Abstract:
Background: Musculoskeletal disorders (MSDs) are a prevalent occupational health issue
among physically active workers, including security guards, due to prolonged standing,
repetitive tasks, and poor ergonomic conditions. These conditions negatively affect quality
of life, productivity, and health outcomes.
Objective: The study aimed to assess the pattern of musculoskeletal conditions among
security guards working in Narayanganj city, Bangladesh, and to examine associations with
demographic and occupational factors such as age, BMI, and working hours.
Methods: A cross-sectional study was conducted with 200 security guards using structured
socio-demographic questionnaires and the standardized Nordic Musculoskeletal
Questionnaire. Data were analyzed using SPSS 25.0 to determine the pattern of
musculoskeletal pain and its association with variables such as age, BMI, and working
hours.
Results: Around 176(88%) out of 200 participants had some type of musculoskeletal pain
in last 12 months. The most common musculoskeletal complaints reported in the last 12
months included lower back pain (24.5%), knee pain (16%), ankle pain (13%), neck pain
(9.5%), and shoulder pain (9%). Age was significantly associated with lower back pain
(p=0.012), knee pain (p=0.001), and ankle pain (p=0.000), while BMI and working hours
showed no significant correlation with MSDs. Most participants were male (89%), aged
25–45 years (57%), and worked more than 8 hours daily (89.5%).
Conclusion: The study highlights a significant burden of MSDs among security guards in
Narayanganj, particularly in the lower back, knees, and ankles. These findings underscore
the need for ergonomic interventions, education, and physiotherapy support to prevent and
manage MSDs in this occupational group. Further research with larger sample sizes is
recommended to generalize findings nationwide.
