目的探讨呼和浩特地区中老年人骨质疏松的患病情况,为呼和浩特地区老年病的防治和老年人群的骨保健提供资料。方法采用美国GE公司生产的LUNAR-Bravo双能X线骨密度仪对呼和浩特地区500对汉族中老年夫妇进行骨密度(BMD)测定。结果①按年龄分组,从45岁以后开始男性和女性随着年龄的增大,BMD值和T值逐渐降低,女性降低幅度明显高于男性(P<0.05)。②女性在55岁以后可见明显的骨量丢失加速,男性是逐渐和缓慢的。女性的患病率明显高于男性(P<0.05)。③BMD测定结果与年龄的相关性分析显示,BMD值和T值与年龄呈显著的负相关(P<0.05),女性相关性更强。结论呼和浩特地区汉族中老年人群随着年龄的增长,BMD逐渐降低,骨质疏松患病率明显增加,女性更为明显,但比其他地区(广州、上海、长沙、成都等地区)报道骨质疏松的发生的年龄推迟,这与呼和浩特地区特殊的地理环境和饮食习惯有关。
Objective To investigate the prevalence of osteoporosis in middle-aged and elderly people in Hohhot and to provide information on prevention and treatment of geriatric diseases and bone health in the elderly in Hohhot. Methods The bone mineral density (BMD) was measured in 500 Han Chinese middle-aged and elderly couples in Hohhot by LUNAR-Bravo dual-energy X-ray absorptiometry. Results ①According to age group, from the age of 45, men and women began to decrease in BMD value and T value with the increase of age. The decrease rate of female was significantly higher than that of male (P <0.05). ② women in 55 years after the apparent increase in bone loss accelerated, men are gradually and slowly. The prevalence of women was significantly higher than that of men (P <0.05). ③ The correlation analysis of BMD results with age showed that BMD value and T value had a significant negative correlation with age (P <0.05), and the correlation between women and men was stronger. CONCLUSIONS: With the increase of age, the prevalence of osteoporosis in the middle-aged and elderly population of Han nationality in Hohhot is gradually decreased, the prevalence of osteoporosis is significantly increased, and the female is more obvious. However, compared with other regions (Guangzhou, Shanghai, Changsha, Chengdu and other regions) The postponement of the occurrence of age, which is related to the special geographical environment and eating habits in Hohhot.
