Pregnant women: Secondhand smoke can harm your unborn baby

Even if you don't smoke when you're pregnant, just being around smokers, can increase the risk of harming your future baby, according to a new study in the medical journal Pediatrics.

Researchers found exposure to secondhand smoke increased a non-smoking pregnant woman's chances of having a stillborn by 23 percent, and increased the risk of delivering a baby with birth defects by 13 percent.

"These results highlight the importance of smoking prevention and cessation focusing on the father in addition to the mother, during the preconception period and during the pregnancy," explains Dr. Jonathan Winickoff, Associate Professor of Pediatrics at Harvard Medical School, who is not affiliated with the study.

The team of experts reviewed virtually all available studies worldwide that focused on this health issue.

The scientists aren't exactly sure what levels of secondhand smoke are dangerous, but they do think the more exposure the higher the risks.

"We anticipate that the effect becomes significant when the woman is exposed to more than 10 cigarettes a day, which isn't a lot when you consider that some women are exposed to partners and other people's smoking habits on a daily basis. However, we need more evidence to be able to say with certainty what the true levels are," explains study author Jo Leonardi-Bee, PhD and Associate Professor in Medical Statistics at the University of Nottingham in England.

This research also suggests that secondhand smoke can be almost as dangerous to a baby as having a mother who smokes, at least when referring to stillbirths and birth defects.

Pregnant smokers have a 20 to 34% increase risk of having a baby who is stillborn compared to women who don't smoke, according to Dr. Winickoff. The risks weren't much less – 23% – for the non-smokers exposed to secondhand smoke.

The picture for birth defects is similar. The range for smoking women and birth defects is between 10 – 34%, and for pregnant women who are around smokers, 13%. Babies exposed to passive smoke were more likely to be born with major deformities of the feet, testes, or not have a brain.

"We know there are at least 400 toxic chemicals in tobacco smoke. These can get into the pregnant mother and affect her baby," says Dr. Winickoff.

Cigarettes contain heavy metals, DNA damaging agents, and class one carcinogens – the most harmful ones known.

"Protect yourself from passive smoke before and during pregnancy, not only to reduce risks of disease to yourself, but also to reduce the many harms that passive smoke can have on your future baby," says Leonardi-Bee.

      How can people be so ignorant? I've worked as an organic chemist in drug discovery for 10 years and I've never encountered another professional chemist that smoked. That's because chemists are educated and we know the following facts:

      1) Cigarette smoke contains carbon monoxide – Hemoglobin binds to carbon monoxide in your lungs instead of oxygen and then carries it through your bloodstream....killing your cells.....and yes cells are part of you...duh
      2) Cigarette smoke contains benzo[a]pyrene, one of most deadly carcinogens known to man. A P-450 metabolite of this compound inhibits the tumor suppression enzyme P-53. So therefore, P-53 cannot "repair" your DNA if too busy reacting with this metabolite.
      3) Nicotine is still used as an insecticide in some countries and Indians (Native Americans) used to rub tobacco leaves on themselves to keep bugs away.

      If America took science more seriously and actually taught kids what they are actually inhaling into their lungs, there would be far less smokers.

      To you smokers, it's not about personal freedom and keeping the government out of your lives, it's about wasting resources and being selfish. When your "personal choice" gives you cancer or heart disease, you cannot afford the treatment and then we all get to pay for your "PERSONAL CHOICE"

      You know, every time I walk out of a building and a wave of tobacco smoke consumes my breath of fresh air, I get so angry. I give the person an evil glare, because even though they have the freedom to smoke, I have the freedom NOT TO SMOKE OR BREATH IN OTHER PEOPLES SMOKE! Ban smoking in public, and make then stay home to smoke... make it child abuse to allow your kids to breath smoke, when it would be equal abusive to leave them in a burning building filled with smoke knowing you could get them out easily. My ability to sing and be athletic was ruined due to 13 years of second hand exposure from my step father in the house, in the car, hanging out on the porch, etc. I got burned several times. He always stunk, and the only good part was when he used the tobacco on a bee sting because I was allergic and it actually helped.

