Working at height has always been considered as one of the most dangerous industrial activities. Workers' fitness including their physical and psychological ability plays a key role in prevention of occupational accidents. This research was conducted to investigate the physical and mental fitness of telecommunication tower climbers as well as their job stress.
This cross-sectional study was conducted among employees of a contracting company which worked in the field of telecommunication tower installation in Iran during 2016. Sixty out of 93 workers voluntarily participated in this study. Data collection tools were the Persian version of the Work Ability Index (WAI), the Persian version of the Health and Safety Executive (HSE) Stress Indicator Tool and an author-developed measure to assess socio-demographic characteristics. Data was analyzed through statistical tests such as independent t-test, univariate analyses of variance (ANOVAs), Pearson's correlation coefficient, and multivariate linear regression; using SPSS 19 software.
Workers' mean ± SD WAI score was 29.17 ± 10.33 and for work-related stress was 3.08 ± 1.80. There was a significant relation between WAI and educational level, job tenure, hours of sleep per day, regular exercise, and second job. The repression modeling explained 67.4% of the total variance (adjusted R2) of the WAI score. Among the dimensions of work related stress, control (β= 0.21) and changes (β= -0. 40) were significant predictors of the WAI score.
To improve the worker's work ability, intervention programs should focus on promoting level of job control, sleep quality and exercise. Additionally, implementing a comprehensive macroergonomics and participatory program for increase involvement the workers in organization changes should be considered.
高处作业一直被视为最危险的工业活动之一。工人的健康状况，包括其身体和心理能力，在预防职业事故中起着关键作用。本研究旨在调查电信塔攀爬工人的身心健康状况以及他们的工作压力。
本横断面研究于2016年在伊朗一家从事电信塔安装领域的承包公司员工中进行。93名工人中有60名自愿参与了本研究。数据收集工具包括波斯语版的工作能力指数（WAI）、波斯语版的健康与安全执行局（HSE）压力指标工具以及作者自行编制的用于评估社会人口学特征的量表。数据通过独立t检验、单因素方差分析（ANOVA）、Pearson相关系数和多元线性回归等统计检验进行分析；使用SPSS 19软件。
工人的平均±标准差WAI评分为29.17±10.33，工作相关压力评分为3.08±1.80。WAI与教育水平、工作年限、每日睡眠时间、定期锻炼和兼职工作之间存在显著关系。回归模型解释了WAI评分总方差（调整R2）的67.4%。在工作相关压力的维度中，控制（β=0.21）和变化（β=-0.40）是WAI评分的显著预测因素。
为提高工人的工作能力，干预项目应侧重于提高工作控制水平、改善睡眠质量和加强锻炼。此外，应考虑实施全面的宏观工效学和参与式项目，以增加工人对组织变革的参与度。
