Can pre-disaster community resilience enhance post-disaster recovery among older adults? A natural experiment in Iwanuma City after the 2011 Great East Japan Earthquake and Tsunami
As large-scale disasters occur more frequently worldwide, understanding how pre-disaster community resilience influences post-disaster recovery has become imperative for disaster risk-reduction policy and practice. This study investigated whether pre-disaster community resilience helped explain post-disaster subjective recovery following the 2011 Great East Japan Earthquake and Tsunami. We conducted a baseline survey of older residents in Iwanuma…

Pre-disaster income inequality and post-disaster mental health
Resilience Factors Affecting Long-Term Trajectories of Depressive Symptoms in the Aftermath of the Great East Japan Earthquake and Tsunami Among Older Adults
Objectives We examined long-term trajectories of depressive symptoms among older adults following exposure to the 2011 Great East Japan Earthquake and Tsunami. We further characterized the pre- and post-disaster social relationship factors that predicted membership in each trajectory group. Methods Data from 4 time points (including pre-disaster data) were used to analyze the depression trajectories of 2,033 survivors through a group-based trajec…
Association between housing damage, present bias and delayed-onset post-traumatic stress symptoms among older adults 9 years after a natural disaster
BACKGROUND: Previous studies suggest that experience of natural disasters may heighten present bias. Research also suggests that impaired self-control (in particular, heightened present bias) could be linked to delayed-onset post-traumatic stress symptoms (PTSS) among survivors of natural disasters. We examined a hypothesis that the association between disaster experiences and delayed-onset PTSS is mediated through present bias among older surviv…
Community-level social capital and cognitive decline after a natural disaster
Reciprocity of social support is associated with psychological distress and suicidal ideation in older Japanese people
Predictors of decline in Iadl functioning among older survivors following the Great East Japan earthquake
Predictors of depressive symptoms following the Great East Japan earthquake
Combined effects of eating alone and living alone on unhealthy dietary behaviors, obesity and underweight in older Japanese adults
We examined whether eating alone is associated with dietary behaviors and body weight status, and assessed the modifying effects of cohabitation status in older Japanese people. Data from the 2010 Japan Gerontological Evaluation Study, with a self-reported questionnaire for 38,690 men and 43,674 women aged ≥65 years, were used. Eating status was classified as eating with others, sometimes eating alone, or exclusively eating alone. We calculated a…
Effect of a community intervention programme promoting social interactions on functional disability prevention for older adults
BACKGROUND: The efficacy of promoting social interactions to improve the health of older adults is not fully established due to residual confounding and selection bias. METHODS: The government of Taketoyo town, Aichi Prefecture, Japan, developed a resident-centred community intervention programme called 'community salons', providing opportunities for social interactions among local older residents. To evaluate the impact of the programme, we cond…
Relative deprivation in income and mortality by leading causes among older Japanese men and women
BACKGROUND: Relative deprivation of income is hypothesised to generate frustration and stress through upward social comparison with one's peers. If psychosocial stress is the mechanism, relative deprivation should be more strongly associated with specific health outcomes, such as cardiovascular disease (compared with other health outcomes, eg, non-tobacco-related cancer). METHODS: We evaluated the association between relative income deprivation a…
