Abstract
Background: Although environmental factors have been studied for their impact on mental health, the link between ambient temperature and mental disorders remains insufficiently explored.
Aim: This study aimed to explore the relationship between ambient temperature and the frequency of emergency psychiatric consultations at the sole university hospital in Paraguay from 2021 to 2023.
Methods: This investigation adopted a quantitative, observational, cross-sectional design, using a case-crossover approach. Data collection entailed reviewing patient records and meteorological data, focusing on the daily mean temperatures and other meteorological variables. Statistical analysis was conducted using RStudio and SPSS, applying a distributed lag non-linear model (DLNM) for a seven-day lag period. Multinomial logistic regression was used to estimate odds ratios (ORs) for the likelihood of specific diagnoses resulting in emergency consultations in relation to temperature exposure.
Results: The analysis covered 2,186 first-time emergency psychiatric consultations, with anxiety disorders being the most frequent diagnosis (24.3%), followed by depressive disorders (23.4%) and personality disorders (15.8%). Women accounted for 70.6% of all patients. The findings indicated that higher temperatures were associated with a greater frequency of consultations for certain disorders, including bipolar (OR up to 27.12 at Lag 1) and eating disorders (OR up to 100 at Lag 1). Conversely, a negative association was observed for schizophrenia, dissociative disorders, and trauma- and stressor-related disorders as temperature increased. Additionally, a linear relationship was found between lower relative humidity and increased number of consultations.
Conclusions: The findings underscore the impact of ambient temperature on psychiatric emergency consultations, revealing that the frequency of consultations for different conditions varies with temperature. These insights could inform public health strategies to mitigate the effects of climatic variation on mental health. These findings suggest the need for targeted mental health interventions to address vulnerabilities during periods of climatic stress, particularly in resource-limited settings.
期刊介绍：
The International Journal of Social Psychiatry, established in 1954, is a leading publication dedicated to the field of social psychiatry. It serves as a platform for the exchange of research findings and discussions on the influence of social, environmental, and cultural factors on mental health and well-being. The journal is particularly relevant to psychiatrists and multidisciplinary professionals globally who are interested in understanding the broader context of psychiatric disorders and their impact on individuals and communities.
Social psychiatry, as a discipline, focuses on the origins and outcomes of mental health issues within a social framework, recognizing the interplay between societal structures and individual mental health. The journal draws connections with related fields such as social anthropology, cultural psychiatry, and sociology, and is influenced by the latest developments in these areas.
The journal also places a special emphasis on fast-track publication for brief communications, ensuring that timely and significant research can be disseminated quickly. Additionally, it strives to reflect its international readership by publishing state-of-the-art reviews from various regions around the world, showcasing the diverse practices and perspectives within the psychiatric disciplines. This approach not only contributes to the scientific understanding of social psychiatry but also supports the global exchange of knowledge and best practices in mental health care.
