ROME, Dec 10 (Reuters) - Italian industrial output fell 1.0% in October from the month before, data showed on Wednesday, in a renewed sign of weakness for the country's long-struggling manufacturing sector.

A Reuters survey of 12 analysts had pointed to a 0.3% decrease, after a 2.7% rise in September had reversed a fall of the same size in August.

October's decline extended to all the main industrial sectors with the exception of energy, national statistics agency ISTAT said, driving a 0.9% fall in the August-October period compared to the previous three months.

On a work day-adjusted year-on-year basis, industrial output in the euro zone's third-largest economy was down 0.3% in October versus a forecast for a 0.2% increase.

ISTAT last week forecast that the Italian economy will grow by 0.5% this year, trimming a previous estimate of 0.6% made in June.

The Italian government's most recent target, made in October, also envisaged growth of 0.5% this year, following a 0.7% rate in 2024.

In the third quarter, gross domestic product increased by a marginal 0.1% following a 0.1% contraction in the previous three months.

However, a positive signal arrived last week from a purchasing managers' survey of the manufacturing sector, which signalled a return into growth territory in November.
