Association between fibrinogen and bone mineral density in postmenopausal women
Abstract
OBJECTIVE: There is very limited of evidence linking fibrinogen and bone mineral density (BMD) in postmenopausal women. Therefore, this study intended to examine the relationship between fibrinogen and total BMD in postmenopausal women.
METHODS: This cross-sectional analysis included 2043 postmenopausal women aged 50 years and older from the 1999 to 2002 National Health and Nutrition Examination Survey. The independent variable was fibrinogen and the outcome variable was total BMD. The association between fibrinogen and total BMD in postmenopausal women was examined using multivariate linear regression models, with subgroup analyses stratified by race. Smoothing curve fitting and generalized additive models further analyzed the sample data.
RESULTS: In multiple regression models adjusted for potential confounders, fibrinogen was negatively associated with total BMD (model 1: - 0.0002 [- 0.0002, - 0.0001], model 2: - 0.0000 [- 0.0001, - 0.0000], model 3: - 0.0001 [- 0.0001, - 0.0001]). In subgroup analysis stratified by race, fibrinogen levels were negatively associated with total BMD in postmenopausal women, Non-Hispanic Whites, and Mexican Americans. However, in Non-Hispanic Blacks, the correlation between fibrinogen levels and total BMD was not significant. For individuals that identify as Other Races, fibrinogen levels were positively correlated with total BMD.
CONCLUSION: Our findings show a negative association between fibrinogen levels and total BMD in most…
