摘　　要：目的　探索广州地区正常人群骨密度 (BMD)的变化规律。方法　采用美国Lunar公司的双能X线骨密度仪对广州地区 5 0 3名 2 0～ 4 9岁居民进行腰椎 2～ 4和髋部骨密度测量。结果　男性腰椎骨密度峰值在 2 0～岁 ,男性髋部骨密度峰值均在 2 5～岁。女性腰椎骨密度峰值在 30～岁 ,女性髋部骨密度峰值在 2 5～岁。峰值后随年龄增加而骨密度下降 ,女性在 5 0～岁出现明显加速 ,男性没有加速下降现象。结论　我国男性骨密度峰值略高于女性 ,但差异无显著性 (P >0 0 5 ) 。Objective\ To study the regularities of change in bone mineral density (BMD). Methods\ The BMD of L 2-4 and hip were measured by Lunar plus dual enengy X\|ray absorptiometry (DEXA) for 503 people (247 men and 256 women, aged 20-49 years). Results\ The BMD peak values of L 2-4 were seen in 20\|year old group for males and in 30\|year old group for females.However,the peak bone mass of hip was found in 25\|year old groups of bothe sexes.Afterwards BMD diminished with increasing age.The bone loss was sharply decreased for females after 50 years of age,but that of males was progressive and slow. Conclusion\ The peak values in males was higher than that of females in Guangzhou.The age of peak values in males is younger than that in females.
