Work-related musculoskeletal disorders among Pakistani construction workers: Prevalence, characteristics, and associated risk factors

BACKGROUND: Worldwide, approximately 350 million people are currently employed in the construction industry. OBJECTIVE: To determine the prevalence, pain characteristics, and associated risk factors for musculoskeletal disorders (MSDs) among construction workers in Pakistan. METHODS: This study was a cross-sectional survey conducted from February to August 2019 among 666 construction workers. The data were collected using a questionnaire consisting of 4 sections: demographic information, a numerical pain intensity rating scale, a Nordic questionnaire to report prevalence, and pain characteristics. SPSS was used for data entry and analysis. RESULTS: The mean age of the construction workers was 34.49 years. Participants who reported pain were 397 out of 666 and 269 were those who reported no pain. The 12-month prevalence of pain among construction workers in more than one body area was 89% (n = 591) and the 7-day prevalence was 52% (n = 343); lower back pain was the most common type of pain with a 12-month prevalence of 27% (n = 180) and a 7-day prevalence of 17% (n = 112). Regarding the characteristics of the pain, 26% (173) of the workers suffered pain occasionally, 27% (180) participants had pain for <= 2 hours per day, and 32.9% (219) had dull pain. Moreover, a significant relationship was found (p < 0.05) between MSDs and age, lifestyle, work experience, smoking habits, and absence from work. CONCLUSION: Musculoskeletal pain is highly prevalent, with lower back pain being the most commonly reported type. Absence fromwork and disability in performing normal daily activities have been reported as consequences of musculoskeletal pain. Moreover, this study underscores the importance of targeted preventive healthcare measures for construction workers.

Automated summary

This study investigated the prevalence, pain characteristics, and associated risk factors for musculoskeletal disorders among construction workers in Pakistan. Lower back pain was found to be the most common type of pain. The study highlights the importance of targeted preventive healthcare measures for construction workers, as musculoskeletal pain can lead to absence from work and disability in performing normal daily activities.
