The aim of this study was to assess site-specific relationship of hand bone mineral density (BMD) with hand size, pinch and grip strength in healthy people aged 19-50 years. A total of 143 healthy volunteers participated in the study (mean age: 34 years). One hundred-six were premenopausal women (mean age: 34 years) and 37 were men (mean age: 34 years). Grip and pinch strength was measured by a Jamar dynamometer (Jamar, Irvington, NY). Second, third and fourth middle phalanx BMD were measured on a MetriScan densitometer (Hayward, CA) and mean value of these three phalanxes were used in the analysis. There was not a significant correlation between hand BMD and grip, pinch strength or hand size in premenopausal women. A significant correlation between hand BMD and grip strength was found in men (right hand; r=0.44, p=0.007, left hand; r=0.33, p=0.05). Hand size was not correlated with hand BMD both in men and in women. The short-term precision for RA was estimated as 0.44%. This is the first report of a site-specific relationship of BMD measured by radiographic absorptiometry with hand size, pinch and grip strength in healthy men and premenopausal women. Our results revealed that there is a moderate correlation between hand-grip strength and hand BMD in men. Hand size does not predict hand BMD both in men and women. Radiographic absorptiometry is a practical and reproducible method to detect bone mineral density of hands and may be a valuable screening tool for osteoporosis.
本研究旨在评估19至50岁健康人群手部骨密度（BMD）与手大小、捏力和握力之间的部位特异性关系。共有143名健康志愿者参与了该研究（平均年龄：34岁）。其中106名是绝经前女性（平均年龄：34岁），37名是男性（平均年龄：34岁）。握力和捏力通过Jamar测力计（Jamar，纽约州欧文顿）测量。第二、第三和第四中指骨的骨密度通过MetriScan骨密度仪（加利福尼亚州海沃德）测量，并将这三个指骨的平均值用于分析。绝经前女性的手部骨密度与握力、捏力或手大小之间无显著相关性。在男性中发现手部骨密度与握力之间存在显著相关性（右手；r = 0.44，p = 0.007，左手；r = 0.33，p = 0.05）。男性和女性的手大小均与手部骨密度无关。RA的短期精密度估计为0.44%。这是首篇关于通过放射吸收法测量的骨密度与健康男性和绝经前女性的手大小、捏力和握力之间部位特异性关系的报告。我们的结果显示，男性的握力与手部骨密度之间存在中度相关性。男性和女性的手大小均不能预测手部骨密度。放射吸收法是一种检测手部骨密度的实用且可重复的方法，可能是一种有价值的骨质疏松症筛查工具。
