"Workplaces, restaurants, homes and even bars are mostly smoke-free, but cars have been forgotten," says Emara Nabi-Burza, MBBS, MS, the study's lead author. "Smoking in cars is not safe for motorists and nonsmokers – especially children, who have no way to avoid tobacco smoke exposure in their parent's car. Now that we know the magnitude of the problem, pediatricians and the public can act to help these children." Nabi-Burza is an investigator with the Center for Child and Adolescent Health Policy at MGHfC.
The authors write that tobacco smoke can contribute to an increased risk of respiratory infections, cancer and even death in children. Homes have traditionally been considered the main indoor source of smoke exposure for children, but recent studies have found elevated levels of tobacco smoke contaminants in cars, says Nabi-Burza, noting that children may spend a considerable amount of time in their family's car.
In the study, researchers interviewed 795 smoking parents about their car-smoking policy and behavior, including whether they exposed their children to tobacco smoke in their cars. The participants were interviewed while exiting from their child's doctors' office in one of 10 pediatric practices in eight states. Seventy-three percent of the parents admitted that someone had smoked in their car in the past 3 months. Of the 562 parents who did not have a smoke-free car policy, 48 percent smoked in the car when their children were present. Most parents adopted a "strictly enforced" smoke-free policy in their homes, but only 24 percent of parents had a strictly enforced smoke-free policy for their cars.
Only about one-fifth of the parents reported being asked by a pediatric health care provider about their smoking status. Few of the parents who smoked (12 percent) were advised by the provider to avoid smoking in their cars. This is the first known study to examine the rates at which pediatricians address smoking in cars; and due to the low percentage of parents counseled on this issue, the authors conclude that pediatricians should address tobacco use with parents and encourage them to have strict smoke-free home and car policies to help reduce tobacco smoke exposure of children.
Because of their role in advocating for children's health, Nabi-Burza says pediatricians have the unique opportunity to counsel parents on creating a strict smoke-free car policy.
"An infant strapped in a car seat cannot advocate effectively for herself in the face of parental tobacco addiction. The pediatrician can help the parent set a no-smoking policy in the car," says Jonathan P. Winickoff, MD, MPH, the study's senior author. He is an associate professor of Pediatrics and Nabi-Burza is a research associate in Pediatrics at Harvard Medical School.

Massachusetts General Hospital, founded in 1811, is the original and largest teaching hospital of Harvard Medical School. The MGH conducts the largest hospital-based research program in the United States, with an annual research budget of more than $750 million and major research centers in AIDS, cardiovascular research, cancer, computational and integrative biology, cutaneous biology, human genetics, medical imaging, neurodegenerative disorders, regenerative medicine, reproductive biology, systems biology, transplantation biology and photomedicine. In July 2012, MGH moved into the number one spot on the 2012-13 U.S. News & World Report list of "America's Best Hospitals."

Mit dem Ultrakurzpulslaser lassen sich nicht nur feine Strukturen schneiden, in einem Verbundprojekt haben Wissenschaftler untersucht, wie man damit auch Mikrostrukturen in Dünnglas erzeugen kann. Anwendungen gibt es im Analytikbereich (lab-on-a-chip), aber auch in der Elektronikbranche und im Consumer-Bereich gibt es großes Interesse.
Am Anfang dieser neuen Methode stand ein überraschender Effekt: Wenn Glas mit dem Ultrakurzpulslaser in der richtigen Weise bestrahlt wird, wird es so...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Linsen, Objektive, Brillengläser oder auch Laser sind in der Regel mit einer Antireflexschicht versehen. Solche Schichten haben oft den Nachteil, dass sie nur innerhalb enger Wellenlängenbereiche optimal wirksam sind. Forscher des Max-Planck-Instituts für Intelligente Systeme in Stuttgart stellen nun eine alternative Technologie vor. Anstatt eine Beschichtung aufzubringen, bearbeiten sie die Oberfläche selbst. Im Vergleich zu herkömmlichen Verfahren können sie so den gewünschten Effekt über einen größeren Wellenlängenbereich erzielen, und das bei besonders großer Lichtdurchlässigkeit.
Der Nachtfalter macht es vor. Seine Augenoberflächen sind so beschaffen, dass sie einfallendes Licht praktisch nicht reflektieren. Keine Lichtreflexe – das...
