Background: Data pertaining to risk factors of nonspecific low back pain (NSLBP) among rural Bangladeshi is scarce. This study explored the risk factors associated with NSLBP among rural Bangladeshi adults. Methods: A community-based study was done in Sonargaon Upazila of Narayanganj district of Bangladesh. A total of 343 NSLBP patients were recruited as cases, based on the Bangla version of Community oriented program for control of rheumatic diseases (COPCORD) questionnaire. An equal number of age and sex matched subjects without any rheumatic disease were recruited from the same community. A total of 15 probable factors were analyzed. Age-sex adjusted univariate and age-sex with 13 risk factors adjusted multivariate conditional logistic regression analyses were done. Results: The mean age of the participants was 33.1 years old (standard deviation: 9.5). Out of 13 risk factors, history of chronic disease (OR 2.0, 95% CI 1.2 – 3.4), prolonged sitting (OR 4.6, 95% CI 2.0 – 11.0), squatting (OR 7.2, 95% CI 3.2 – 16.0), bending of the waist (OR 3.7, 95% CI 1.8 – 7.6), regular lifting or carrying a heavy load (OR 9.2, 95% CI 2.2 – 39.7), prolonged standing (OR 5.8, 95% CI 1.9 – 17.7), occupation related to strenuous physical activity (OR 0.2, 95% CI 0.1 – 0.8), overweight (body mass index >=25 kg/m2) (OR 3.1, 95% CI 1.8 – 5.2) and depression (OR 2.2, 95% CI 1.4 – 3.6) were found to be significantly associated with NSLBP. Conclusions: The study generated knowledge on associated risk factors for NSLBP in rural people of Bangladesh that may facilitate an evidence-based intervention for the target group.
