After the 2011 Fukushima nuclear power plant accident, the prevalence of metabolic syndrome sharply increased in municipalities near the nuclear power plant, where a massive evacuation of community residents occurred (the evacuation area). However, after the initial increase, the rate of increase in metabolic syndrome in the evacuation area was slower than that in the surrounding area (non-evacuation area). In this study, we compared the incidence of and recovery from metabolic syndrome as well as its prevalence between evacuation and non-evacuation areas during the 10 years after the accident to explore whether the slower increase in metabolic syndrome after the initial increase in the evacuation area stemmed from suppressed incidence or from fast recovery. We analyzed specific health check-up data of community residents aged 40-74 in Fukushima Prefecture from fiscal year (FY) 2012 to FY 2021 (N = 710,201). To explore the prevalence of metabolic syndrome, we examined the associations of time, residential area, and their interaction with metabolic syndrome using mixed-model repeated measures. We used data from those without metabolic syndrome in FY 2012 to investigate the incidence. We similarly examined the associations of time, residential area, and their interaction with metabolic syndrome using FY 2013 to FY 2021 data. To explore recovery, we used the data of those with metabolic syndrome in FY 2012 and repeated the same procedure. The rate of increase in the prevalence and incidence of metabolic syndrome was slower in the evacuation area than in the non-evacuation area. On the other hand, as for the recovery, the time trend of metabolic syndrome did not differ between the two areas. The slower increase in metabolic syndrome in the evacuation area was partly explained by the slower incidence in the evacuation area but not by recovery.
2011 年福岛核电厂事故后，在发生大规模社区居民撤离（撤离区）的核电厂附近市町村，代谢综合征的流行率急剧上升。然而，在最初增加之后，撤离区代谢综合征的增长率比周围地区（非撤离区）慢。在这项研究中，我们比较了事故发生后 10 年撤离区和非撤离区代谢综合征的发病和恢复情况以及其流行率，以探讨撤离区代谢综合征在最初增加后增长率较慢是否是由于发病率受到抑制还是由于恢复较快。我们分析了福岛县 2012 财政年度至 2021 财政年度（N=710201）40-74 岁社区居民的特定健康检查数据。为了探讨代谢综合征的流行率，我们使用混合模型重复测量法，研究了时间、居住地区及其相互作用与代谢综合征之间的关系。我们使用 2012 财政年度无代谢综合征的数据来调查发病率。我们同样使用 2013 财政年度至 2021 财政年度的数据，研究了时间、居住地区及其相互作用与代谢综合征之间的关系。为了探讨恢复情况，我们使用 2012 财政年度有代谢综合征的数据，并重复了相同的程序。与非撤离区相比，撤离区代谢综合征的流行率和发病率的增长率较慢。另一方面，就恢复而言，两个地区的代谢综合征时间趋势没有差异。撤离区代谢综合征增长率较慢的部分原因是撤离区发病率较慢，但不是恢复。
