Following the accident at the Fukushima Nuclear Power Plant in March 2011, both experts and the national government provided insufficient information on radiation, leading to widespread distrust in the community. This study aimed at clarifying the association between anxiety about radiation and health literacy among residents in evacuation and non-evacuation areas in Fukushima. A questionnaire survey was sent to randomly sampled residents between August and October 2016, and data from 777 responses (38.9% valid response) were analyzed. The questionnaire assessed current radiation anxiety and discrimination and prejudice based on radiation exposure through seven items and communicative and critical health literacy through five items. Multiple regression analysis of the association between radiation anxiety and health literacy showed that the level of health literacy was significantly negatively associated with radiation anxiety in the evacuation areas (marginally in the non-evacuation areas) and marginally negatively associated with discrimination and prejudice in the evacuation areas but not in the non-evacuation areas. Therefore, improving health literacy could alleviate radiation anxiety.
Support for older evacuees should focus on maintaining their physical activity level as well as on HRQOL to avoid deterioration of health in these survivors. (Disaster Med Public Health Preparedness. 2017;11:701-710).
Objective: The aim of this study is to assess the risk factors for incident functional disability among long-term evacuees of Iitate village after Great East Japan Earthquake and nuclear disaster (GEJE). We also investigated the effectiveness of exercise classes as an intervention measure in this situation. Methods: 1159 subjects (75.2 ± 5.8 years, 57.5% female) were included at baseline, and followed-up for four years. Cox proportional hazard regression analysis was used to estimate the hazard ratio (HR) of incident functional disability according to the presence of risk factors evaluated by the municipality’s self-assessment Basic Checklist (BCL). Evacuees from Iitate who participated in the exercise classes and those who did not were matched using the propensity scores, which were then used to obtain the HR of incident functional disability. Results: New functional disability occurred in 280 (24.2%) participants during the follow-up. Participants who scored negative for the “Physical function” domain in the BCL had a HR of 2.04 (95% CI: 1.54–2.69) for incident functional disability when compared to those who scored positive for this domain. Similarly, the HR for “Cognitive function” was 1.37 (CI: 1.06–1.77), and 1.60 (CI: 1.24–2.08) for “Depression”. Using a Cox proportional hazard regression model, both the group with low-participation in the exercise program and the group with high-participation in the exercise program had a significantly lower rate of incident functional disability compared to those who did not participate at all (HR = 0.27, CI: 0.16–0.46; HR = 0.30, CI: 0.12–0.74, respectively). Conclusions: Pre-disaster BCL domains were useful to identify individuals at risk of functional disability after a major socio-technical disaster. Therefore, this instrument can be used to identify at-risk older adults who would benefit from early exercise programs to prevent incident functional disability.
The 2011 nuclear disaster in Fukushima was not only a health disaster, but also an information disaster. Although media can promote health communication following disasters, studies have revealed associations between media information and negative psychological reactions. To clarify the relationship between media utilization and current health anxiety due to radiation exposure, a cross-sectional questionnaire survey was conducted in Fukushima. We selected 2000 subjects from evacuation (i.e., 500) and non-evacuation (i.e., 1500) areas by two-stage stratified random sampling. As the independent variable, participants were asked about current health anxiety due to radiation exposure at the time of answering the questionnaire. For utilization of media about radiation exposure, local media, national media, Internet media, public broadcasts, and public relations information from local government were set as the dependent variables. Questionnaire data were analyzed by evacuation type (i.e., forced/voluntary). In a multivariate logistic regression analysis, the use of public relations information was significantly associated with lower anxiety for the forced evacuees (odds ratio: 0.72; 95% confidence interval: 0.56–0.93). Our findings highlight the importance of public relations information from local government in terms of it being associated with lower current health anxiety, and this could potentially aid in preparing for future disasters.
We aimed to (1) describe the subjective well-being (SWB) of older residents in Fukushima Prefecture seven years and seven months after the Great East Japan Earthquake (GEJE) and examine the effect of relocation to the restoration public housing (RPH) on SWB, social capital, and health indicators; and (2) investigate the association between social capital and SWB. Questionnaires were administered to collect data of both RPH and non-RPH residents (≥65 years). Respondents’ SWB was collected via the Japanese version of the World Health Organization Five Well-Being Index. Additionally, residents’ social capital (trust, reciprocity, and participation), physical activity level, social network, functional health, history of chronic disease, and demographic data were collected. We analyzed 101 responses (valid response rate: approximately 34%) from RPH and 158 (53%) from non-RPH residents. SWB was lower in RPH compared to non-RPH residents but not statistically significant. Older RPH residents may demonstrate lower social capital and health indicators after the GEJE. Mistrust was found to be positively associated with low SWB in RPH residents. Future studies should examine the effectiveness of support for enhancing the trust of older RPH residents regarding, for example, the involvement of scientists—including medical professionals—in risk communications in promoting SWB.
