Peer review of paper drafts

As we discussed in class on Tuesday, you are required to read and provide constructive feedback on the drafts of research papers written by members of your peer response group. Your feedback is due to members of your group and to me by Tuesday, Nov. 20.

Here I am posting the form you should use in reviewing each other’s work. Most word processing software can open this file. If you have problems, please post a comment below.

For each paper you review, please add your comments in response to each question and send the final version to the author and to me as an email attachment by Nov. 20.

Is overweight a misnomer?

A few weeks ago, we discussed a paper published in 2005 showing that people who are defined as overweight (BMI of 25-<30) actually have the lowest risk of mortality. Today, a new paper sheds more light on the association between BMI and mortality by looking at specific causes of death.

It turns out that people who are officially defined as overweight have a lower overall risk of mortality because they are less likely to die from diseases like Alzheimer’s, infections, and lung disease. At the same time, being overweight (but not obese) does not appear significantly to increase the risk of dying from cancer or heart disease.

In a New York Times story about this paper, several observers echoed some of our discussion in class:

Some who studied the relation between weight and health said the nation might want to reconsider what are ideal weights.

“If we use the criteria of mortality, then the term ‘overweight’ is a misnomer,” said Daniel McGee, professor of statistics at Florida State University.

“I believe the data,” said Dr. Elizabeth Barrett-Connor, a professor of family and preventive medicine at the University of California, San Diego. A body mass index of 25 to 30, the so-called overweight range, “may be optimal,” she said.

But as some of you suggested in class, mortality isn’t the only relevant outcome. Others argue that people who are overweight are more likely to develop heart disease, diabetes, and other conditions even if they are not more likely to die prematurely as a result.

On that note, another paper in today’s issue of JAMA examined self-reports of disability among people of varying weights at two points in time. They show that people defined as obese (BMI ? 30) are more likely to be disabled and that the disability gap between people in the obese and normal-weight categories has increased over time. But this finding appears to hold only for the obese category. People with BMIs in the range of 25-30—officially overweight—do not report higher levels of disability.

Paul Farmer on video

Earlier this month, Paul Farmer delivered a keynote address at the Heller School for Social Policy and Management at Brandeis University. The Heller School has posted a video of Farmer’s speech online, so you can see it too.

The talk focuses on the policy implications of global inequities in health. You will recognize the core arguments from our discussion of Infections and Inequalities, but the examples and evidence come largely from Farmer’s work since that book was published. (Those of you who attended Tracy Kidder’s talk two weeks ago will also recognize some of the photos.)

The best part, if you ask me, is the question and answer period — so hang in there through the end. What aspects of the talk do you find most compelling? In what ways does Farmer draw on his training in anthropology, not just in medicine?
