Background: Although natural disasters can threaten health and well-being, some people show greater resilience to their effects than others. Identifying the characteristics related to resilience has important implications for reducing the health risks in the aftermath of a disaster.
Objective: Using the Conservation of Resources Theory as a framework, we study the role of resources in moderating the adverse effects of natural disasters on people's health and coping behaviors.
Method: We match 20,658 unique individuals aged 50 or older from the 2012-2016 waves of the Health and Retirement Study to the county-level annual natural hazard data provided by the Federal Emergency Management Agency. Using individual-fixed effect models, we first model whether the experience of natural disasters can predict people's health and coping behaviors. We then explore heterogeneity in such effects by interacting individual- and county-level resilience resources with the number of natural disasters.
Results: The results show that with increased exposure to natural disasters, older adults are more likely to experience difficulties performing instrumental daily activities. They also tend to have fewer overnight hospital stays, higher out-of-pocket medical expenses, and increased alcohol dependency. However, older adults with certain socio-economic characteristics ‒ white, higher education, higher income, and homeownership ‒ are better able than others to mitigate any adverse health effects of natural disasters. One significant community-level resource is a robust healthcare capacity in a county with a high ratio of healthcare practitioners, where older adults are more likely to seek hospital care and have lower alcohol dependency.
Conclusions: Health resilience can be improved by strengthening community-level healthcare capacity, with a particular focus on residents with lower socio-economic resources. Failing to address healthcare provision inequalities may exacerbate health disparities.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

Climate change is rapidly transforming ecosystems and reshaping the landscapes of animal health, with profound consequences for public health, food security, and biodiversity. Rising temperatures, shifting weather patterns, and increased frequency of natural disasters are driving the emergence and spread of infectious diseases, particularly zoonotic and vector-borne diseases. These environmental shifts endanger the health and welfare of animals and the delicate balance between human populations, livestock, and wildlife.

Drought is a significant environmental stressor that induces changes in the physiological, morphological, biochemical, and molecular traits of plants, ultimately resulting in reduced plant growth and crop productivity. Seaweed extracts are thought to be effective in mitigating the effects of drought stress on plants. In this study, we investigated the impact of crude extract (CE), and polysaccharides (PS) derived from the brown macroalgae Fucus spiralis (Heterokontophyta, Phaeophyceae) applied at 5% (v/v) and 0.

Climate change is an emerging global health crisis, disproportionately affecting low- and middle-income countries (LMICs) where health outcomes are increasingly compromised by environmental stressors such as pollution, natural disasters, and human migration. With a focus on promoting health equity, Global Surgery advocates for expanding access to surgical care and enhancing health outcomes, particularly in resource-limited and disaster-affected areas like LMICs. The healthcare industry-and more specifically, surgical care-significantly contributes to the global carbon footprint, primarily through resource-intensive settings, i.

Background: Competing definitions of posttraumatic stress disorder (PTSD) have been proposed by ICD-11 and DSM-5; it is unclear which diagnostic model works best for children and adolescents. Although other studies have predicted the impact of these models by approximating the criteria using older measures, this study advances the research by comparing measures designed to assess ICD-11 and DSM-5 criteria in hurricane-exposed youth. This study evaluates ICD-11 and DSM-5 (both the standard and preschool-age) diagnostic models by identifying diagnostic rates, evaluating diagnostic concordance, investigating the predictive value of constructs associated with PTSD (demographics, disaster threat and exposure, functional impairment), and examining model fit.
