The effect of the serum lipid levels on vertebral fractures and bone mineral density is not clear. A total of 107 postmenopausal women aged 45-79 examined by lumbar spine, hip and radius bone mineral density (BMD) measurements, lateral dorsal and lumbar spine radiographies, routine blood tests and serum lipids [total cholesterol (TC), triglyceride (TG), HDL-C, LDL-C, VLDL-C]. Demographic and lifestyle characteristics were collected. Eighty-nine radiographies with good technical properties were scored by the Kleerekoper method. Patients with vertebrae fractures had lower levels of TC, TG, LDL-C than the patients without vertebrae fractures. Total cholesterol level was the most prominent factor affecting the vertebral fracture existence. An increase of 1 mg/dl total cholesterol decreases the risk of vertebrae fracture by 2.2%. The existence of osteoporosis due to T score was not influencing the lipid values. TC and LDL-C were weakly associated with BMD at the forearm UD region after the adjustment for the possible confounders. This study shows that the serum lipids have impact on vertebrae fracture existence rather than BMD alterations.
血清脂质水平对椎体骨折和骨密度的影响尚不清楚。共有107名年龄在45 - 79岁的绝经后女性接受了腰椎、髋部和桡骨骨密度(BMD)测量、腰椎和胸椎侧位X线摄影、常规血液检查以及血清脂质检测[总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、极低密度脂蛋白胆固醇(VLDL-C)]。同时收集了人口统计学和生活方式特征。采用Kleerekoper方法对89份技术质量良好的X线片进行评分。椎体骨折患者的TC、TG、LDL-C水平低于无椎体骨折的患者。总胆固醇水平是影响椎体骨折发生的最显著因素。总胆固醇每增加1mg/dl,椎体骨折风险降低2.2%。T评分所反映的骨质疏松的存在并不影响脂质值。在对可能的混杂因素进行校正后,TC和LDL-C与前臂远端区域的骨密度呈弱相关。本研究表明,血清脂质对椎体骨折的发生有影响,而非对骨密度改变有影响。
