Risk factors predicting fractures in early postmenopausal women

Area of Science:

• Gerontology
• Epidemiology
• Osteoporosis Research

Background:

• Few studies assess fracture prediction in women aged 50-59.
• Most fractures in this group occur outside osteoporotic bone mineral density (BMD) ranges.
• Fractures in this age group incur significant costs and loss of quality-adjusted life years.

Purpose of the Study:

• To identify clinical risk factors predicting subsequent fractures in women aged 50-59.
• To evaluate the utility of traditional risk factors and BMD in this population.

Main Methods:

• A cohort of 546 rural women (aged 50-59) with prior osteoporosis screening data were surveyed 8.3 years later.
• Data collected included prior fracture history, rheumatoid arthritis, menopause age, and subsequent fractures.
• Logistic regression analysis was used to identify predictive variables.

Main Results:

• The response rate was 55%, with 11.9% of respondents reporting subsequent fractures.
• Prior fracture history, rheumatoid arthritis, and menopause age <40 were initially associated with fractures.
• Logistic regression identified prior fracture history and menopause age ≤40 as significant predictors.

Conclusions:

• Prior fracture history and early menopause (age ≤40) are key predictors of subsequent fractures in women aged 50-59.
• Traditional risk factors like BMD and FRAX scores were not significantly associated in this study.
• Clinical assessment of fracture history and menopause age is vital for risk stratification in this demographic.
