Proposal for a modification of the UVI risk scale.

Area of Science:

• Atmospheric Science
• Public Health
• Photobiology

Background:

• The Ultraviolet Index (UVI) is a globally accepted standard for UV radiation information.
• Current UVI descriptors and health messages are primarily based on European skin types and UV conditions.
• This limits the direct applicability of UVI to equatorial populations, especially at high altitudes.

Purpose of the Study:

• To address the limitations of the current UVI scale for equatorial regions.
• To propose modifications for the UVI to enhance its relevance and applicability in Latin America.
• To support the Arequipa Accord's goal of coordinating UV and health research in the region.

Main Methods:

• Analysis of existing UVI scale limitations.
• Review of UV radiation characteristics in equatorial, high-altitude regions.
• Development of suggestions for UVI scale adaptation.

Main Results:

• Identified disparities between current UVI guidelines and the UV exposure experienced in regions like the Altiplano.
• Proposed specific adjustments to UVI descriptors and associated health messages.
• Highlighted the need for region-specific UV information.

Conclusions:

• The international UVI scale requires adaptation to accurately reflect UV exposure and health risks in diverse geographical and demographic contexts.
• Tailoring the UVI is crucial for effective public health communication and UV protection strategies in Latin America.
• Further research and collaboration are needed to refine and implement region-specific UVI applications.
