopausal women.

METHODS

One hundred and eighty-one perimenopausal and 390 postmenopausal women were enrolled in this cross-sectional study. Continuous variables by analysis of variance and Kruskal Wallis test for comparing the clinical characteristics. Linear regression analysis was conducted to investigate the associations between inflammatory indicators with BMD. The comparison between the subgroups was performed using the nonparametric test and the -test.

RESULTS

AISI, NLPR, SII, and SIRI quartile values were inversely associated with BMD in menopausal women ( = 0.021; = 0.047; < 0.001; < 0.001, respectively). After adjusting for confounding factors, four inflammatory indicators remained significantly associated with BMD (all for trend <0.001). Analysis according to menopausal status demonstrated that AISI, SII, and SIRI were significantly correlated with mean femoral neck BMD in postmenopausal women ( for trend = 0.015, 0.004, and 0.001), but not significantly associated with BMD in perimenopausal women ( for trend = 0.248, 0.054, and 0.352) after adjustment for covariates.

CONCLUSION

The quartile values of AISI, SII, and SIRI were inversely associated with BMD in postmenopausal women, following adjustment for individual variables, hormone profiles and glucolipid metabolism profiles. AISI, SII, and SIRI have potential to be important tools for screening and prevention of bone loss in menopausal women in future clinical practice.
