摘　　要：目的对厦门市中老年人骨密度状况进行分析,了解厦门市地区环境、生活行为、饮食习惯对骨密度的影响,为防治骨质疏松提供理论依据。方法在2007年10月至2010年10月,对在厦门居住10年以上、21岁以上共6233人,采用美国GE公司LUNAR PRODIGY型骨密度仪,测定腰椎1-4、股骨颈、Ward三角、大转子区的骨密度,并以5岁为年龄组间距进行分组,对每组的身高、体重、性别、骨密度进行分析比较。结果骨密度随年龄增高而下降,男女在36～40岁这一年龄段的骨密度相对稳定为最高值。35岁至50岁(女性),35岁至65岁(男性)相对稳定。女的从56～60岁开始下降,男的从66～70岁开始下降。身高随年龄增高而下降,36～40岁这一年龄段平均男人身高174.2cm,女人身高162.8cm;80岁以后身高都变矮,男人平均为168.4cm,女人平均为155.7cm,女人身高变矮比男人明显。体重在36～40岁,男人的体重平均达70.1kg,女人的体重平均达60.8kg。结论厦门地区的环境、气候及较长的海岸线和全年都有日照,可提供很多户外活动的空间,厦门人的生活行为、饮食习惯使厦门人骨密度随年龄增高而下降的速度较慢。年龄往后移,身高体重适宜,肥胖的人不多。Objective To investigate the status of bone mineral density （BMD） in middle-aged and elderly adults in Xiamen city, to understand the effect of geographic factors, life style, and dietary habit on BMD, and to provide theoretical evidence for prevention and treatment of osteoporosis. Methods BMD was measured in 6233 subjects who had lived in Xiamen for over 10 years and were over 21 years older, from October 2007 to October 2010. The subjects were divided into groups by every 5-year-old interval. The height, weight, gender, and BMD were compared among the groups. BMDs of the lumbar vertebrae 1-4, the femoral neck, Ward＇s triangle, and the greater trochanter region were measured with an absorptiometer （Lunar Prodigy, GE Inc, USA）. Results BMD decreased with aging. BMD was stable and at a high value in 36-50-year-old group both in males and females. It was stable in 35-50-year-old group in males and 35- 65-year-old group in females. BMD began to decrease from 56-60 years old in females, and 66-70 years old in males. The height decreased with aging. The average height was 174. 2 cm in males and 162.8 cm in females at 36-40 years old. It decreased to 168.4 cm in males and 155.7 cm in females at 80 years old. The decrease was more obvious in females than in males. The average body weight was 70.7 kg in males and 60.8 kg in females at 36-40 years old. Conclusion Due to the environment in Xiamen city, such as climate, long coastline, all year sunshine, more outdoor activity can be provided. The life style and dietary habit of individuals in Xiamen cause the decline speed of BMD with aging more slowly. They cause that the age for the occurrence of osteoporotic becomes older, and the height and weight are appropriate, and the obese people are not popular.
