Prolonged periods of living in prefabricated houses (PHs) may increase the risk of musculoskeletal (MSK) symptoms; however, the association is not clear. This study aimed to investigate the association between continued residence in PHs and MSK pain in a population affected by a natural disaster, the Great East Japan Earthquake (GEJE) survivors.
DESIGN, SETTING AND PARTICIPANTS: A panel study was conducted including 1059 and 792 survivors at 2 and 4 years, respectively, after the GEJE, using a self-reported questionnaire. Those with no response on living status and those who did not live in a PH were excluded. Participants were classified into two groups by living status: continued residence in a PH (lived in a PH during both periods) or moving out of a PH (lived in a PH in the first period and did not live in a PH in the second).
MSK pain included lower back, shoulder, knee, hand or foot, and neck pain. Changes in the occurrence of MSK pain during the two periods were assessed and defined as 'new-onset' and 'continuing' MSK pain. Multiple logistic regression analysis was used to examine the influence of continued residence in a PH on new-onset and continuing MSK pain.
Continued residence in a PH was significantly associated with new-onset MSK pain, even after adjustment for covariates (adjusted OR 2.18, 95% CI 1.25 to 3.79, p=0.006). Participants who continued living in a PH had higher rates of continuing MSK pain than those who moved out; however, the difference was not significant (adjusted OR 1.69, 95% CI 0.94 to 3.05, p=0.079).
Continued residence in a PH was associated with new-onset MSK pain among survivors. Public support should be provided to such people to ensure a more comfortable life.
长期居住在预制房屋（PHs）中可能会增加肌肉骨骼（MSK）症状的风险；然而，这种关联尚不清楚。本研究旨在调查在受自然灾害影响的人群——东日本大地震（GEJE）幸存者中，持续居住在PHs与MSK疼痛之间的关联。
设计、背景与参与者：采用自我报告问卷对GEJE发生后2年和4年时分别纳入的1059名和792名幸存者进行了一项队列研究。未对居住状况做出回应者以及不住在PH中的人员被排除。参与者按居住状况分为两组：持续居住在PH中（两个时期均居住在PH中）或搬出PH（第一个时期居住在PH中，第二个时期不住在PH中）。
MSK疼痛包括下背部、肩部、膝盖、手部或足部以及颈部疼痛。评估两个时期内MSK疼痛发生情况的变化，并将其定义为“新发”和“持续存在”的MSK疼痛。采用多因素logistic回归分析来检验持续居住在PH中对新发和持续存在的MSK疼痛的影响。
即使在对协变量进行调整后，持续居住在PH中仍与新发MSK疼痛显著相关（调整后的比值比为2.18，95%置信区间为1.25至3.79，p = 0.006）。持续居住在PH中的参与者持续存在MSK疼痛的比例高于搬离者；然而，差异不显著（调整后的比值比为1.69，95%置信区间为0.94至3.05，p = 0.079）。
在幸存者中，持续居住在PH中与新发MSK疼痛相关。应向这类人群提供公共支持，以确保他们的生活更舒适。
