Do diet patch claims stick? November 16, 2009 ![]() Another well-done "Healthy Skeptic" column - this one about on-the-skin diet patches, their claims, and the lack of published evidence to back up those claims. Our Review Summary
If every news organization in the country had a regular "Healthy Skeptic" column like the Los Angeles Times does, we'd undoubtedly have a lot smarter health care consumer population. They've done it again with this story on slap-'em-on diet patches, and one expert's quote that the product claims are "beyond ridiculous."
Click on Criteria for definitions. We're told how the products are available online or at health food stores. ![]() Discuss costs? - SATISFACTORY
Costs of each product are described. ![]() Avoid "disease-mongering"? - NOT APPLICABLE
The column focuses on the products - not on the problem of overweight - so this criterion is not applicable with this story. ![]() Evaluate the quality of evidence? - SATISFACTORY
The story succinctly quotes one expert saying "There's no evidence" on one product claim. And another expert says "No diet patch has passed muster n a published, peer-reviewed study." ![]() Quantify the potential harms? - SATISFACTORY
We'll give the column a barely passing grade on this because it nailed lack of evidence of efficacy - which can be viewed as a harm. And it stated that "every known appetite suppressant has significant side effects" - although it didn't give details. The fact that there are several competing patches gave an appropriate context. ![]() Quantify the potential benefits? - SATISFACTORY
The story explained the lack of evidence of benefit. It cited evidence claimed for one product on one website but quoted an expert saying the results were suspiciious and not at all convincing. ![]() Appear to rely solely or largely on a news release? - SATISFACTORY
No evidence the story relied on a news release. ![]() Use independent sources and identify conflicts of interest? - SATISFACTORY
Multiple sources were interviewed. ![]() Compare the new approach with existing alternatives? - NOT SATISFACTORY
The story could have at least briefly mentioned other weight loss methods that had evidence to back them up. Total Score: 8 of 9 Satisfactory The U.S. Preventive Services Task Force is considered the gold standard of preventive health recommendations - including on screening tests. It's a good source for journalists and consumers.
About 70% of the stories reviewed from 2006-9 failed to adequately discuss costs, or to explain how big (or small) are the potential benefits and harms of treatments, tests, products and procedures.
We have documented a disturbing trend of news stories taking an advocacy stance, promoting certain screening tests outside the boundaries of scientific evidence.
Stories on new technologies like Cyberknife, DaVinci robotic surgery systems, and proton beam cancer therapy often fail to scrutinize the evidence and/or to discuss the costs involved.
Rather than suggesting that everyone should be screened for everything, news stories could explain: "All screening tests cause harm; some may do good."
