Construction and health care workers have a high prevalence of musculoskeletal disorders, and they are assumed to have physically demanding jobs. Profession- and gender-specific associations between individual capacity and musculoskeletal pain have not been sufficiently investigated. The main aim of this study was to examine the association between individual capacity (maximal oxygen uptake (V̇O) and handgrip strength) and musculoskeletal pain among construction and health care workers.
This cross-sectional study examined 137 construction and health care workers (58 women and 79 men) with a mean age of 41.8 years (standard deviation 12). Aerobic capacity was indirectly assessed by the Åstrand cycle test, and strength was assessed by a handgrip test. Musculoskeletal pain was described by total pain, divided into neck, shoulder, and low back pain, during the last 12 months, and it was dichotomized in below or above 30 days. Logistic regression was used to analyse the associations between V̇O, strength, and musculoskeletal pain in the total study sample and separately for construction and health care workers. Analyses were adjusted for age, gender, body mass index (BMI), and selected mechanical and psychosocial factors.
Every second participant (51.8%) reported pain in either neck, shoulders or low back for more than 30 days during the last 12 months. Among the health care workers, a small but significant association was found between a high V̇O, high handgrip strength, and a low level of musculoskeletal pain. No association was found for the construction workers.
An association between V̇O handgrip strength, and musculoskeletal pain was found for health care workers but not for construction workers. These results indicate that activities promoting individual capacity may reduce musculoskeletal pain for health care workers.
建筑工人和医护人员肌肉骨骼疾病的患病率很高，且他们的工作被认为对体力要求很高。个体能力与肌肉骨骼疼痛之间的职业和性别特异性关联尚未得到充分研究。本研究的主要目的是检验建筑工人和医护人员的个体能力（最大摄氧量（V̇O）和握力）与肌肉骨骼疼痛之间的关联。
这项横断面研究对137名建筑工人和医护人员（58名女性和79名男性）进行了检查，他们的平均年龄为41.8岁（标准差12）。通过阿斯兰德循环测试间接评估有氧能力，通过握力测试评估力量。肌肉骨骼疼痛通过过去12个月内的总疼痛来描述，分为颈部、肩部和下背部疼痛，并将其分为30天以下或以上进行二分法分析。使用逻辑回归分析整个研究样本以及分别针对建筑工人和医护人员的V̇O、力量与肌肉骨骼疼痛之间的关联。分析对年龄、性别、体重指数（BMI）以及选定的机械和社会心理因素进行了调整。
在过去12个月中，每两名参与者中就有一名（51.8%）报告颈部、肩部或下背部疼痛超过30天。在医护人员中，发现高V̇O、高握力与低水平的肌肉骨骼疼痛之间存在小但显著的关联。建筑工人中未发现关联。
医护人员中发现V̇O、握力与肌肉骨骼疼痛之间存在关联，但建筑工人中未发现。这些结果表明，促进个体能力的活动可能会减轻医护人员的肌肉骨骼疼痛。
