对我部驻甘肃集训练基地某站干部、战士、志愿兵及家属１０６人进行了骨密度调查。调查采用单光子骨矿分析仪，对尺、桡骨的骨密度进行测定。结果表明，骨密度良好者占 ６５．１％，与对照组 １０．１％相比，有非常显著性差异（Ｐ＜０．０１）。经调查，该地区饮用水硬度明显偏高，说明饮用水中钙含量与骨密度有直接关系。
A BMD survey was conducted on 106 officers, soldiers, volunteers, and family members of a certain station in Gansu Province. The single-photon bone mineral analyzer was used for the investigation to determine the bone density of the feet and sacrum. The results showed that 65.1% of those with good bone density were compared with 10.1% of the control group (P<0.01). After investigation, the hardness of drinking water in the area is significantly higher, indicating that the calcium content in drinking water is directly related to bone mineral density.
