Study finds link between cholesterol ratio and lower fracture risk in hospital patients
Frontiers in Medicine
Published March 31, 2026
Researchers looked at whether a specific cholesterol measurement in the blood, called the non-HDL to HDL cholesterol ratio (NHHR), was linked to the risk of having an osteoporotic fracture. They studied 580 patients from the endocrinology department at a hospital in China. The study was retrospective, meaning it looked back at existing medical records, and cross-sectional, meaning it captured data at a single point in time.
The main finding was that patients with a higher NHHR had lower odds of having an osteoporotic fracture. The relationship followed a pattern where the highest levels of this ratio were linked to the lowest fracture odds. The analysis also suggested this link was not a straight line, but changed at a specific point.
No safety concerns were reported, as the study only measured cholesterol levels and did not involve any treatment. The main reason to be careful is the study's design. Because it looked at data from one moment and did not follow people over time, it can only show an association, not prove that the cholesterol ratio actually prevents fractures. Readers should view this as an early finding from one hospital's patient group that needs to be confirmed by different types of studies in broader populations.

BackgroundThe non-high-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (NHHR) has emerged as a valuable lipid marker associated with various cardiometabolic diseases. Although evidence links lipid metabolism to skeletal health, the relationship between NHHR and osteoporotic fractures remains unexplored. This study aims to assess the association between NHHR and the risk of osteoporotic fractures.MethodThis retrospective cross-sectional study included 580 patients from the Department of Endocrinology at Gansu Provincial People's Hospital between January 2020 and December 2024. The association between NHHR and osteoporotic fracture was assessed using multivariate logistic regression with covariate adjustment. RCS analysis explored non-linear relationships, and comprehensive subgroup analyses validated the findings' consistency.ResultsIn fully adjusted multivariate logistic regression models, NHHR demonstrated a significant inverse association with osteoporotic fracture (OR = 0.55, 95% CI: 0.45–0.66, p < 0.001), with each one-unit increment corresponding to a 45% reduction in fracture odds. Categorical analysis by NHHR quartiles confirmed a dose-response relationship, with participants in the highest quartile exhibiting 80% lower odds of fracture compared to the reference lowest quartile (OR = 0.20, 95% CI: 0.11–0.36, p < 0.001). Restricted cubic spline regression revealed a significant non-linear relationship (p for non-linearity < 0.001) with an inflection point identified at NHHR = 3.29. In stratified analyses, the inverse association between NHHR and osteoporotic fracture persisted across all demographic subgroups.ConclusionsOur study identified a significant non-linear association between NHHR and osteoporotic fracture risk. Due to its retrospective nature, further prospective investigations are needed to confirm these [r]results.
