Introduction: Our study aims at identifying and quantifying the relationship between the cold and heat exposure and the risk of cardiovascular mortality through a systematic review and meta-analysis. Material and Methods: A systematic review and meta-analysis were conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. Peer-reviewed studies about the temperature and cardiovascular mortality were retrieved in the MEDLINE, Web of Science, and Scopus databases from January 2000 up to the end of 2015. The pooled effect sizes of short-term effect were calculated for the heat exposure and cold exposure separately. Also, we assessed the dose–response relationship of temperature-cardiovascular mortality by a change in units of latitudes, longitude, lag days and annual mean temperature by meta-regression. Result: After screening the titles, abstracts and full texts, a total of 26 articles were included in the meta-analysis. The risk of cardiovascular mortality increased by 5% (RR, 1.055; 95% CI [1.050–1.060]) for the cold exposure and 1.3% (RR, 1.013; 95% CI [1.011–1.015]) for the heat exposure. The short-term effects of cold and heat exposure on the risk of cardiovascular mortality in males were 3.8% (RR, 1.038; 95% CI [1.034–1.043]) and 1.1%( RR, 1.011; 95% CI [1.009–1.013]) respectively. Moreover, the effects of cold and heat exposure on risk of cardiovascular mortality in females were 4.1% (RR, 1.041; 95% CI [1.037–1.045]) and 1.4% (RR, 1.014; 95% CI [1.011–1.017]) respectively. In the elderly, it was at an 8.1% increase and a 6% increase in the heat and cold exposure, respectively. The greatest risk of cardiovascular mortality in cold temperature was in the 14 lag days (RR, 1.09; 95% CI [1.07–1.010]) and in hot temperatures in the seven lag days (RR, 1.14; 95% CI [1.09–1.17]). The significant dose–response relationship of latitude and longitude in cold exposure with cardiovascular mortality was found. The results showed that the risk of cardiovascular mortality increased with each degree increased significantly in latitude and longitude in cold exposure (0.2%, 95% CI [0.006–0.035]) and (0.07%, 95% CI [0.0003–0.014]) respectively. The risk of cardiovascular mortality increased with each degree increase in latitude in heat exposure (0.07%, 95% CI [0.0008–0.124]). Conclusion: Our findings indicate that the increase and decrease in ambient temperature had a relationship with the cardiovascular mortality. To prevent the temperature- related mortality, persons with cardiovascular disease and the elderly should be targeted. The review has been registered with PROSPERO (registration number CRD42016037673).

Introduction: Recent years have witnessed community disaster resilience becoming one of the most heavily supported and advocated approach to disaster risk management. However, its application has been influenced by the lack of assessment tools. This study reviews studies conducted using the resilience concept and examines the tools, models, and methods adopted. It examines the domains, indicators, and indices have been considered in the tools. It provides a critical analysis of the assessment tools available for evaluating community disaster resilience (CDR). Methods: We investigated international electronic databases including Scopus, MEDLINE through PubMed, ISI Web of Science, Cochrane Library, Cumulative Index to Nursing and Allied Health (CINAHL), and Google Scholar with no limitation on date, and type of articles. The search terms and strategy were as follow: (Disaster* OR Emergenc*) AND (Resilience OR Resilient OR Resiliency) that were applied for titles, abstracts and keywords. Extracted data were analyzed in terms of studied hazards, types of methodology, domains, and indicators of CDR assessment. Results: Of 675 publications initially identified, the final analysis was conducted on 17 full text articles. These studies presented ten models, tools, or indices for CDR assessment. These evinced a diverse set of models with regard to the domains, indicators and the kind of hazard described. Considerable inter dependency between and among domains and indicators also emerged from this analysis. Conclusion: The disparity between the articles using the resilience concept and those that offer some approach to measurement (675 vs. 17) indicates the conceptual and measurement complexity in CDR and the fact that the concept may be being used without regard to how CDR should be operationalized and assessed. Of those that have attempted to assess CDR, the level of conceptual diversity indicates limited agreement about how to operationalize the concept. As a way forward we summarize the models identified in the literature and suggest that, as a starting point for the systematic operationalization of CDR, that existing indicators of community disaster resilience be classified in five domains. These are social, economic, institutional, physical and natural domains. A need to use appropriate and effective methods to quantify and weigh them with regard to their relative contributions to resilience is identified, as is a need to consider how these levels interrelate to influence resilience. Although assessment of disaster resilience especially at the community level will inform disaster risk reduction strategies, attempts to systematically do so are in preliminary phases. Further empirical investigation is needed to develop a operational and measurable CDR model.

Older people are among the most vulnerable in major disasters. In their aftermath, it is crucial to institute efforts that will maintain a high level of elders' quality of life (QoL). This paper presents QoL assessments of elderly survivors five years after the Bam earthquake in Iran, and evaluates the determinants. A cross-sectional analysis of 210 randomly-selected survivors was carried out in 2008 using the WHOQOL-BREF questionnaire. A comparison of the results with data on the general population showed that experiencing the earthquake may adversely affect psychological dimensions of QoL even five years after, but paradoxically the earthquake resulted in better social relationships in affected communities than in the general population. Lower QoL associated with female gender, higher age, living alone, severe earthquake-related injury, poor quality of living conditions, increased dependency in the activities of daily living, living in an urban area, and being temporarily housed. Recovery experts and donors should carry out long-term monitoring of health status and QoL in disaster-affected communities, with a focus on psychological wellbeing. Intervention programmes that emphasise post-disaster quality of care and satisfactory housing may lead to better QoL of the victims and may shorten the recovery phase.

Objective: Proper shelter site selection is necessary for long-term welfare of earthquake affected people. This study aims to explore the criteria that need to be considered after earthquakes. Methods: Through a systematic review, 273 articles found that were published till April 2014. Among these, seven articles have been selected and analyzed for the criteria that they introduced for sheltering site selection after earthquakes. Results: Out of 27 proposed criteria, accessibility and proximity to homes of affected people were stressed in all the papers. Moreover, seven other criteria were the same in most of the papers including suitable size, suitable distance from hazardous areas, geological hazards and land slope, suitable distance from medical centers, water supply and Security. We categorized all the mentioned criteria in six main categories. Size and location, disaster risk reduction, relief and rescue facilities, feasibility of the site, environmental and social aspects are the main categories. Conclusion: Selection and applying proper criteria for shelter site selection after earthquakes is a multi-disciplinary task. The decision needs relevant models and/or tools. Geographic Information System (GIS) is a useful tool for this purpose. Key words: Disaster, earthquake, shelter, site selection, systematic review

Elders have long been recognised as among the most vulnerable people in disaster events. This paper reports a qualitative study of the self-perceived needs of older people in the aftermath of the Bam earthquake in Iran in 2003. A total of 56 people aged from 65 to 88 years were recruited to the study using purposive sampling, including 29 men and 27 women. Six focus group discussions and ten semi-structured individual interviews were conducted. Each focus group involved six to ten people from the cities of Bam and Baravat and their rural suburbs. Content analysis was used to analyse the transcribed data. The analysis identified four major themes among the informants' concerns: inappropriate service delivery, affronts to dignity, feeling insecure and emotional distress. A disaster-prone country like Iran needs to be appropriately prepared with culturally sensitive plans to meet the needs of those who suffer from their effects, not least older people. Emergency relief managers should note that for many older people in a disaster zone, customary forms of relief are neither required nor appropriate, and that their distinctive immediate and long-term needs should be assessed and met. Relief agencies need to be trained to be age-sensitive and should mainstream older people's rights in the planning and implementation of both the response and recovery phases of assistance.
