I've never seen a study on it. There may well be some limited effect within the US for that specific period, but I'd be very surprised if it persisted. It could have also gone the other way... a bunch of people decided it was 'the end-times', so they all had unprotected sex like crazy to cope and 'go out with a bang' (pun intended).
