WASHINGTON (AP) — Consumer prices posted a slight gain in July, with higher costs for medical care and clothing offsetting declines for hotel stays and consumer cellphone plans.

The Labor Department said Friday that its consumer price index edged up 0.1 percent last month after no gain in June and a 0.1 percent fall in May. Core inflation, which excludes volatile energy and food changes, was also up a slight 0.1 percent in July.

Both overall inflation and core inflation have risen an identical 1.7 percent over the past 12 months. That shows that inflation pressures remain well under control. In fact, a separate inflation gauge favored by the Federal Reserve has been slowing this year, raising concerns that inflation is falling farther from the Fed's 2 percent goal.

The Fed has raised its benchmark interest rate in March and June, and has signaled it plans a third rate hike before year's end. But private economists say the Fed may stand pat for the rest of 2017 unless inflation accelerates in coming months. The Fed's preferred inflation gauge showed a 12-month price gain of 2.2 percent in February, but its latest reading has slowed to a gain of just 1.4 percent.

Fed Chair Janet Yellen has blamed the slowdown on temporary factors such as a price war in the cellular phone industry that has pushed monthly mobile phone charges down. But she has also indicated that if her view is proven wrong, she is ready to support a change in the Fed's plans for rate hikes. The Fed meets again in September. Analysts believe it will keep rates unchanged and may not hike again until December.

For July, the CPI report showed that monthly wireless phone charges dropped 0.3 percent. They are now down 13.3 percent over the past 12 months, the biggest 12-month decline in cell phone charges in 16 years.

The costs of hotel and motel stays plunged a record 4.9 percent in July, the biggest one-month on records that go back to 1997.

Clothing costs, which had been falling, rose 0.3 percent in July. Medical costs showed a 0.3 percent increase in medical services and an even bigger 1 percent jump in medical products such as drugs.

Energy costs dipped a slight 0.1 percent in July with the cost of gasoline unchanged. Food costs were up a modest 0.2 percent.
