Overweight equals healthy study shown to be flawed in many ways

This shows you why you must watch out for the media as their job is to report things that sell rather than report unsexy statistics that tell the truth…

The Medical Express article says: “In January 2013, when the Journal of the American Medical Association published a meta-analysis of 100 studies that probed the relationship between body mass index and mortality—studies that found slightly overweight people have lower all-cause mortality than normal weight and underweight people—media around the globe trumpeted the news”.

“To clear up the confusion, Dean Flier worked with Julio Frenk, dean of the Harvard School of Public Health and the T & G Angelopoulos Professor of Public Health and International Development at HSPH and the Harvard Kennedy School, to convene a panel of experts at HSPH on Feb. 20 to discuss the findings with the HMS and HSPH communities. Flegal, a senior scientist at the CDC’s National Center for Health Statistics, was invited to the event, but did not attend.

"We live in an era of near-ubiquitous access to information,” Dean Frenk said, “but the university has an important role to play in providing context and analysis to help people judge the value of information they are consuming, especially when there are equivocal or controversial findings”.

“The panelists evaluated Flegal’s findings and pointed out a number of methodological errors in the study that they said resulted in the artificial appearance of a protective benefit in being overweight or mildly obese. “When something sounds too good to be true, it’s usually not true,” said Frank Hu, HSPH professor of nutrition and epidemiology and HMS professor of medicine”.
