The nation's industrial output rose a seasonally adjusted 0.8 percent in December from the previous month, revised down from a preliminary 1.0 percent gain, the trade ministry said on Monday.

The index of output at factories and mines stood at 98.7 against the base of 100 for 2010, compared with 98.9 in the initial data released Jan. 30.

The downward revision was attributed to sluggish production of coffee and other beverages as well as pharmaceutical products, which was not reflected in the preliminary report, a ministry official said.

Shipments increased 1.0 percent, slightly less than a preliminary 1.1 percent projection, while inventories shed 0.7 percent, compared with a decrease of 0.4 percent.
