FRIDAY, Aug. 29 (HealthDay News) -- Babies born prematurely to women who smoked during their pregnancy may be at higher risk of sudden infant death syndrome (SIDS) than premature infants born to nonsmoking moms, new research suggests.

The Canadian study is the first to compare the breathing reflexes of "preemies" born to smokers versus nonsmokers. The researchers found that these tiny babies were more likely to have impaired recovery from pauses in breathing if their mother had smoked during her pregnancy.

I can always tell when a parent of a child I'm treating is a smoker. The examination room is just filled with smoke - not too different from the experience you'd have if you walked into a bar or restaurant that still allows smoking. My style is to ignore it until the very end of the visit - sneaky, I know! I just forge ahead trying to not inhale too much air. I have to admit, there have been times I've had to find excuses to leave the room to get a few smoke-free breathes of air!!

FRIDAY, Aug. 8 (HealthDay News) -- A gene variant that may influence a person's initial response to smoking and lifetime smoking habits has been identified by a team of researchers.

The finding about the variant in the CHRNA5 nicotine receptor gene may help explain how someone goes from trying their first cigarette to becoming a long-term smoker.

Previous studies have inked variations in the same genetic region to a smoker's level of nicotine dependence, to the number of cigarettes smoker per day, and to an increased risk of lung cancer.

TUESDAY, July 29 (HealthDay News) -- Despite high levels of smoking, Japanese men are far less likely to have dangerous plaque build-up in their blood vessels than white or Japanese-American men, a difference that researchers believe stems from a lifelong, near-daily consumption of fish.

As we celebrate the anniversary of women's right to vote on August 26th, Women's Equality Day, we need to draw attention to the effect of tobacco-related diseases on women.

Lung cancer has surpassed breast cancer as a leading killer of women. Smoking and exposure to secondhand smoke increases the risk of heart disease, which kills one of three women in the United States. Babies born to women who smoke and babies who are exposed to secondhand smoke after birth are at greater risk for sudden infant death syndrome (SIDS), asthma, and other chronic lung diseases.

THURSDAY, July 17 (HealthDay News) -- Community-based health programs aimed at diet, exercise, smoking prevention and other known risk factors for chronic diseases could cut health-care costs in the United States by $16 billion a year, a new report says.

"We worked with economists at the Urban Institute who looked at health-care costs associated with these chronic diseases," said Jeffrey Levi, executive director of the Washington-based Trust for America's Health, which issued the report. "They estimated a 5 percent reduction in these chronic diseases to derive these savings."
