 Researchers said the extra exposure to e-cigarette marketing, if not
curtailed by regulation and countered by public health messages,
could lead more youth to start using the devices.
“It appears that youth are being exposed to a sustained level of
marketing about the benefits of e-cigarettes,” said Jennifer Duke,
the study’s lead author from the nonprofit research organization RTI
International in Research Triangle Park, North Carolina. “In
television, that can be influential.”
E-cigarettes were first introduced in China in 2004. The
battery-powered devices let users inhale nicotine-infused vapors,
which don't contain the harmful tar and carbon monoxide in tobacco
smoke.
Concerns about use of the devices by teens and young adults include
the possibility that nicotine could harm developing brains, that the
safety of the inhaled vapors has not been established and that
nicotine use could lead to smoking traditional cigarettes.
“I think - as a potential gateway to future use - this could
potentially cause public health harm,” Duke said.
Unlike traditional cigarettes and other tobacco products,
e-cigarette advertisements are not subject to federal regulations.
The proportion of young people who report ever having used
e-cigarettes is already growing. The number more than doubled from
about 3 percent in 2011 to about 7 percent in 2012, Duke and her
colleagues write in the journal Pediatrics.
“We thought it was important to look at trends in advertising,” she
said.
By analyzing data from the Nielsen ratings company, the researchers
looked for patterns in e-cigarette marketing from January 2011 to
September 2013.
To estimate young people’s exposure to e-cigarette advertising, they
used Nielsen's system of target rating points, or TRPs, which
measure the portion of a specific population within a TV
commercial’s total audience that saw an ad.
For example, a commercial with a 50 "youth TRP" may have been viewed
five times by 10 percent of the youth audience or once by 50 percent
of that audience in a given period.
From 2011 through the first half of 2012, e-cigarette ads had fewer
than 100 TRPs among kids between the ages of 12 and 17 years old.
That rose and peaked at 347 TRPs from April to June 2013 before
declining to 275 TRPs by September.
During the same period in five specific target markets, including
Columbus, Ohio and Raleigh-Durham, North Carolina, youth TRPs for
e-cigarette ads were over 1,000.
The national numbers could mean that 50 percent of all kids in that
age group saw 21 e-cigarette ads from October 2012 to September
2013, the researchers write. Or, it could mean 80 percent of
adolescents saw 13 ads during that time.
The increase over the entire study period represents a 256 percent
rise in TRPs for e-cigarette ads between 2011 and 2013.
The researchers found that more than three quarters of the ad
exposure occurred on cable networks, including Country Music
Television, Comedy Central, TV Land and VH1.

For young adults between the ages of 18 and 24 years, the TRP
numbers were even greater than for adolescents, and represent a 321
percent increase in exposure from 2011 through 2013.
The increased exposure among teens and young adults was largely
driven by an ad campaign from one brand of e-cigarettes known as blu
eCigs, which is owned by the cigarette manufacturer Lorillard Inc.
“We have proactively set limitations on when and where blu eCigs can
be marketed in an effort to minimize any potential exposure to
minors, a part of our criteria is to screen all marketing
opportunities to ensure that our TV ads only run with media
targeting an adult audience of 85 percent or greater,” blu eCigs
told Reuters Health in a statement.
In a perspective piece published in the same journal, Drs. Emily
Duffy and Brian Jenssen from the Children’s Hospital of Philadelphia
called for more oversight of the e-cigarette industry.
“There’s really nothing controlling the quality or the safety of
these products,” Duffy, a pediatrician, told Reuters Health. “I
think it just makes sense that in any situation when there is a
product being marketed that has a potentially addictive or harmful
substance, it really makes sense for an organization like the (U.S.
Food and Drug Administration) to regulate these items.”
A 75-day comment period for e-cigarette regulations that FDA
proposed in April is currently in effect. In May, a group of urban
health officials urged FDA to regulate e-cigarettes more like
traditional tobacco products, including restrictions on ads (see
Reuters article of May 1, 2014, here: http://reut.rs/1hoccAN).
“For parents, it’s important to try to maintain a dialogue with
their children on the risks of any substances – particularly with
e-cigarettes, because there is so much that’s unknown about them,”
Duffy said.
Duke thinks some regulation of e-cigarette ads is needed or the
situation will likely remain unchanged.
“I think if current trends continue, e-cigarette use among youth and
young adults will continue to rise,” she said.
