(Adds central bank comments)

BRATISLAVA, Sept 3 (Reuters) - Slovakia's economic growth slowed in the second quarter to an annual 7.6 percent, but it remained one of the best-performing European Union economies and its 2008 forecast stayed on track, officials said on Wednesday.
The data, a deceleration from the 8.7 percent growth seen in January to March and the record 10.4 percent full-year growth in 2007, matched a previous flash estimate released last month.
"The data were in line with central bank's expectations," central bank Vice Governor Viliam Ostrozlik told Reuters after the cabinet meeting in central Slovak town of Banska Stiavnica.
In its quarterly forecast, the Slovak Statistics Office said it expected full-year annual growth of 7.9 percent this year, while inflation would be 4.1 percent according to local methodology.
Analysts said the growth data were more or less in line with expectations.
"Household consumption slowed down as we expected. Consumption in the first quarter was high, but it has slowed to a normal level," said Viktor Strba, an analyst at ING.
"In the fourth quarter there will be a slowdown from the base effect. But (the full-year growth outlook) is reachable."
The growth figures lagged fellow EU newcomer Romania, which grew 9.3 percent in the second quarter, drawing concerns of overheating from analysts. But Slovakia beat central European peers Poland and the Czech Republic, which had 5.8 and 4.5 percent. Regional laggard Hungary was at 2.2 percent.
Ostrozlik said slowing household consumption was a positive factor in terms of possible future inflation pressure, but he said the growth structure still needed to be analysed.
"It is positive that gross capital formation in the second quarter has risen more significantly," he said.
Slovakia, which will join the euro zone on Jan. 1, has had one of the EU's highest growth rates since 2004, a result of billions of euros in foreign investment that has produced a boom in car and electronics production.
There is also a surge in household spending, fuelled by rising incomes that have allowed consumers in this ex-communist state of 5.3 million to splash out on items like new cars, household appliances and luxury apartments for the first time.
"Wage growth in the second quarter was a touch faster than productivity growth by 0.2 percentage points," Ostrozlik said. "I see risks in unjustified wage growth ... if it would exceed productivity growth on a long-term basis."
Slovakia's GDP per head in purchasing power parity is expected to be 71 percent of the EU average this year.
Fast economic growth has boosted budget revenues, helping finance the welfare agenda of leftist Prime Minister Robert Fico and allowing him to cut the fiscal deficit to below the euro adoption threshold without spending cuts.
