One in 10 Americans screened said they sometimes smoked, study found
Newswise, May 4, 2017 – Social smokers’ risk for high blood pressure and high cholesterol is identical to those who light up every day, new research has found.
This large, nationally representative study is the first to look at blood pressure and cholesterol in social smokers. More than 10 percent of 39,555 people surveyed said they were social smokers, meaning they didn’t smoke every day. That’s on top of the 17 percent who called themselves current smokers.
Among current and social smokers (after researchers adjusted for differences in factors including demographics and obesity), about 75 percent had high blood pressure and roughly 54 percent had high cholesterol.
“Not smoking at all is the best way to go. Even smoking in a social situation is detrimental to your cardiovascular health,” said lead author Kate Gawlik, assistant professor of clinical nursing at The Ohio State University.
“One in 10 people in this study said they sometimes smoke, and many of them are young and already on the path to heart disease,” she said.
Smoking is a risk factor for unhealthy blood pressure and cholesterol and both are significant contributors to cardiovascular disease, the leading killer of men and women worldwide.
The study appears in the American Journal of Health Promotion
“These are striking findings and they have such significance for clinical practice and for population health,” said study senior author Bernadette Melnyk, dean of Ohio State’s College of Nursing and chief wellness officer for the university.
Melnyk said doctors and nurses should strive to identify social smokers and offer them advice and tools to quit smoking.
“This has been a fairly neglected part of the population. We know that regular smoking is an addiction, but providers don’t usually ask about social smoking,” Melnyk said.
“The typical question is ‘Do you smoke or use tobacco?’ And social smokers will usually say ‘No’.”
Participants in the study were screened from February 2012 to February 2016 as part of Ohio State’s Million Hearts educational program. The U.S. Department of Health and Human Services in 2012 launched Million Hearts, a five-year initiative to improve cardiovascular health co-led by the Centers for Disease Control and Prevention and the Centers for Medicare & Medicaid Services. Ohio State was the first university-wide partner.
During the screenings, participants identified themselves as nonsmokers, current smokers or social smokers. The screenings also included measures of blood pressure and total cholesterol.
Social smokers in the study were more likely to be younger (between 21 and 40 years old), male and Hispanic. After the researchers took into account demographic and biometric differences between the smokers and social smokers in the study, they found no difference in the risk of hypertension or high cholesterol.
Social smokers were defined as those who do not smoke cigarettes daily, but who smoke in certain social situations regularly.
The good news about this study is there’s plenty of room for intervention and prevention of future death and disease, the researchers said.
“Simple healthy lifestyle behavior changes including appropriate aspirin therapy, blood pressure control, cholesterol management, stress management and – very importantly – smoking cessation can do away with much of the risk of chronic disease,” Melnyk said.
The percentage of participants who called themselves “current smokers” was in line with estimates from the CDC, which reports that 17.8 percent of U.S. adults identify as smokers.
Gawlik and Melnyk said those who consider themselves social smokers should be aware that the toll on their cardiovascular health could be just as great as if they smoked every day.
And this study should prompt clinicians to rethink how they ask patients about smoking, they said.
“Are you a smoker?” isn’t likely to work with social smokers, because they don’t think of themselves as addicted, Gawlik said.
In the study, the researchers advise asking “Do you ever smoke cigarettes or use tobacco in social situations such as at bars, parties, work events or family gatherings?”
Another option: “When was the last time you had a cigarette or used tobacco with friends?”
Furthermore, clinicians working with smokers should be aware that cutting back on smoking isn’t a good answer from a heart-health perspective.
“Doctors and nurses need to educate patients that social smoking is still a major health risk and is not a long-term healthy choice,” Gawlik said.
Limitations of the study include the fact that the researchers don’t have information about prior smoking behavior, just what the participants reported at the screenings. In addition, the screenings were open to people who chose to participate, meaning the study subjects were self-selected.
Gawlik said she’d like to know more about how many of those who smoke socially go on to become everyday smokers.
“That’s a huge area for clinical intervention because you might be able to reach them before they’re completely and totally addicted,” she said.
Ohio State has led a national effort through Million Hearts, which now has over 150 participating organizations and universities, to provide free education and support to health care providers, students and community members looking to reduce cardiovascular death and disease.

People with intermittent explosive disorder at five times greater risk for substance abuse than those who don’t display frequent aggressive behavior
Newswise, May 2, 2017 — People with intermittent explosive disorder (IED)—a condition marked by frequent physical or verbal outbursts—are at five times greater risk for abusing substances such as alcohol, tobacco and marijuana than those who don’t display frequent aggressive behavior, according to a new study by researchers from the University of Chicago.\
In the study, published Feb. 28, 2017 in the Journal of Clinical Psychiatry, Emil Coccaro, MD, and colleagues analyzed data from more than 9,200 subjects in the National Comorbidity Survey, a national survey of mental health in the United States.
