NOTE TO READERS: When this project lost substantial funding at the end of 2018, I lost the ability to continue publishing criteria-driven news story reviews and PR news release reviews - once the bread-and-butter of the site going back to 2006. The 3,200 archived reviews, while still educational, are getting old and difficult for me to technically maintain on the back end of the website. So I am announcing that I plan to remove these reviews from the site by April 1, 2021. The blog and the toolkit - two of the most popular features on the site - will remain. If you wish to peruse the reviews before they disappear, please do so by the end of March 2021. After that date you may still be able to access them via the Internet Archive Wayback Machine - https://archive.org/web/.

Overweight teens and liver disease: Is there a link?

Our Review Summary

This Good Morning America segment on fatty liver disease in children fails nearly all measures of quality health journalism.

1. It is plainly derivative of an AP story on the same topic. The AP story, while it has the virtue of more reporting and detail, is itself not solidly grounded on high quality data or research. The GMA segment essentially enlists the network’s medical editor in interpreting a weak work of health journalism by others. 

2. The segment presents no evidence or sources. 

3. The segment four times mentions liver transplants, a fearsome procedure which carries serious questions about cost, fairness, personal responsibility and risk of death. Yet there is nothing other than an unnamed source’s speculation to justify raising this possibility. The effect is to inaccurately and unfairly generate a very high level of anxiety in the parents of overweight and obese kids.

A responsible report on this topic might have said that with so many kids being overweight and obese, parents should be aware of the risk of fatty liver disease. It would have suggested routine blood tests, as many pediatric experts now recommend. The segment could have described the condition a bit and provided information about symptoms, testing, diagnosis, and prevention. It would have mentioned that in rare cases that go undiagnosed, it could lead to liver failure, whose only treatment is transplant. 

But then, that wouldn’t call for an "important medical alert" on the morning news.  

Criteria

Does the story adequately discuss the costs of the intervention?

Not Satisfactory

The segment discusses diagnostic tests for fatty liver disease as well as treatment for end-stage liver disease, which is transplant.

As a matter of course, these costs should be reported.

Does the story adequately quantify the benefits of the treatment/test/product/procedure?

Not Satisfactory

Two specific approaches are discussed – and the benefits for neither are quantified:  liver transplants, and liver testing including biopsies.  A third approach was discussed but not quantified.  The story stated, "There are some studies that suggest that if you lose weight in the early stages of fatty liver, the fat in the liver will start to disappear." But no evidence was provided. 

Does the story adequately explain/quantify the harms of the intervention?

Not Satisfactory

Two specific approaches are discussed – and the harms for neither are discussed:  liver transplants, and liver testing including biopsies.  The statement and recommendation – "that our children are obese. Start worrying about that" – also carries the potential harm of anxiety and over-reaction, when the story didn’t always differentiate between overweight and obesity. 

Does the story seem to grasp the quality of the evidence?

Not Satisfactory

The segment presents no evidence that demonstrates fatty liver disease in children and teens is increasing or that it is leading to more transplants. In a story likely to produce fear, evidence to defend the assertion is particularly important. 

 

Does the story commit disease-mongering?

Not Satisfactory

By offering an "important medical alert" that four times mentions the possible increase in liver transplants, the segment exaggerates the gravity and urgency of childhood fatty liver disease. So does the comment that the problem is "much more urgent". . .than "childhood diabetes." 

The segment does not identify differing risk levels between overweight and obese youth, likely exaggerating the risks to overweight children.  

It’s true that many kids are overweight or obese, and that obesity is a risk factor for fatty liver disease. It’s also true that fatty liver disease can trigger more serious liver disease. 

But the idea that the disease is rampant, rising and driving the need for pediatric liver transplants is all inference and speculation.

Does the story use independent sources and identify conflicts of interest?

Not Satisfactory

The segment names no sources.

The segment includes the following attributions and references: "doctors say" "we worry," "we are learning" and "many experts."

One unnamed expert is quoted as making a prediction–that "fatty livers in kids and teenagers today will become the leading cause of liver transplants by the year 2020"–whose specificity adds to the sense of alarm. Yet he or she is never named. 

Does the story compare the new approach with existing alternatives?

Satisfactory

The segment correctly states that treating obesity and overweight in kids and teens can reduce risk for fatty liver disease, which in turn can reduce risk for more serious liver disease.

The segment does a responsible job of mentioning the improved likelihood of weight loss if the entire family participates in the healthy eating and exercise lifestyle required. 

The segment should have mentioned that in addition to overweight and obesity, it appears that diabetes, high triglycerides, hypertensions and high cholesterol may be risk factors for more medically severe fatty liver disease in children and teens.

Does the story establish the availability of the treatment/test/product/procedure?

Satisfactory

The treatments suggested–diagnosis with a series of blood tests and other tests, plus lifestyle modification to slow or reverse disease, are all easily available and this is implied in the story.

Liver biopsies and of course transplants are available only at specialized centers. 

Does the story establish the true novelty of the approach?

Not Applicable

No claims were made about the novelty of treatment for fatty livers in children – only vague claims about this new trend.

Does the story appear to rely solely or largely on a news release?

Not Applicable

There is no press release linked to this segment. But the broadcast clearly borrows heavily from an Associated Press report that was published three days before this segment aired.

The AP report itself is based on very little information beyond anecdotes–there does not appear to be a major study, consensus statement or dependable new data to hang it on. That story says it is based on "a surge of medical studies" it does not cite and AP interviews with medical experts.

The TV broadcast does not appear to add any reporting to the AP story other than the comments by the medical editor. This adds to the likelihood that the TV segment is based on the AP story rather than independent reporting. 

Curiously, the AP says "many experts" predict fatty liver disease developed in childhood will become a leading cause of liver transplants by the year 2020. In the TV segment, this has been reduced to "one expert."

Total Score: 2 of 8 Satisfactory
