Obésité et crise cardiaque

Si vous aimeriez avoir une opinion critique et scientifique sur certaines découvertes qui touchent à la nutrition et à l'obésité et que vous n'êtes pas encore allées vous promener chez Sandy de Junkfood Science, qu'attendez vous?

Ok, c'est un peu de la "lecture de rat de bibliothèque", mais c'est tellement intéressant! J'assume mes moustaches de rate!

Cette fois ci, elle nous parle d'obésité et de crise cardiaque en commentant une étude effectuée au Danemark qui n'a absolument été mentionnée dans les médias. On s'en étonne... Pourtant, il est toujours intéressant d'avoir les deux coté d'une médaille à observer!

Je vous laisse sur la conclusion de l'auteure de l'étude:

Although our finding may seem controversial, it is not surprising. A recent meta-analysis of 40 studies including 250,152 patients with coronary artery disease also concluded that total mortality was lower in overweight and obese patients, and an overview of 32 studies on mortality risk in elderly people aged ≥65 years showed that BMI in the overweight range was not associated with increased mortality and moderate obesity was only associated with a moderately increased mortality risk. As mean age of our cohort was 72 years, it is interesting to note that studies on elderly patients >70 years of age show an inverse association between BMI and mortality as also seen in our study.

We found that underweight stroke patients clearly had the highest mortality. Lower BMI is highly associated with smoking, but the finding was independent of smoking habits and prevailed also after stratification on smoking- nonsmoking. This finding is consistent with those from other studies. Underweight may be the result of another underlying disease thus increasing mortality risk. However, in studies with the same result as ours, underweight persons had the highest mortality risk even after exclusion of subjects who had died within 2–5 years after inclusion. BMI is a reflection of both body fat and lean mass. Low BMI may be the result of reduced lean mass as a consequence of inactivity because of reduced mental and physical health.

On the other hand, persons with a high BMI may in addition to an increased amount of body fat also have a higher lean mass as a consequence of an active lifestyle and otherwise good mental and physical health.
