Prevalence of Low Back Pain among Public High School Teachers in the City of Manila

Abstract

Objectives: To determine the prevalence of low back pain (LBP) among public high school teachers in the City of Manila and contributing factors leading to LBP. Methodology: A cross-sectional observational study was conducted at the five largest public high schools in the City of Manila. Five hundred eighteen teachers were given questionnaires on specific working patterns of teachers which include questions on demographics, psychosocial status, job satisfaction, socioeconomic status, and working hours per day. Modified Oswestry Disability Questionnaire was also given to determine how LBP affected their ability to manage everyday life. Results: Fifty three percent of 379 public high school teachers presented with LBP. Stress level (odds ratio=4.15) & increased working hours (5-6 hours OR=1.9; 7-8 hours OR =2.5) showed significant risks for LBP. Smoking (OR=1.38) and alcohol consumption (OR=1.01) showed weak correlation with LBP. Discussion: Level of stress reflects the teachers' increased risk for acquiring LBP secondary to exposure to fatigue, work environment and the satisfaction on their job. Daily working hours also posed greater risk for LBP as teachers are more exposed to prolonged and incorrect postures. Conclusions: Stress level and increased worked hours per day are significant risk factors for LBP development among the teachers.
