The Great East Japan Earthquake (GEJE) and Tsunami devastated the northeastern coast of Japan on March 11, 2011. This study attempted to determine whether socio-psychological factors such as sleep disturbance and psychological distress influenced new-onset subjective shoulder pain in survivors, during the post disaster phase of the GEJE. From November 2012 to February 2013 (2 years after the GEJE) and November 2014 to January 2015 (4 years after the GEJE), survivors (18 years old or over) answered self-reported questionnaires. In total, 1,454 survivors responded to the questionnaires and were thus included in this study. New-onset subjective shoulder pain was defined as shoulder pain by encircled response absent at 2 years, and present at 4 years after the GEJE. Two years after the GEJE, ≥ 10/24 points on the Kessler Psychological Distress Scale-6, and ≥ 6/24 points on the Athens Insomnia Scale defined the presence of psychological distress and sleep disturbance, respectively. Multiple logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of the association between new-onset subjective shoulder pain, and psychological distress or sleep disturbance. Amongst participants, 7.2% (105/1,454) reported new-onset subjective shoulder pain. Sleep disturbance was significantly associated with new-onset subjective shoulder pain (OR = 1.92, 95% CI = 1.24-2.98, P = 0.004); however, psychological distress was not (OR = 0.78, 95% CI = 0.42-1.42, P = 0.41). In conclusion, this is the first study indicating an association between sleep disturbance and new-onset subjective shoulder pain amongst the survivors of the GEJE.
2011年3月11日，东日本大地震及海啸重创了日本东北海岸。本研究旨在确定睡眠障碍和心理困扰等社会心理因素在东日本大地震灾后阶段是否会影响幸存者新发的主观肩部疼痛。在2012年11月至2013年2月（东日本大地震后2年）以及2014年11月至2015年1月（东日本大地震后4年）期间，幸存者（18岁及以上）回答了自填式问卷。共有1454名幸存者回复了问卷并被纳入本研究。新发主观肩部疼痛定义为在东日本大地震2年后无圈选反应的肩部疼痛，而在4年后出现。东日本大地震2年后，凯斯勒心理困扰量表-6得分≥10/24分，以及雅典失眠量表得分≥6/24分分别定义为存在心理困扰和睡眠障碍。采用多元逻辑回归分析来估计新发主观肩部疼痛与心理困扰或睡眠障碍之间关联的比值比（OR）和95%置信区间（CI）。在参与者中，7.2%（105/1454）报告有新发主观肩部疼痛。睡眠障碍与新发主观肩部疼痛显著相关（OR = 1.92，95%CI = 1.24 - 2.98，P = 0.004）；然而，心理困扰并非如此（OR = 0.78，95%CI = 0.42 - 1.42，P = 0.41）。总之，这是第一项表明东日本大地震幸存者中睡眠障碍与新发主观肩部疼痛之间存在关联的研究。
