Exploring Musculoskeletal Complaints in a Needle Manufacturing Industry: A Cross-Sectional Study.

Area of Science:

• Occupational Health
• Epidemiology
• Ergonomics

Background:

• Musculoskeletal disorders (MSDs) represent a significant occupational health challenge in Portugal.
• Work-related MSDs (WMSDs) are particularly prevalent, necessitating targeted investigations within specific industries.

Purpose of the Study:

• To determine the prevalence of MSD complaints among workers in a Portuguese needle manufacturing industry.
• To identify specific body parts most affected and associated risk factors, including demographics and job roles.

Main Methods:

• A cross-sectional study involving 526 workers from five departments.
• Utilized sociodemographic questionnaires and the Nordic Musculoskeletal Questionnaire (NMQ).
• Analyzed data for gender, age, Body Mass Index (BMI), occupation, and affected body parts.

Main Results:

• The lower back (54.2%), neck (42.2%), and shoulders (39.0%) were the most frequently reported complaint areas.
• Females reported higher complaint frequencies than males, except for ankles/feet.
• Tuners exhibited the highest complaint rates, with age and occupation identified as significant predictors.

Conclusions:

• Findings highlight the need for gender-, age-, and job-specific ergonomic interventions in manufacturing settings.
• The study underscores the importance of addressing WMSDs through tailored workplace strategies.
