DESCRIPTION (provided by applicant): With the aging of the American workforce, the largest percentage increase in employment is occurring in the 55-64 year old age group. This research is designed to assess effects of workplace biomechanical, psychosocial, organizational and non-workplace factors on normal age related changes in musculoskeletal function and performance. There are particular emphases on the role of gender and on identifying sub- populations that may be at increased risk of exceeding age expected changes in musculoskeletal function and performance. We use the term musculoskeletal health (MSH) to define the complex of physiological performance and effective function. An estimated 1200-1400 workers representing both genders, and meeting a broad age demographic, will be studied in Connecticut manufacturing facilities. Their evaluation will include questionnaires that survey individual, organizational and psychosocial factors; direct measures of physical performance, strength and muscle power; and instrumented and observed exposure measurement. There are cross-sectional and longitudinal components employed in a mixed design that accommodates the relatively short study period, and the longer time span of many health outcomes relevant to the musculoskeletal system. A key aspect of this study is the influence of the so-called "healthy worker survivor effect", the extent to which musculoskeletal symptoms and function influence withdrawal from the workforce. This is addressed through several imputative models. We will also estimate the interactive effect of risk factors (extrinsic and intrinsic) on the distribution of subjective and objective findings and undertake the compilation of broader indices of MSH.

描述（由申请人提供）：随着美国劳动力的老龄化，就业率增幅最大的是 55-64 岁年龄组。本研究旨在评估工作场所生物力学、心理社会、组织和非工作场所因素对正常年龄相关的肌肉骨骼功能和表现变化的影响。特别强调性别的作用以及确定肌肉骨骼功能和性能变化可能超过年龄预期变化的风险增加的亚人群。我们使用肌肉骨骼健康 (MSH) 一词来定义生理表现和有效功能的复合体。据估计，康涅狄格州的制造工厂将研究 1200-1400 名男女工人，并满足广泛的年龄人口需求。他们的评估将包括调查个人、组织和心理社会因素的问卷；直接测量身体表现、力量和肌肉力量；并使用仪器和观察暴露测量。混合设计中采用了横截面和纵向成分，以适应相对较短的研究周期以及与肌肉骨骼系统相关的许多健康结果的较长时间跨度。这项研究的一个关键方面是所谓的“健康工人幸存者效应”的影响，即肌肉骨骼症状和功能影响退出劳动力市场的程度。这是通过几个推定模型来解决的。我们还将估计风险因素（外在和内在）对主观和客观结果分布的交互影响，并编制更广泛的 MSH 指数。
