In a study out of Massachusetts General Hospital and Harvard Medical School, researchers investigated the association between fat levels in the blood and that within an obese person’s bone marrow. High levels of bone marrow fat has previously been shown to correlate to low bone mineral density and increased fracture risk.

Brendella et al. found elevated blood triglyceride and low high-density lipoprotein cholesterol to be associated with a high fat content in bone marrow.
