National Institute of Environmental Research, Republic of Korea

Network of WHO Collaborating Centres for Children’s Environmental Health

The WHO Collaborating Centre for Vulnerable Populations and Environmental Health at the National Institute of Environmental Research (NIER) in the Republic of Korea, conducts scientific research to improve the health of children, pregnant women, and the elderly, who are the most vulnerable to environmental health issues. Specifically, NIER Centre research examines how exposure to metals, phthalates, and phenols affects the health of these vulnerable populations.

In a global network of researchers committed to protecting children’s environmental health, the NIER Centre is:

  • Conducting collaborative research projects aimed at finding risk factors for environment-related disorders in vulnerable populations, including infants, children, and pregnant women.
  • Building research capacity in developing countries, particularly in the Asia-Pacific region.
  • Hosting and participating in international programs and collaborative research on vulnerable populations and environmental health.

Chemicals/Exposures studied Metals, phenols, phthalate metabolites
Health or social effects studied Health behaviors, socioeconomic status, BMI classification, anemia, growth and development, neurodevelopment, diabetes, dyslipidemia, prevalence of asthma, and atopic dermatitis
Population(s) studied The Mother and Children’s Environmental Health (MOCEH) birth cohort was launched in 2006 and 1,751 mothers were enrolled from Seoul (a metropolitan area), Cheonan (control), and Ulsan (an industrial city).
From 2005 to 2010, the Children’s Health and Environmental Research (CHEER) enrolled 7,059 children from 33 primary schools in 10 cities. One-third of CHEER participants (n = 2,770) were followed 2 and 4 years after enrollment.

From 2012 to 2014, the Korean Environmental Health Survey in Children and Adolescents (KorEHS-C) was conducted in nationally representative 2,300 children and adolescents aged 3 to 18 from 62 child care centers and kindergartens and 120 schools.

The new birth cohort study, Korean Children’s Environmental Health Study (Ko-CHENS) has been established from 2015 and the follow-up survey will be conducted in every growth stages for the following 22 years. 100,000 mothers will be enrolled from 13 Environmental Health Centers.
