摘要

目的：氧化应激被认为会增加骨折风险，而脂质氧化会对骨骼健康产生不利影响。4-羟基壬烯醛（4-HNE）是脂质氧化的代表性标志物：我们调查了社区居住的老年人（人数=78，平均年龄=78 岁）中 4-HNE 与骨折风险之间的关系。我们使用骨折风险评估工具（FRAX®）对血清白蛋白、C 反应蛋白和 4-HNE 值进行了检测。FRAX®得分>15%被定义为高骨折风险：结果：骨折高风险组（38 人，中位数为 12.4 纳克/毫升）的 4-HNE 值明显高于低风险组（40 人，中位数为 9.8 纳克/毫升；P=0.02）。经多种变量调整后，FRAX®严重骨质疏松症（β=0.45）和FRAX®髋部骨折（β=0.44）与4-HNE的相关性显著：结论：4-HNE 与骨折风险呈正相关。结论：研究表明，4-HNE 与骨折风险呈正相关，该分子可能是老年人骨折风险的临床候选氧化应激标志物。

Communication: 4-Hydroxynonenal and Fracture Risk in the Community-Dwelling Older People.

Objective: Oxidative stress is considered to increase fracture risk, and lipid oxidation can adversely affect bone health. 4-hydroxynonenal (4-HNE) is a representative marker of lipid oxidation.

Methods: We investigated the association between 4-HNE and fracture risk in community-dwelling older subjects (n=78, mean age=78 years). Serum albumin, C-reactive protein, and 4-HNE values were examined with the Fracture Risk Assessment Tool (FRAX®). The FRAX® score of >15% was defined as a high fracture risk.

Results: There was a significantly higher 4-HNE value in the group of high fracture risk (n=38, median=12.4 ng/mL) than in the low-risk group (n=40, median=9.8 ng/mL; p=0.02). The correlation of FRAX® major osteoporosis (β=0.45) and FRAX® hip fracture (β=0.44) with 4-HNE was significant after adjustment for multiple variables.

Conclusions: 4-HNE was suggested to be positively associated with fracture risk. This molecule may be a clinical candidate oxidative stress marker for fracture risk in the older population.
