目的：运用超声骨密度法检测职业女性的骨密度，并分析影响骨密度的主要因素。方法：随机抽取广州市30～50岁职业女性。运用问卷调查法、超声骨密度测量法、体成分测量法进行数据采集，运用Pearson相关分析法、主成分分析法对骨密度的影响因素进行分析。结果：广州市30～34岁职业女性被评价为骨质疏松的人群占6．8％，高于其后的3个年龄组。Pearson相关分析结果显示，受教育程度、收入水平、身高、体重、肌肉重量、运动强度、高钙食品的摄入频率、运动量与骨密度呈显著性正相关（P〈0．05），腰臀比与骨密度呈显著性负相关（P〈0．05）。肌肉重量因子、受教育程度因子、体育锻炼因子、腹部肥胖因子和高钙食品摄入因子为骨密度的主要影响因素（因子）。结论：骨质疏松有年轻化倾向。适当的体育锻炼、合理的肌肉力量训练及高钙饮食等对骨密度的提升或保持有积极效应，而肥胖对骨密度产生负面影响。

This paper, on the basis of questionnaires, ultrasonic BMD （bone mineral density） testing method, body composition testing, tests the BMD of vocational women in 30- 50 years old in Guangzhou and analyzes the main factors that affect the BMD when they were randomly chosen as research object. Pearson correlation analysis and principal components analysis show that the ratio of osteoporosis of 30 - 34 year-old vocational women is 6. 8%, which is higher than other three age groups. The correlation of BMD and the education level, income, stature, body weight, muscle weight, exercise intensity, high calcium food intake frequency, and amount of exercise is significantly positive, and the correlation of waist-hip ratio and BMD is significantly negative. Component analysis finds that muscle weight factor, education level, exercise, abdominal obesity and high calcium food intake are the main factors of BMD. The result shows the tendency of osteoporosis for young people. Therefore, emphasis should be on proper sports exercise, reasonable muscle strength training and calcium-rich diet to improve the positive effect of BMD and prevent the negative effect of obesity on it.
