Holy crap!!!! That is bullshit. High cholesterol is NOT a disease. Most people can't help it as they also have genetic predispositions. This is a very slippery slope and a gross overstep on personal privacy and possibly a HIPPA violation to force people to disclose such things
Well, like the tobacco use and the BMI, I think the point is that if you're not within their (again, the insurance company, not the job) limits, you have to participate in some sort of program to lower or manage your cholesterol. As long as you continue to do that work, I think you get the lower premiums. (I've read a packet that I just got in the mail from them, I know nothing other than what the insurance company tells me in that brochure). The job doesn't necessarily know any of it, it's between you, your doctor, and the insurance company. I suppose HR knows because they'll know what's coming out of your paycheck for your monthly premiums, but then again, I can chose to not participate at all and just accept the higher rate.
It almost reminds me of getting a new landline hooked up back in grad school and they wanted money to keep me out of the phone book. I got mad and ATT actually said, "privacy has a price." I went off about how that's extortion, lol, "Pay us money or we'll print your name, address, and telephone number in a book and distribute it to everyone in town!" Did I just hijack my own thread? oops.
