We have written before about patients with type II
diabetes having better life expectancy when overweight compared to “ideal”
weight or underweight patients. A study out of the Feinberg School of Medicine,
Northwestern University, Chicago, monitored over 2,600 people with type II
diabetes. They found that overweight people (surprisingly) out lived their
thinner counterparts. The difference in mortality rate was a shocking two to
one.
The new study in Sweden tracked data from over 64,000
adults who had been diagnosed with angina or heart attacks (technically called
acute coronary syndromes). The participants were monitored over a period of
about 21 months, on average.
The participants were divided into groups, based
on their body mass index (BMI). The mortality rate of each BMI group was
compared at the end of the study. The groups with the lowest (underweight) and highest (morbidly obese)
BMIs were the most likely to die. The least likely to die was the group in the
overweight/obese category.
What does this mean? Should people try to gain weight
immediately upon receiving a diagnosis of acute coronary syndrome? Certainly
not based in this one study! The research merely indicates a correlation
between lowered mortality and obesity. There has not been a “cause and effect”
connection established. What does seem reasonable, though, is to question the
knee-jerk reaction to lose a lot of weight in response to such a diagnosis.
More research is required, and we will bring you the
results as they are published. Until then, live a healthy lifestyle but don’t
fixate on achieving the lowest possible BMI.
