Hospitalizations for heart attacks and strokes declined significantly after Texas city imposes smoking ban



 



A recent study has shown that not only did heart attacks and strokes decline significantly in all residents of a Texas city after a citywide smoking ban, but that hospitalizations for chronic obstructive pulmonary disease (COPD) and asthma also dropped for some.

The study compared hospital discharge rates from July 2004 through June 2006 (before the ban) with discharge rates from July 2006 through June 2008 (after the ban) in Beaumont, Texas. These rates then were compared with hospital discharge rates in Tyler, Texas, which did not have a smoking ban at that time.



Using hospital discharge data – which includes each patient’s diagnosis – enabled researchers to measure changes in the frequency of several tobacco-related illnesses, said Debra Cherry, MD, with UT Health Northeast and one of the study’s authors.

COPD, asthma hospitalizations in whites fell after ban

After Beaumont’s smoking ban, hospitalization rates declined for African-Americans, whites, and individuals in both groups diagnosed with heart attacks and strokes. Heart attack hospitalizations dropped 26 percent and hospitalization for strokes decreased by 29 percent, the study said.

Hospitalizations for COPD and asthma also declined for whites, though not for African-Americans. The number of whites discharged with a diagnosis of COPD fell by 36 percent, while the number of whites discharged with an asthma diagnosis fell by 31 percent.

Hospitalization rates in Tyler stayed the same for all the diagnoses except for stroke, which declined 30 percent, Dr. Cherry said. But in Beaumont, hospitalizations for stroke in the non-Hispanic population declined 20 percent more than in Tyler after Beaumont’s ban began.



Texas one of last state’s without smoking ban


“While other studies have shown a similar drop in heart attacks after a smoking ban, this is one of the first to show a racial disparity in health benefits, as well as a decline in tobacco-related diagnoses other than heart attacks,” said Dr. Cherry, an associate professor of occupational medicine at UTHSCT.

“Texas is one of the last states without a statewide-smoking ban. If we had one, we could potentially reduce hospitalization rates for tobacco-related illnesses by a third. That would mean considerable savings, because the cost of caring for people with tobacco-related hospitalizations is quite expensive,” she said.

It’s likely that hospitalizations dropped because non-smokers were protected from second-hand smoke, Dr. Cherry added.

Study published in CDC’s lead online journal

“Air pollution from tobacco smoke may trigger heart attacks, strokes, and breathing problems in non-smokers while the cleaner air in smoke-free environments seems to be associated with a decline in these types of problems,” she said.

The study’s authors don’t know why the ban lowered COPD and asthma discharge rates in whites but not in African-Americans. However, national studies have shown that African-Americans who are smokers smoke less, on average, than do whites, Dr. Cherry said.

The study was published in the lead online journal published by the Centers for Disease Control and Prevention, Preventing Chronic Disease: Public Health Research, Practice, and Policy.

For more than 60 years, UT Health Northeast has provided excellent patient care and cutting-edge treatment, specializing in pulmonary disease, cancer, heart disease, primary care, and the disciplines that support them. UT Health Northeast’s annual operating budget of $138.8 million represents a major economic impact of over $347 million for the Northeast Texas region. Since 2002, scientists in the Center for Biomedical Research have been awarded more than $120 million in research dollars. As the academic health science center for Northeast Texas, its graduate medical education programs – with residencies in family medicine and occupational medicine – provide doctors for many communities throughout the region and beyond. UT Health Northeast is also the program sponsor of the residency program in internal medicine at Good Shepherd Medical Center in Longview.

Have you any idea how much this constant drip feed of junk science to support a failing campaign to eliminate smokers is damaging the reputation and trust in medical services, science and politics? The old mantra of 'keep repeating the lie and eventually it will be believed' may have worked in Hitlers day but people are much more aware now.

Use some common sense and look at the absurd claims; The suggestion is that the ONLY reason for heart attack reduction is the smoking ban?

Nothing to do with better treatment, The widespread use of medication to control cholesterol and hypertension etc? What is the point of that if merely quitting smoking solves the problem -we can stop wasting $Billions on this medication then eh? In fact heart disease is the BIGGEST killer of never smoking males over 50 and females over 60yrs in US - so how can it be deemed a 'smoke related' disease or related in any way to smoke bans?

The suggestion is that bans make people quit but we know that invariably bans have halted the decades long decline in smoking. I suspect this to be the case here too, but no mention is made of how much smoking has reduced or increased; Is this not very relevant?

So it must be SHS exposure reduction eh?