      My god. Lets do a study on how much car pollution with hurt an unborn fetus. I live in San Francisco currently and I find it funny that a lot of people here that glare at others for smoking during the day will light up and not care one bit while they are drinking. I would like to have public smoking areas through the city and im not saying one every few miles. There needs to be one on only one side of the street every other block or so. This would help on public smoking and cig butts on the ground. Non-Smokers need to get a grip. If you inhale a small amount of air and cig smoke its basically as harmful as the air your breathing right now. This is for people passing by. Not staying in the same room. Every time I step outside and walk to work I have to breath your cars smoke. Ban cars in public areas then lets talk about cigs. HAH!

    I hope tobacco is outlawed completely!.Then people will still be having breathing problems and then where will the blame go??? Look how long people have been fighting the tobacco lobby and we still are legal with tobacco. If it ever gets outlawed, maybe the next cause will be the pollution from the oil used in the millions of cars, diesel trucks, etc. Good luck shutting them down!...Alternative energy, don't count on it! The oil lobby will fight this for many more years to come...we're all gonna die sometime from something!

      It is good that we have environmental laws limiting polution by cars, and we should continue to attempt to make the environment a cleaner place to breath in – from reducing exposure to cigarette smoke, to all sorts of pollution. Without any regulations, the world can be a very disgusting place. I traveled to Arequipa and Cuzco Peru lately and my lungs felt terrible after walking around all day – I desperately needed to go inside. I hear cities in China and elsewhere are even worse. Thank goodness the U.S. works to make sure we aren't exposed to so much pollution, and I would be happy with additional work to try to decrease it further. The transportation thing is tough because we need it to get to work and to live our lives – so it makes sense to eliminate it where we can from completely unnecessary sources that we do not need.

    The Bear – you must be a FOX loyalist and Tobacco company propagandist. I am the child of smoking parents. Mom smoked during and after. I have physical birth defects. She had 4 kids – that survived; 3 miscarriages. I think the science supports the evidence in this case. My smoking uncle died of lung cancer. Yes, smoking is bad and so is second hand smoke. If people can avoid it, good for them.
    I think that the desire for a "crutch" of some sort, maybe even addiction itself, is a common human trait. And we are very orally inclined for satisfaction. Cigarettes provide that fix; nicotine keeps people hooked. Pure exploitation.

      And a good friend of mine, who neither smokes nor is around anyone that does, had five miscarriages before finally conceiving. Anecdotal evidence exists on both sides. And as long as people miscarry whether smoking or not, we can never definitively prove one thing or the other.

      Yes, anecdotal evidence exists on all sides, then again, if folks would take their study to sources such as Ovid and Pubmed and learn to critically appraise all bench/clinical trials and learn a little about statistics along the way, instead of relying on CNN or "Phillip Morris" for their data, they would have no questions, first and second hand smoking are dangerous activities, especially to the young. I agree, enough with the anecdotal evidence when there are boatloads of data out their to clearly demonstrate the links with smoking and pulmonary disease, cardiovascular disease, the impact of second-hand smoke, the impact on children.

      And, actually, given statistical methods of correcting for confounding variables, yes, a link between an independent variable (smoking in this case) and an outcome (miscarriage) can be clearly delineated with a very high confidence interval. It's not that difficult to exclude confounding factors at all, really.

    It is clear to me now , after reading all the comments , that smoking is good for you . Inhaling the burnt leaves of the tobacco plant is beneficial and holds many nutrients for your body . Especially after the leaves have been heavily altered by the tobacco companies , with many added ingredients , that we don't even know what they are . So as a non-smoker my whole life , I finally see the light....so to speak . I will believe all the people who say smoking is not bad , I will expose my children to the smoke , like they do , and revel in the fact that it is good for them , no matter what the experts say !!!! Thank you smokers !!!

