A longitudinal panel study.
The aim of this study was to examine the occurrence of low back pain (LBP), especially the association of previous LBP with further episodes of LBP, in survivors of the Great East Japan Earthquake (GEJE) during the course of 5 years.
LBP is common among survivors of natural disasters, but its long-term course is not clear.
A 5-year longitudinal study was conducted among survivors of the GEJE (n = 1821). The presence of LBP was assessed using a self-reported questionnaire at 2, 4, and 7 years after the disaster (termed the first, second, and third time points, respectively). Multiple logistic regression analysis was performed to assess a potential association between LBP at the first and second time points with LBP at the third time point, and the odds ratios (ORs) and 95% confidence intervals (CI) were calculated.
The prevalence of LBP was 25.3%, 27.3%, and 27.2% at the first, second, and third time points, respectively. The occurrence of LBP at the first time point was significantly associated with LBP at the third time point, and the adjusted odds ratio (OR) (95% confidence interval [CI]) was 5.47 (4.28-6.98). Furthermore, LBP at the first and second time points was significantly associated with LBP at the third time point. Compared to no LBP at the first and second time points, the adjusted OR (95% CIs) for LBP at the third time point was 4.12 (3.14-5.41) in the case of LBP at either of the first or second time points and 10.73 (7.80-14.76) for LBP at both time points (P for trend < 0.001).
Previous LBP was associated with LBP 5 years later among survivors of the GEJE. Furthermore, the effect on subsequent LBP was stronger with a higher frequency of previous LBP episodes.Level of Evidence: 3.
一项纵向队列研究。
本研究旨在调查东日本大地震（GEJE）幸存者在5年期间下腰痛（LBP）的发生情况，尤其是既往LBP与后续LBP发作之间的关联。
LBP在自然灾害幸存者中很常见，但其长期病程尚不清楚。
对GEJE幸存者（n = 1821）进行了一项为期5年的纵向研究。在灾难发生后的第2年、第4年和第7年（分别称为第一、第二和第三个时间点）使用自我报告问卷评估LBP的存在情况。进行多因素逻辑回归分析，以评估第一和第二个时间点的LBP与第三个时间点的LBP之间的潜在关联，并计算比值比（OR）和95%置信区间（CI）。
在第一、第二和第三个时间点，LBP的患病率分别为25.3%、27.3%和27.2%。第一个时间点的LBP发生与第三个时间点的LBP显著相关，调整后的比值比（OR）（95%置信区间[CI]）为5.47（4.28 - 6.98）。此外，第一和第二个时间点的LBP与第三个时间点的LBP显著相关。与第一和第二个时间点均无LBP相比，在第一或第二个时间点有LBP的情况下，第三个时间点LBP的调整后OR（95% CIs）为4.12（3.14 - 5.41），两个时间点均有LBP时为10.73（7.80 - 14.76）（趋势P < 0.001）。
在GEJE幸存者中，既往LBP与5年后的LBP相关。此外，既往LBP发作频率越高，对后续LBP的影响越强。证据级别：3级。
