Caregivers often contain asthmatic children in the smoke

NEW YORK (Reuters Health) - Secondhand Effects of cigarette smoke is a trigger for asthma in children and a new study shows that smoking is the main educator and child care are important sources of smoke exposure in children with asthma.

The study of children with asthma who were exposed to passive smoking "was so much smoke exposure, and if their mothers smoked," Dr Harold J. Farber told Reuters Health.

Children with a double blow to environmental tobacco smoke - of both their suppliers and the day of Trustees - have high levels of nicotine metabolites in urine, said Farber, Texas Children's Hospital in Houston.

Farber and his colleagues tested the urine samples of 519, 3 - to 12-year-old children with asthma nicotine metabolites showed the effects of passive smoking. They also asked parents of children tell their children's exposure to secondhand smoke in their homes and in other areas where children spend a considerable time.

More than three-quarters of children have been studied poorly controlled asthma, the researchers note in the medical journal Chest. Sixty-three percent of children were not allowed to smoke caregivers.

Tests showed that low levels of nicotine metabolite in children not reported the impact of passive smoking - about half the population of the study.

Caregiver reports for the remaining young people showed that those exposed to passive tobacco smoke, either at home or in the afternoon were similar levels of nicotine metabolites, and these levels were significantly higher than unexposed children.

Children exposed to passive smoke at home and the day was the highest overall level of nicotine metabolites.

"Parents who smoke often underestimate the impact on their children," Farber told Reuters Health. But the majority of primary caregivers are receptive to the idea of limiting the impact, research shows. This can be achieved through home smoking sections or retention of children from tobacco smoke a public place.

Farber suggests that health workers caring for children with asthma offer parents to help stop smoking.
