title: An epidemiological study of low back pain among oil drilling workers in India.
abstract: Many episodes of low back pain are disabling, thus making it one of the costly occupational health problem. The proper alignment and lifting operations during drilling process frequently exposed the oil-drilling workers to unusual strain on the spine and thus make them susceptible for developing low back pain. The present cross-sectional study was carried out in 71 oil-drilling workers. The prevalence of self-reported low back pain was found to be 29.6%. Higher prevalence was found in those working in awkward working posture (c 2 = 6.41; df = 1; p < 0.01). No other factors, namely, age, obesity, duration of exposure, smoking habit, family history of musculoskeletal disorders, exposure to vibration, lifting of weights and past history of injury was found to be statistically significant. Furthermore, using univariate and multivariate analysis, none of the factor was found to have excess risk of occurrence of low back pain, which can partly be attributed to small sample size.
