The Vast Majority Of Healthy Women Will Become Unhealthy!Monday, June 4, 2018
Most healthy women, who live long enough, will eventually become unhealthy.
So it should not at all come as a surprise to anyone, that the vast majority of women with “healthy” obesity (a misnomer, as in my view, the medical term “obesity” should only apply to people who already have health problems attributable to abnormal or excess body fat), eventually end up with “unhealthy” obesity.
This, essentially, is the gist of a paper by Nathalie Eckel and colleagues, published in The Lancet.
In their study of 90,257 participants of the Nurses Health Study, who were followed-up from 1980 to 2010 for incident cardiovascular disease (representing over 2 million person-years of follow-up), they found that around 80% of metabolically healthy women with obesity converted to metabolically unhealthy obesity over the course of follow-up.
But one might say that this was only marginally higher that the 70% of metabolically healthy “normal weight” women, who also converted to metabolically unhealthy over the 20 years of observation. In fact, the population-attributable risk of the latter group was much higher, as it consisted of almost 10 times the number of women than in the former.
While the risk of cardiovascular disease was statistically elevated (by about 40%) in the metabolically healthy women with obesity, this risk was 243% higher in metabolically unhealthy women with normal weight, 260% higher in metabolically unhealthy women with overweight and 315% higher in metabolically unhealthy women with obesity, all compared to metabolically healthy women with normal weight.
So, yes, women with metabolically “healthy obesity” have a high risk of becoming metabolically unhealty and developing cardiovascular disease, so are metabolically healthy normal-weight women.
Overall, I believe it is safe to say that the vast majority of metabolically healthy women (regardless of body weight) will eventually become metabolically unhealthy, at which time their risk for cardiovascular disease increases.
Bottom line, everyone (not just women with obesity) will benefit from efforts to stay as metabolically healthy as possible for as long as possible – fortunately, we know that healthy diets and regular physical activity (while not necessarily preventing weight gain) can help maintain metabolic health, irrespective of current body weight.
Clearly, living as healthy as possible is not just good advice for women with obesity – who would have guessed?
p.s. although this was a study in women, I have no doubt whatsoever that the findings also apply to men – most metabolically healthy men will eventually become metabolically unhealthy over the course of their lifetime.
