O-408 Factors Associated With Musculoskeletal Disorders Among Informal Cleaning Staff in a University in Southwest Nigeria

Introduction Work related Musculoskeletal disorders (MSDs) remain a significant work-Public Health concern globally, including among cleaning staff due to their high-risk tasks and often strenuous work conditions. This study assessed factors associated with work-related MSDs among cleaners in a public institution. Methodology A cross-sectional study of 320 informal cleaning staff employed on contract in Obafemi Awolowo University, Ile-Ife, Nigeria was conducted. A semi-structured questionnaire with questions adapted from the Nordic musculoskeletal questionnaire was used to obtain Information on socio-demographics, work practices and prevalence/sites of MSD. Data were analyzed using the SPSS version 25 and p< 0.05 was considered significant. Results Majority (238; 74.4%) of respondents were aged 40-60 years and most (298; 93.1%) were females. Most respondents (280; 87.5%) earned < $40 monthly and 273 (85.3%) had worked for ≤ 10years. The commonly used PPE were hand gloves (89.7%) and nose mask while 98.1% and 99.4% of respondents have never used waterproof apron or safety goggles respectively. A majority (88.1%) worked 6-8 hours daily, with 99.1% in a bent position and 83.4% stood for >2hours at a time. In the past 7 days, common MSD-affected sites were lower back (35.9%), knees (23.1%), hips/thighs (15.9%), and right shoulder (15.6%). Significant factors associated with MSD included age >60 years, no formal education, lack of prior safety training and being overweight/obese. Conclusion The study highlighted a significant MSD burden among cleaning staff. We recommend that employers should implement interventions like ergonomics and safety training as well as regular health screenings to reduce MSD burden and promote cleaners’ well-being.
