According to the Global Burden of Disease, in 2019, approximately 1.71 billion people worldwide were affected by musculoskeletal problems. However, studies investigating the association between work duration and Body Mass Index (BMI) with MSD complaints in the manufacturing industry, particularly in developing countries that still rely heavily on labor-intensive systems, remain limited. This study aims to examine the relationship between work duration and BMI with MSD complaints among workers in the manufacturing industry.</span></i></span></span></span><br> <span style="font-size:11pt"><span style="text-justify:inter-ideograph"><span style="font-family:&quot;Times New Roman&quot;,serif"><i><span style="font-size:12.0pt">Methods: A cross-sectional analytical study was conducted involving 109 manufacturing workers in the production department. Data were collected subjectively through interviews using the Nordic Body Map questionnaire and anthropometric measurements to calculate BMI. The relationship between variables was analyzed using the Chi-Square test with a significance level of &alpha; = 0.05.</span></i></span></span></span><br> <span style="font-size:11pt"><span style="text-justify:inter-ideograph"><span style="font-family:&quot;Times New Roman&quot;,serif"><i><span style="font-size:12.0pt">Results: The study found that the majority of workers had normal work duration or less than 8 hours per day (83.5%), were classified as overweight (58.7%), and reported moderate MSD complaints (58.7%). A significant correlation was found between BMI and MSD complaints (p = 0.017), while no significant correlation was found between work duration and MSD complaints (p = 0.717).</span></i></span></span></span><br> <span style="font-size:11pt"><span style="text-justify:inter-ideograph"><span style="font-family:&quot;Times New Roman&quot;,serif"><i><span style="font-size:12.0pt">Conclusion: It can be concluded that BMI has a significant correlation with MSD complaints among manufacturing workers. Interventions should focus on weight control, including promoting balanced nutritional intake. However, other potential risk factors such as lifestyle habits, demographic characteristics, and workload should also be considered in future studies.</span></i></span></span></span></div> Body mass index,Work duration,MSDs,Workers in the,manufacturing industry 36 46 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-3259-1&slc_lang=en&sid=1 Noeroel Widajati noeroel.widajati@fkm.unair.ac.id 1800319475328460014298 1800319475328460014298 Yes Department of Occupational Health and Safety, Faculty of Public Health, Universitas Airlangga, Indonesia Adellian Nugraha adelliannugraha@fkm.unair.ac.id 1800319475328460014299 1800319475328460014299 No Department of Occupational Health and Safety, Faculty of Public Health, Universitas Airlangga, Indonesia Ng yee guan shah86zam@upm.edu.my 1800319475328460014300 1800319475328460014300 No Occupational Safety and Health,Dept. of Environmental & Occupational Health, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Malaysia.
