Study Finds Environmental, Lifestyle Risk Factors of Atopic Dermatitis in Preschool Children

by HomeDecorBeauty

Several environmental and lifestyle factors were associated with a significant risk of developing atopic dermatitis in preschool children in Shenzhen, China, including the presence of mold in children’s rooms, living in a villa/townhouse, and using laminate floors.

According to published in Frontiers in Public Health.

As one of the most prevalent inflammatory skin diseases in children, AD risk has been shown to be influenced by genetic, environmental, and social factors. In addition, residential and family environmental variables may also play a role in AD risk, although few studies have investigated this effect in children.

“Dietary habits, such as vegetable and fruit intake, and lifestyle factors (eg, parental smoking) may also increase the odds of eczema. But the results of the current study are partly conflicting, probably because there are many dietary and lifestyle factors confounding factors,” they added.

To investigate the association of dietary habits, residential/home environment, and lifestyle with AD risk in children, researchers conducted a cross-sectional analysis of data from nationwide China-Child-Home-Healthy Chinese Shenzhen preschoolers (CCHH). ) 2015-2016 study.

“The rapid urbanization and industrialization in China has changed people’s consumption patterns, lifestyles and living environment. At the same time, the prevalence of childhood eczema is also increasing rapidly,” the study authors noted.

Of the 4614 questionnaires collected from 30 kindergartens in Shenzhen, China, 2781 were included in the analysis. Several factors of dietary habits, residential/home environment, and lifestyle were assessed, and logistic regression models were used to analyze these associations:

  • Eating habits examined are meat, seafood, fruits, vegetables, beans/grains, rice/pasta, eggs, milk and fast food
  • Living environment including location (residential area and proximity to highways), size, age, and type of dwelling
  • Home environment, which is the indoor environment formed by personal habits, including mold, wet stains, water stains, condensation on windows, house decoration condition (floor material and whether to repaint children’s rooms)
  • Lifestyle was defined as the daily life and living habits of children and their families, including the frequency of cleaning and ventilation and drying of bedding, time spent watching TV/playing on the computer, keeping pets at home and smoking in children’s rooms
  • Adjusted for the effects of ambient air pollution in regression models

In the entire study cohort, the prevalence of AD in preschool children was 24.6%, compared with other cities in China such as Wuhan (23%) and Shanghai (21.1%), as well as developed countries in Spain (21.9%) and Sweden (23.0%), indicating that AD is a widespread public health problem.

For several variables, including the use of laminate flooring (adjusted OR [aOR]1.777; aOR, 1.911), lived in a villa/townhouse (aOR, 3.102; aOR, 2.156), had mold or wet stains in children’s rooms (aOR, 1.807; aOR, 2.279), rarely cleaned children’s rooms (aOR, aOR, 2.156) , 1.513; aOR, 1.540).

In addition, watching TV/playing computer games for more than 1 hour per day was significantly associated with physician-diagnosed AD (aOR, 1.172) and AD-like symptoms (aOR, 1.174). Eating rice/pasta 1 to 3 times a week was also shown to increase the risk of developing AD-like symptoms (aOR, 1.343), and the researchers said further investigation was needed.

Since ambient air pollution was included in the adjusted covariates, they added that this may also affect the risk of AD in children.

“Parents and kindergarten staff should try to avoid overloading their children with electronic tasks and create a low-risk living environment for children as they grow,” the researchers concluded.
