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”.
