Low back pain (LBP) is prevalent among workers both in developed and developing countries. School teachers represent a high proportion of the working population in Malaysia. However, there is a lack of longitudinal study on predictors and course of LBP among teachers. Therefore, this study aimed to determine the predictors and course of LBP among secondary school teachers. Longitudinal data of 701 teachers in Selangor, Malaysia were collected from May 2015 to October 2016. Associations between predictors and LBP were analysed using logistic regression and reported as odds ratio (OR) and 95% confidence interval (CI). At 12-month of follow-up, 44% (95%CI: 40.6%, 48.0%) of the participants reported having LBP. In the regression model that included all risk factors, only LBP at baseline (OR 10.43, 95%CI: 6.19, 17.58) was associated with LBP at 12-month follow-up. When LBP at baseline was removed from the model, anxiety symptom (OR 2.51, 95%CI: 1.19, 5.30) and lifting heavy weights (OR 4.16, 95%CI: 1.40, 12.30) were found to be significantly associated with LBP at 12-month follow-up. In conclusion, issues on anxiety and lifting heavy weights should be addressed to reduce the occurrence of LBP despite the presence of health condition itself (LBP at baseline).
下背痛（LBP）在发达国家和发展中国家的工人中都很普遍。在马来西亚，学校教师在劳动力中占很大比例。然而，关于教师 LBP 的预测因素和病程的纵向研究还很少。因此，本研究旨在确定中学教师的 LBP 预测因素和病程。2015 年 5 月至 2016 年 10 月，在马来西亚雪兰莪州收集了 701 名教师的纵向数据。使用逻辑回归分析预测因素与 LBP 之间的关系，并以比值比（OR）和 95%置信区间（CI）报告。在 12 个月的随访中，44%（95%CI：40.6%，48.0%）的参与者报告有 LBP。在包含所有危险因素的回归模型中，仅基线 LBP（OR 10.43，95%CI：6.19，17.58）与 12 个月随访时的 LBP 相关。当基线 LBP 从模型中去除时，焦虑症状（OR 2.51，95%CI：1.19，5.30）和举重（OR 4.16，95%CI：1.40，12.30）与 12 个月随访时的 LBP 显著相关。总之，尽管存在健康状况本身（基线 LBP），也应解决焦虑和举重问题，以减少 LBP 的发生。
