Times Change, Our Bodies Change, And Now The Body Mass Index (BMI) Guidelines May Change Too

A recent news story in the Journal of the American Medical Association (JAMA) reminds me that lots of things in our lives are changing these days, not the least of which is the shape of our bodies.

Oh, my. This aging thing isn’t so easy, and that is really the message behind Rita Rubin’s timely piece about shifting body mass and muscle as we age and its implications. Although focused on women, I can attest personally that men fall into the same trap as well. That 250 pounds when you are older simply is not the same 250 pounds when you were in college. Now 250 pounds looks more like 280—even though the scale still says 250. Go figure…

Although I may be trying to provide a little humor to the subject, the reality is it’s not humorous when it comes to our health. As we age, muscle turns to fat. In a process called “sarcopenia,” muscle begins an inexorable march to become fat, and for most of us it doesn’t make too much difference how much we try to forestall the shift. It is programmed into our bodies, and although exercise might help, Mother Nature simply doesn’t … Continue reading →

A Real News Story Of Hope: Impressive Decline in Melanoma Incidence In Young Women Will Result In A World With Less Cancer

A recent research report on melanoma from the Centers for Disease Control and Prevention received virtually no notice, yet one of the statistics in that report was—at least for me—stunning, and marked a rare public health win.

People in public health know all too well the gap between educating people about cancer risks and seeing actual results. Skin cancer is no different: We have known for many years that the risk of skin cancer is related to exposure to UV radiation, either from the sun of for indoor tanning.

Yet despite widespread efforts to educate people about this very real cancer risk, we haven’t made much progress reducing its frequency—at least until now.… Continue reading →

FDA Approves Consumer BRCA Test, And We Take Another Step Into The Brave New World Of Genomics

The approval by the Food and Drug Administration of 23andMe’s BRCA test is bound to create a discussion about the merits and pitfalls of direct to consumer genetic testing for cancer risk.

It is also going to add fuel to a growing fire about how we as a nation assess genetic risks for cancer, and whether society is prepared for what is inevitably going to become a genomic-influenced and informed culture of health.

From my perspective, as someone who has given considerable thought to these questions over the past several years, there are no easy answers.… Continue reading →
