Association between Body Mechanics and Perceived Musculoskeletal Problems among Construction Workers of Udupi District, Karnataka, India: A Cross-sectional Survey.

Background and Objectives: Construction workers are prone to develop musculoskeletal problems and it is a leading cause for the morbidity due to their work type. This study aimed to assess the body mechanics practice and perceived musculoskeletal problems of construction workers. Methods: A cross-sectional survey was conducted between November 2019 and July 2020 among 390 construction workers at construction sites under selected villages of Udupi District, Karnataka by using by proportionate method. Villages were selected using a simple random sampling method and samples were collected by convenience sampling. Samples were mason helpers between 20 and 50 years of age, without any history of chronic musculoskeletal problems. Tools used were demographic proforma, self-reported body mechanics practice questionnaire, and modified Nordic musculoskeletal questionnaire. Analysis done with descriptive and inferential statistics by using SPSS Version 16.0. Results: Majority 144 (36.9%) of the participants were in the age group between 41 and 50 years. Most 376 (96.4%) of them were men and majority of them 309 (79%) followed fair body mechanics practice and 191 (49%) of the participants had low back problems and were responsible for their activity restrictions. Body mechanic practice of the construction workers was found to be significantly associated with unhealthy practice (P ≤ 0.001) and health problems (P < 0.001). Conclusion: The study concluded that the body mechanic practice of the construction workers was found to be significantly associated with unhealthy practices and health problems. The study recommends that educating construction workers about the importance of following proper body mechanics at the workplace and during day-to-day activities is crucial to prevent musculoskeletal problems and improve quality of life.
