Objective To analyze the relationship between high-density lipoprotein cholesterol(HDL-C)and bone mineral density in healthy physical examination populations to provide guidance for the prevention and treatment of osteopo-rosis.Methods This study was a retrospective study that collected 17,448 physical examination people from September 2018 to February 2023 in the health management discipline of Henan Provincial People's Hospital.All participants under-went physical examination,lipid profile and quantitative CT(QCT)to measure their lumbar spine bone density.Pearson and Spearman correlation analysis was used to evaluate the correlation between each index and bone density,and multiple linear regression analysis was used to further analyze the relationship between HDL-C and bone density.Results According to bone mineral density,the mean value of serum HDL-C in the osteoporosis group was significantly higher than that in the os-teopenia and normal bone mass group(P<0.05).After adjusting for other variables,the results of regression analysis showed that HDL-C levels were negatively correlated with lumbar spine bone mineral density(t=-4.364,P<0.05),and the negative correlation was more significant in the female population(t=-6.858,P<0.05).According to body mass in-dex(BMI),HDL-C level was negatively correlated with lumbar spine bone mineral density in overweight and obese people(r=-0.039,P<0.01;r=-0.126,P<0.01).There was no correlation in the BMI<24 kg/m2 group,and the differ-ence was not statistically significant(P>0.05).Conclusion Elevated serum HDL-C levels are risk factors for osteopo-rosis,and are more prominent in women and overweight and obese people,providing a scientific basis for the prevention of osteoporosis.
