The accelerated loss of muscle strength and mass observed in older type 2 diabetes mellitus (T2DM) patients due to the combined effects of diabetes and obesity, greatly increases their risk for sarcopenia. Early detection and treatment of probable and confirmed sarcopenia is paramount to delay mobility disability. Using low handgrip strength cut-off points for the initial identification of sarcopenia according to the new European Working Group on Sarcopenia in Older People (EWGSOP2) guidelines may mask the presence of sarcopenia. Relative knee extension strength cut-off points using a simple hand-held dynamometer can assist clinicians in the diagnosis of probable and confirmed sarcopenia by possibly reducing false negative results. A cohort of one hundred T2DM older patients (60% women) (mean age 74.5 years) mostly obese community dwelling older adults were evaluated for body composition by Bioelectrical impedance analysis (BIA), yielding appendicular skeletal mass index (ASMI) results. Patients underwent handgrip strength (HGS) and knee extension strength (KES) tests as well as functional ability tests. Prevalence of probable and confirmed sarcopenia using HGS and KES cut-off points were calculated. Pearson correlations were performed to evaluate the relationship between ASMI and limbs strength. A regression analysis was conducted to examine which variables best predict ASMI values. A multivariate analysis of covariance was performed to assess the effect of independent variables on KES and HGS. Using cutoff points for low KES identified 24 patients with probable sarcopenia and two with confirmed sarcopenia. Conversely, using the EWGSOP2 cut off points for low HGS, identified only one patient with probable sarcopenia and none of the patients with confirmed sarcopenia. KES cut-off points using a simple hand-held dynamometer can assist in the identification of probable and confirmed sarcopenia using EWGSOP2 cut off points for low muscle mass in a population of older T2DM patients for further analysis and early treatment. This is notably true in patients possessing high body mass index (BMI) alongside normal ASMI and HGS, potentially reducing false positive sarcopenia screening results.

膝关节伸展力量测试是否应该作为筛查测试来识别老年 T2DM 患者可能和确诊的肌肉减少症?

由于糖尿病和肥胖症的综合影响,在老年 2 型糖尿病 (T2DM) 患者中观察到的肌肉力量和质量加速损失,大大增加了他们患肌肉减少症的风险。早期发现和治疗可能和确诊的肌肉减少症对于延迟行动障碍至关重要。根据新的欧洲老年人肌肉减少症工作组 (EWGSOP2) 指南,使用低握力截断点来初步识别肌肉减少症可能会掩盖肌肉减少症的存在。使用简单的手持测力计的相对膝关节伸展强度截止点可以通过可能减少假阴性结果来帮助临床医生诊断可能和确诊的肌肉减少症。一百名 T2DM 老年患者(60% 为女性)(平均年龄 74 岁)的队列。5 年)通过生物电阻抗分析 (BIA) 评估大多数肥胖社区居住的老年人的身体成分,得出附肢骨骼质量指数 (ASMI) 结果。患者接受了握力 (HGS) 和膝关节伸展力 (KES) 测试以及功能能力测试。使用 HGS 和 KES 截止点计算了可能和确认的肌肉减少症的患病率。进行 Pearson 相关性以评估 ASMI 与肢体力量之间的关系。进行回归分析以检查哪些变量最能预测 ASMI 值。进行协方差的多变量分析以评估自变量对 KES 和 HGS 的影响。使用低 KES 的截止点确定了 24 名可能患有肌肉减少症的患者和 2 名确认患有肌肉减少症的患者。反过来,使用低 HGS 的 EWGSOP2 截止点,仅确定了一名可能患有肌肉减少症的患者,而没有确定患有肌肉减少症的患者。使用简单的手持测力计的 KES 截止点可以帮助识别可能和确认的肌肉减少症,使用 EWGSOP2 截止点在老年 T2DM 患者群体中低肌肉质量进行进一步分析和早期治疗。在具有高体重指数 (BMI) 以及正常 ASMI 和 HGS 的患者中尤其如此,这可能会减少假阳性肌肉减少症筛查结果。ClinicalTrials.gov PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。仅发现一名可能患有肌肉减少症的患者,而没有一名患者确诊患有肌肉减少症。使用简单的手持测力计的 KES 截止点可以帮助识别可能和确认的肌肉减少症,使用 EWGSOP2 截止点在老年 T2DM 患者群体中低肌肉质量进行进一步分析和早期治疗。在具有高体重指数 (BMI) 以及正常 ASMI 和 HGS 的患者中尤其如此,这可能会减少假阳性肌肉减少症筛查结果。ClinicalTrials.gov PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。仅发现一名可能患有肌肉减少症的患者,而没有一名患者确诊患有肌肉减少症。使用简单的手持测力计的 KES 截止点可以帮助识别可能和确认的肌肉减少症,使用 EWGSOP2 截止点在老年 T2DM 患者群体中低肌肉质量进行进一步分析和早期治疗。在具有高体重指数 (BMI) 以及正常 ASMI 和 HGS 的患者中尤其如此,这可能会减少假阳性肌肉减少症筛查结果。ClinicalTrials.gov PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。使用简单的手持测力计的 KES 截止点可以帮助识别可能和确认的肌肉减少症,使用 EWGSOP2 截止点在老年 T2DM 患者群体中低肌肉质量进行进一步分析和早期治疗。在具有高体重指数 (BMI) 以及正常 ASMI 和 HGS 的患者中尤其如此,这可能会减少假阳性肌肉减少症筛查结果。ClinicalTrials.gov PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。使用简单的手持测力计的 KES 截止点可以帮助识别可能和确认的肌肉减少症,使用 EWGSOP2 截止点在老年 T2DM 患者群体中低肌肉质量进行进一步分析和早期治疗。在具有高体重指数 (BMI) 以及正常 ASMI 和 HGS 的患者中尤其如此,这可能会减少假阳性肌肉减少症筛查结果。ClinicalTrials.gov PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。政府 PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。政府 PRS:NCT03560375。最后注册日期(最后更新):06/06/2018。该试验是在实际招募受试者之前先验注册的。
