Effect of Back Pain on Occupational Stress among White-collar Workers

Introduction and purpose: The prevalence of musculoskeletal disorders in&nbsp;stressful jobs is very high. The people suffering from these disorders have low&nbsp;decision-making ability and perceived social support, while they have high&nbsp;physical and psychological job requirements. Regarding this, the present study&nbsp;was conducted with the aim of investigating the effect of waist and back pain on&nbsp;occupational stress.&nbsp;Methods: This descriptive cross-sectional study was conducted on 89 employees&nbsp;of Abadan Ports and Marine Administration in 2016. The study population was&nbsp;selected through random sampling method. The data were collected using Health&nbsp;and Safety Executive Management Standards Indicator and Body Discomfort&nbsp;Chart. Data analysis was&nbsp; performed using descriptive (i.e., frequency andpercentage) and inferential statistics (i.e., t-test) in SPSS version 18.&nbsp;Results: According to the findings, 50% and 31% of the participants had&nbsp;experienced waist and back pain, respectively. The highest and lowest stress&nbsp;levels in this study were related to role (77%) and communication (2.32%),&nbsp;respectively. The results of the t-test revealed a significant difference between&nbsp;the people with waist pain and those without such pain in terms of peer support,&nbsp;role, communication, and variations (P<0.05).&nbsp;Conclusion: As the findings of the present study indicated, back pain and stress&nbsp;had high prevalence among the white-collar workers. Back pain can be an effective&nbsp;factor on the stress level of the office workers

بررسی ارتباط بین وقوع حوادث با شاخص توانایی انجام کار و عملكرد سيستم تنفسي: مطالعه موردی در یک صنعت تولید تجهیزات نیروگاهی

Background and Aim: The nature of machining jobs has classified it as one of the special, dangerous, and important jobs. The ability to do this job, in addition to having the necessary knowledge and skills, requires acceptable physical, physical, and mental performance of people. Therefore, the present study was conducted with the aim of investigating the relationship between the occurrence of accidents with the work ability index and respiratory performance in a power plant equipment manufacturing industry. Methods: The present study was conducted on 142 machine workers. In order to collect data, researcher-made demographic-occupational information questionnaires and workability indexes were used. A pulmonary function test was performed with a spirometry device based on the standards of the American Thoracic Society. In order to analyze the data, SPSS21 statistical software was used. Results: The study samples' mean WAI was in the good category (37-44). The results of respiratory function&nbsp; (% FEV1 / FVC) in the workers with more than five years of experience showed that an average of 95.8% of the study population had a respiratory function of below 85%. The mean number of occupational accidents was 65.9% of the study population was reported to have equal to or less than three accidents. In the study sample, the average accident severity (days lost) was 94.5% of the population had equal to or less than nine days lost due to the accidents. The relationship between the WAI, respiratory system function, and occupational accidents was significant (p &lt; 0.05). Conclusion: The Work Ability Index in the machinery workers was within a reasonable range, and the number and severity of their occupational accidents were low. Further studies should be conducted on these indicators and respiratory function. Also, it is recommended that the workability be examined during the pre-employment process and the results are applied in the human resources management.
