The Report on Children's Health and the Environment in America just released by the EPA shows trends for contaminants in air, water, food, and soil that may affect children; concentrations of contaminants in the bodies of children and women of child-bearing age; and childhood illnesses and health conditions.
“By monitoring trends, identifying successes, and shedding light on areas that need further evaluation, we can continue to improve the health of our children and all Americans,” said EPA Administrator Lisa P. Jackson.
Among the contaminants clearly linked to health conditions in children, key findings include:
The level of knowledge regarding the relationship between environmental exposures and health outcomes varies widely among the topics presented in this report, and the inclusion of an indicator in the report does not necessarily imply a known relationship between environmental exposure and children’s health effects. The report provides data for selected children’s health conditions that warrant further research because the causes, including possible contributing environmental factors, are complex and not well understood at this point.
In the case of asthma, researchers do not fully understand why children develop the condition. However, substantial evidence shows exposure to certain air pollutants, including particulate matter and ozone, can trigger symptoms in children who already have asthma. Although the report found the percentage of children reported to currently have asthma increased from 8.7 percent in 2001 to 9.4 percent in 2010 and that minority populations are particularly affected by asthma, the severity of children’s asthma and respiratory symptoms has declined. The rate of emergency room visits for asthma decreased from 114 visits per 10,000 children in 1996 to 103 visits per 10,000 children in 2008. Between 1996 and 2008, hospitalizations for asthma and for all other respiratory causes decreased from 90 hospitalizations per 10,000 children to 56 hospitalizations per 10,000 children.
The report also looks at trends in other health conditions, such as Attention-Deficit/Hyperactivity Disorder (ADHD) and preterm births, for which rates have increased. There is no conclusive information on the role of environmental contaminants in ADHD or preterm births, and additional research is ongoing.
The national indicators presented in the report are important for informing future research related to children’s health. Children may be more vulnerable to environmental exposures than adults because children’s bodies are still developing. Children eat more, drink more, and breathe more in proportion to their body size; and their behavior can expose them more to chemicals and organisms.
This report includes 37 indicators of children’s environmental health to address 23 important topics. The expanded content reflects the latest research on children’s health issues and the availability of data for more topics. Each indicator and its supporting text were peer reviewed by independent external experts and made available for review and comment by the public.
