研究通过分析吸烟与绝经后老年妇女骨密度之间的关系,以及吸烟对骨与矿物质代谢变化的影响,从而探讨吸烟影响骨代谢的确切机制。选择65～77岁的老年女性444例,根据吸烟程度分为不吸烟组、少量吸烟组(<1包/日)和大量吸烟组(>1包/日)。作相关生化检查和使用双能X线骨密度测量仪对腰椎(L1～L4)、髋骨、股骨近端全身以及桡骨中段的骨密度(BMD)进行测定。结果发
The study explores the exact mechanism by which smoking affects bone metabolism by analyzing the relationship between smoking and bone mineral density in elderly postmenopausal women, and the effects of smoking on changes in bone and mineral metabolism. A total of 444 elderly women aged 65-77 years were selected and divided into non-smoking group, a small number of smoking group (<1 pack / day) and a large number of smoking group (> 1 pack / day) according to the degree of smoking. The bone mineral density (BMD) of the lumbar vertebra (L1 ~ L4), the hip, the whole proximal femur and the middle of the radius were measured by biochemical examination and dual energy X-ray absorptiometry.
