A quick search of the New England Journal of Medicine site reveals partly similar results:
Since July 1996:

SAS 458 articles
Stata 160 ...
SPSS 140 ...

I stress quick because I did not check each article to see if some may have been referring to the Scandinavian Airlines or not, or a building at MIT etc... But if one is to look a little into these numbers and shorten the timespan to be more recent, say:
Since July 2000:

SAS 298 articles
Stata 132 ...
SPSS 100 ...

and even more recently:
Since July 2004:

SAS 107 articles
Stata 87 ...
SPSS 33 ...

Perchance evidence of Sebastian's trend??
What the hey, let's look at the last year:
Since July 2005:

SAS 55 articles
Stata 72 ...
SPSS 14 ...

Hmmm Should I have reported,

Stata 72 articles
SAS 55 ...
SPSS 14 ... ?

m.p.

Certainly, SAS is the package that is most widespread in medicine (at least in Europe). But Stata is becoming more and more accepted among epidemiological/ public health researchers. Just check the top-notch journals (as measured by the impact factor ;) ) and you will find a lot of papers using Stata (eg, Jama, 2006,295(6):676-80).

Two minutes on the JAMA site gave the following information: in full text articles since 1992, mention of specific statistical packages is as follows:

SAS: 974 papers
Stata: 287 papers
SPSS; 246 papers
Other packages (SPlus, Statistica, Egret, NCSS, JMP) 20 each or fewer
