I don't deny for a second that white girls are the dirtiest girls out there but all OP presented was an MSNBC article that doesn't even provide stats. And we need more information about the 2 studies referenced in that article.
"Dr. Carolyn K. Holland, a pediatric emergency room specialist at Cincinnati Children’s Hospital, studied the hospital's records of 293 patients aged 13 to 21 with abdominal, urinary or gynecological symptoms that could indicate an STD. The records, from 2010, revealed that 71.3 percent of young black women were tested, compared to only 18.6 percent of young Caucasian women.
Overall, young black women had a 2.6 times greater chance of having their sexual history documented on medical records. Of those who said they were sexually active, 87 percent were tested for STDs, but only 58 percent of young Caucasian women who said they had sex were tested.
Even young black women who said they did not have sex were tested, and at far higher rates than whites: 30 percent compared to 2 percent.
'Troubling' disparities
The disparities are "troubling," Holland told msnbc.com. Any bias, even if unconscious — in this case, the presumption that young black women are more promiscuous than whites or more likely to lie about sex — can cause doctors to miss a diagnosis.
“Everybody should have their sexual history collected,” Holland said. “My practice now is that if you are sexually active and come in with a complaint — urinary, vaginal — yes, I am testing you.”
Holland said, “many do not have primary care doctors; an ER visit might be the only time they can get tested.”
The importance of checking a young patient's sexual history in the ER is underscored by researchers at Children’s Hospital of Philadelphia. In the other study,Dr. Monika Goyal, a pediatric emergency room physician, examined the records of 236 teenage girls, ages 14 to 19, all of whom had come into her hospital’s ER with symptoms that could indicate an STD. Of those that were tested, 26.3 percent turned up positive for an infection, sometimes more than one."
That was more info from the article. I'll ask my cousin for the studies.
