Secondhand smoke raises odds of fertility problems in womenDecember 05, 2008If you need another reason to quit smoking, consider that it may diminish your chances of being a parent or grandparent. Scientists at the University of Rochester Medical Center have found that women exposed to second hand smoke, either as adults or children, were significantly more likely to face fertility problems and suffer miscarriages. An epidemiologic analysis of more than 4,800 non-smoking women showed those who were exposed to second hand smoke six or more hours per day as children and adults faced a 68 percent greater chance of having difficulty getting pregnant and suffering one or more miscarriages. The study is published online in Tobacco Control and is one of the first publications to demonstrate the lasting effects of second hand smoke exposure on women during childbearing years. "These statistics are breathtaking and certainly points to yet another danger of second hand smoke exposure," said Luke J. Peppone, Ph.D., research assistant professor at Rochester's James P. Wilmot Cancer Center. In the study, four out of five women reported exposure to second hand smoke during their lifetime. Half of the women grew up in a home with smoking parents and nearly two-thirds of them were exposed to some second hand smoking at the time of the survey. More than 40 percent of these women had difficulty getting pregnant (infertility lasting more than a year) or suffered miscarriages, some repeatedly. "We all know that cigarettes and second hand smoke are dangerous. Breathing the smoke has lasting effects, especially for women when they're ready for children," said Peppone, who analyzed information in the Patient Epidemiology Data System, a well-studied cohort that has yielded information on a variety of cancers. Peppone analyzed surveys collected from 4,804 women who visited Roswell Park Cancer Institute for health screenings or cancer care from 1982-1998. The 16-page survey focused on lifestyle, habits, family and personal health history, and occupational and environmental exposures. Each participant in this study reported that they had never smoked, and had been pregnant at least once or tried to become pregnant. Participants reported whether one or both of their parents smoked and if they lived with or worked with smokers as adults. They also estimated the amount of time they were exposed to second hand smoke. Peppone acknowledges that the data is based upon self-reporting and that is not perfect. However, he said "Women, especially mothers, have extremely accurate recall. Mothers can easily recall details like how long they breastfed, what vitamins they took during prenatal care, and childhood activities." Many of the women in the study grew up in the 1940s and 1950s, long before the surgeon general issued the first warning about the dangers of cigarette smoking in 1964. Since then, millions of dollars were spent to study the dangers of cigarette smoking. Tobacco use contributes to more than nearly 90 percent of all deadly lung cancers and 30 percent of all cancer deaths in the U.S., and a host of other health problems Since the mid-1960s, smoking bans and government-funded, anti-smoking campaigns have encouraged smokers to quit and discouraged others from starting using a number of passive and aggressive techniques. Smoking rates have declined, however people continue to use tobacco and suffer the health risks. University of Rochester Medical Center |

New study finds smoking predicts increased stroke risk for your spouse Although Second Hand Smoke (SHS) is widely accepted as a risk factor for coronary heart disease, there have been few studies investigating the association of SHS and stroke risk. In a new study, published in the September 2008 issue of the American Journal of Preventive Medicine, researchers report on evidence of increased risk of stroke for spouses of smokers. Global momentum for smoke-free indoor environments at tipping point In a Perspective in the April 12, 2007 issue of The New England Journal of Medicine (NEJM), researchers from the Harvard School of Public Health (HSPH) and the Association of European Cancer Leagues describe the growing momentum for indoor smoking bans in countries across the globe.

Should all hospitals be smoke free? The recent decision by the Royal Victoria Hospital in Belfast to build seven smoking rooms for patients and staff at a cost of £500,000 provoked condemnation from many sources. In this week's BMJ researchers argue that these resources might have been better used to implement a smoking ban and expand smoking cessation activities. The value of hospitals making a clear statement on public smoking can be seen from a recent study showing that total workplace bans would have an effect equivalent to an almost doubling of the price of cigarettes in the United Kingdom. Other considerations include protection of other patients and staff from exposure to second hand smoke, and a reduction in the Passive smoking increases the risk of heart disease A new study published in BMC Public Health shows that breathing in second-hand smoke significantly increases the risk of developing heart problems in non-smokers. These findings have serious consequences for public health giving weight to calls for smoking to be banned in public places. In 1995 cardiovascular diseases accounted for nearly 15 million deaths, approximately 30% of deaths worldwide. Smokers are becoming increasingly aware of the links between smoking and heart disease as warnings such as "smoking causes heart disease" are emblazoned across cigarette packaging across the world.

Led by Philip Morris, manufacturers gave money to hospitality associations, even creating their own body, to stifle opposition to smoke-free premises, says the research. They preyed on unsubstantiated fears that profits would be lost by switching to a no smoking policy, promoting the idea that no-smoking sections and expensive ventilation systems would address concerns about the health of patrons exposed to second hand tobacco smoke. The documents show that the industry began its campaign in the 1970s, intensifying it i Hair samples may be more accurate measure of exposure to second hand smoke Strands of hair accurately measure second hand tobacco smoke exposure, finds research in the Journal of Epidemiology and Community Health. And they may be more effective than currently used methods, suggest the authors. More Second Hand Smoke Current Events and Second Hand Smoke News Articles |
