MedicalResearch.com: What is the background for this study?
Response: Blood cholesterol is a critical initiator of atherosclerotic plaques in the arteries that can lead to heart attack in adulthood. It is well established that these changes in the blood vessels occur already in childhood. Thus, it is important to know the status of cholesterol levels in youth to inform public health efforts aimed at preventing cardiovascular disease in the population.
In the US there have been changes in childhood obesity prevalence (which may worsen cholesterol levels), the food supply (such as reduction of trans fats which may improve cholesterol levels), and other factors in recent years.
We therefore designed a study to examine trends in cholesterol levels among youth in recent years.

MedicalResearch.com: What is the background for this study?
Response: There is some mixed evidence regarding whether state level tort reform reduces defensive medicine, or the practicing of medicine in such a way to reduce medical liability. This includes “positive” defensive medicine, or performing certain tests and procedures to reduce such liability. Other research finds that the perception of malpractice risk drives such defensive medicine, including the use of diagnostic imaging, such as CT scans and MRIs.
I was interested in exploring what influenced the perception of this risk, hypothesizing that, for a physician, a report of an injury against one’s colleague might increase the perception of this risk and lead to an increase the use of diagnostic imaging.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Dr. Hoda Magid, my former graduate student, and I wanted to examine whether owning promotional items for e-cigarettes and other non-cigarette products predicted youth use of those products. Other studies have examined whether ownership of coupons, samples, and other promotional materials influenced cigarette use, but no longitudinal study examined other tobacco products.
Our findings show that non-tobacco using youth who own items to promote e-cigarettes and other alternative tobacco products are twice as likely to use alternative tobacco products a year later.
