目的

探究脑小血管病(CSVD)患者的体脂和肌肉含量与神经影像学标志物之间的关系。

方法

纳入2022年1月1日至2023年6月1日中国人民解放军总医院第七医学中心神经内科诊断为CSVD的住院患者95例。获取患者体质量、蛋白含量和基础代谢率、体脂百分比(BF)、标准化骨骼肌质量(ASM)等身体成分指标。纳入的CSVD神经影像标志物包括腔隙性脑梗死(LI)、白质高信号(WMH)、脑微出血(CMB),对上述特征进行计算整合从而得出CSVD综合评分。按性别分层,采用二元或有序Logistic回归分析身体成分与CSVD神经影像标志物和综合评分的关联。

结果

在男性患者(48例)中,无论是BF还是ASM均与CSVD综合评分存在关联,随着综合评分的增加,BF显著增加(OR=1.117,95%CI:1.021~1.222,P=0.016),而ASM显著减低(OR=0.185,95%CI:0.057~0.602,P=0.005);但在女性患者(47例)中,随着CSVD综合评分的增加,只有BF显著升高(OR=1.059,95%CI:1.071~1.343,P=0.002)。此外,分析某一单项神经影像标志物时,本研究仅发现在男性患者中ASM与WMH存在独立相关(OR=0.099,95%CI:0.032~0.311,P<0.001)。

结论

CSVD患者体脂及肌肉含量与CSVD综合评分的关联比CSVD任何单一神经影像标志物都更为显著,表明相关身体成分对CSVD的影响更多地反映在疾病的整体负荷上。

Objective

To investigate the association between body composition (specifically body fat and muscle mass) and neuroimaging markers in patients with cerebral small vessel disease (CSVD).

Methods

Ninety-five hospitalized patients diagnosed with CSVD at the Seventh Medical Center of the Chinese PLA General Hospital between January 1, 2022, and June 1, 2023, were enrolled. Body composition parameters assessed including body weight, protein content, basal metabolic rate, body fat percentage (BF), and appendicular skeletal muscle mass (ASM). CSVD neuroimaging markers included lacunar infarcts (LI), white matter hyperintensities (WMH), and cerebral microbleeds (CMB). A composite CSVD score was calculated by integrating these markers. Sex-stratified binary or ordinal logistic regression analyses were performed to evaluate relationships between body composition and both individual neuroimaging markers and the composite CSVD score.

Results

Among male patients (n=48), higher composite CSVD scores were significantly associated with increased BF (OR=1.117, 95%CI: 1.021–1.222, P=0.016) and decreased ASM (OR=0.185, 95%CI: 0.057–0.602, P=0.005). In female patients (n=47), only BF showed a significant positive correlation with composite scores (OR=1.059, 95%CI: 1.071-1.343, P=0.002). In addition, when analyzing individual neuroimaging markers, ASM was independently associated with WMH in males (OR=0.099, 95%CI: 0.032-0.311, P<0.001), whereas no significant associations were observed in females.

Conclusion

Body fat and muscle mass in CSVD patients exhibit stronger correlations with composite CSVD scores than with individual neuroimaging markers, suggesting that these body composition metrics may as indicators of global CSVD burden rather than specific pathological features.
