Eunice Kennedy Shriver, who was hospitalized for a week for hypothermia after a sailing trip, has been released.

Shriver, 83, became chilled after an Aug. 8 sailing trip. She was taken first to Cape Cod Hospital and then transferred to Massachusetts General Hospital.

Massachusetts General spokeswoman Donita Boddie said Shriver was released Saturday.

Shriver is the fifth of Rose and Joseph Kennedy's nine children and the mother of Maria Shriver, the television journalist who is married to California Gov. Arnold Schwarzenegger. She is the sister of U.S. Sen. Edward Kennedy and former President John F. Kennedy.

Shriver founded the Special Olympics and is married to Sargent Shriver, the first director of the Peace Corps.
