摘要

目的:体育活动悖论认为职业体育活动(OPA)是危险的,而休闲体育活动(LTPA)对健康有益。然而,对OPA和LTPA对心血管危险因素的急性影响的研究很少。本研究的目的是调查清洁工在工作和休闲时间每小时走一步对动态血压(ABP)的急性影响。方法:数据来自丹麦91名清洁工的集群随机工地干预,包括问卷、客观身体测量、ABP(在24小时内测量)和步数/小时(在工作和休闲时间测量)。初步的线性回归分析是作为一个混合模型进行的,包括随机截距和斜率,考虑到参与者内部和参与者之间的可变性。我们对性别、年龄、工作资历、药物使用、吸烟、自我报告的健康状况和BMI进行了调整。ABP(mmHg)的变化是每100步/小时估计的。结果:在工作或休闲期间所走的步数与ABP无关。此外,暴露于工作中所采取的步骤之间的ABP似乎没有差异(收缩压-0.42 mmHg,95%置信区间(CI):-1.10-0.25,舒张压-0.03 mmHg,95%CI,-0.45-0.39)和休闲时间(收缩压-0.47mmHg,95%CI,-1.66-0.72,舒张压0.25mmHg,95%CI,-0.46-0.97)。这些促进不同结果的机制需要进一步研究,以提高对体育活动悖论的理解。

The association between number of steps and the ambulatory blood pressure during leisure vs. work hours among cleaners.

The association between number of steps and the ambulatory blood pressure during leisure vs. work hours among cleaners.

Purpose: The physical activity paradox states occupational physical activity (OPA) to be hazardous and leisure time physical activity (LTPA) to be beneficial for health. Yet, the acute effects of OPA and LTPA on cardiovascular risk factors are sparsely investigated. The aim of this study was to investigate the acute effects on ambulatory blood pressure (ABP) from steps/hour during work and leisure time among cleaners.

Methods: Data were obtained from a cluster randomized worksite intervention among 91 cleaners in Denmark and included a questionnaire, objective physical measurements, ABP (measured across 24 h), and steps/hour (measured during work and leisure time). A preliminary linear regression analysis was conducted as a mixed model including random intercept and slope, allowing for both within- and between-participant variability. We adjusted for sex, age, job seniority, medication use, smoking, self-reported fitness and BMI. Changes in ABP (mmHg) were estimated per 100 steps/hour.

Results: The number of steps taken was not associated with ABP during either work or leisure. Moreover, the ABP did not seem to differ between exposure to steps taken during work (systolic - 0.42 mmHg, 95% Confidence Interval (CI): - 1.10-0.25, diastolic - 0.03 mmHg, 95% CI, - 0.45-0.39) and leisure time (systolic -0.47 mmHg, 95% CI, - 1.66-0.72, diastolic 0.25 mmHg, 95% CI, - 0.46-0.97).

Conclusion: Our findings show no significant association between steps/hour and ABP and no contrasting effects between work and leisure time. These mechanisms fostering the divergent results need to be further investigated to improve the understanding of the physical activity paradox.

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.
