ISGlobal: Long-term exposure to UV radiation is associated with childhood eczema prevalence


News from ISGlobal


ISGlobal participated in an international study that examined the relationship between exposure to UV radiation and the prevalence of eczema in children. This ecological study concluded that UV exposure at the country level was associated with eczema prevalence also at the country level. Among other results, this research reported that countries with higher mean monthly UV radiation had higher country averages of eczema prevalences among 13-14 year-old.

This study, published in the Journal of Investigative Dermatology, was conducted using data from the International Study of Asthma and Allergies in Childhood (ISAAC), and includes information on children 13-14 years of age from 214 schools in 87 countries and children 6-7 years of age from 132 schools in 57 countries.

ISGlobal researcher Elaine Fuertes, the first author of the study, commented: “Thanks to the large dataset available in the ISAAC study, we were able to conduct the first study examining the relationship between UV exposure and eczema in children and adolescents in a global context”, while adding that the results should be interpreted with caution “until they can be reproduced using prospective data with individual exposures”. Nevertheless, this new study supports the hypothesis that UV exposure explains some of the variation in the prevalence of childhood eczema around the world.
