American consumers lost a little confidence this month amid worries that slowing economic growth will hurt the job market, the University of Michigan says.

The university's consumer sentiment index slipped to 91.7 in February from January's reading of 92. A year ago, the index stood at 95.4.

Consumers' assessment of current economic conditions was a bit higher than last month. But their outlook dimmed.

Richard Curtin, chief economist of the university's surveys, said Americans are worried about a slowdown in U.S. economic growth.

The Commerce Department reported Friday that the economy grew at an annual pace of just 1 percent from October through December, though that was an improvement over an initial estimate of 0.7 percent.
