Those who consider Lula's administration as bad or terrible increased marginally to 27.9% from 27.2 four months ago, it showed.
The rating of the leftist president's performance edged up to 55.2% from 54.9% in September, while disapproval also rose slightly to 39.6 from 39.0%, the MDA poll commissioned by the transport sector lobby CNT.
Lula gets his best approval ratings among lower-income Brazilians and in poorer northeastern Brazil, his political bastion.
He does badly among higher income groups and evangelical Christian voters, MDA said.
MDA polled 2,002 people in person between Jan. 18-21 and the poll has a margin of error of 2.2 percentage points.
