I'm interested in knowing the incidence of the following
disease/impairments/risk factors amongst Brazilians aged 65 and over:
 1) % of 65+ with arthritis
 2) % of 65+ with depression
 3) % of 65+ who are obese

Up-to-date figures please - 2005 preferred. Please cite sources and
likely quality of data.

If figures for wider population of Brazil (i.e. % of total population
with 1, 2 and 3) are easily available and supplied, will tip well
(25%).

Brazil-based answerer preferred, failing that a Portuguese-speaker would be great.

Thanks
