Healthcare professionals' acquaintance with climate change in India: impact on health, adaptation and mitigation strategies

Background Climate change is one of the most pressing global public health threats of the 21st century, affecting human health through increased respiratory and vector-borne diseases, food and water insecurity, extreme weather events and mental health challenges. Vulnerable populations, including children, the elderly, and those in low-resource settings, are disproportionately affected. India is particularly vulnerable due to existing health and social inequities, underscoring the need for a climate-literate health workforce. This study aimed to assess awareness among healthcare professionals regarding the health impacts of climate change and to examine their understanding of mitigation and adaptation strategies.

Methods An exploratory cross-sectional survey was conducted using convenience sampling among doctors, nurses, and paramedical professionals working across India. Data were collected online via a structured questionnaire covering climate dynamics, health impacts and vulnerability. Ethical approval and informed consent were obtained. A total of 1009 participants responded between October 2024 to April 2025.

Results Most participants were nurses (89.4%), females (68.3%) and aged 26- 30 years. Nearly all respondents (98.2%) reported experiencing climate change in their localities. The mean knowledge score was moderate (10.0 ± 2.65 out of 24), with doctors scoring highest. Significant gaps were identified in understanding mitigation and adaptation concepts.

Conclusions Despite great concern about climate change, healthcare professionals demonstrated limited conceptual clarity and engagement, highlighting an attitude-action gap and the need for strengthened climate-health education and training.
