Prevelance of Low Back Pain and its Association with the Thigh Holster use Among Police Officers -A Cross Sectional Survey

Abstract

Background: Low back pain (LBP) occurs in 60–90% of individuals throughout their lifetime and is the second most prevalent clinical complaint. Approximately 37% of these cases are work-related, resulting in severe disability and absenteeism. Military police officers are particularly exposed because of long shifts and heavy equipment, placing added spinal strain on them. Ergonomic problems also contribute to LBP hazard. This research examines the prevalence of LBP, its associated factors, and ergonomic determinants employing the VAS to facilitate prevention and lessening economic burdens.
Objective: The study evaluate the prevalence of low back pain and evaluate the association between the thigh holster use and low back pain in police officers Also includes other occupational factors and lifestyle habits that cause severity of low back pain among active-duty police officers.
Methodology: The cross-sectional study was involve active-duty police officers in Karachi, selected through non probity convenient sampling from various police stations. Data on demographics, occupational factors (service duration, duty hours, and holster use), and lifestyle habits were collected using a standardized questionnaire. The presence and severity of low back pain were recorded, through VAS scale. Informed consent was obtained from all participants. Data was analyzed to determine the association between prolonged thigh holster use and the occurrence and severity of low back pain.
Result: This study analysised 127 Karachi Special Security Unit police officers and found a high prevalence of low back pain (67.7%), particularly among those with long service and physically demanding field duties. Thigh holsters were the most commonly used and worn for the longest duration, leading to greater biomechanical strain. Officers using thigh holsters showed significantly higher LBP prevalence (79.1%) and greater pain severity compared to other holster types. Statistical tests confirmed a significant association between thigh holster use and low back pain, highlighting the need for ergonomic interventions.
Conclusion: The survey demonstrates a strong association between the use of thigh holsters and increased frequency, severity, and disability of low back pain among active-duty police officers in Karachi, highlighting duty gear as a significant modifiable risk factor. These findings emphasize the need for ergonomically informed equipment policies to reduce preventable pain, improve officer well- being, and support long-term operational effectiveness.
