Background:

• Osteoporosis poses a significant health risk to postmenopausal women.
• Accurate risk assessment tools are needed to guide bone densitometry referrals.
• The Simple Calculated Osteoporosis Risk Estimation (SCORE) questionnaire is a validated tool for osteoporosis risk assessment.

Purpose of the Study:

• To develop and validate a Canadian version of the SCORE questionnaire.
• To assess the reliability and validity of the Canadian SCORE in identifying women at risk for osteoporosis.
• To determine optimal SCORE cut-points for different age groups of postmenopausal women.

Main Methods:

• A prospective study involving 307 postmenopausal women aged 50-70 years across 20 Canadian sites.
• Comparison of SCORE results with bone mineral density measurements (hip and lumbar spine) obtained via dual X-ray absorptiometry.
• Receiver operating characteristic (ROC) analysis to determine optimal SCORE cut-points for sensitivity and specificity.

Main Results:

• A SCORE cut-point of 6 demonstrated high sensitivity (0.96) and moderate specificity (0.51) for women aged 50-59 with low bone density (T-score ≤ -2.0).
• For women aged 60-70, a SCORE cut-point of 8 yielded a sensitivity of 0.90 and specificity of 0.20.
• The test-retest reliability of the Canadian SCORE was high, with an intraclass correlation coefficient of 0.95.

Conclusions:

• The Canadian SCORE is a valid and reliable tool for assessing osteoporosis risk in postmenopausal women.
• Age-specific SCORE cut-points are necessary for optimal performance, with higher cut-points needed for older women.
• Implementing the SCORE questionnaire can potentially reduce healthcare costs by limiting unnecessary bone density testing.
