Prevalence of Eczema on Rise in Developing Countries
Researchers at Centre of Evidence-Based Dermatology at The University of Nottingham has found that eczema, a form of dermatitis or inflammation of the upper layers of the skin, is still on the rise in developing countries.

The research, conducted by a team of allergy experts across the world, tracking the number of cases of childhood eczema across the globe has revealed big changes in the prevalence of the condition over the last five to ten years and suggests that environmental factors might be responsible for the condition.

The study has shown a levelling off in the number of cases of eczema in children aged between 13 to 14 years and a decrease in some countries like the UK and New Zealand where childhood eczema was once highly prevalent.

Their study suggests that environmental factors are key factor for eczema expression because it is highly unlikely that genetic factors would change in such a short time.

Hywel Williams, Professor of Dermato-Epidemiology in the Centre of Evidence-Based Dermatology at The University of Nottingham and lead author of the study, said that eczema need to be tackled at a public health level in many countries.

The researchers analysed over 300,000 children aged 13 to 14 years from 105 centres in 55 countries and nearly 190,000 children aged six to seven years from 64 centres in 35 countries.

The largest decreases in kids aged between 13 to 14 years were seen in developed countries in northwest Europe, such as the United Kingdom, Ireland, Sweden, Germany and also New Zealand.
