Abstract

Purpose: The benefits of leisure-time physical activity (LTPA) in reducing mortality are well-known, while the relationship between work-related physical activity (WRPA) and mortality remains controversial. The study aimed to investigate the association between WRPA and mortality, and to determine whether LTPA should be recommended in a population with a high level of WRPA.

Method: Data were obtained from a sample of adults aged 20-80 years included in the National Health and Nutrition Examination Survey (NHANES) cohort from 2007 to 2018. Hazard ratios (HRs) for the association between WRPA and all-cause mortality were estimated using Cox proportional regression models. All analyses were performed in accordance with NHANES guidelines, in which data were complex-weighted first and then analyzed in the next step, Statistical significance was defined as a two-sided P-value < 0.05.

Results: A total of 27,567 participants were included in the study. Over a median follow-up period of 78 months, a total of 2,553 (weighted ratio, 6.5%) participants were assumed dead. The mean age (SD) of this cohort was 47.5 (16.7), and 48.5% were men. Compared to participants without WRPA (as the reference group), participants engaged in WRPA exhibited a significantly reduced risk of all-cause mortality over different time periods. Specifically, the HR for participants with less than 17.5 h of weekly participation were 0.70 (95% CI: 0.62-0.78). For those participating between 17.5 and 35 h per week, the HR was 0.80 (95% CI: 0.64-1.00), while participants engaging in more than 35 h of weekly participation had an HR of 0.71 (95% CI: 0.56-0.91).

Conclusions: WRPA is a protective factor that reduces the risk of all-cause death, especially in people without LTPA.

美国队列中与工作相关的体育活动与死亡率之间的关系。

目的：闲暇时间体育锻炼（LTPA）对降低死亡率的益处众所周知，而与工作相关的体育锻炼（WRPA）与死亡率之间的关系仍存在争议。本研究旨在调查 WRPA 与死亡率之间的关系，并确定是否应向 WRPA 水平较高的人群推荐 LTPA：数据来源于 2007 年至 2018 年美国国家健康与营养调查（NHANES）队列中 20-80 岁的成人样本。采用考克斯比例回归模型估算了WRPA与全因死亡率之间的相关性的危险比（HRs）。所有分析均按照NHANES指南进行，即首先对数据进行复合加权，然后在下一步中进行分析，统计显著性定义为双侧P值结果：共有 27,567 名参与者参与了研究。在 78 个月的中位随访期内，共有 2553 人（加权比例为 6.5%）被认为死亡。该群体的平均年龄（SD）为 47.5（16.7）岁，48.5% 为男性。与未参与 WRPA 的参与者（参照组）相比，参与 WRPA 的参与者在不同时期的全因死亡风险均显著降低。具体来说，每周参与时间少于 17.5 小时的参与者的 HR 为 0.70（95% CI：0.62-0.78）。每周参与 17.5 至 35 小时的参与者的 HR 为 0.80（95% CI：0.64-1.00），而每周参与 35 小时以上的参与者的 HR 为 0.71（95% CI：0.56-0.91）：结论：WRPA是一种保护性因素，可降低全因死亡的风险，尤其是对没有LTPA的人而言。

期刊介绍： International Archives of Occupational and Environmental Health publishes Editorials, Review Articles, Original Articles, and Letters to the Editor. It welcomes any manuscripts dealing with occupational or ambient environmental problems, with a special interest in research at the interface of occupational health and clinical medicine. The scope ranges from Biological Monitoring to Dermatology, from Fibers and Dust to Human Toxicology, from Nanomaterials and Ultra-fine Dust to Night- and Shift Work, from Psycho-mental Distress and Burnout to Vibrations. A complete list of topics can be found on the right-hand side under For authors and editors. In addition, all papers should be based on present-day standards and relate to: -Clinical and epidemiological studies on morbidity and mortality -Clinical epidemiological studies on the parameters relevant to the estimation of health risks -Human experimental studies on environmental health effects. Animal experiments are only acceptable if relevant to pathogenic aspects. -Methods for studying the topics mentioned above.
