Grip muscle force has always been used to assess functional limitations in elderly. Its use as a tool to assess work capacity has never been described in the literature.
To describe the patent determinants of grip strength and the usefulness of its measurement in assessing workability index in the healthcare sector.
This is a cross-sectional study conducted in a sample of 293 healthcare workers representative of 1181 based on a comprehensive questionnaire about socio-professional characteristics and on an 8-item work capacity evaluation (WAI). Besides, Body mass index was measured and muscle strength was assessed by JAMAR hydraulic dynamometer.
Handgrip Strength was stronger in male nurses (p < 0.001), with low perceived physical load (p = 0.0001) and working on a night shift (p = 0.001). It decreased with a greater duration of household work (p < 0.0001) and increased with a greater BMI (p = 0.015) and a better workability index (p < 0.0001). After removal of all the variables that were not independently associated with the muscle strength force, factors accounting for 52.6% of the variance in nurses handgrip strength were gender (p < 0.001), workability index (p < 0.001), duration of household work (p = 0.021), BMI (p = 0.002), perceived physical load (p < 0.001) and work schedule (p = 0.002).
Grip Strength Test is a useful tool to assess strength and functional capacity at work in healthcare workers. Further longitudinal studies are required to confirm this hypothesis.
握力一直被用于评估老年人的功能受限情况。而其作为评估工作能力的工具在文献中从未被描述过。
描述握力的决定因素及其测量在评估医疗保健部门工作能力指数方面的实用性。
这是一项横断面研究，对293名医护人员进行了抽样，这些人员代表了1181名医护人员。研究基于一份关于社会职业特征的综合问卷以及一项8项工作能力评估（WAI）。此外，测量了体重指数，并通过JAMAR液压测力计评估了肌肉力量。
男护士的握力更强（p < 0.001），感知到的身体负荷较低（p = 0.0001）且值夜班（p = 0.001）。握力随着家务劳动时间的增加而降低（p < 0.0001），随着体重指数的增加（p = 0.015）和工作能力指数的提高（p < 0.0001）而增加。在去除所有与肌肉力量无独立关联的变量后，占护士握力方差52.6%的因素包括性别（p < 0.001）、工作能力指数（p < 0.001）、家务劳动时间（p = 0.021）、体重指数（p = 0.002）、感知到的身体负荷（p < 0.001）和工作时间表（p = 0.002）。
握力测试是评估医护人员工作时力量和功能能力的有用工具。需要进一步的纵向研究来证实这一假设。
