Abstract
BACKGROUND Disaster-related relocation is associated with depression and post-traumatic stress disorder, especially in older adults. Disaster-related relocation often deprives survivors of opportunities for social group participation, potentially deteriorating their mental health. On the contrary, the relocation could also be an opportunity for optimizing social relationships, ending/reducing unwanted participation. This study examined the potential mediation effects of changing participation for the link of disaster-related relocation to mental health. METHODS We analyzed a pre-post disaster dataset of functionally independent older adults from the Japan Gerontological Evaluation Study. Following the 2013 survey, a follow-up survey was conducted seven months after the 2016 Kumamoto earthquake (n = 828). RESULTS The causal mediation analyses indicated that compared to no relocation, the relative risk for experiencing major depressive episodes among those relocating to temporary housing was 3.79 [95% confidence interval: 1.70-6.64] (natural direct effect). By contrast, the relative risk for those renewing (either ceased or started) group participation was 0.60 [95% CI: 0.34-0.94] (natural indirect effect). CONCLUSIONS Optimization of social ties according to a renewal of group participation status might have protected older adults in temporary housing against depression.

Abstract
BACKGROUND Participating in groups with diverse members is associated with improved health among older adults. The study examined the relationship between diversity of group members and needed support or long-term care. METHODS We conducted a longitudinal study for the Japan Gerontological Evaluation Study with 61,281 participants aged ≥ 65 years who were surveyed in 2013 and followed-up for six years. We assessed three dimensions of the diversity of the participating members (sex, age, and region of residence). We then graded the diversity level into four categories: level 0 (not in any group), level 1 (in a group without diversity or in a group with diversity in one of the three factors), level 2 (in a group with diversity in two of the three factors), or level 3 (in a group with diversity across all factors). We adjusted for 12 covariates using Cox hazard survival analysis models with hazard ratios (HRs) and 95% confidence intervals (CIs) estimated for the association between group members' diversity levels and needed support or long-term care. The same study was conducted when stratified by employment status at baseline. RESULTS Participants in social participation groups with more diverse group members had a lower incidence of needed support or long-term care as compared to their counterparts. Compared to those with no participation group, HR decreased by 14% to 24% with increasing levels of diversity. The HR for the level of care needed for participants in the social participation group with high residential diversity was 0.89 (95% CI: 0.84-0.94). For participants who were currently unemployed, HR reductions ranged from 16%-28% with increasing levels of diversity compared to the non-participating group. No association was found for employed participants. CONCLUSIONS The reason the HRs of Japanese elderly people certified as needing support or care are lower when the diversity of participating groups is higher could be owing to the presence of a variety of people and the diversification of social networks, which facilitates the building of bridging social relational capital. Public health policies that encourage participation in diverse organizations will be important in the future.

Abstract
Background and aim Social capital involves a set of norms available in social systems which improves the interaction between people and reduces the costs of interactions and communications. The purpose of this research was to study the social capital of the students of Kurdistan University of Medical Sciences and its related factors, 2017. Material and methods The method of this study was the descriptive survey. The statistical sample of this study included all students of Kurdistan University of Medical Sciences among whom 378 students were selected randomly as the study sample. Delaviz questionnaire of social capital was employed for data collection and data analysis was performed using SPSS software, through descriptive statistics (mean, standard deviation) and Inferential statistics (U-Mann Whitney, Kruskal-Wallis). Results The mean of social capital was 70.56 ± 10/88. The minimum and maximum mean was measured for “participation in local community” and “group participation”, respectively. In this study, there were significant associations between social capital and gender, field of study as well as marital status (p < 0/01). Conclusions Social capital is known as the most important factor for people dealing with stressful situations, and can facilitate toleration of problems for them. It can also support the health and life satisfaction of students.

Abstract
Social activities in the community help older adults maintain functional ability. Community organizing, based on the assessment of health risks, community assets, and fostering intersectoral organizational partnerships, could increase participation opportunities. Supporting municipality staff members in building their capacity to take those actions might benefit them. Nevertheless, the effectiveness of such support remains unclear. This real-world-setting study evaluated the effectiveness of providing support for municipality health sectors in relation to older residents’ social activities. Based on the Japan Gerontological Evaluation Study (JAGES), a nationwide study of community-dwelling older adults, from 2013 to 2016 researchers collaborated with health sector staff members in 13 participating municipalities (intervention group) in utilizing the JAGES-based community assessment data and building organizational partnerships. The remaining 12 municipalities (control) obtained the data only. We analyzed the longitudinal data of 47,106 older residents, performing a difference-in-differences (DID) analysis, weighted by the inverse of propensity to be selected for the intervention group, allowing for a multilevel (municipality/individual) data structure. In the intervention group, the estimated group participation prevalence in men increased by 10.4 percentage points from 47.5% to 57.9%, while in the control group, participation increased by 7.9 percentage points from 47.2% to 55.0% (DID estimated = 0.025, P = 0.011). No statistically significant difference between the two groups was observed among women (P = 0.131). Support for community organizing may improve group participation among older male residents. The community-attributable impact could be large, given that the intervention has the potential to work for all older residents in the municipality. Older men participated more where researchers and health sector collaborated well. The effects were specifically strong for participation in leisure activity groups. Community organizing might encourage older men to engage in social activities.
