BRFSS?
You have got to be kidding. This was a discussion about STIs.
Who in their right mind would look at BRFSS for STI Dx data? That is not why we created or funded the BRFSS. And STI Dx data is not what they collect,
I have absolutely no idea what point you are trying to make.
It sounds like you are suggesting that CDC does not provide to the public, free, easy to find, rather new Dx data on STIs.
CDC not only does that they have been doing that for age. Totally free and easy to find.
A STI such as syphilis is a reportable disease.
It’s reported to the state HD then to CDC. On all new syphilis Dx an interview is done . Or attempted for the few Dx that can’t be found and may never be interviewed.
In that syphilis interview they will sooner or later get to this question——“who have you had sex with”—-in the past 3 months for P, 6 months for secondary, or a year for early latent.
If you are interviewing a 40 yo man with primary or secondary or EL syphilis you are not asking nor do you care that in college he may have had sex with his male room mate.
What happened years or decades ago is a non issue.
You are only concerned about the last 3-6-12 months.
And you don’t care how the person self identifies. A non issue. Gay straight bi undecided——no one cares.
You only care about risk, who they have had sex with in the past 3-6-12 months And if they have only had sex with a female they will not be listed as a msm. Despite what happened in college years ago.
If they have had sex with a man , even once within the past 3-6-12 months , they will be listed as a MSM. The code was C-4 back in the day.
Do these men often lie about who they have had sex ? Often. That is why a well trained interviewer is needed to do the job.
It takes time , but sooner or later the interviewer will have a pretty good idea what the client or patient has done and at least an idea of what sex they had sex with.
Having interviewed many of these men , I do realize many actual names will never be known. ,
Risk is important how people self identify is not.
