Saúde Mental e Crise Climática: A Necessidade de uma Abordagem Proativa em Resiliência Comunitária e Preparo para Desastres
As mudanças climáticas configuram uma ameaça imediata e crescente à saúde global, comsendo descritas como o maior desafio sanitário do século XXI. Seus impactos abrangem desde ondas de calor, desastres ambientais e insegurança hídrica e alimentar até a intensificação de doenças infecciosas e não transmissíveis. Estima-se que mais de 3,6 bilhões de pessoas vivam em condições de alta vulnerabilidade climática, especialmente em países de baixa e média renda, perpetuando desigualdades históricas.

Preliminary Report on Symptoms of Anxiety, Depression, and PTSD Following Severe Flooding in Brazil: A Longitudinal Perspective
Objectives: This preliminary longitudinal web-based study examines the progression of anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms among individuals affected by severe flooding in Rio Grande do Sul, Brazil. The aim is to provide data that can inform early interventions and future research on mental health following disasters. Methods: Sixty-four participants were assessed during the flood (T1) and 1 month later (T2). Evaluations included sociodemographic data, trauma exposure, and symptoms of depression, anxiety, acute stress disorder (ASD), and PTSD. Results: Depression and anxiety symptoms remained relatively stable between T1 and T2, while posttraumatic symptoms increased significantly, particularly re-experiencing and avoidance. This progression suggests a shift from initial hyperarousal to more entrenched symptoms of reliving trauma and avoidance, indicating that the long-term effects of trauma may be more closely tied to PTSD. Additionally, trauma exposure and specific ASD symptoms predicted PTSD severity at T2. Conclusions: The results suggest a time-dependent progression of PTSD symptoms, with initial hyperarousal giving way to re-experiencing and avoidance, which are central to PTSD. Early psychoeducational interventions targeting re-experiencing symptoms and avoidance may help reduce PTSD severity. Further research in larger, more diverse samples is needed to assess generalizability.