    Steve: No Steve, it's not really much of a leap at all. We are constantly being bombarded with the message that if the child, or "it" is wanted, then "it" is an "unborn baby" and worth all the protections we can afford it, like avoiding even second hand smoke at all costs. Otherwise, "it" is just an "it", and human right to life be damned.

      Because the author of this piece is aiming his narrative at expecting Mothers or those who know them. This is not an abortion issue. It is a study geared towards expecting Mothers, information to consider when planning a child or with child. That's it. Therefore the term Baby. The link for this piece actually says "fetus". The narrative changes for the demographic it is intended to affect.

    I've known people who smoked and died from lung cancer. I quit smoking several years ago because I had another type of cancer, not related to smoking, but once your body learns how to grow that stuff . . . well, I didn't like watching my aunt die that way, so I quit.

    However! My doctor told me that all the following problems would go away if I quit smoking cigarettes:
    1) Coughing up a gob of phlegm every morning.
    2) Shortness of breath.
    3) Post-nasal drip.
    4) Ruddy complexion.
    5) Chronic fatique.
    6) Constant nasal congestion.

    There was more, but you get the idea, right? Guess what: only #2 has cleared up at all; everything else is now blamed on allergies (grasses, weeds, and cats). The only other thing that improved was the range of my singing voice. I'm not saying I'm going to take up smoking again (it just wouldn't make sense given the overall scientific evidence of potential harm), I'm just saying that perhaps some of the evidence is slanted, spun in an anti-tobacco direction. Maybe that isn't a bad thing, but I'm tired of the government giving us more and more rules and laws by which we must abide, and less real information.

      Kate, I think your doctor was misinterpreting statistics. As a physician myself, yes, statistically you are likely to see an improvement in any of the above. Will you individually seen an improvement? If you are on the right statistical side of the equation, if you aren't smoking on top of superimposed allergies that mask any slight improvement, etc. Either you misheard or the physician didn't explain clearly. But, to answer your question, no, there is no slant. You are certainly statistically more likely to see improvement in all of those areas with smoking cessation. Some people confuse statistical likelihoods with absolutes and discredit when it isn't a matter of absolutes.

  15. Nobody N. Particular

    Does any one read these studies, which make these rather bold claims? I mean, what was the sample size, was it statisically significant? Also, list of all the assumptions made regarding this study; in the first study regarding second hand smoke and it's health effect, made the assumption that if you developed lung cancer (or any other lung diseases) and there was a smoker present (at home or at work) then there was a direct relationship between the smoking and the illness. Statisics can only show a correlation between two events, it DOESN'T prove any sort of CAUSE & EFFECT relationship. These assumptions are the foundation of the faulty studies, that and the fact that the details of the statisical sampling method is not include says a lot about the "science" of the study. Now having said that, if I were a parent of a small child (or baby) I would certainly limit the exposure they would have to these things, but not to the point that I would demand that everyone else change for the sake of my child.

    Cigarettes should just be outlawed, period. They stick and smokers' waste is all over the sidewalks and the street. In cold season, they are always the ones who can't shake their colds for weeks and weeks. They smell horrible and they take several long breaks during the workday to get their 'fix'. My mother and I had a very contentious relationship and a large part of that was because she smoked in the house and in the car...with all the windows up. She was a rude smoker and, as a child, when I complained, she would blow smoke into my face. So, I grew up, understandably, with a very anti-smoking point of view. My mother, incidentally, died from lung cancer when long-awaited grandchildren were only 8, 3 and newborn. The look on her face when she looked at them said just what she was thinking. It was heartbreaking. You cannot have a strong, viable, physically, and MENTALLY healthy country when addictive, killer products are available everywhere. It's sick.

    Ok – serious question to smokers – why do you smoke? IComing up with a list of negatives and positives:

    1. You smell gross
    2. you are ruining your health
    3. you are hurting the health of those around you
    4. (some of) you are littering (I've seen gorgeous beaches littered with cigarette butts and it makes me sad!)
    5. You are wasting a lot of money that could be used for much better things (paying off debt, a child's college fund, retirement...)

    and these are the positives I can think of...

