Association Between Climate Change Awareness and Depression & Anxiety: Findings from a U.S. Sample

Background: Exploring the connection between climate change awareness and overall well-being is crucial, particularly in how it impacts both the environment and mental health. The mental health consequences of climate change and its awareness have not been thoroughly examined, especially in the U.S. In this study, the relationship between awareness of climate change and depression or anxiety among U.S. adults was explored. Similarly, the role of climate change awareness has not been explored in relation to mental health concerns. Methods: Based on the HINTS-6 dataset, a nationally representative, cross-sectional survey conducted by the National Cancer Institute, a variety of statistical methods, including logistic regression models, to examine these relationships were used. This study had a sample size of 6154 participants. A statistically significant level of <0.05 was used. Result: The findings showed that individuals who are aware of climate change have a higher adjusted odds ratio of 1.392 (1.160–1.671) for experiencing depression or anxiety compared to those who are unaware. Additionally, non-heterosexual individuals displayed a significantly higher adjusted odds ratio of 2.691 (CI: 2.125–3.407) for depression or anxiety, underscoring the strong connection between mental health and climate change awareness. Conclusion: This study highlights a notable link between heightened awareness of climate change with depression and anxiety among the U.S. population.
