Risk Factors for Osteoporotic Vertebral Fractures in Postmenopausal Women: A Cross-Sectional Study

Area of Science:

• Osteoporosis research
• Geriatric medicine
• Endocrinology

Background:

• Osteoporotic vertebral fractures are a significant cause of morbidity in postmenopausal women.
• Early detection of clinical, metabolic, and densitometric risk factors is crucial for intervention and prevention.

Purpose of the Study:

• To determine the frequency of vertebral fractures in postmenopausal women.
• To identify risk factors associated with vertebral fractures in this population.

Main Methods:

• A cross-sectional study involving 220 postmenopausal women.
• Data collection included BMI, prior fragility fractures, lifestyle, demographics, reproductive history, and serum vitamin D.
• Bone mineral density (BMD) measured by DXA; vertebral fractures assessed via radiographs and graded semiquantitatively.

Main Results:

• Vertebral fractures were present in 34.5% of women.
• Factors associated with fractures included older age, longer postmenopausal duration, lower BMI, lower lumbar spine BMD, vitamin D deficiency, physical inactivity, and prior fragility fractures.
• Independent predictors identified were age ≥65, menopause duration ≥15 years, BMI <20 kg/m², lumbar spine osteoporosis, vitamin D deficiency, and prior fragility fractures.

Conclusions:

• Osteoporotic vertebral fractures are prevalent in postmenopausal women.
• Fractures are linked to age, menopause duration, low BMI, low BMD, vitamin D deficiency, and prior fractures.
• Risk assessment should extend beyond BMD to include these clinical and metabolic factors for effective early detection and prevention.
