福州市青少年骨密度影响因素的调查分析

Investigation and Analysis on the Influence Factors of the Fuzhou Teenagers Bone Mineral Density

为了解骨密度的影响因素,采用了资料分析法、问卷调查法、测试法等方法,对福州市青少年的骨密度及其生活习惯进行调查和分析。结果显示:城乡青少年的骨密度呈现随年龄增长而增加的趋势,且同年龄组中女生的高于男生,城市高于乡村;城乡青少年的对补钙的认识不足、补钙量不足;补钙、少喝碳酸饮料、均衡膳食及已发育者的骨密度较高;运动次数和时间对骨密度的影响有待进一步研究。因此,要提高青少年的骨密度,就要培养青少年良好的饮食和运动习惯,在保障每天一盒以上牛奶的基础上,给予适当的钙剂补充,并做到均衡膳食。
