即使灾害发生已过去一年多，尚不清楚受自然灾害影响的地区的残疾发生率是否高于其他地区。这项生态研究的目的是调查东日本大地震（GEJE）和海啸发生后的三年内，受灾地区老年人口残疾患病率的增长率是否较高。该分析使用了覆盖 1570 个城市的公共长期护理保险 (LTCI) 数据。 “灾区”被认为是受地震和海啸影响最严重的三个县：岩手县、宫城县和福岛县。结果衡量指标是获得 LTCI 残疾认证的老年人（≥ 65 岁）人数。以2011年1月至2014年1月残疾发生率变化率作为主要结果变量，通过“沿海灾区”、“内陆灾区”和“非灾区”之间的协方差分析进行比较。沿海灾区（14.7%）和内陆灾区（10.0%）残疾患病率平均增幅高于非灾区（6.2%）（P < 0.001）。震后3年来，灾区残疾发生率较GEJE之前的增幅持续较高。 (C) 2015 年作者。由 Elsevier Ltd 出版。这是一篇遵循 CC BY-NC-ND 许可证 (http://creativecommons.org/licenses/by-nc-nd/4.0/) 的开放获取文章。
It has been unclear whether the prevalence of disability is higher in an area affected by natural disaster than in other areas even if more than one year has passed since the disaster. The aim of this ecological study was to examine whether the rate of increase in disability prevalence among the older population was higher in disaster-stricken areas during the 3 years after the Great East Japan Earthquake (GEJE) and tsunami. This analysis used public Long-term Care Insurance (LTCI) data covering 1570 municipalities. "Disaster areas" were considered to be the three prefectures most affected by the earthquake and tsunami: Iwate, Miyagi, and Fukushima. The outcome measure was the number of aged people (>= 65 years) with LTCI disability certification. Rates of change in disability prevalence from January 2011 to January 2014 were used as the primary outcome variable, and compared by analysis of covariance between "coastal disaster areas", "inland disaster areas" and "non-disaster areas". The mean rate of increase in disability prevalence in coastal (14.7%) and inland (10.0%) disaster areas was higher than in non-disaster areas (6.2%) (P < 0.001). During the 3 years after the earthquake, the increase of disability prevalence from before the GEJE continued to be higher in the disaster-stricken areas. (C) 2015 The Authors.
