Bone mineral density in Turkish postmenopausal women

Area of Science:

• Bone Metabolism and Endocrinology
• Osteoporosis Research
• Geriatric Medicine

Background:

• Postmenopausal osteoporosis is a significant health concern globally.
• Establishing population-specific bone mineral density (BMD) data is crucial for accurate diagnosis and management.
• Understanding risk factors for bone loss in diverse populations is essential for targeted interventions.

Purpose of the Study:

• To define the bone mineral density (BMD) curve in Turkish postmenopausal women.
• To assess the effectiveness of estrogen replacement therapy (ERT) in preventing bone loss.
• To identify risk factors associated with accelerated bone loss in this demographic.

Main Methods:

• Prospective measurement of spinal bone mineral density (BMD) using dual-photon absorptiometry in 118 postmenopausal women.
• Statistical analysis (Student's t-test, chi-squared test) to correlate BMD with parity, and previous/current estrogen use.

Main Results:

• A significant proportion (62.5%) of the study population had a mean BMD < 1.0 g/cm2, with 33.7% classified as osteoporotic (< 0.9 g/cm2).
• Surgical menopause was associated with faster and more intense bone loss compared to natural menopause (P < 0.05).
• High parity (after fourth delivery) and longer duration of natural menopause (≥5 years) were linked to reduced BMD.

Conclusions:

• There is a critical need for country-specific normal BMD values.
• High parity, surgical menopause, and prolonged natural menopause are identified as significant risk factors for bone loss.
• Estrogen replacement therapy demonstrates a beneficial effect in reducing annual bone loss.
