摘要
背景:据报道，2011年东日本大地震和海啸后脑血管疾病(cvd)的发病率暂时上升;然而，目前还没有研究对其长期影响进行调查。我们评估了灾难对心血管疾病发病率的长期影响。方法:2008年至2017年心血管疾病发病率数据来自日本岩手县基于人群的卒中登记和库存调查。岩手县部分沿海地区被轻度洪水淹没，另一部分则被严重洪水淹没。计算每个地区的年龄调整后心血管疾病发病率(根据日本标准人口)。根据灾前年份(2008-2010年)和灾后年份(2012-2017年)，计算各地区按分层年龄组调整的发病相对风险(RR)。结果:各地区经年龄调整后的发病率逐渐下降，只有沿海地区男性在灾害发生当年出现了短暂的上升。灾害年份调整后的RR在所有地区均不显著，灾后年份的RR在所有内陆男性为0.91 (95% CI 0.87-0.96)，所有内陆女性为0.93(0.89-0.97)，所有沿海男性为0.85(0.78-0.93)，所有沿海女性为0.87(0.81-0.94)，轻度洪水海岸男性为0.88(0.80-0.98)，轻度洪水海岸女性为0.82(0.75-0.89)，严重洪水海岸男性为0.79(0.68-0.91)，严重洪水海岸女性为0.98(0.86-1.11)。结论:东日本大地震和海啸发生时，沿海洪水淹没区心血管病发病率没有增加;此外，根据随后几年洪水破坏的严重程度，男性的死亡率有所下降;这可归因于对海啸受害者的支助活动和人口的迁移。
Occurrence of Cerebrovascular Diseases Decreased after the Great East Japan Earthquake and Tsunami of 2011.
Background: A temporary increase in the occurrence of cerebrovascular diseases (CVDs) after the Great East Japan Earthquake and Tsunami of 2011 was reported; however, no studies have been conducted to investigate long-term effects. We assessed the long-term impact of the disaster on the incidence of CVDs.
Methods: Incidence data for CVDs from 2008 to 2017 were acquired from the population-based Stroke Registry with an inventory survey of Iwate Prefecture, Japan. Part of the coastal area in Iwate Prefecture was mildly flooded and the other part was severely flooded. Age-adjusted incidence rates of CVDs (according to the Japanese standard population) were calculated for each area. The relative risk (RR) of incidence based on the years before the disaster (2008-2010), adjusted by stratified age groups, was calculated for the year of the disaster (2011), and the years after the disaster (2012-2017) in each area.
Results: The age-adjusted incidence rates gradually decreased in all areas, with the exception of a temporary increase among men who lived on the coast the year the disaster occurred. The adjusted RR in the disaster year were not significant in any area and those of the postdisaster years were 0.91 (95% CI 0.87-0.96) for all inland men, 0.93 (0.89-0.97) for all inland women, 0.85 (0.78-0.93) for all coastal men, 0.87 (0.81-0.94) for all coastal women, 0.88 (0.80-0.98) for men at mildly flooded coast, 0.82 (0.75-0.89) for women at mildly flooded coast, 0.79 (0.68-0.91) for men at severely flooded coast, and 0.98 (0.86-1.11) for women at severely flooded coast.
Conclusions: The occurrence of CVDs in the flooded coastal areas did not increase in the year of the Great East Japan Earthquake and Tsunami; furthermore, it decreased for men according to the severity of flood damage in the subsequent years; this can be attributed to supportive activities for the tsunami victims and the migration of the population.
期刊介绍：
This open access and online-only journal publishes original articles covering the entire spectrum of stroke and cerebrovascular research, drawing from a variety of specialties such as neurology, internal medicine, surgery, radiology, epidemiology, cardiology, hematology, psychology and rehabilitation. Offering an international forum, it meets the growing need for sophisticated, up-to-date scientific information on clinical data, diagnostic testing, and therapeutic issues. The journal publishes original contributions, reviews of selected topics as well as clinical investigative studies. All aspects related to clinical advances are considered, while purely experimental work appears only if directly relevant to clinical issues. Cerebrovascular Diseases Extra provides additional contents based on reviewed and accepted submissions to the main journal Cerebrovascular Diseases.
