The study basically said body mass projected the same results? I can't help but think that the typical foods we consume as an 'advanced' nation are ones of convience and ones that primarily are addictive and unhealthy; this has to be a significant contributing factor. Along with low activity, more cerebral work, vs physical labor has to be a play as well.

Edit: they did mention that comorbidities, including diabetes were a contributing factor. Sugar is the root of all evil, and Americans for sure love their corn syrups... after all it is their cash crop.

Oddly enough, recently there was the company Lipocine in the news that created a new drug that basically is designed to restore normal testosterone levels in men: TLANDO.
