Researchers at the New York University's Langone Medical Center said a November survey by Britain's Department of Health found more than a third of children in Britain said they would go without any Christmas presents; 78 percent would commit to doing their homework every night and 76 percent would go to bed when told if their parent quit smoking.
Seven-out-of 10 many children said they worry about their parent dying.
"Try to quit for your children and grandchildren, and make your home smoke-free for the holidays," a statement from NYU's Langone Medical Center said. "New Yorkers can call for a free personalized quit plan, call 1-866-NY-QUITS or visitwww.nysmokefree.com."
Children exposed to secondhand smoke are more likely to suffer ear infections, colds, severe asthma attacks, and lung problems, the researchers said.
No survey details were provided.
