One hundred and sixty-one very old patients (aged ≥80 years) devoid of cognitive decline were eligible for analyses. Clinical and biochemical data along with physical and cognitive assessments encompassing dual-energy X-ray scans and hand dynamometry were adopted to investigate frailty criteria, while circulating immune mediators ( and ) were assessed using high-throughput flow cytometry.
Preliminarily, correlated positively with waist-to-hip ratio and C-reactive protein and negatively with glycemia. In analyses controlled for these factors, serum levels of IL-6 were comparatively augmented among the very old participants with reduced grip strength (OR = 3.299; 95% CI 1.08-6.09; =0.032) and among those with slow walk speed (OR = 2.460; 95% CI 1.16-7.05; =0.022).
Our study shows a strong negative correlation of levels with Fried's frailty components of grip strength and walk speed in very old adults, regardless of confounding factors.
161名无认知功能减退的高龄患者（年龄≥80岁）符合分析条件。采用临床和生化数据以及包括双能X线扫描和握力测量在内的身体和认知评估来研究衰弱标准，同时使用高通量流式细胞术评估循环免疫介质（和）。
初步研究发现，与腰臀比和C反应蛋白呈正相关，与血糖呈负相关。在对这些因素进行控制的分析中，握力降低的高龄参与者（OR = 3.299；95% CI 1.08 - 6.09；P = 0.032）以及步行速度较慢的参与者（OR = 2.460；95% CI 1.16 - 7.05；P = 0.022）的血清白细胞介素-6水平相对升高。
我们的研究表明，在高龄成年人中，无论存在混杂因素如何，白细胞介素-6水平与弗里德衰弱标准中的握力和步行速度成分呈强烈负相关。
