Abstract
Context The relationship of visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) with bone mineral density (BMD) is not well established. Objective To examine the associations of VAT and SAT with total body BMD in a large, nationally representative population with a wide range of adiposity. Methods We analyzed 10,641 subjects aged 20-59 in NHANES 2011-2018 who had undergone total body BMD and had VAT and SAT measured by DXA. Linear regression models were fitted while controlling for age, gender, race or ethnicity, smoking status, height, and lean mass index. Results In a fully adjusted model, each higher quartile of VAT was associated with an average of 0.22 lower T-score (95% CI -0.26 - -0.17, p < 0.001), while SAT had a weak association with BMD but only in men (-0.10, 95% CI -0.17 - -0.04, p = 0.002). However, the association of SAT to BMD in men was no longer significant after controlling for bioavailable sex hormones. In subgroup analysis, we also found differences in the relationship of VAT to BMD in Black and Asian subjects, but these differences were eliminated after accounting for racial and ethnic differences in VAT norms. Conclusions Visceral adipose tissue has a negative association with BMD. Further research is needed to better understand the mechanism of action and, more generally, to develop strategies for optimizing bone health in obese subjects.This publication has 43 references indexed in Scilit:
