Radio Farda reported that Baghi's wife and daughter have also been sentenced to prison in connection with their participation in a conference abroad.
Their lawyer has said that they will appeal against the sentences.
The convictions are the latest in a series of rulings against activists and scholars accused of threatening Iran's national security.
Baghi has spoken out against the detention of U.S.-Iranian scholar Haleh Esfandiari, saying that she has not been given the right to defend herself.
