Background:
Osteoporotic fracture is a major health burden. Early diagnosis and management would improve the quality of life and reduce costs to the society.
Objective:
We aimed to identify risk factors associated with osteoporosis followed by development and validation of a screening tool in the hope of providing an appropriate regime to detect low bone density (BMD) in Malaysia.
Methodology:
Between November 1999 and November 2002, 514 healthy women aged ≥ 45 with intact uterus, non-HRT users were recruited. Following BMD testing, a screening tool was developed. For validation, 72 women were recruited from June 2003 to December 2003.
Results:
Age and a longer duration postmenopause were negatively linked to BMD. Higher family income, BMI, waist and hip circumference were positively correlated. A score of ≥ 4, the screening tool had a sensitivity of 73.2%, a specificity of 61.6% for identifying women with low BMD (T score ≤ -2) plus a sensitivity of 80.2% in selecting women with osteoporosis. The tool enabled a 45.9% reduction in unnecessary DEXA testing. Validation of the screening tool showed a negative predictive value of 97.8%, sensitivity and specificity of 87.5% and 70.3%, respectively.
Conclusion:
The Malaysian Osteoporosis Screening Tool (MOST) is relatively simple. Its usage may reduce unnecessary DEXA test.

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...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