SHS is HARMLESS - the 'harm' was invented to sidestep valued principles of individual liberty, as defined by John Stewart MILL many years ago, and to facilitate a means to justify coercive bans, frighten and CONTROL people. This was anti-smokers BIG mistake, so blatantly wrong that it motivated many to re-assess other anti-smoker rhetoric - and found it wanting!

if you look closely, you will find that pretty much EVERYTHING claimed by anti-smokers is based on propaganda designed to CONTROL individual behaviour to serve a pre-determined agenda.

But there is more;

Asthma increased the most when smoking REDUCED the most in the 70's, 80's and 90's!

Most Cancers are STILL INCREASING and most are in NON smokers - 80% of new lung cancers in US are diagnosed in NON smokers now!

The cat is out of the bag and hopefully those professionals with integrity, and there are still many, will call a halt to this madness, before belief in science and medicine is reduced to the level of 'Hell and Damnation' style religion.

No wonder so many people do not believe what so called tobacco control is selling anymore.The "science" used here is mere data mining.(junk to create an excuse to do something)

Tobacco smoke has yet to be shown to cause "heart attacks" so claiming these have decreased is irrelevant.Besides,if exposure to tobacco smoke was the cause in non-smokers,then this rate should have been showing declines several decades ago as smoking rates fell.Perhaps earlier claims have been conveniently forgotten.Smoking cessation was supposed lead to an immediate risk decrease with 50% less risk for smokers after the first year of quitting.

You cannot take a one time result in one or more locales and try to claim causation.(reminds me of Helena or Scotland) This study should reinforce what has been written above;

Changes in U.S. hospitalization and mortality rates following smoking bans

Abstract

U.S. state and local governments have increasingly adopted restrictions on smoking in public places. This paper analyzes nationally representative databases, including the Nationwide Inpatient Sample, to compare short-term changes in mortality and hospitalization rates in smoking-restricted regions with control regions. In contrast with smaller regional studies, we find that smoking bans are not associated with statistically significant short-term declines in mortality or hospital admissions for myocardial infarction or other diseases. An analysis simulating smaller studies using subsamples reveals that large short-term increases in myocardial infarction incidence following a smoking ban are as common as the large decreases reported in the published literature. © 2010 by the Association for Public Policy Analysis and Management.

Asthma etc. seems to be adequately covered.What could be added is that the cause of it is unknown. Pet dander and pollen are still the main triggers though.

This explains it and I can see why you wouldnt want to admit it!

In 2008 this paper was produced in America and concludes that nictotine and hence active smoking and passive smoking leads to less asthma. It also gives the aetiology (causation) why nicotine and the biologial process that reduces asthma in recipients.

The results unequivocally show that, even after multiple allergen sensitizations, nicotine dramatically suppresses inflammatory/allergic parameters in the lung including the following: eosinophilic/lymphocytic emigration; mRNA and/or protein expression of the Th2 cytokines/chemokines IL-4, IL-5, IL-13, IL-25, and eotaxin; leukotriene C4; and total as well as allergen-specific IgE. unequivocally show that, even after multiple allergen sensitizations, nicotine dramatically suppresses inflammatory/allergic parameters in the lung including the following: eosinophilic/lymphocytic emigration; mRNA and/or protein expression of the Th2 cytokines/chemokines IL-4, IL-5, IL-13, IL-25, and eotaxin; leukotriene C4; and total as well as allergen-specific IgE. ”

The inconvenient truth is that the only studies of children of smokers suggest it is PROTECTIVE in contracting atopy in the first place. The New Zealand study says by a staggering factor of 82%.

“Participants with atopic parents were also less likely to have positive SPTs between ages 13 and 32 years if they smoked themselves (OR=0.18), and this reduction in risk remained significant after adjusting for confounders.

The authors write: “We found that children who were exposed to parental smoking and those who took up cigarette smoking themselves had a lower incidence of atopy to a range of common inhaled allergens.

“These associations were found only in those with a parental history of asthma or hay fever.”

They conclude: Our findings suggest that preventing allergic sensitization is not one of them.”

This is a Swedish study.

“Children of mothers who smoked at least 15 cigarettes a day tended to have lower odds for suffering from allergic rhino-conjunctivitis, allergic asthma, atopic eczema and food allergy, compared to children of mothers who had never smoked (ORs 0.6-0.7)

CONCLUSIONS: This study demonstrates an association between current exposure to tobacco smoke and a low risk for atopic disorders in smokers themselves and a similar tendency in their children.”

Heart miracles are impossible

It's good to see Dr. Carl V. Philips back and blogging over at Ep-ology. In his last two posts he has been discussing the North Carolina heart miracle 'study', which is as bad a piece of advocacy-driven junk science as you will ever see.

In particular, he makes a point which I have tried to made before, which is absolutely fundamental to all the heart miracle studies. The results they report—of heart attacks falling by 17%, 21%, 40% or whatever—are simply impossible.
