Hookah smoking increases risk of subsequent cigarette smoking among adolescents
2014-12-09
(Press-News.org) A team of researchers at Dartmouth College and University of Pittsburgh found respondents who had smoked water pipe tobacco but not smoked cigarettes were at increased risk of cigarette smoking two years later as recently published online in JAMA Pediatrics. The study followed 2,541 adolescents and young adults for two years.
Samir Soneji, PhD, a tobacco regulatory control researcher at Dartmouth and lead author on the study said, "We found hookah smoking increased the probability of trying cigarette smoking over the next two years by 19%."
This longitudinal study developed at Dartmouth's Norris Cotton Cancer Center followed 2,541 individuals aged 15 to 23 years old for two years, and demonstrated that hookah smoking, which commonly begins as a social custom, and snus use are associated with later cigarette use. Specifically, hookah smoking and snus use among non-cigarette smoking adolescents and young adults were longitudinally associated with subsequent cigarette smoking including initiation of cigarette smoking, cigarette smoking in the past month, and high-intensity cigarette smoking. Snus is a smokeless tobacco product that originated in Sweden and has become popular among young men living in the rural U.S.
Manufacturers of both snus and shisha -- the tobaccos smoked in hookahs -- increase the appeal of their products by adding appetizing flavors and marketing them in social media. Mass media marketing of cigarette products has been banned in the U.S. since 1971 when the Public Health Smoking Act of 1969 went into effect.
What's more, the volume of carcinogen-containing smoke inhaled by a hookah smoker is 100 times that of a smoker smoking a single cigarette.
Looking forward, Soneji encourages comprehensive Food and Drug Administration regulation of all tobacco products to restrict manufacturers' ability to flavor, package, and market their non-cigarette tobacco products in ways designed specifically to appeal to adolescents and young adults. Doing so may curb the onset of cigarette smoking.

The study was supported by NCI grant R01-CA77026, NCATS grant KL2TR001088, and NCI grant RO1-CA140150. In addition to Soneji, collaborators included James D. Sargent, MD and Suzanne E. Tanski, MD, MPH from Dartmouth's Norris Cotton Cancer Center and Brian Primack, MD, PhD from the School of Medicine at University of Pittsburgh.

Drinking or eating from cans or bottles lined with Bisphenol A (BPA) could raise your blood pressure, according to new research reported in the American Heart Association's journal Hypertension.
BPA, a chemical used as an epoxy lining for cans and plastic bottles, is everywhere, and its consumption has been associated with high blood pressure and heart rate variability. Previous studies have shown that BPA can leach into foods and drinks.
"A 5 mm Hg increase in systolic blood pressure by drinking two canned beverages may cause clinically significant problems, particularly ...

Nine in 10 primary care physicians say that prescription drug abuse is a moderate or big problem in their communities and nearly half say they are less likely to prescribe opioids to treat pain compared to a year ago, new Johns Hopkins Bloomberg School of Public Health research suggests.
Primary care doctors also appear to recognize many risks of prescription opioid use, including addiction and death by overdose, according to the findings reported in the Dec. 8 issue of JAMA Internal Medicine.
"Our findings suggest that primary care providers have become aware of the ...

A survey of primary care physicians found the vast majority of practicing internists, family physicians and general practitioners consider prescription drug abuse to be a significant problem in their community and most physicians agreed opioids were overused to treat pain, according to a research letter published online by JAMA Internal Medicine.
Primary care physicians are critical in maximizing the safe use of opioid pain-relieving medications. It is because of this that Catherine S. Hwang, M.S.P.H., of the Johns Hopkins Bloomberg School of Public Health, Baltimore, ...

Smoking water pipe tobacco from hookahs and using the smokeless tobacco snus were associated with initiating cigarette smoking and smoking cigarettes in the past 30 days among previously nonsmoking teenagers and young adults, according to a study published online by JAMA Pediatrics.
The Food and Drug Administration regulates cigarettes, loose tobacco and smokeless tobacco products. However, the FDA does not regulate the manufacturing, distribution and marketing of other tobacco products, such as water pipe tobacco, and many of those products are used by teenagers and ...

Salt Lake City - Develop 100 drugs in 10 years. That's the ambitious goal set by a group of scientists and engineers at the University of Utah, founders of Recursion Pharmaceuticals, a start-up company that is able to quickly and affordably identify unexpected ways a drug could be used by testing it on diseased cells.
The disruptive approach to drug development, aided by custom-designed software capable of tracking changes, or signs of healing, in cells, could speed discovery of therapies for so-called "orphan" diseases.
Scientists at Recursion have already identified ...

(SACRAMENTO, Calif.) -- Children with autism spectrum disorder (ASD) were more than twice as likely to have been exposed in utero to preeclampsia, and the likelihood of an autism diagnosis was even greater if the mother experienced more severe disease, a large study by researchers with the UC Davis MIND Institute has found.
Women with preeclampsia experience hypertension during the latter half of their pregnancies, and may have increased levels of protein in their urine and edema, or fluid retention. Preeclampsia can develop into eclampsia, a life-threatening condition ...

New York, NY, December 8, 2014 - Challenges to global health can evolve from policies and decisions that take years or decades to unfold. An article in the current issue of the Annals of Global Health describes the current state of asbestos use worldwide, a story that began over 100 years ago, and the real and contrived controversies regarding asbestos.
At the peak of asbestos use in 1972 in the United States, more than 775,000 tons of asbestos were used, much of it by the construction trades and shipbuilding industry, in addition to the manufacturing of many consumer ...

There are strong economic incentives for governments to invest in early childhood nutrition, reports a new paper from the University of Waterloo and Cornell University. Published for the Copenhagen Consensus Centre, the paper reveals that every dollar spent on nutrition during the first 1,000 days of a child's life can provide a country up to $166 in future earnings.
"The returns on investments in nutrition have high benefit-cost ratios, especially in countries with higher income levels and a growing economy," said Professor Susan Horton, of the School of Public Health ...

Older Latinos living in the U.S. who perceive their neighborhoods as safer and more walkable are less likely to develop severe depressive symptoms, and the effect may be long term, a new study suggests.
Researchers examined links between the onset of depressive symptoms in 570 older Latino adults and various characteristics of the Greater Los Angeles neighborhoods they lived in, including crime, the availability and quality of sidewalks, traffic safety and aesthetics.
Participants ranged in age from 60 to 90, and 351 of them screened positive for low levels of depression ...

The opioid pain-reliever tramadol appears to be associated with an increased risk of hospitalization for hypoglycemia, a potentially fatal condition caused by low blood sugar, according to a report published online by JAMA Internal Medicine.
Tramadol hydrochloride is a weak opioid whose use has increased steadily worldwide. However, concerns have been raised about the drug and an increased risk for hypoglycemia.
Because of increasing use of the doctor-prescribed pain reliever, researchers at McGill University and the Lady Davis Institute at the Jewish General Hospital ...
