This study employed dual-energy X-ray absorptiometry (DXA), a widely used and clinically safe method for assessing bone health. The DXA system (brand referenced in previous publications) operates by emitting a low-radiation dose (±10 μSv) X-ray beam to measure the extent of X-ray penetration through body tissues. Based on the absorption data, the device calculates bone mineral density (BMD). Since bones absorb more X-rays and have high penetrability, while fat absorbs less and has low penetrability, DXA effectively differentiates between tissue types. DXA results are typically interpreted using T-scores for BMD. A T-score ≥ -1.0 indicates normal bone density and good skeletal health. A T-score between -2.5 and -1.0 suggests low bone mass (osteopenia), indicating a decreased BMD but not yet at the threshold for osteoporosis. A T-score ≤ -2.5 defines osteoporosis, indicating significantly…

The Taiwan version of the World Health Organization Quality of Life questionnaire is a shortened version derived from the original 100-item WHOQOL-100 developed by the World Health Organization. Exploratory and confirmatory factor analyses of the questionnaire support a four-domain model consisting of physical health, psychological well-being, social relationships, and environment. The internal consistency (Cronbach's α) of these four domains ranges from 0.70 to 0.77. The questionnaire includes 28 items: one item for overall quality of life, one for general health, seven for physical health, six for psychological well-being, three for social relationships, and eight for environmental factors. The scale uses a 5-point Likert format based on frequency, intensity, capability, and evaluation. Higher scores indicate better quality of life.
