After the Fukushima nuclear accident in 2011, there was confusion among the public caused by uncoordinated information about radiation provided by diverse channels. We explored the association between information sources regarding reconstruction progress after the disaster and mental fatigue in Fukushima. We used data from the annual public opinion survey by the Fukushima Prefectural Government on its policies from 2013 to 2015, which contained survey responses from 1,300 community residents randomly selected from the 28 municipalities in the Fukushima Prefecture. The survey contained a question assessing mental fatigue: "How often do you usually feel mentally tired or depressed?" In total, 2,130 participants (758 participants in 2013, 699 participants in 2014, and 673 participants in 2015) were analyzed. The respondents were classified as two categories, "high mental fatigue" and "low mental fatigue," based on their responses to this question. Overall, the proportion of participants with high mental fatigue was 13.2%. There was no association between the year of survey or occupation and high mental fatigue. Cluster analysis was performed to classify information sources. Then, we conducted a crosssectional analysis of the associations between clusters of information sources and high mental fatigue. We found that unreliable information sources, such as "Internet" and "a combination of TV, radio, and word of mouth," were significantly associated with high mental fatigue, compared with reliable information sources, such as "municipal public relations in addition to major media (newspaper, TV, and radio)." These findings provide important insights into how information sources affect mental fatigue following a disaster. [ABSTRACT FROM AUTHOR]

Many studies have consistently reported the bidirectional relationship between problem drinking and psychological distress following a disaster, but the risk factors of problem drinking following a disaster remain unclear. In this study, we therefore aimed to explore the risk factors associated with the incidence of problem drinking among evacuees after the Great East Japan Earthquake of March 11, 2011. We used the data for evacuees of the Fukushima Daiichi nuclear power plant accident, obtained from the Mental Health and Lifestyle Survey. A total of 12,490 individuals from 13 municipalities, which included the evacuation order areas after the accident, completed surveys between 2012 and 2013. The CAGE (Cutting down, Annoyed by criticism, Guilty feeling, and Eye-opener) questionnaire was used to screen the participants for alcohol dependence, and a score. 2 indicated problem drinking. Logistic regression models were applied to investigate the possible predictors of problem drinking. The results showed that insufficient sleep and heavy drinking (. 4 drinks per day) were significant risk factors for the incidence of problem drinking in both men and women. Additional risk factors included family financial issues due to the disaster and trauma symptoms among men and a diagnosed history of mental illness among women. Other remaining variables were not significantly associated with problem drinking. The present study is the first to identify the risk factors for problem drinking following a compound disaster. Our findings could be used to develop a primary intervention program to improve evacuees' health and lives following a disaster. [ABSTRACT FROM AUTHOR]

After Fukushima disaster in 2011, the health status of the region's residents deteriorated. We analyzed the health status, care needs, and access to health services among evacuees and non-evacuees using healthcare expenditure (for self-employed and unemployed individuals aged < 75 years) and long-term care expenditure (mainly for individuals aged = 65 years). Fukushima Prefecture was divided into four areas according to their evacuation status: non-EOAs (municipalities that did not include evacuation order areas (EOAs)); EOAs/non-EOAs (municipalities that included both EOAs and non-EOAs); short-term EOAs (municipalities where the EOA designation was lifted in most areas by fiscal year (FY) 2011); and long-term EOAs (municipalities where most EOA designations remained in place until the end of FY 2015). Increases in expenditure on healthcare and long-term care per capita in short-term and long-term EOAs were greater in FY 2015 than the average values in FYs 2008-2010. The increases in expenditure were higher in shortterm and long-term EOAs than those in non-EOAs and EOAs/non-EOAs. The increases in dental health expenditure were attributed to enhanced accessibility to dental health facilities. Furthermore, the evacuations contributed to increases in healthcare and long-term care expenditure, independent of aging and improved accessibly to health facilities. Possible explanations for these increases include the poor health status of the evacuees following the evacuations, reduced availability of informal care provided by family members and neighbors, and reduced patient copayments. The findings highlight the necessity of health promotion among evacuees. [ABSTRACT FROM AUTHOR]

