Climate Change Exacerbates Skin Diseases Globally, Study Finds
A new international study involving 136 countries reveals climate change's significant impact on the prevalence and severity of skin diseases, disproportionately affecting low-income nations.
A comprehensive international study has found that climate change is significantly impacting the prevalence and severity of skin diseases worldwide. The research, encompassing 136 nations, indicates that over 40% of countries have reported climate-related changes in skin conditions, with low-income nations bearing a disproportionate burden.
The findings were presented at the European Academy of Dermatology and Venereology (EADV) Congress in Vienna. The SkinObservatory study, a collaboration between the International League of Dermatological Societies (ILDS) and L'Oréal Dermatological Beauty, gathered data from 136 countries across the World Bank's four income groups. Overall, 42.6% of participating countries reported changes in the prevalence or severity of skin diseases attributed to climate change.
Lower-income countries (55.6%) and lower-middle-income countries (52.5%) reported climate-related changes in skin diseases more frequently than upper-middle-income (43.8%) and high-income countries (28.3%). Significant geographical variations were also observed, with the Western Pacific region reporting the most changes (64.7%), followed by the Eastern Mediterranean and Southeast Asian regions (both 60.0%), compared to just 16.1% in the European region.
Among the 58 countries that reported on climate effects, 81% noted an increase in heat rashes and 75.9% in inflammatory skin conditions. Additionally, 62.1% reported changes in infectious diseases, and half (50.0%) reported alterations in vector-borne diseases. Researchers emphasize the need for enhanced surveillance, education, and locally tailored strategies, particularly in resource-limited settings.