They found that as the severity of aggressive behavior increased, so did levels of daily and weekly substance use. The findings suggest that a history of frequent, aggressive behavior is a risk factor for later substance abuse, and effective treatment of aggression could delay or even prevent substance abuse in young people.
IED affects as many as 16 million Americans, more than bipolar disorder and schizophrenia combined. It is often first diagnosed in adolescents, some of whom are as young as 11, years before substance abuse problems usually develop.
IED runs in families and is thought to have a significant genetic component, although Coccaro said people tend to treat it as a social-behavioral issue instead of as a true neurobiological disorder.
“People don’t see this as a medical problem. They think of it as simply bad behavior they have developed over the course of their lives, but it isn’t. It has significant biology and neuroscience behind it,” said Coccaro, who is the Ellen C. Manning Professor of Psychiatry and Behavioral Neuroscience at UChicago.
Previous research has implied that aggressive behavior in IED is due to the presence of other psychiatric disorders, such as anxiety or depression. But the new UChicago study found no such relationship.
While substance abuse, like excessive drinking, can clearly make aggressive behavior worse, the onset of IED almost always precedes the development of chronic substance abuse. Coccaro and his team found that IED preceded substance abuse in 92.5 percent of the cases where subjects developed both disorders.
Coccaro emphasized that early psychological intervention, medication and cognitive therapy are the most effective treatments to prevent, or at least delay, substance abuse problems in adolescents diagnosed with IED.
“What you’re really treating is the emotional dysregulation that leads to aggression,” Coccaro said. “The earlier you treat this dysregulation, the more likely you are to offset other disorders that come later down the road.”
The study, “Intermittent Explosive Disorder and Substance Use Disorder: Analysis of the National Comorbidity Survey Replication Sample,” was supported by the National Institute of Mental Health. Additional authors include Jennifer Fanning, PhD, and Royce Lee, MD, both from the University of Chicago.
Newswise, May 2, 2017– Alcohol consumption is known to be a risk factor for breast cancer based on studies predominantly done in white women. Now a University of North Carolina Lineberger Comprehensive Cancer Center study has found the same risk exists for black women, an understudied group.
Researchers found in the new study that black women who drank more than 14 alcoholic drinks per week had a significantly higher risk of invasive breast cancer than those who drank less.
The findings, published in the journal Cancer, Epidemiology, Biomarkers & Prevention, confirmed the link between alcohol consumption and breast cancer risk, which has been seen in other studies drawn from majority white populations.
And while some breast cancer risk factors - like age or genetics -- aren’t easily modified, alcohol consumption is one risk factor that women, regardless of race, can change to potentially lower their cancer risk.
“Minority groups are often understudied because they represent a smaller proportion of study populations. This work avoided that limitation by working with a consortium of many different studies, including more than 20,000 black women,” said Melissa Troester, PhD, a member of UNC Lineberger and professor of epidemiology in the UNC Gillings School of Global Public Health.
“We found that the patterns observed in other studies examining alcohol and breast cancer risk hold in black women, too.”
The researchers analyzed data for 22,338 women from the African American Breast Cancer Epidemiology and Risk (AMBER) consortium, which combines data from four large breast cancer studies.
Researchers evaluated alcohol as a risk factor for invasive breast cancer as well as for specific breast cancer subtypes, such as estrogen receptor positive or negative cancer.
“Our study demonstrated there is benefit in creating consortia to focus on understudied groups,” said the study’s first author Lindsay Williams, a graduate research assistant at UNC Gillings.
When they studied the data across all breast cancer subtypes, they found consuming seven or more alcoholic drinks per week was linked to increased risk of breast cancer across all subtypes.
Women who previously drank alcohol, and later stopped, had lower risk than women who reported recent use – indicating that women may be able to reduce their risk by drinking less.
However, they did find significantly higher risk for some women who have never drank alcohol.
The researchers said that the group of women that avoids alcohol also sometimes includes women who have other health conditions, and some of these health conditions can increase risk for breast cancer. The finding may direct additional research.
“In the future, it may be worth-while to better characterize women who identify as never drinkers to understand reasons for abstaining from alcohol,” Williams said.
The researchers underscored that the study is important as alcohol consumption can be changed or addressed.
“Overall, our findings among African American women mirror those reported in the literature for white women, namely that high levels of alcohol intake – more than one drink per day – are associated with increased breast cancer risk,” Troester said.
“Alcohol is an important modifiable exposure, and women who are concerned about their risk of breast cancer could consider reducing levels of exposure.”