Psychological distress has become a serious health risk after the Fukushima nuclear accident. Although, following the lifting of evacuation orders, the affected people have started returning home, their current status of psychological distress has not been reported yet. Here, we report the levels of psychological distress in both returnees and evacuees by using a K6 indicator. In January 2018, questionnaires were randomly distributed among 2,000 people, aged 20 to 79 years old, who were registered on the Basic Resident Register in the evacuation order areas of nine municipalities where residents have now started returning home. The total number of participants was 625. The returnees showed a significantly better psychological distress status than the evacuees. Multivariate-adjusted odds ratios (95% confidence intervals) among the returnees (reference = evacuees), estimated from a logistic analysis by using age, sex, and annual income as covariates, were 0.525 (0.325-0.846) for K6 = 10 and 0.444 (0.216-0.911) for K6 = 13. The prevalence of K6 = 10 in the returnees when adjusted by the age and sex distribution of the whole of Japan was 16.2%, higher than the value (10.3%) at 20 to 79 years old in the whole of Japan. Psychological distress among the evacuees is an urgent problem to be resolved, and social support is still necessary for the returnees. Long term follow-up of returnees, investigations of causality between return and psychological distress and its governing factors in each of the evacuee and returnee groups are required for the implementation of effective countermeasures.

Since the 2011 Fukushima accident, rebuilding society to protect against anxiety and improve feelings of well-being has grown in importance. A questionnaire was carried out among residents of Marumori Town, Igu County, Miyagi Prefecture, to evaluate the effects of radiation-related countermeasures implemented by the town to reduce residents' anxiety and improve their subjective well-being (response rate: 31%; valid responses: n = 174). Further, to propose effective countermeasures regarding town planning for the improvement in subjective well-being, we analyzed associations between residents' sense of attachment to the town and subjective well-being, and then identified primary factors behind their sense of attachment. Marumori Town, located about 50 km to the northwest of the Daiichi Nuclear Power Station, is a good site for evaluating the effects of countermeasures taken by the town itself to fight anxiety, because there have been limited surveys and professional medical support, and mitigation efforts were primarily initiated by the town. The results suggested that decontamination evaluations were associated with a reduction in anxiety after the accident, which contributed to an increase in residents' subjective well-being. On the other hand, the evaluation of items related to human interactions in the community and the natural environment was found as a primary factor of sense of attachment toward the town, which contributed to an increase of residents' subjective well-being. This is the first study to quantitatively measure the effects of radiationrelated countermeasures on reducing anxiety and to propose an effective policy approach for improving subjective well-being.

After the Fukushima Daiichi nuclear accident in 2011 and thyroid examinations of children in Fukushima, the Radiation Medical Science Center began “Explanatory meetings on thyroid examination” as a method of communication with residents such as the subjects themselves and their guardians. Through questionnaires, we examined the relationship between anxiety (regarding the effects of radiation on the thyroid) before the meetings and individual attributes including attitudes on radiation, and then verified the effects of the meetings using measures of anxiety, comprehension, and satisfaction, as the outcomes. Of the meetings in 2014-2015, 799 people attended 30 sessions in Kenchu, Kenpoku, Iwaki, Soso, and outside of Fukushima Prefecture, and 594 people responded the questionnaires before and after the meetings on the same day. Level of anxiety before the meetings varied depending on individual attributes (including attitudes regarding collection information on radiation, advisors on radiation, and levels of subjective understanding), highlighting the importance of presenting information about radiation in a manner that is easy to understand, as well as providing opportunities for the exchange of opinions. Participation in meetings reduced anxiety. This was largely attributed to explanations about general characteristics of cancer and objective facts, including doses; status of the Chernobyl accident; and comparison in results of thyroid examinations with other prefectures in Japan. An opportunity for a question-and-answer session also contributed to increased overall satisfaction. The lower number of meeting participants was associated with anxiety reduction and higher subjective comprehension. The present findings obtained will be useful to facilitate evidence-based risk communication. [ABSTRACT FROM AUTHOR]
