The manifestation of muscle dysfunction associated with diabetes is commonly observed in skeletal muscles. The negative effect of hyperglycemia on muscle function is systemic and it may extend to abdominal muscles. Hence, the purpose of this study was to determine whether hand grip strength (HGS), an indicator of peripheral muscle strength, correlates with peak expiratory flow (PEF), which reflects the strength of abdominal muscles, among middle-aged and older Chinese individuals with diabetes. After controlling for all variables except for physical activity, 10 L/min increase in PEF was associated with 0.2 kg increase in HGS (β = .02, p < .0001). In the model additionally controlling for physical activity, the effect size of PEF on HGS did not change (β = .02, p < .0001). Our results suggest that among individuals with diabetes, PEF is positively related to HGS. The relationship may suggest a decline in PEF and a weakness of abdominal muscles.
与糖尿病相关的肌肉功能障碍表现常见于骨骼肌。高血糖对肌肉功能的负面影响是全身性的，可能会扩展到腹部肌肉。因此，本研究的目的是确定在患有糖尿病的中国中老年人中，作为外周肌肉力量指标的握力（HGS）是否与反映腹部肌肉力量的呼气峰值流速（PEF）相关。在控制了除身体活动外的所有变量后，PEF每增加10 L/min，HGS增加0.2 kg（β = 0.02，p < 0.0001）。在额外控制身体活动的模型中，PEF对HGS的效应大小没有变化（β = 0.02，p < 0.0001）。我们的结果表明，在糖尿病患者中，PEF与HGS呈正相关。这种关系可能表明PEF下降和腹部肌肉无力。
