Andrea Wiley and John Allen present many interesting topics in
Chapter Five. The one that I found most relatable to my life was the discussion
of size and weight, especially in terms of overweight and obese children.
In our society, talk of weight loss and weight gain are
prevalent almost everywhere. There are diet ads on the radio, TV, and computer;
there are entire shows that focus on weight loss (i.e. “The Biggest Loser”).
Talk of weight loss or dieting will happen in almost any conversation with an
adult. But children are a different story. The authors of this article discuss
how childhood obesity is much more of a problem in rural areas, due to the lack
of adequate and nutritious food, as well as activities to keep children active—all
arguments that are commonplace. This struck a chord with me personally. In this
case alone, the adults investigating this so-called epidemic are basing their
measurement of children’s general health on weight and the BMI scale alone. The
problem with this is that BMI only measures the relationship between weight and
height. It doesn’t take into account muscle mass, bone density and structure,
or even differences between men and women. I have watched so many people
struggle with their weight and base it off this scale alone, not taking into
account any other measurements of health; a perfectly healthy individual could
be overweight or even obese on this scale and vice versa. So, while reading
this, I personally did not agree with what the researchers were doing.
Beyond that, however, the article mentions something that I
was pretty confused about. It states that rapid growth is associated with rapid
rate of cell turnover, which can lead to rapid reproduction of malignant (i.e.
cancer) cells. The article says that this may be associated with a specific
protein that assists in growth. What I don’t understand is that the article
then draws the conclusion that height is positively associated with a risk of
cancer. They cited a study that proves this, but when you hear about cancer
prevention, it is never mentioned that taller people are at a higher risk. I am
skeptical of this and can’t help but wonder if there’s a confounder in that
correlation somewhere.
I have to disagree with you. The cancer development mechanism described makes perfect sense (more cells = greater cancer probability). It may not be widely talked about for many possible reasons, ranging from not being researched enough up to blatant concealation for somebody's benefit.
