NEW YORK (Reuters Health)-
According to a study by Czech families, children who grew up in coal-heated homes may grow poorly due to long-term exposure to indoor air pollution.
By the age of 3, about half of the children living in homes that use coal for heating
On average, it\'s a few inches shorter than those who rely on other forms of heating fuel.
The researchers said the impact on the growth of children exposed to coal and cigarette smoke at home was greater, and they reported their findings in the pediatric and adolescent medical files.
Whether these children will catch up with their peers on the growth chart, or whether the impact is permanent, scientists say, is unclear.
However, Irva Hertz said studies of children exposed to cigarette smoke showed that children with shorter stature would last until puberty and could enter adulthood
Pijoto of the University of California at Davis is the author of the new study.
According to the World Health Organization, about half of the world\'s population burns coal, feces, wood or crop waste for heating or cooking.
Indoor air pollution is as high as 1.
The organization estimates that 6 million people die each year.
Coal smoke is known to cause lung damage, but the new study \"is important because it shows that there are some systemic effects on the whole body,\" Hertz-Picciotto said.
Her research team surveyed 1,133 children in two coal-widely used areas in the Czech Republic.
The researchers matched the child\'s medical history at birth and at 36 months with the information collected by the family survey completed by the parents.
More than 10% of households rely on coal for heating or cooking (
About the fifth of these fuels also uses other fuels, such as wood).
At the age of 3, the child who grew up in coal
About one burning household.
The researchers found that the average number of households heated by other fuels was 3 cm shorter.
The boys are slightly different.
Children exposed to coal and cigarette smoke at home are about 0.
At the age of 3, it was 8 inch shorter than those exposed to two pollutants.
Even after the researchers explained some of the known effects on the physical development of young children, such as breastfeeding, parental education, the effects of exposure to indoor coal smoke
Reflects the wealth of a family.
And whether the child is premature. Hertz-
Picciotto said that she and her colleagues may not be able to fully explain the impact of economic conditions or family nutrition on the development of children.
Even so, she does not believe that socio-economic status will distort the findings.
While the soot mist contains many potentially harmful chemicals, such as mercury, arsenic, and multi-ring aromatic hydrocarbons, experts say they are not sure how these substances prevent children from growing.
One explanation is that harmful chemicals interfere with the cells in the growth plate --
The area at the end of the long bone, such as the leg femur, the tissue is still expanding-
Len Horowitz, a lung specialist at Lenox Hill Hospital in New York, said he was familiar with the latest research.
These substances may also disrupt hormones that regulate normal growth.
