What's your opinion on "scaring" people into living a healthy lifestyle?

I’m at a minor league baseball game and it’s being sponsored by the American Heart Association, and a doctor just spoke to the crowd about how heart disease kills 33 women a day and that everyone should get their blood pressure checked. He also encouraged everyone to stop eating their hotdog and sugary soda.

Do you think this tactic works? I think it’s extremely counter productive, and it doesn’t get the message across very well in my opinion. Your thoughts?