    So tell me why you smoke – and not just "because I can". What are good reasons to smoke?

      There are no good reasons to smoke at all. I smoked for two years, and have been 'smober' for five, but I still remember the addiction. It is powerful, and unless you have felt it you really have zero idea or understanding. I hated it every time I would smoke, but my brain and body didn't care.

      The first few days into my quit journey, I would be extremely edgy. I felt as though my body was tingling and had terrible focus. I was cranky and lethargic, and all I could think about was a cigarette. Everything reminds you of it. Speaking of that (everything reminding you of it), I was fighting a habit alongside the addiction. Songs, waking up, coffee, after eating, while driving, etc, were all triggers of the habit.

      Habits and addiction are two very separate yet powerful things. When they are both focused on the same thing, they have a synergistic relationship that no-one but a smoker/ex-smoker knows.

      So there. Not one positive, you are 100% correct.

    The whole smoker bashing thing is just another symptom of our emerging nanny state. I don't need a government or any other organization to tell me what is and isn't good for me. We all KNOW smoking is bad for you, and second hand smoke is probably not good for a fetus. So use your damn god given common sense and smoke outside when wifey is expecting. The last thing I need is somebody telling me what I can and cant do inside my house, I am not incapable of common sense, I can make the decision not to expose people to my habit on my own. If a 17 year old kid can join the military and a woman can abort her child then I can pack my lungs with tar if I want and its MY problem and MY choice to do so.

      you smoke.

      This means – you don't care about rising healthcare costs because smoking is largely to blame for the rise in heart disease and cancer, two of the costliest portions of healthcare which lead to rising insurance premiums

      It also means you don't care about your own health, or your family's health, or other pregnant women's health.

      It also means, statistically, you are uneducated (most smokers, statistically are uneducated and that is a fact).

      Therefore, no I don't believe you have "common sense", statistically you're an uneducated, impulsive buffoon who likes to breathe in over 2000 toxic chemicals simply because "you can". It's pretty sad actually.

      It also makes you smell awful and age quicker. Smokers are actually pretty disgusting.

      "I can pack my lungs with tar if I want it's my problem"

      No it's this country's problem because your idiocy is going to cost everyone else money, since you are knowingly doing something that is going to use more healthcare resources.

      If it was only your problem, when you got lung cancer you'd go and kill yourself. Otherwise, it's not your problem, it's the healthcare system's problem. Since I'd bet my life you don't have 10 grand a week to spend on chemo, you'd either be using insurance (increasing everyone else's premiums by increasing insurance company costs, that is a fact), or you'd be basically stealing from the medical system by going in, getting chemo, and then not paying and allowing the hospital to swallow the cost, raising everyone else's rate.

      And it's not only lung cancer, that goes for lung cancer, heart disease, pulmonary embolism/vascular events/cerebrovascular disease, asthma, COPD/emphysema/chronic bronchitis/pneumonia

      the list goes on. In the end, smokers are selfish, shortsighted buffoons. And they smell.

      So, I'm definitely anti-smoking but, the statistics say that smokers tend to die off younger and therefor are less of a societal burden to us than the obese area anyway. It seems to me that if this is the case, then we should not only ban cigarettes but also pop, Lil Debbie's, candy bars, cookies, etc., to get rid of the obese people who are draining our health care system. In fact, while we're at it, maybe we should ban tylenol and ibuprofen because the over use of them can be bad for you too. Maybe we should also ban salt because that causes high blood pressure. It's a slippery slope folks, a slippery, slippery slope!

      that's a great reason why it should be ok to be exposed to second hand smoke...because it's also bad to be in a room full of car exhaust?? I agree, being around lots of car exhaust is gross, and I like to limit my exposure to it. I would never willingly sit in a tavern full of car exhaust, and I'm pretty sure no one here would! However, cars are functional and it makes sense as to why people use them. Eliminating cars would make it tough for people to go to work, school, to buy food, etc. Limiting smoking would have what negative consequences?? I can't think of one.

