1 in 4 American teen has an STD? Really?

New study by the CDC saying 1 in 4 girls in America between the age of 14-19 has an STD.

I found another article that says that this means that just over 3 million girls have an STD.
Meaning that this survey of 838 girls was suppose to represent 12 million girls. Before running off and giving your girls a shot of the Merrick vaccine, here are some things to consider.
The survey was conducted by the CDC. Centers for Disease Control.

First do the figures sound exaggerated?

Where did they find the girls? Where the girls compensated? If the girls were going for some kind of Birth Control or exam, then this means that they were already having sex, or thinking of it, and then are they an accurate sampling of teenage American girls?

[quote]Researchers analysed data from a nationally representative sample of 838 US girls aged 14 to 19. [/quote]

So 838 girls of unknown racial, religious, socio-economic, educational, backgrounds are suppose to represent 12 million American girls ages 14-19. Why am I not convinced?

[quote]It found that nearly half of the African-American girls surveyed had at least one STD, while the rate was 20% among white and Mexican-American teenagers. [/quote]

It says that half of the African-American girls surveyed had at least one STD. This tell me nothing. How many African American girls were surveyed? 10 800? If your sample is too high or too low a percentage of one group, you will get figures that are inaccurate either way. Eg. If they interviewed just 10 African American girls and 5 had an STD then the figures would be correct for the survey, but generally wrong for the larger American population.

Also in America if you are bi-racial and have 1 drop of black blood, in many cases you are still required to consider yourself as African-American. Don't tell me that did not throw off the figures.

Great so a survey that is suppose to represent 12 million American girls only surveyed African-American girls, white girls, and not even Latina girls, but only Mexican-American girls.

So what happened to Asian girls, Latina girls that are not Mexican-American, South East Asian Indian, Native American, etc. We are suppose to use this sampling to represent all American girls, but not all American girls were sampled?

[quote]Human papillomavirus, or HPV, affected 18% of the girls surveyed, chlamydia 4%, trichomoniasis 2.5%, and herpes simplex virus 2%. [/quote]

So if we took out HPV, which I do believe is what is at the heart of this survey and the Merrick agenda to have all girls vaccinated with their STD vaccine, then we have 8.5% with an STD.
[quote]he CDC is recommending annual chlamydia screening for all sexually active women under 25, and HPV vaccines for girls aged 11 to 12, followed by booster injections. [/quote]

I think this is what is at the heart of this survey, and I really think it's a shame that it seems that the CDC is going to be used to push this Merrick agenda on young girls, but also on some populations more than others, as usual. The drug also may not be fully safe according to the aritcle below.

If the CDC can provide the correct demographics that they used, socio-ecomocic status, religious, etc, that would be a good start. Was there compensation involved?Without these facts and figures can we truly believe that this was an accurate sampling, and that these figures are truly representative of all American girls between the ages of 14-19?

I think not considering a large demographic of the population seems to have been excluded. Asian, East Asian, Native American, Latina of a none Mexican origin, Middle Eastern, etc.
I would love to see this survey done again with a larger sampling, and a using demographics that match the demographics of the American population. Again if we are only using kids that are having sex, or thinking about having sex again what kind of accurate figures will this produce?
