Is There A Link Between Sedentary Lifestyle and MGUS/SMM/MM?

I understand that there has been at least one study suggesting that females who remain seated much of the day most days over the long term are at higher risk of monoclonal gammopathies (actually, I think it was specifically multiple myeloma). I didn't read the study (I'm male, so I didn't bother), and am now wondering if anyone knows if a possible link was made among a more broad demographic (i.e., males too).

Anecdotally, how many people here with MGUS, SMM or MM consider themselves to live a sedentary life?