Car exhaust is far more dangerous the smoke. When you mention the impact of banning cars, you are just making excuses because you don't want to ban something that affects you.

      I think there are far better examples of freedom in this country than smoking – like say the freedom to practice whatever religion you choose, or the freedom of speech. The freedom to harm yourself and potentially harm others through totally unnecessary means...not so wonderful.

      And banning cars wouldn't actually affect me as much as others. I work from home, and before this I used public transportation. I also often walk to the grocery store. But – I can see that people really need cars, and sometimes I do too. But none of us need cigarettes, and everyone would be better off without them. I do drive a small, low emissions vehicle because I do care about limiting the amount I pollute the country.

    Tobacco should be a controlled class a substance just like cocaine and heroin.

    I don't eat at McDonalds so I demand that everyone else quit eating there. After all, I don't want to be driving on the interstate when one of you has a fast food heart attack and causes a pile up.

    Thanks to the commenters in this section who are trying to explain statistics and scientific research methods to people who prefer the sound-bite approach to science. Anecdotal evidence may make for interesting comments but is basically scientifically worthless most of the time. Combine that with people who are personally affronted when scientific study results threaten their ability to delude themselves about the "safety" of their cigarettes and you have an uphill battle. Keep it up!

    And no alcohol and caffeine, either, of course. In short, pregnant women should be in a clean environment with clean substances. Fragile humans such as babies, pregnant women, elderly people, people with allergies, etc. contribute to the whole population group to stay moderate and safe always.

    Tobacco products , especially cigarettes , are the most heavily tested consumer products on the market today . More so than even food Cigarette companies have some of the most technologically advanced machines to test thier products , because so much care has to be made when producing a product that WILL kill you , that you have to balance how much toxins you allow , how many toxins in each delivery vehicle (cigarette) , and still make them as addictive as possible without killing your target consumers ! They need them around as long as possible to continue consuming thier "products" !

    Smoke"em if you got "O\

    This discussion reminds me of when former California Governor Pete Wilson, on the tobacco cartel's payroll, in defense of tobacco claimed that "even too much milk can be bad for you." Yeah.

    3) Fetal Alcohol Syndrome (FAS) results in mental and physical retardation of the newborn. The incidence of FAS in the United States is 1.9 cases per every 1000 births. Birth defects other than FAS linked to alcohol use are 1 in every 100 births. Statistically these numbers are huge. According to the World Health Organization (WHO), the net rates for FAS are 1 in 500 for US, Canada, Europe and Australia combined. In 1991, The Journal of the American Medical Association (JAMA) reported that FAS (Fetal Alcohol Syndrome) is the leading known cause of mental retardation in Western Civilization (see http://come-over.to/FAS)

    This is one of those studies that concludes the obvious. It seems that the money wasted on this study could have been used to educated ignorant pregnant women about the dangers of second hand smoke and how they should avoid it in order to protect their child. Really, how many women out there are not aware of the dangers of second hand smoke? Cigarettes kill, whether you smoke them or not if you are around people who smoke. Cigarettes are a death industry. They should be outlawed. Or keep raising the taxes on cigarettes until on the wealthy can afford them.

    My loser ex-boyfriend picked up smoking a year or two after we started dating. I did not sign up for dating a smoker, but he somehow slowly became one. I found it to be a really weak habit. He would do it when he was mad, bored, tired, anxious... instead of using smoking to "calm" yourself, why not confront your emotions like an adult?

    With havin so much content and articles do you ever run into any problems of plagorism or copyright infringement? My website has a lot of exclusive content I've either written myself or outsourced but it seems a lot of it is popping it up all over the web without my permission. Do you know any ways to help stop content from being ripped off? I'd genuinely appreciate it.
