Introduction:
To investigate the relationship between serum high-density lipoprotein (HDL) cholesterol and bone mineral density (BMD) in vitamin D-deficient population.
Materials And Methods:
This study was a cross-sectional study. From January to December 2020, 2583 middle-aged and older adult aged 40 and above were randomly selected in the Health Management Center of the Affiliated Hospital of Guizhou Medical University for health examination and questionnaire survey. The correlation was determined by Pearson correlation method, and the independent correlation was analyzed by multiple linear regression. The receiver Operating characteristic (ROC) curve estimates HDL-C cutoff levels for predicting osteoporosis risk.
Results:
The prevalence of osteoporosis in the study population was 11.4%, the overall prevalence of 25 (OH) D deficiency was 78.2%. There was no correlation between HDL-C and BMD of lumbar spine, femoral neck and total hip in normal vitamin D group (P > 0.05). HDL-C in the deficient group was negatively correlated with BMD of lumbar spine and femoral neck (P < 0.05), but not with BMD of total hip. Serum HDL-C concentration increased with the progression of osteoporosis. When serum 25 (OH) D level was lower than normal level, HDL-C ≥ 1.215 mmol/L was an independent predictor of osteoporosis (sensitivity = 75%, specificity = 53%, Area = 0.625).
Conclusions:
HDL-C was inversely associated with BMD in the lumbar spine and femoral neck in people aged 40 years and older with vitamin D deficiency. When serum HDL-C concentration ≥ 1.215 mmol/L, it can better predict the occurrence of osteoporosis.

01:25Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
